Unit Notes:
Notes to Teacher:
 A book is a great lead in for a lesson.
 All experiments need to be set up ahead of time.
 All examples need to be tried by the teacher before doing it with
the students.
 Some examples of a finished product need to be put together
ahead of time.
 Materials can be modified and changed as necessary.
 Be sure you have all rules in place before an experiment begins.
 This unit is designed to be interactive and fun.
LEP Modification: Reading materials that students will read
pertinent to the unit should be selected with students’
reading levels in mind. It is usually possible to select
materials which will support the lesson, but at a lower level
so that the LEP student can comprehend the content
material.
Unit Overview:
-3-
Unit Overview:
The human body unit gives students an opportunity to observe and
investigate the form and functions of our skeletal and muscular
systems. The students will get hands on experience through
identifying different bones, joints and muscles using diagrams and
charts and then locating each on their own body. They will
explore how the skeletal system provides support, protection, and
locomotion with assistance from the muscular system. The
students will build models and acquire the vocabulary by focusing
on a particular area of the body. Throughout the investigations the
students will use scientific process skills to observe, communicate,
predict, classify, measure, and infer information about the skeletal
and muscular systems.

Lesson One: I Like to Move It
Objectives:
4.01 Identify the skeleton as a system of the human body
4.05 Observe and describe how muscles cause the body to move
LEP Objectives: Students will write a minimum of three sentences
to tell how the body moves during different physical activities. A
word bank/list or working with a partner would be helpful for LEP
students.
Essential Question: How does the body move?
Time: one 30-minute period
Content Blast:
The skeleton is a system of the human body. It is the framework that
supports and protects the body. It also works with our muscles to move
our body. We have 206 bones in the adult skeleton.
LEP Modification: It would be helpful to read Building a House by
Byron Burton to the LEP students to draw the analogy of the frame
and systems of home construction to those of the human body.
Another suggestion is to use a 3-D skeleton model or replica, if
your school has one, to build skeleton background knowledge.
Materials:
Per Student Pair:
one jump rope
Per Class:
chart paper
Process Skills: Observe, Communicate, Infer, Predict
Engage:
Demonstrate several ways to appropriately jump rope.
-8-
Explore:
Students will work in pairs to observe each other jumping rope. One
student records his or her observations in their science notebook while the
other jumps rope. Students will then change places and repeat.
Explain:
Have a class discussion on what the students observed while they were
jumping. Create a class chart listing all of the ways that the body moved in
order to successfully jump rope. Ask the students what was allowing their
bodies to move in those ways. Lead them to the discovery of bones and
muscles working together to allow those movements.
Elaborate:
Have the students act out other various scenarios where they need to
move their bodies. (i.e. swimming, climbing, hiking, etc.) Compare these
activities to the jumping rope activity. Ask if their bodies move in the same
way.
Evaluate:
Have the students write a reflective paragraph in their science notebooks
about the ways that the body moves in order to complete various activities.
They should include the reasons that their bodies are able to move in these
ways.
-9-
Lesson Two: Dem Bones
Objectives:
4.01 Identify the skeleton as a system of the human body
LEP Objectives: Students can tell that the skeletal system is one
of many systems in the human body. Students can list the four
main parts of the skeleton, but will need support for correct
spelling.
Essential Questions: How many bones are in the human body?
Time: two 45-minute periods
Content Blast:
See Lesson One
Materials:
Per Student Group:
diagram/poster of human skeleton sections (torso, arms/hands, legs/feet,
skull) See examples in lesson.
Per Class:
overhead/chart of class data table
Process Skills: Observe, Communicate, Predict, Measure, Classify
Engage:
Refer to Lesson One. Ask the students to recall how the body moved. Ask
the following questions: Do your bones move when you jump? Where are
your bones? How can you tell where your bones are? Have students feel
for the bones inside their bodies. Ask if they can feel all of the bones in
their bodies. Explain to the students that they will conduct an investigation
that will help them to determine how many bones make up their skeleton.
Have students predict how many bones total they believe are in the human
skeleton based on what they have felt in their bodies.
- 10 -
Explore:
Day One:
Divide the class into four groups. Provide each group with diagrams of two
human skeleton sections. For example, one group may receive the skull
and torso, another group will get the legs and arms, etc. Students should
use the diagrams to count the number of bones in that section of the
skeleton and record their conclusions in a data table like the ones below.
Skull Bones
Face Bones
Arm Bones
Torso Bones

Day Two:
Begin by asking the students if there was anything that surprised them from
the previous day. Explain to them that they are going to compile their data
onto a class data table in order to draw conclusions about the total number
of bones in the body. Provide them with a data table that they can record
their group results.
Class Data Table
Skeletal Sections
Group Totals
Average
Arm
Leg
Torso
Skull
Grand Total
Explain:
Once the totals have been recorded discuss the varying answers for each
group. Ask them if it is possible that some bones were missed. After this
discussion explain how averaging can help determine a more accurate
count for each section. Average the results for each section and then total
all of the averages together in order to obtain a skeletal grand total. Tell
students that the correct number of bones in your body is 206. Discuss
why their grand total may be different.
Elaborate:
Ask students the following questions: How will we know if we missed any
bones when we counted? What could we use to help us find out more
about bones? Discuss other ways of counting bones such as books,
x-rays, or a model skeleton. Students could choose to use other resources
to see if they can get a more accurate total.
Evaluate:
Students should be able to identify that there are four main skeletal
sections in the body and that each one is made up of many bones.

Lesson Three: Owl Pellets
Objectives:
4.03 Describe the functions of different types of joints
 Hinge
 Ball and Socket
 Gliding
4.04 Describe how different kinds of joints allow movement and compare
this to the movement of mechanical devices
LEP Objectives: Students will be able to complete a Venn
diagram comparing and contrasting rodent bones and human
bones with assistance.
Essential Question: What is an owl pellet?
Time: two 45-minute periods
Content Blast:
Owls are raptors that swallow their prey in pieces and are unable to digest
the fur, bones, scales, and teeth. After an owl eats, a pellet forms in the
stomach as the soft materials separate from the hard materials. The owl
then coughs up or regurgitates a pellet containing bones.
Materials:
Per Student Pair:
owl pellet (these can be purchased at a science supply store)
toothpicks
hand lens
rodent bone identification sheet (these can be found online)
envelope
human skeleton diagram
Process Skills: Observe, Communicate, Predict, Infer, Measure, Classify
*A virtual owl pellet dissection activity is available at www.kidwings.com.
Engage:
Read a book about owls. Discuss the things that owls eat.
- 13 -
Explore:
Day One:
Divide the students into pairs and give each pair an owl pellet, toothpick,
and hand lens. Have them examine the pellet and discuss what they think
it is. Students should draw the pellet and record qualitative and
quantitative observations in their science notebooks. Students will then
split open the owl pellet and classify the parts they find. Teacher should
circulate and discuss the findings with each group. Students should again
record observations into their science notebooks. Once each group has
recognized that the pellet contains bones, a whole class discussion should
ensue about the contents of an owl pellet. Students should save the bones
and teeth for Day Two of the lesson by placing them into an envelope. The
fur may be discarded at this time.
Day Two:
The teacher will review owl pellets and discuss the group findings. Hand
out a rodent bone identification sheet. Return each pair’s envelope
containing the bones collected on the previous day. Allow students time to
identify the names of the bones that they found in the pellet. Ask students
to determine if there are bones from more than one animal. Instruct
students to lay bones out and attempt to form a complete skeleton.
Explain:
Ask students the following questions throughout the lesson:
 What skeletons were found?
 What bones did you identify?
 Were there extra bones (i.e. two skulls) and what does this tell you
about the animal’s diet?
 Can you tell the function of a bone by its structure?
 How are these bones similar to humans?
Elaborate:
Students can complete this activity with another bird of prey’s pellets and
compare the findings to the owl pellets. Another option would be to use owl
pellets from another region of the country and compare those findings.
Have students create Venn diagrams detailing the similarities and
differences among various pellets.
- 14 -
Evaluate:
Give students a diagram of a human skeleton and have them complete a
Venn diagram comparing rodent bones and human bones.
LEP Modifications: Students, especially Intermediate level
students, should do this activity with a partner.
- 15 -
Lesson Four: Hard Bones
Objective:
4.02 Describe several functions of bones:
 Support
 Protection
 Locomotion
LEP Objectives: Students can tell that bones give the body
shape; help it move; and keep the important organs safe.
Students can list ways to keep bones strong.
Essential Question: What makes your bones strong?
Time: one 45-minute period
Content Blast:
Most children think of bones as hard, dry, white parts of the body. The
bones are hard, but they are definitely not dry. Bones are alive and are
made of a mix of hard materials and living cells. The hard part of the bone
is made mostly of calcium and phosphorous. These minerals give bones
their strength. Inside bones is a soft tissue known as marrow. Cartilage
is a flexible tissue that covers the ends of some bones. It helps to protect
bones from grinding against one another. The inside of a bone do not add
strength to the bone, but it does make new blood cells and produces germfighting white blood cells.
Materials:
Per Student Group:
two toilet paper rolls
heavy books
overhead, poster, or diagram of inside of a bone
Process Skills: Observe, Communicate, Predict, Classify, Infer
Engage:
Review the names of some of the bones from the previous lesson. Point to
various bones and say its name. Examples are skull, ribs, jaw, collarbone,
etc. Ask the students how strong they think bones are. Pose questions
such as “Are bones stronger than your pencil, stronger than a ruler,
- 16 -
stronger than a piece of chalk, stronger than a piece of wood, etc.” These
questions will give students a base to form their own comparisons.
Explore:
This activity will give students an idea of bone strength. Using a toilet
paper roll, place the roll on the table so that it stands on its end. Tell
students the toilet paper roll represents the bone. Tell students we are
going to place a book on top of the roll. Have students predict what will
happen to the roll when a book is placed on top of it. Will the roll be able to
hold it or will the roll be bent or broken? Place the book on top of the roll.
It should easily support the book.
Explain:
Tell students that bones are not solid, but are hollow like the toilet paper
roll. As we saw, a hollow tube is as strong as a solid and is able to support
a lot of weight. As bones grow, calcium and phosphorous are put into the
cartilage. They become strong and are able to support and protect our
body. Discuss with students ways to keep your bones strong through a
healthy diet and exercise.
Elaborate:
Set a second book on top of the toilet paper roll. Once again it should
easily support the weight. Have students make another prediction about
how many books the toilet paper roll will hold before it bends or breaks.
Discuss with students why your bones need to be strong.
Evaluate:
In science notebooks have students write at least two ways to keep their
bones strong.
- 17 -
Lesson Five: Soft Bones
Objectives:
4.02 Describe several functions of bones:
 Support
 Protection
 Locomotion
LEP Objectives: Students can tell that bones give the body shape;
help it move; and keep the important organs safe. Students can
list reasons why bones would be harmed or remain healthy.
Essential Question: What makes our bones unhealthy?
Time: one 30-minute lesson, 15-minute follow-up seven days later
Content Blast:
Minerals cause bones to be strong. When the minerals are removed,
bones become soft and pliable.
Materials:
Per Student Group:
one uncooked chicken bone such as a wing or wish bone (thoroughly
cleaned and washed in hot water)
jar with a lid
vinegar
Process Skills: Observe, Communicate, Predict, Infer
Preparation:
The chicken bones should be cleaned and allowed to dry overnight prior to
completing this lesson.
Engage:
Read a book about ways to keep your bones strong. (Refer to resources
list.)
Explore:
Give each student group a chicken bone. Ask them to record observations
in their science notebook about the bone’s color, size, shape, texture, and
- 18 -
strength. Ask students to predict what would happen if they left the bone in
a jar that is covered with vinegar for seven days. Record these predictions
in their science notebooks.
After seven days, remove the bone and rinse with water. Have students
test flexibility of the bone by bending it. Observe and record the bone’s
color, size, shape, texture, and strength in their data table.

Explain:
Tell students that the minerals were removed from the bone by the vinegar.
Have them discuss which parts of the bone became soft first and have
them predict what would happen if they were to allow the bone to remain in
the vinegar even longer. Discuss ways to ensure that minerals do not
leave their bones. This discussion should include eating a healthy diet and
exercising regularly.
Elaborate:
Have students place the bones back into the vinegar for another week.
Observe the changes that occur.
Evaluate:
Students should be able to identify the changes in bones when the
minerals were removed. Have them create a T-Chart identify factors that
keep bones healthy and factors that harm our bones.

Lesson Six: Gliding, Ball and Socket, Hinge, Oh My!
Objective:
4.03 Describe the functions of different types of joints:
 Hinge
 Ball and socket
 Gliding
4.04 Describe how different kinds of joints allow movement and compare
this to the movement of mechanical devices
LEP Objectives: Students will be able to name the three types of
joints, and show an example of each in the body.
Essential Question: What are the different types of joints?
Time: one 60-minute period
Content Blast:
Joints are needed to provide flexible connections between bones. There
are two categories of joints; immovable joints and movable joints.
Immovable joints are places where bones fit together too tightly to move.
They are mostly found in the skull. Movable joints are places where bones
can move easily. These types of joints are gliding joints, ball-and-socket
joints, and hinge joints. Gliding joints allow some movement in all
directions and can be found in the hand and wrist. Ball-and-socket joints
allow bones to move back and forth, in a circle, and side to side. Hinge
joints allow bones to move back and forth in one direction.
Materials:
Per Student:
one labeled index card with an example of a joint and/or a type of joint
diagram of human skeleton
Per Class:
hinge
measuring spoon
lollipop
- 21 -
Process Skills: Observe, Communicate, Predict, Infer, Classify
Engage:
Ask students if they can bend their bones in any place. If students say
“yes” ask them to bend their arm in any place other than their elbow or
wrists. Students should not be able to bend their arm except at their elbow
or wrist. Explain to students our body has joints. Joints are where bones fit
together. There are two main categories of joints, immovable joints and
movable joints. Have students try to define immovable and movable. Ask
students to try to move their skull. They might look confused, but hopefully,
they will quickly see their skull is a type of immovable joint. The bones fit
together too tightly to move. Ask students to bend their knee, bend their
elbow, move their hand up and down, and move their arm around. Tell
students these are movable joints because the bones can move easily.
Explore:
Discuss with students that there are three main types of movable joints.
Have students bend their knee. Explain this is a hinge joint. A hinge joint
is like a door hinge that allows a door to open and close. Show students an
actual hinge from a door. Have students discuss how the hinge is similar to
the movement of the knee. Other examples of hinge joints are elbows and
bending your fingers at the knuckle. Next, have students move their arm in
a circular motion. Explain to students this is a ball-and-socket joint. The
ball of one bone fits into the socket, or cup, of another bone. Use a
measuring spoon (socket) and a lollipop (bone) to show how ball and
socket joints work by placing the lollipop inside the spoon and moving it
around. This joint allows bones to move back and forth, in circle, and side
to side. Another example of a ball and socket joint is your hip. Have
students move their wrists and ankles. Explain that these bones can slide
against one another. This joint allows some movement in all directions.
Explain:
Ask the students the following questions:
 What do you call the place where two bones come together?
 What are the three types of joints?
 How do your joints help you move?
 What would happen if you didn’t have your joints?
- 22 -
LEP Modifications: It would be very helpful to the LEP students
to use an actual skeleton model or replica, if you have one in
your school. There are smaller models available in some of the
teacher supply stores for a very reasonable price. Tactile
learning is very helpful for these students.
Elaborate:
Give one group of students index cards labeled with the different types of
joints just discussed. For example: hinge- a joint that moves back & forth.
Have that group of students stand in different areas of the classroom. Give
the remaining students names of body parts we have studied. For example
knee, elbow, wrist, etc. The students that have cards with names of body
parts will then classify themselves corresponding to the correct joint.
Students should discuss with their group if the match is correct. For
example, a shoulder should not be able to stand with the hinge joint.
Evaluate:
Give students a diagram of the human skeleton. Have students color code
the three types of movable joints on the diagram as follows:
Hinge – Red
Ball and Socket – Green
Gliding – Blue
Be sure that students are coloring the points where the bones meet rather
than coloring in the bones.
LEP Modification: To assure that the students understand and
complete this assessment correctly, they should work with a
partner, especially LEP students who are Intermediate level.
- 23 -
Lesson Seven:
Back Breaker
Objectives:
4.02 Describe several functions of bones:
 Support
 Protection
 Locomotion
4.04 Describe how different kinds of joints allow movement and compare
this to the movement of mechanical devices.
LEP Objectives: Students will be able to re-create the activity with the
pipe cleaners and straws to show understanding of the lesson’s activity.
Essential Question: How does the spine aid in the body’s ability to
move?
Time: one 45-minute period
Content Blast: By having many small bones, instead of, fewer large ones,
the spine has increased flexibility. There are 26 bones that make up the
backbone. These bones can be called vertebrae. Inside the backbone is
the spinal column. Each bone or vertebrae is separated by cartilage. The
cartilage assists in movement and absorbs shock when necessary.
Materials:
Per Class:
human skeleton diagram or poster
Per Group:
three pipe cleaners
three plastic straws
scissors
Process Skills: Observe, Communicate, Predict, Measure, Classify, Infer
- 24 -
Engage:
Refer to a skeleton diagram or poster. Point to the back and have students
recall this bone is called the spine. Ask students to predict if they think the
spine is made up of one large bone or several small bones.
Explore:
Pass out materials to each group. Have students place one pipe cleaner
inside one straw. Tell students the straw represents the backbone and the
pipe cleaner is what is found inside the backbone. Ask students if they can
bend the straw without creasing it. After several attempts, students should
find that they are unsuccessful at this task. Next, have the students take
the another straw and cut it in half and once again put one piece of pipe
cleaner through the two pieces of straw. Students can now bend the straw,
but this represents if the spine could only bend at a ninety degree angle.
Now, take the final straw and cut it into five pieces and thread the last piper
cleaner through the five pieces. Have students bend this last straw and
compare it to how well the other two were able to bend.
Explain:
Students should conclude that the last straw is most like the body’s
backbone. Explain that the spine has many small bones divided by discs
made up of cartilage. This cartilage is what allows the backbone to move
so easily. If the spine had one large bone, it would be like the first straw
and we would not have any mobility. If the spine was like the second
straw, we would have limited mobility.
Elaborate:
Students could use another straw and create 26 “discs” in order to visualize
what the 26 bones in the backbone look like.
Evaluate:
Have students write in their science notebooks about the activity. Have
students explain why the spine needs to be made of several small bones
rather than one large bone. Have a word list for students to refer to while
writing in their science notebooks.
LEP Modifications: The word list is a great idea for LEP students, and
they may also need the support of working with a partner to complete
the evaluation. Modify the length of the explanation and the entry for
the Science notebooks for LEP students.

Lesson Eight: The Amazing Opposable Thumb
Objectives:
4.03 Describe the functions of different types of joints
 Hinge
 Ball and socket
 Gliding
4.04 Describe how different kinds of joints allow movement and compare
this to the movement of mechanical devices
LEP Objectives: Students will be able to describe actions that
they were able to do in this activity and write about the
importance of the human thumb.
Essential Question: How important are thumbs for doing everyday
tasks?
Time: one 60-minute period
Content Blast:
One of the most important joints is the thumb. Humans have an
opposable thumb. We can touch our thumb to the tips of our four other
fingers. The strength of our grip is also unique. These two features make
our thumbs “thumbs up”. 
Materials:
Per Class:
several rolls of masking tape
Per Student:
data table with tasks to complete
blocks
paper clips
pencil sharpener
pencil
shoe with laces
book
paper
- 26 -
Process Skills: Observe, Communicate, Predict, Classify
Engage:
Have students try to pick up their pencil without using their thumb. Discuss
strategies and obstacles for completing this task. Was it difficult or easy to
complete?
Explore:
Inform students that they will be performing a series of tasks without the
use of their thumbs. Demonstrate how to tape a student’s thumb to their
index finger by wrapping masking tape around until the thumb is secured
against the index finger as shown in the picture below. Choose student
helpers to assist in getting all of the student’s thumbs taped. Both hands
should be taped. Once all of the students are taped up distribute the data
table below with the assigned tasks.

 Which tasks were difficult and why?
 What did you do to overcome these obstacles?
 What are the advantages of an opposable thumb?
Elaborate:
Have students continue attempting tasks without their thumbs at home.
Tell them to try to complete their normal evening routines without the use of
their thumbs.
Evaluate:
Students should write a reflective paragraph on what it was like to live
without thumbs. They should include the importance of the thumb when
completing everyday tasks.
LEP: It may be difficult for an LEP Novice or Intermediate level
student to write a reflective paragraph. An appropriate evaluation
for these students might be to orally share with a partner to help
them complete the evaluation.

Lesson Ten: Putting It All Together
Objectives:
4.05 Observe and describe how muscles cause the body to move.
LEP Objectives:
Essential Question: How do muscles move bones?
Time: two 60-minute periods
Content Blast:
Bones cannot move by themselves. They need muscles in order to move.
Muscles called skeletal muscles are attached to a bone and allow
movement. These muscles pull bones to move them. A strong band of
tissue called a tendon connects a muscle to a bone. Muscles can be
damaged. A muscle tear occurs when the fibers of a muscle are separated
by a sudden force or stretching. The quick start of runners who run short
dashes can result in a tear. A muscle strain occurs when muscles that
have not been exercised for several weeks are overused.
Materials:
Per Student Pair:
two bendable straws
one rubber band
two paper clips
scissors
pushpin (optional)
Process Skills: Observe, Communicate, Predict, Infer
Engage:
Have students put one hand, palm up, against the under side of their desk
and push upward. With their other hand, have them feel the front and back
of their upper arm. Discuss with students what they think is happening.
This will give you their prior knowledge about muscles.
- 32 -
Explore:
Discuss with students the parts of the arm that are causing it to move. Tell
them that the bones cannot move alone, they need a muscle to help them.
Tell students that they will be creating a model of the bicep muscle in the
arm to help them better understand how that muscle helps them move their
arm. Pass out materials to each student group.
Procedure:
 First, students will cut the bendable part off of one straw.
 They will then insert the cut straw into the bendable end of the other
straw. The point where the straw bends represents the hinge joint in
the arm.
 Students should then poke one paper clip into Point A of the straw
structure as shown in the figures below. (If students have difficulty
poking the paper clips through the straws, a pushpin may be used to
poke a hole first.)
 Students will then poke the second paper clip into Point B of the
straw structure as shown in the figures below. These paper clips
represent the tendons that attach the muscles to the bones.
 Once the paper clips have been properly attached, the students will
hook the rubber band onto each of the paper clips as show in the
diagram below. This represents the bicep muscle.
- 33 -
Point B
Point A
Once the students have created their model, they should be able to pull the
rubber band to simulate bicep muscle contraction.
LEP Modifications: LEP students should be paired with another
student to complete this activity so that they can fully understand
the directions and complete the activity successfully.
Explain:
Tell students that the muscles that are attached to and move the bones are
called skeletal muscles. These muscles are attached to bones by a tough
cord called a tendon. Skeletal muscles pull bones to move them. Muscles
do not push bones. The names of the muscles in the upper arm are the
biceps and triceps. Have students flex their arm. Feel the top of the arm.
This is called the bicep. Have students discuss how this is similar to what
they saw happen with their arm model. Now straighten your arm. The
muscle on the other side of the upper arm, the tricep contracts, and your
arm straightens.
Elaborate:
Students can draw conclusions about how other skeletal muscles work to
move other bones. Have students formulate a plan in order to construct a
model of either a hand or leg, using similar materials from the arm model.
This could be done on a separate day.
LEP Modifications: Students will need the support of a partner
and words written on chart paper or the white board if this
activity will be repeated on a separate day.
- 34 -
Evaluate:
Students will retell what helps the bones move. Have them hold a book in
one hand and hold that arm straight out in front of them. Have them put
their other hand on the bicep of that upper arm. Discuss how the muscle
feels, and then have students lift their books up toward their shoulders.
What happens? The muscle shortens and bunches up.
- 35 -
Lesson Eleven: Heart Smart
Objectives:
4.05 Observe and describe how muscles cause the body to move.
LEP Objectives: Students will be able to:
 name the heart muscle and the two actions that make a heart
a muscle.
 trace the path of blood through the body
Essential Question: What are the functions of the heart?
Time: two 30-minute periods
Content Blast:
There are three types of muscles-skeletal muscle, cardiac muscle, and
smooth muscle. We have already discussed skeletal muscles in previous
lesson. The next muscles, cardiac muscles, are found in only one place in
the body - the heart. The heart is a hollow organ made up of four parts, or
chambers. The walls of the heart are made of strong cardiac muscle.
When your cardiac muscle contracts, it squeezes blood out of your heart.
When your cardiac muscle relaxes, your heart fills with more blood.
Materials:
Per Student Group:
timer or watch with a second hand
Per Class:
diagram of the heart
stethoscope (ask your school nurse)
Process Skills: Observe, Communicate, Predict, Measure, Classify, Infer
Engage:
Begin class by wearing the stethoscope. Ask students where they have
seen the instrument before, what is its purpose and how is it used.
Student’s response may be that it is used to listen to our heart by a doctor.
Ask students if any other organs can be heard by the doctor using a
- 36 -
stethoscope. Students should have some background about the heart.
Pose the question to students “Is the heart a muscle?”
Explore:
Show a diagram of the heart. Students will notice it is much different than
what they usually draw to represent a heart. Point out the heart has two
sides, right and left, separated by a thick muscular wall. The heart
contracts and relaxes, so therefore, students should conclude it is a
muscle. When your cardiac muscles contracts, it squeezes blood out of
your heart through the arteries. When your cardiac muscle relaxes, the
veins fill your heart with more blood. Continue to explore by completing
the pulse taking activity.
1. Hold your left hand in front of you with your palm up.
2. Place the first three fingertips of your right hand on the inside of your
left wrist in the groove below the base of the thumb. You may need
to move your hand around slightly before you can feel the pulse.
3. Use the timer to count the number of times your heart beats in one
minute. Record the results.
4. Run in place for about one minute.
5. Repeat steps to take pulse again.
6. Record the results.
Discuss the difference.
Explain:
The heart is a bag of muscle that squeezes itself about once every second,
sending blood flowing throughout the body. When you exercise, your
muscles need more oxygen. To meet this need, your heart will beat faster
to increase blood flow, which supplies the muscles with nutrients and
oxygen. The amount of increase in heart rate depends on the type and
how long a person exercises. Heavy exercise will cause a greater increase
in heart rate than light exercise.
LEP Modifications: Students could benefit from a real life connection
by watching a video which demonstrates how the heart pumps, or
observing the heart action on an interactive website.
- 37 -
Elaborate:
Have students sequence the steps of the blood flow through the heart.
They can write or sketch to show the process. Students can imagine they
are a drop of blood and describe their trip through the heart, out an artery,
and back again through a vein.
LEP Modification: Sequencing through illustration is a great way
for LEP students to be successful in this activity. If students are
expected to write, they will need a word box to help with spelling.
Evaluate:
Ask students why the heart is a muscle and what type of muscle it is.
Students should know it is a muscle because it contracts and relaxes. It is
classified as a cardiac muscle. Have students share their responses to
how blood circulates through the body.
LEP Modification: Novice and Intermediate students will have
difficulty verbalizing or writing their responses, and should be
permitted to trace the route with their fingers or draw it in for their
assessment.
- 38 -
Lesson Twelve: Can We Control It?
Objectives:
4.05 Observe and describe how muscles cause the body to move.
LEP Objectives: Students will be able to respond to questions about
voluntary and involuntary muscles using verbal or non-verbal
communication (e.g. use word card to give answers).
Essential Questions: What are voluntary and involuntary muscles?
Time: one 45-minute period
Content Blast:
Muscles can be classified by how they are controlled. Cardiac and smooth
muscles are involuntary muscles. Smooth muscle makes up the internal
organs. Smooth muscles are not attached to bones. There is smooth
muscle in the stomach and intestines. An involuntary muscle causes
movements you cannot control. Most skeletal muscles are voluntary
muscles. Voluntary muscles cause movements you can control. Some
muscles are both voluntary and involuntary.
Materials:
Per Student:
recording sheet
book
Process Skills: Observe, Communicate, Predict, Measure, Classify, Infer
LEP Modifications: The specialized vocabulary in this lesson
(frown, goose bumps, stomach growling, sneeze, and intestines)
will have to be translated or pre-taught for LEP students to be able
to participate in the lesson.
- 39 -
Engage:
Have students to smile, and then make a frown. Tell them it takes 34
muscles to frown, but only 13 muscles to smile. Discuss with students how
they made those faces. Discuss whether or not they can control muscles.
Explore:
Provide students with the following list of tasks. Ask them to determine if
they can control these tasks.
1.
2.
3.
4.
5.
6.
7.
8.
Stand up
Turn a page in their book
Sneeze
Walk
Get goose bumps on their arms
Raise a hand
Make your blood stop pumping
Make your stomach growl
Students will quickly realize that some tasks they can do and some they
cannot. Discuss the vocabulary words voluntary and involuntary and ask
the students to classify the tasks as one or the other in a T-Chart. Explain
that tasks you can control use voluntary muscles. Explain that tasks we
were not able to do use involuntary muscles. Most skeletal muscles are
voluntary muscles which allow us to easily move our bones. Cardiac
muscles and smooth muscles are mostly involuntary muscles.

LEP Modification: To ensure that LEP students have understood
the specialized vocabulary, they should complete this activity with
a partner.
Explain:
Ask the students to explain why some actions are voluntary and some are
involuntary. The ones the students could do and the ones the students
could not do. Ask the students to name other voluntary and involuntary
actions and add them to the T-Chart.
Elaborate:
Think about all the ways you used muscles in the past half-hour. Record
the information in the chart. Some examples are given. Add more to the
list.

Evaluate:
Make sure students understand how movement is classified. Have them
respond to the following questions in their science notebooks.
 How many different ways did you use your muscles?
 Did you use more voluntary or involuntary muscles?
Students may suggest they used more involuntary muscles because they
use them constantly. This response is an acceptable conclusion.
LEP Modification: For understanding and successful completion of
this assessment, LEP students should work with a partner to
complete this activity. The LEP student and his/her partner may need
more time to finish, and it would be helpful for them to have spelling
support.
- 42 -
Lesson Thirteen: Taking Care of Muscles
Objectives:
4.05 Observe and describe how muscles cause the body to move.
LEP Objectives: Students will be able to create a poster or public
service announcement (PSA) to encourage healthful living by
exercising.
Essential Questions: What makes your muscles ache or get tired?
Time: two 60-minute periods
Content Blast:
A muscle tear occurs when the fibers of a muscle are separated by a
sudden force or stretching. Treatment includes applying wrapped ice and
bandaging. Returning to action too soon may tear the fibers again. A
muscle strain occurs when muscles that have not been exercised for
several weeks are overused. The pain can be relieved by warm baths and
usually is gone within 2-3 days.
Materials:
Per Class:
five tennis balls
books
timers or watches with a second hand
Process Skills: Observe, Communicate, Predict, Measure
Engage:
Ask students what happens when they are outside playing all day long. Do
they ever feel tired? What if they were swimming all day long? Does their
body ache? Have them predict why they think this happens.
Explore:
Have student pairs rotate between each of the following centers to
experience muscle fatigue. The teacher should demonstrate body
positions for each of the activities prior to the students rotating through the
centers. Students should record how they felt after completing each
- 43 -
activity, as well as, the length of time the activity lasted in a data table.
Student pairs should alternate activities and keeping time.
LEP Modification: Before beginning the centers, make sure that the
LEP student knows how to time their partner. In doing the activity,
be sure the LEP student’s partner goes first to demonstrate the
actions so the LEP student understands what to do when it is
his/her turn.
Center #1
Have several tennis balls available. One student sits in the chair and lays
one forearm flat on the table, palm facing upward. They will hold the tennis
ball in the palm of the hand on the table. The other student should time the
activity for their partner. The student performing the activity will close their
hand around the tennis ball and squeeze as hard as they can, then open
their hand. Repeat this action as many times as they can in one minute.
Each time, they should open their hand completely so that the ball rests in
the palm, then close their hand and squeeze the tennis ball. Rest for 30
seconds, and then repeat the exercise. Do this two more times.
Center #2
One student will stand with their back against a wall. They will slide down
until in a seated position and hold this position for one minute. The other
student will keep time for their partner. Rest for 30 seconds and then
repeat twice resting between each trial.
Center #3
One student will stand up with both arms held horizontally to their sides
palms facing up. They should rest a book on each hand. The student will
hold the position for one minute. The other student will keep time for their
partner. Rest for 30 seconds and then repeat twice resting between each
trial.
Center #4
One student will lay flat on their back on the ground. They will raise both of
their feet into the air so that they are perpendicular to their body. They
should hold this position for one minute. The other student will keep time
for their partner. Rest for 30 seconds and then repeat twice resting
between each trial.
- 44 -
Center #5
One student will complete as many sit-ups as possible in one minute. The
other student will keep time for their partner. Rest for 30 seconds and then
repeat twice resting between each trial.
Students should record their information on a chart as they complete each
trial.

Explain:
Your muscles will begin to get tired after you have continuously performed
the same activity. Your performance will slow down because you are tired.
When a muscle contracts over and over, it uses oxygen and nutrients. If it
is used long enough it will begin to run out of oxygen necessary for the
muscle to operate properly. The lack of oxygen will cause the muscle to
feel tired and to slow down. Tell students by exercising that their muscles
will become stronger, bigger and healthier. List some exercises students
do often such as running, biking, soccer, playing on the playground etc.
Other ways to keep muscles healthy is by stretching before or after
exercising, drink plenty of water, eat healthy foods, and never take illegal
drugs.
LEP Modificaton: Ensure that the LEP students understand the
terms oxygen and nutrients. Have a student demonstrate how to do a
stretching exercise.
- 45 -
Elaborate:
Try other repetitive activities to see if the result is the same.
Evaluate:
Have students write a PSA (public service announcement) for the school
that would convince people to take care of the muscles by exercising,
stretching before or after exercising, eating/drinking healthy, and never
taking illegal drugs. Have students make a “safety poster” to go along with
their announcement.
LEP Modification: Students, especially Novice and Intermediate
level, should do this activity with a partner. Spelling support via a
word box on the whiteboard or chart paper would be very helpful.
- 46 -
Lesson Fourteen:
How Fast Are You?
Objective:
4.05 Observe and describe how muscles cause the body to move
LEP Objective: Students will be able to write a short reflection of
the muscular response time.
Essential Question: How can we improve muscular response time to
a stimulus?
Time: one 45-minute period
Content Blast:
A stimulus is an event that triggers a response. Response time can be
improved with practice.
Materials:
Per Student Pairs:
plastic cup
pencil
small binder clip
Process Skills: Observe, Communicate, Predict, Infer
Preparation:
The teacher will need to poke holes in the bottoms of the paper cups that
are large enough for a pencil to easily slide through.
Engage:
Ask students what their parents do when they are driving and they hear a
fire truck. Discuss how we move over to allow the fire truck to pass
through. Discuss how the sound is the stimulus that causes our response
to move.
- 47 -
Explore:
Students will investigate stimulus and response by responding with hand
movements to the stimulus of a dropping cup. Pass out materials to
student pairs.
LEP Modification: Prior to beginning this activity, the teacher
should model it with a student partner. Be sure that the LEP
student has understanding of the terms dominant hand, index
finger, stimulus, and response time.
Procedure:
 One student places the binder clip on the end of the pencil.
 The student will then slide the pencil through the hole in the cup until
the cup touches the clip. The cup should be upside down.
 While the first student holds the cup and pencil, the second student
places their dominant hand flat on the table and tucks the pencil in
between their thumb and index finger.
 The first student releases the cup and the second student tries to pull
their hand away before the cup hits it.
 Repeat this activity five times with the dominant hand. Students will
record whether or not the cup hit their hand in a data table.
 Once the student has conducted five trials with their dominant hand
they will test their other hand five times.
 Repeat entire activity with the students alternating jobs.
Dominant Hand
Hit
Miss
Trial 1
Trial 2
Trial 3
Trial 4
Trial 5
Explain:
Ask the students the following questions:
 Which hand was slower and why?
- 48 -
Other Hand
Hit
Miss
 Did your response time improve over the course of the activity?
 What could you do to increase your response time?
 What would happen if the distance of the cup drop was increased or
decreased?
Elaborate:
Students can repeat the test using their feet and compare the results to the
response times for their hands. Students could also create a plan to test
stimulus and response in another way to see if the results were similar.
Evaluate:
Students will write a reflection in their science notebooks detailing ways to
increase muscular response time.
LEP Modifications: Provide an alternative assessment for LEP
students, for example:
 Let the student physically act out an answer.
 Let the student choose an answer from a picture array.
 Let the student use a single word after referencing a native
language dictionary.
