Duration: 10 days
Summary
Students will be guided though the next levels of organization by studying
tissues, organs and organ systems.
Clear Learning Targets
“I can”…statements
____ identify various tissues in plants and animals.
____ show that multicellular living things are organized in levels by cells, tissues, organs
and organ systems.
____ make comparisons between the organ systems of plants and animals.
____ explain how the processes of the human body stay in balance through
homeostasis.
____ defend an organ of the body to prove its necessity to the overall function of the
body.
Activity Highlights and Suggested Timeframe
Days 1
Engagement: By conducting the class lab of placing celery and broccoli in
colored water, students will observe how the vascular tissue of a plant transports
materials through the plant stalks.
Day 2
Exploration: Students will use the textbook to explore the various levels of
organization of living things, focusing on tissues. They will also add the tissue section
to the Levels of Organization Foldable began in Life Science Unit One.
Days 3-4
Explanation: Students will use a flower to explain how a body system is composed
of organs that work together to carry out a particular function.

LESSON PLAN
NEW LEARNING STANDARDS:
*The content statements for sixth-grade life science are each partial components of a larger concept. The parts have been isolated
in the New Learning Standards to call attention to the depth of knowledge required to build to one of biology’s important
foundational theories: Modern Cell Theory. It is recommended that the content statements be combined and taught as a whole. As
a result, the sixth-grade life science New Learning Standards are being presented in the CCS curriculum arranged by their
relevance to the levels of organization of living things.
6.LS.1- Cells are the fundamental unit of life.
 Different body tissues and organs are made of different kinds of cells.
Note 2: Emphasis should be placed on the function and coordination of these components
6.LS. 4- Living systems at all levels of organization demonstrate the complementary nature of structure and
function.
 The level of organization within organisms includes cells, tissues, organs, organ systems and whole
organisms.
 Whether the organism is single-celled or multicellular, all of its parts function as a whole to perform
the tasks necessary for the survival of the organism.
 Organisms have diverse body plans, symmetry and internal structures that contribute
SCIENTIFIC INQUIRY and APPLICATION PRACTICES:
During the years of grades K-12, all students must use the following scientific inquiry and application practices with appropriate
laboratory safety techniques to construct their knowledge and understanding in all science content areas:
Asking questions (for science) and defining problems (for engineering) that guide scientific
investigations
 Developing descriptions, models, explanations and predictions.
 Planning and carrying out investigations
 Constructing explanations (for science) and designing solutions (for engineering)that conclude
scientific investigations
 Engaging in argument from evidence
 Obtaining, evaluating, and communicating scientific procedures and explanations
*These practices are a combination of ODE Science Inquiry and Application and Frame-work for K-12

COMMON
MISCONCEPTIONS

Growth is not a prerequisite of life.
Students confuse cells and molecules and atoms. Cells are made of
molecules, which are made of atoms.
Students may think that cells are the components of nonliving things,
including carbohydrates and proteins.
Strategies to address misconceptions:
1. Show diagrams of levels of organization beginning with the atom.
2. Explain how cells contain nonliving things like carbohydrates and proteins.
Lower-level: For the evaluation students may want to be grouped or special
consideration given when assigning organs to insure that challenged students
are given a body organ that is easy to research.
DIFFERENTIATION
Higher-Level: During the evaluation phase Advanced students or students
finishing ahead of others can be pushed to find organs which fall into one or
more of the following categories and justify their positions:
 Voluntary Separation (organ transplant) e.g. a kidney choosing to
leave to go work for another body.
 Outsourcing (organ function replaced by outside party/machine)
e.g. kidney by dialysis, lungs by ventilator.
 Neglect of duty (function not imperative to body) e.g. appendix.

Period _________________________________
1. How are multi-cellular organisms organized?
The levels of organization in the human body consist of cells, tissues, organs, and
organ systems.
2. What is a cell?
A cell is the basic unit of structure and function in a living thing.
3. What are three major structures of a cell and what do they do?
The three major structures of a cell are the cell membrane, the nucleus, and the
cytoplasm. The cell membrane forms the outside boundary of the cell. The nucleus
directs the cell’s activities and contains the information that determines the cell’s
form and function. The cytoplasm contains the organelles.
4. What do cells do?
Cells carry on the processes that keep organisms alive, release energy, grow, and
reproduce.
5. What is a tissue?
Tissue is a group of similar cells that perform the same function.
6. What are the four types of tissue and what do they do?
The muscle tissue allows for movement. Nervous tissue enables you to see, hear,
see, and think.
7. Compare tissues to the structures of a cell.
Tissues are like the structures of a cell because they perform a specific task
contributing to the overall benefit of the organism. For example, the epithelial tissue
is like the cell membrane, it separates the outside from the inside.
8. What is an organ?
An organ is a structure that is composed of different kinds of tissue and performs a
specific job.
9. How is an organ similar to a tissue?
Organs perform a specific job.
10. How are organs like cells?
Organs are made up of different parts (tissues) that work together like cells are
made of structures that work together.

11. What is an organ system?
An organ system is a group of organs that work together to perform a major
function.
12. What are the major organ systems of the human body and what do they do?
The circulatory system transports materials to and from cells. The endocrine system
controls many body processes by means of chemicals. The muscular system
enables movement. The digestive system breaks down food and absorbs nutrients.
The nervous system detects information from the environment. The skeletal system
supports and protects the body. The respiratory system takes in and eliminates
carbon dioxide. The excretory system removes waste.
13. How is the human body like a cell?
It has organ systems like the structures of the cell that function together to take
care of the bodies needs. For example, the endocrine system is like nucleus
controlling the body by means of chemicals, the circulatory system transports
materials to where they are needed, the digestive system breaks down food an
absorbs nutrients like similar organelles, etc.

Flower Diagram and Dissection
Materials:
Flower diagram sheet

One flower blossom for each pair of students
Toothpick
Ruler
Hand lens
Teacher only: X-acto knife and cutting board
Students are usually surprised that organisms other than animal reproduce sexually since they assume that the
term sexual reproduction is interchangeable with any term meaning sexual intercourse. When teaching about
the organs and organ systems, having students diagram and dissect a flower is a good way to introduce them
to the idea that animals and plants have analogous organs for carrying out similar functions. Most sixth-graders
will be unaware that flowers have male and female parts as well as male and female reproductive cells.
Step one: flower diagram
Have students complete the flower diagram. It is suggested that each part of the flower be colored in such a
way that each part of the flower stands out from the others.
Step Two: flower dissection
Alstroemeria is probably the easiest flower for students to dissect because they are fairly simple and closely
resemble the classic flower diagram. Alstroemeria is also inexpensive and readily available throughout the year
at grocery chains such as Kroger.
Give each individual or pair of students a complete blossom. Have students observe the flower and identify as
many parts as they can, using the flower diagram as a guide. Have them complete two to three of each of the
qualitative and quantitative observations while the flower is still intact.
Students should draw, label and measure the outer petals after having gently pulled them off the blossom. The
evidence of the sepal in an alstroemeria is the green tip on the larger petals.
Repeat the above process with the smaller inner petals and then the stamens. Students should be careful
handling the stamens because the anthers will separate easily from the filaments and can be hard to find once
that fall away.
Finally, when it is time to dissect the pistil, you should go to each desk and split it lengthwise with an X-acto
knife. Draw label and measure like before. Using toothpicks, students should be able to extract the ovules from
the ovary. Counting these makes a great quantitative observation.

Human Body Corporation Cutbacks
The human body is comprised of multiple systems (11 total; Prentice Hall Life Science tackles
8). In this lesson students will each take the role of an organ working for the Human Body
Corporation.
The Setup:
Unfortunately, times being what they are, the company must make some cutbacks. Students
will receive a letter from the CEO explaining the cutbacks and that they must come to a
board meeting prepared to defend their position. Organs without a solid justification for their
continuance with the company could be cut.
Students need to be assigned the role of a body organ. This can be done on notecards or
by writing the names of the assigned organs on the form letters to be handed out explaining
the cutbacks.
Explain that each student is to learn the function of their organ and write a persuasive letter
to the board stating why the job performed by the organ is imperative to the body as a
whole and how other organs depend on this organ for their success. Students with organs in
the same system may want to appeal to the board as a group but will each need to submit
individual letters.
You may want students to form the board of directors or other adults could be brought in.
Students should read their letters and be told that decisions on final cuts will be made after
all appeals have been submitted.
An abundance of resources with information on organ function can be found at the
following WebQuests which were the inspiration for this lesson:
http://wilson.cr.k12.ia.us/miller/webquest.htm
http://hrsbstaff.ednet.ns.ca/kmason/human_body_webquest.htm
A rubric for the science portion of this lesson follows the suggested organ list.
Columbus City Schools
Curriculum Leadership and Development
Science Department June 2013
A few things to keep in mind:
1. This project is easily adapted for a group. Check the referenced WebQuests.
2. Advanced students or students finishing ahead of others can be pushed to find organs which
fall into one or more of the following categories and justify their positions:
 Voluntary Separation (organ transplant) e.g. a kidney choosing to leave to go work for
another body.
 Outsourcing (organ function replaced by outside party/machine) e.g. kidney by dialysis,
lungs by ventilator.
 Neglect of duty (function not imperative to body) e.g. appendix.
3. It is suggested this be a cross-curricular assignment between the science and language arts
classes. Students can use the writing portfolio persuasive writing rubric as a guide for the
writing conventions when composing their letters to the board of directors.
4. You may want students to submit a resume for their organs when presenting to the board. The
resume would allow students to lay out their information in a more graphic way and give them

Dear ______________, Faithful Employee of the Human Body Corporation:
As you know, the Human Body Corporation (HBC) has experienced many challenges over the past several years and we
recently announced a restructuring plan which has been designed to position HBC for long-term success and operational
efficiency.
We continually review every aspect of our systems’ operations to ensure we remain competitive and are able to sustain
our long-term business objectives. As a part of our restructuring, each system is obligated to cut costs where possible for
the success of the reorganization of HBC. Regrettably, reducing costs requires that we must make a number of tough
decisions. Several of these very difficult decisions involve modifying the body structure so as to allow HBC to share
certain work across the HBC system, which will result in a reduction in force. We will also be forced to outsource jobs to
companies outside of HBC. Unfortunately, the reality is that our employee population will be affected by the steps we
must take.
In order to decide which employees will be eliminated, the Executive Board of HBC will allow each employee to plead
his/her case in front of the Board of Directors. It is recognized that you are part of a department and that you may feel
your department as a whole can make a more persuasive argument, but ultimately, you are viewed as an individual and
you alone are responsible for defending your position.
We are making an attempt to mitigate, or lessen, the number of employees who may experience an employment loss as a
result of this reduction in force by offering voluntary separation options. An employee who can show that although his
function is not required by HBC, but may be crucial to another similar corporation, may be offered an exit package to
ensure a smooth transition into a new place of employment.
Of course, here at HBC, we encourage all employees to support each other, but at times it may be imperative to report
another employee’s neglect of duty. In addition, if you are aware of an outsourcing opportunity that HBC is not currently
taking advantage of, please bring these cost effective alternatives to our board. Bonuses may be issued for proof of any
employee whose job is no longer crucial to HBC.
Good luck – the company’s future “health” depends on you!
Sincerely,
Fonda Cells, CEO

Common Student Misconceptions about Cells and other Living Things
1. If it moves, it is alive.
Many things that move aren’t alive, such as cars, clouds, and flowing water. The living things that are most
familiar to children are likely to be animals that move. Since they consider animals to be alive, they may
associate the characteristic of movement with life.
2. If it seems to move by itself, it’s alive; if it’s moved by something else, it’s not alive.
A shadow moves by itself, but it’s not alive. Fire also moves by itself. Once children recognize that there are
non-living things that can be moved by an external force — like clouds moved by the wind, or a bicycle
pedaled by a person, they may make the finer distinction that something is alive only if it can move itself.
3. If it makes light or a noise, it’s alive.
A burning candle and a flashlight make light but are not alive. A ringing bell and a piano make noise, but
are not alive. Younger children may believe this because they associate “doing something” with being alive.
4. It’s not alive unless it’s “doing something.”
A potato doesn’t appear to be doing anything, yet a potato is alive. If you plant a potato in a suitable
environment, it will grow into a potato plant. At the cell level, all living things are constantly “doing something,”
even if this can’t be detected. Children may hold this idea because they connect life with activity, particularly
movement. In contrast, familiar examples of nonliving things — like rocks or books — don’t demonstrate activity.
5. To be alive, something has to “breathe.”
Not all living things “breathe” in the same way that animals do — inhaling and exhaling. Plants, for
example, do not breathe. However, the cells of all living things do take in and release gases. Children’s
firsthand experience of the need to breathe and their observations of other animals may lead them to think
that all living things have to breathe. The process where plants take in CO2 and release O2 during
photosynthesis is sometimes likened to breathing, so children may equate it with breathing.
6. Growth is not a pre-requisite of life.
One characteristic of life is a life span, which includes a period of growth. From a living beginning as a
single cell, all life forms can be observed to grow — even organisms that are made of only one cell. Growth
occurs as cells get bigger and, in multicellular organisms, as cells divide to form new cells. This idea may arise
because children observe some living things when they are no longer growing. A full-grown plant, for example,
may not appear to grow.
7. Objects like seeds, spores, eggs, and pupae are not alive, but they can give rise to living things.
Because seeds, spores, eggs, and pupae appear to be “doing nothing,” many children think they’re dead
or nonliving while at the same time believing that they can give rise to living things. Just as all cells come from
an existing cell, all life comes from something that is alive — there is no “discontinuity” of life during a life span.
Seeds, spores, eggs, and pupae represent the living beginnings of a life span and have the potential for
growth, development, reproduction, and death. They also demonstrate the other characteristics of life. This
makes them alive. Children may believe this because they do not observe any activity in these objects, and
they can’t see the developing organism inside.

8. Plants and fungi are not alive.
Because plants and fungi don’t move, some children think they aren’t alive. Nonetheless, both plants and
fungi demonstrate the characteristics of life. They are built from cells, have life spans, require matter and
energy, respond to their environment, and carry the hereditary material DNA. Children who consider
movement as a requirement for life may hold this idea. In this case animals may be considered to be the only
things that are alive.
9. Plants have a different kind of life than animals.
Plants and animals differ in many ways. However, the characteristics of life apply equally to both groups
of organisms. Each is made of cells, has a life span, uses matter and energy, responds to its environment, and
carries the hereditary material DNA. Children may think this because the observable differences between
plants and animals seem to make them “opposites” of each other. This also may be reinforced by placing the
emphasis on differences while teaching about these groups of organisms.
10. Cells are static structures.
Cells are dynamic hotbeds of metabolic activity.
11. Cells are resting when they are not dividing.
Cells are most metabolically active during interphase, the period between cell divisions. They are
typically engaged in biosynthesis and growth during this time.
12. Respiration occurs in the lungs and is solely the process of gas exchange.
Respiration has two stages - gas exchange which occurs in lungs, gills, or stomata, and biochemical
changes that occur in the cells (cellular respiration).
13. Cellular respiration is characteristic of animal cells but not plant cells. Plant cells photosynthesize instead.
All eukaryotic cells capture energy from the breakdown of sugars via cellular respiration in the
mitochondria.
14. Plant and animal cells obtain their nutrients (food) from the environment.
Plant cells have the unique capacity to synthesize their own nutrient building blocks, 6-carbon sugar
molecules, from inorganic substances such as CO2 and H2O. All other organisms and their cells must take in
organic molecules derived directly or indirectly from plants.
15. Everything a cell needs gets into it by diffusion.
Only the smallest molecules such as H2O, CO2, and O2 can diffuse freely into and out of cells. Larger
more charged molecules such as sugar and salt ions require active transport across the membrane.
