Unit Plan Title
Suggested Time Frame
One-Dimensional Motion
2 weeks
Overview / Rationale
The One-Dimensional Motion Unit focuses on one of the major purposes of physics in studying
the motion of objects. Everything in the world moves, even if it seems stationary due to the
Earth’s rotation. Kinematics will be introduced to the student with basic concepts of motion.
The basic physics of motion in which an object moves along a single axis (one-dimensional
motion) will be analyzed in depth and will be the foundation in studying vectors and motion in
two and three dimensions. This unit will introduce students to the concept motion and the forces
that cause it. The motion of an object can be described by its position and velocity as functions
of time and by its average speed and average acceleration during intervals of time. It will
investigate this motion using both graphical and mathematical methods and will look at scenarios
with and without acceleration. They will be able to distinguish between distance and
displacement as well as speed and velocity. Through demonstration, experimentation, and
calculations students will be able to explain different aspects of an object’s motion. Several
professional fields, including geology, medicine, and sports, utilize the topics that will be studied
within this unit.
Science Common Core Standards 2009
5.1 Science Practices: All students will understand that science is both a body of knowledge
and an evidence-based, model-building enterprise that continually extends, refines, and
revises knowledge. The four Science Practices strands encompass the knowledge and
reasoning skills that students must acquire to be proficient in science.
5.2 Physical Science: All students will understand that physical science principles,
including fundamental ideas about matter, energy, and motion, are powerful conceptual
tools for making sense of phenomena in physical, living, and Earth systems science.
E. Forces and Motion: It takes energy to change the motion of objects. The energy change is
understood in terms of forces.
5.2.12.E.1 Compare the calculated and measured speed, average speed, and acceleration of an
object in motion, and account for differences that may exist between calculated and measured
values.

2) Performance Task:
Building and racing rules for the Mousetrap Car Project.
Directions:
In addition to building and “racing” a mousetrap car, you will be required to understand the
physics of your car by taking measurements and calculating your car’s efficiency.
Building and racing your mousetrap car:
Only one standard (5 x 10 cm) mousetrap may be used. To ensure that everyone has the same
power source, the mousetrap must be bought for the 55 cents provided by your teacher. The trap
must remain intact; the spring and the release mechanism cannot be modified or moved from the
wood base of the mousetrap. Screws and nails, for example, can be used to attach the
mousetrap to the car, but wood cannot be cut or removed from the base. No launching ramps are
allowed; all parts of the vehicle must move forward as a whole. The only energy source allowed
at the start of the race is that which is stored in the mousetrap spring. You may not hold the
vehicle during release or push the vehicle.
“Coasting velocity”: Using the equation velocity = distance / time, find the velocity of your
vehicle in m/s when the car is coasting after the force from the lever is expended.
Honors Performance Task:
The honors students will also complete a “to-scale diagram” of the car and a reflective essay.

Suggested Time Frame
Vectors in Two-Dimensional Motion
2 weeks
Overview / Rationale
The focus of the Vectors and Motion in Two-Dimensions Unit is to introduce the student to
vectors, a mathematical language of physics to describe quantities. This special navigational
language is the common speech of many practices in our society. This unit takes a deeper look
into the concept of motion by studying motion in two dimensions. Students will investigate this
motion using both graphical and mathematical methods and will look at scenarios with and
without acceleration. They will also be able to look as velocity and displacement as vector
quantities and they will be able to combine vectors as well as split them into components. The
concepts in this unit are the premise of rotation.
Science Common Core Standards 2009
5.1 Science Practices: All students will understand that science is both a body of knowledge
and an evidence-based, model-building enterprise that continually extends, refines, and
revises knowledge. The four Science Practices strands encompass the knowledge and
reasoning skills that students must acquire to be proficient in science.
5.2 Physical Science: All students will understand that physical science principles,
including fundamental ideas about matter, energy, and motion, are powerful conceptual
tools for making sense of phenomena in physical, living, and Earth systems science.
E. Forces and Motion: It takes energy to change the motion of objects. The energy change is
understood in terms of forces.
5.2.12.E.1 Compare the calculated and measured speed, average speed, and acceleration of an
object in motion, and account for differences that may exist between calculated and measured
values.

Essential Questions
How are vectors and scalars used and why are they important?
How are the horizontal and vertical velocities of a projectile related?
How can two people get different measurements for the same objects velocity?
Enduring Understandings
A vector is a quantity having direction as well as magnitude, and is used to determine the
position of one point in space relative to another. Vectors and scalars are used in many
areas other than physics, including medicine, sports, and everyday life.
The horizontal and vertical velocities of a projectile are separate components and do not
directly affect one another.
Measuring the velocity of an object is relative and depends on the frame of reference of
the observer.

Overview / Rationale
The focus of the Motion Unit is to introduce students to the concept of motion. The motion of
an object can be described by its position and velocity as functions of time and by its average
speed and average acceleration during intervals of time. The laws of Newtonian mechanics will
be studied, as well as its applications in everyday life. Students will learn about friction, the
force of gravity and the normal force. They will discover the concept of net force and how to
calculate it and they will apply this concept to a variety of situations and problems. Through
various calculations, students will be able to explain different aspects of an object’s motion.

Unit Plan Title
Suggested Time Frame
Work and Energy
2 weeks
Overview / Rationale
The focus of the Work and Energy Unit is to study the energy transformations and forces that
cause motion in the world we live in. Through the use of machines, work can be made easier
and its energy can be measured and calculated. During demonstration and experimentation,
students will understand the relationship between work, power and energy and it’s applications
in energy conservation. Students will investigate how energy transfers are similar to a system
that requires both inputs and outputs.
Science Common Core Standards 2009
5.1 Science Practices: All students will understand that science is both a body of knowledge
and an evidence-based, model-building enterprise that continually extends, refines, and
revises knowledge. The four Science Practices strands encompass the knowledge and
reasoning skills that students must acquire to be proficient in science.
5.2 Physical Science: All students will understand that physical science principles,
including fundamental ideas about matter, energy, and motion, are powerful conceptual
tools for making sense of phenomena in physical, living, and Earth systems science.
D. Energy Transfer and Conservation: The conservation of energy can be demonstrated by
keeping track of familiar forms of energy as they are transferred from one object to another.
5.2.12.D.1 The potential energy of an object on Earth’s surface is increased when the object’s
position is changed from one closer to Earth’s surface to one farther from Earth’s surface.

2) Performance Task:
In this contest you will build a roller coaster which will keep a steel ball moving for as long as
possible.
Your coaster will be constructed out of only the materials you purchase. Your coaster must fit
inside a cubic meter (i.e., it cannot be larger than a meter in any dimension). The ball must exit
your coaster for it to count. You will be given two runs with time in between to adjust your
coaster. Only the best run will count.
Neither the coaster nor the marble can be aided by an outside force after the initial release. The
coaster may be attached to your blue lab table surface. The marble must be placed on the track
and not pushed or thrown. The coaster can apply force to the marble on its own.
Your score will be based on the total time for ball release until it exits the coaster. You will be
given 10 seconds bonus time for any point where the ball is deemed to be upside down (i.e.
complete a 360º circle in the vertical direction). You total time will be divided by the cost of
your coaster, best ratio wins.
In your lab report you should report the time of each run and whether it was successful or not.
You should also report whether your coaster qualified for any bonus points.
Your conclusion should include how successful you think your machine was and any
41
improvements you think you could have made. You should also mention what specific things
your coaster did to lengthen the ball’s “ride time” and reduce the cost.
Honors Performance Task:
Same as above but include a scale drawing of your coaster and the potential energy your ball
started with as well as the theoretical speed it should have left the coaster with (ignoring friction
and air resistance) in your lab report.

Suggested Time Frame
Momentum
1.5 weeks
Overview / Rationale
In this unit, students will analyze momentum and collisions between two or more objects. They
will consider mass and velocity of one or more objects and the conservation of momentum and
energy. Collisions and other transfers of momentum occur frequently in everyday life, such as
motions of human bodies against each other in contact sports. The different types of collisions
and how to tell them apart based on both observations and also mathematically will be studied.
The unit will culminate by looking at the force of impact, what affects it and how to calculate it.

Circular Motion
2 weeks
Overview / Rationale
Students will study what happens when an objects motion makes a circular path. They will
investigate the effect of the radius of this path on the objects motion and from there develop an
understanding of centripetal acceleration and centripetal force. The difference between
centripetal and centrifugal force and also the effect of the objects inertia on its motion will be
examined. This unit will conclude with an introduction of torque and its application to simple
machines.

Day 2:
What is Heat
and how does
it transfer
energy
between
objects?
Heat and Energy PowerPoint
Anticipatory Set: The coldest and
warmest temperatures recorded in the
US were -80 F and 136 F. What are
these temps in Celsius and Kelvin?
Introduce heat and go over some
examples related to energy conservation.
If 505 kg of water falls over Niagara
Falls (h = 57 m) and comes rest in the
river at the bottom, how much energy
goes into increasing the temperature of
the water and the sound of the crashing
water?

*A 500 kg car is going 30 m/s before the
driver applies the brakes for 5 seconds.
The car’s speed after the brakes are
applied is 15 m/s. How much energy is
lost? Where did it go?
Mount Everest is the world’s highest
mountain. Its height is 8848 m. Suppose
a steel alpine hook were to slowly slide
off the summit of Everest and fall all the
way to the base of the mountain. If 20.0
percent of the hook’s mechanical energy
is absorbed by the hook as internal
energy, calculate the energy gained by
the hook (0.5 kg)

Day 3:
Specific Heat PowerPoint
Why do
some
substances
heat up and
cool down
faster than
others and
how can we
quantify this
effect?
Lab: uses temperature probe, metal
slugs, calorimeter and beaker.
Closure: An Ice cube at 0.0 oC is placed
in a refrigerator that is at 5 oC. You
place your hand (32 oC) in 37 oC water.
In which case is the transfer rate of heat
higher?
Anticipatory Set: To raise 0.25 Kg of
water by 0.2 C you need 209.3 J of
energy. How fast must a 0.25 Kg
baseball travel in order for it to hit the
water and cause this change?
Discus lab with students and then have
them complete it.
Go over Specific heat and the
calorimeter equation and then have
students try these example:
A 2 Kg Iron bar is heated to 86oC and
placed in .25 kg of water at 22 oC. What
is the final temperature of the system?
(Cp for Gold is 129 J/kgoC)

*Indicates Honors level differentiation
Electronic copies of all notes, labs, handouts, assignments, etc. are located on the science
folder on the H: drive. All hard copies are located in the master binder in the science prep
room.
Suggestions on how to differentiate in this unit:
Provide hands-on labs with format skeletons to groups of students.
Facilitate group discussions to assess understanding among varying ability levels of students.
Provide more opportunities for advanced students.
Draw and label diagrams to represent some of the data for visual learners.
Provide choice to students for group selections and roles in the group.
Provide modeling, where possible.
Provide real-life or cross-curricular connections to the material.
Provide time for revision of work when students show need.
