vehicles?

Sample Inquiry-Based Lesson
Engaging Scenario
You are members of a NASCAR team. This year due to the
high gas prices and reported shortages, the NASCAR
sponsors present a new challenge for the drivers and their
teams. Each team will be given the same materials (bucket)
to construct a vehicle. The winner of this year’s race will be
the vehicle that travels the greatest distance using rubber
band energy rather than fossil fuel.
Fabulous prizes will be awarded to the team that travels the
greatest distance.
Engaging Scenario
Your pit (bucket) contains all the parts you
will need for this investigation. Review your
technical drawing to see how pieces fit
together.
Your design should be based upon the standard
vehicle, but adaptations may be made by your
team.
Focus Question(s)
What design works best to propel the vehicle
forward the greatest distance?
Describe the role of the rubber band as related
to the motion of the vehicle.
Prediction
Write a prediction describing what you think
will happen.
Conditional statements
If_____________ then____________.
OR
I think _________ will happen because
_______________________________.
Planning
Plan what to do to accomplish your task.
Plan how to collect data.
Decide how to organize your data to share with
the whole group.
Data/Observations
Time for the test drive!
Record your data and observations.
Use the chart paper provided so that each team can
share their results.
What have you Learned?
Examine your data. What claims can you make about
the design and motion of your vehicle?
What is your evidence?
Revisit your prediction. Examine the prediction that
you made at the beginning of the lesson. Do you wish
to affirm (keep) or revise your prediction? If you
wish to revise your prediction, do the revision below
the one you first made.
Making meaning
Today I learned ________________,
Next Steps/New Questions
What kind of extensions could apply to the
original question?
What next steps could be taken to further
explore this investigation?

NEWTON’S FIRST LAW
•An object at rest remains at rest and an
object in motion in a straight line, unless
acted on by an outside force
•The more massive the object, the more that
object tends to resist changes in its state of
motion
NEWTON’S FIRST LAW
Forces
A force is a push or a pull.
Force gives an object the energy to move, stop
moving, or change direction.
Balanced Forces
Balanced forces do not cause a change in
motion. They are equal in size and opposite in
direction.
Unbalanced Forces
Unbalanced forces always cause a change
in motion. They are not equal and opposite.
Newton’s Third Law
Forces always come in pairs - known as
"action-reaction force pairs."
Science Content Blast
Energy - the basic ability for
doing work
Potential energy - energy ready to
be released
Kinetic energy - energy of motion
Friction - opposes the vehicle’s
forward motion as it changes the
energy of motion into the energy
of heat

Please disassemble your vehicles and return all
materials to your pit (bucket).
