Transcript Hot Wheels Cars - Mrs. Kelly Science

Student Objective
• Explain how speed of an object relates to the
energy of that object.
• To identify the 2 different forms of energy
Warm Up
What is energy?
*When BOTH you & your partner have WRITTEN
down your answers, share them with each
other.

Hot Wheel World Record Jump
video clip
• What did you notice about the design of the
ramp?
• How do you think the engineers got the car to do
the jump?
• What did you notice about the track and the car?
• How was the car different from cars you usually
see people drive?
• How were the tracks different from the streets in
your neighborhood?
Explore Activity
As an engineer, how would you build a ramp to get
your Hot Wheels car to go as FAR as it can??
Materials:
Hot Wheels car
Ramp
Meter stick
Observations: (in your notes section)
How did you build a ramp that made your Hot
Wheels car go the farthest?
Observations Discussion:
• What do you think caused the car to go farther?
• Do you think the type/size/shape of car your
group used affected your results??
Question:
• How exactly does a steeper ramp affect the
distance a car travels?
Think: Does double, triple or quadruple the ramp
height mean double, triple & quadruple the distance?
Hypothesis:
Write your hypothesis UNDER the data table on
your worksheet.
Materials:
Hot Wheels Car
3 Textbooks
Meter Stick
Calculator
Procedure:
1. Build a ramp using 1 textbook.
2. Start car at top of ramp & let go (do NOT push). Record distance
traveled from end of ramp.
3. Repeat 2 more times & record distances.
4. Calculate average distance for the 3 trials.
5. Repeat same procedures using 2 textbooks and then 3
textbooks.
6. Create a bar graph of your average distances. Label your units
of measure on the axis.
7. On your own notebook paper, draw a picture that shows your
ramp with 3 books.
