Take out Lab worksheet where you wrote your hypothesis yesterday.

2. How exactly does a steeper ramp affect the distance a car travels?
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.

3. Materials: Procedure: Hot Wheels Car Meter Stick ramp
3 Textbooks Calculator
Procedure:
Build a ramp using 2 textbooks.
Start car at top of ramp & let go (do NOT push). Record distance traveled from end of ramp.
Repeat 2 more times & record distances.
Calculate average distance for the 3 trials.
Repeat same procedures using 4 textbooks and then 6 textbooks.
Create a bar graph of your average distances. Label your units of measure on the axis.
Below the bar graph, draw a picture that shows your ramp with 3 books.

4. BrainPop – “Forms of Energy”
Lab Conclusions:
How exactly does a steeper ramp affect the distance a car travels?
Does double, triple or quadruple the ramp height mean double, triple & quadruple the distance?
WHY??
Students should see that the distance traveled is increasing, but the amount of increase incrementally decreases with each book.
