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 Meter Stick ramp3 Textbooks Calculator
Procedure:1.Build a ramp using 2 textbooks. 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 4 textbooks and then 6 textbooks. 6.Create a bar graph of your average distances. Label your units of measure on the axis. 7.Below the bar graph, draw a picture that shows your ramp with 3 books.

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?
