2. Statement of the Problem
How does plastic, cardboard, and metal affect the speed of the car?

3. Project Overview
We are going to test how metal, plastic, and cardboard ramps will affect the speed of a toy car. Then we will see what affects it the most and why.

4. Variables Independent variable: surface
Dependent variable: speed of car measured in seconds per foot
Constant variables: speed of car, weight of car, length of surface, size of wheels, distance from start to finish, angle of ramp, width, and height
Control group: plastic

5. Hypothesis
If the car is on a metal ramp then it will travel faster then it proves that the surface is faster because it is smoother than the others.

6. Materials
One toy car
3 ramps made out of metal, plastic, and cardboard that are 2.5 inches and I meter long
Stopwatch
Camera with video
goggles

7. Procedure Gather all materials needed and safety precautions
Put goggles on
Cut plastic, metal, and plastic so that its 2.5 inches wide and 1 meter long
Set up the ramps at an angle of 30 degrees
Record time it took for each to get to the finish line
Make chart showing time of cars

9. Data/Observations Analyzes

10. Conclusion
We discovered a lot after this experiment. We discovered that metal helped a car go faster but the cardboard made it go slower.

11. Possible Experimental Errors
We think that maybe the floor slowed it down because it crashed with the floor when it got off the ramp.

12. Applications and Recommendations
The car ramps had different textures witch impacted the speed. Next time we might choose better materials to choose from.
