2 Statement of the Problem How does plastic, cardboard, and metal affect the speed of the car?
3 Project OverviewWe 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 footConstant variables: speed of car, weight of car, length of surface, size of wheels, distance from start to finish, angle of ramp, width, and heightControl group: plastic
5 HypothesisIf 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 MaterialsOne toy car3 ramps made out of metal, plastic, and cardboard that are 2.5 inches and I meter longStopwatchCamera with videogoggles
7 Procedure Gather all materials needed and safety precautions Put goggles onCut plastic, metal, and plastic so that its 2.5 inches wide and 1 meter longSet up the ramps at an angle of 30 degreesRecord time it took for each to get to the finish lineMake chart showing time of cars
