A simple lab to test how the speed of a marble changes as the height/slope of a ramp is increased. As students raise the ramp, they will notice the speed of the marble increases. Students will need to calculate their results, create a distance-time graph to represent their data, and write a conclusion of their results.
Materials needed: marble (or ball), stop watch, ramp (I use Hot Wheels track), meter stick.
Main topics: calculating speed, graphing distance vs. time, interpreting graph an
