Makey Makey + Scratch Project 2

Project Title: Use a Makey Makey to Compute Rate with Distance and Time

Project Link: https://scratch.mit.edu/projects/84226302/

Project Description:
How does rate change as time changes? With Makey-Makey and Scratch students will measure the change in rate over your desired distance and record the correct time as the metal ball passes through two maker special switches. One switch is mounted at the top of the track and the other switch is mounted at a measured distance at the bottom of the track. As the metal ball passes through the top switch a timer in Scratch is started and when the ball passes through the bottom switch the timer is stopped and a calculate routine is invoked to calculate rate from time and distance using r = d/t.
