The
physics lesson about inclined planes didn't go exactly how it was supposed to, but we learned something AND we used the Home Depot make and take kit.
For example, the plane was supposed to be 2 rulers at differing angles. So, we used the clamps to anchor the half of our original ramp. The cars were not heavy enough to be forced down the ramp by gravity. And finally, our rubber bands were too strong even when we tried several sets (Dollar Store bundle of rubber bands used one more time). So, we tried to weigh the car down with Magnetix. It was not a significant amount of pull until we loaded up one of the cars to stretch the rubber band a whole inch.
