After taking a look at our study guides this week, there was a misconception that students still had about inclined planes, so we did an experiment to sort things out!
You can see in the picture below, where students made predictions about what they thought would have a greater speed rolling down the ramp. (Research shows that if students predict and write their prediction down, they will retain more information.) We conducted our tests and found the speed of each object on two different heights of inclined planes. The results speak for themselves!
