This straight-forward physics lab activity has students constructing an accurate model of an object’s flight path as it is pulled down by gravity. This is a relatively simple lab to construct and the students can get a hands-on understanding of the physics behind falling objects. This lab also allows the students to predict and model how far an object will fall 7 seconds into the future! A rubric and short answer questions follow the model construction.
The Mythbuster team investigates the claim that with just a few household parts, anyone can make a device that floats above the ground (a hovercraft). Adam and Jamie explore the myth that by jumping up at the last second, you can survive a catastrophic elevator fall. Science concepts include relative motion, pull of gravity, falling bodies, free fall, air pressure, center of gravity, acceleration due to gravity, friction, and drag. The following DVD sets are identical. They both contain the episode.
