Jamie and Adam test the myth that during a hurricane, a straw can have enough kinetic energy to go through a palm tree. The rest of the Mythbuster team attempts to prove the myth that plants and animals are interconnected through unseen psychic forces. Concepts discussed are wind speed, Fujita scale, velocity and mass relationships, kinetic energy, air pressure, barrel length and impulse time, tree trunk density, polygraph results, using baseline data, interpreting data, controlled variables, voltage measurements, false positives, and the repeatability of results.
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.
Gravity (2013) is a stunning movie exploring the potential dangers of space and the physics behind them. This movie captivates the students through dazzling visuals, but the movie guide keeps them focused on analyzing the physics behind the scenes. Having said that, there are very accurate and inaccurate depictions of Newton’s Laws of Motion. But the inaccuracies add to the dramatic tension and advance the storyline of the movie. The movie guide is designed to have the students analyze the physics of the movie scenes, choose which of Newton’s Laws applies, and then describe why it applies or why it is inaccurate. The movie guide does not analyze the plot or emotional arcs during the movie, it just sticks to the physics behind each scene. The movie guide is best used for classes like physics, physical science, or astronomy.
Adam and Jamie test the myth that wearing steel toed boots can actually cause toes to become amputated. This is a great segment showing the importance of safety shoes. Kari, Tory, and Grant test the myth that a person can become airborne with soda bottles strapped to their backs. This myth demonstrates the difficulty of engineering solutions and the application of Newton’s Third Law of Motion. The science topics mentioned include force, pressure, structural rigidity, structural integrity, human skeletal analogs, Newton’s Third Law, equal and opposite reactions, air pressure, thrust, water to air ratios, PSI, space shuttle Challenger disaster, and o ring failure.
