This two-day lab introduces students to the concept of density and how it is different than mass. Students will obtain the mass and volume of specific objects and learn how to calculate density first-hand. They will also make a liquid density column to demonstrate the density of various liquids and where objects will settle in them.
The Mythbusters are testing a story from World War 2, which says that airman Staff Sargent Alan Magee survived a 22,000-foot fall by crashing through a train station at precisely the time a bomb went off. Kari, Grant, and Tory also test whether or not money is saved when turning off lights when you are not in a room. Science topics discussed are terminal velocity, vectors, fluid friction, density, shock waves, electricity, power conservation, steady state usage, power consumption, LED, CFL, fluorescent tube, incandescent bulb, halogen, and bulb longevity.
The Mythbusters test the ancient myth that the Chinese put a man into space in the 15th century. Jamie and Adam also attempt to verify if there is anything as free energy. Grant, Kari, and Tory investigate whether a spinning ceiling fan can act as a decapitation machine. Science topics include the Law of Conservation of Energy, structural integrity, Newton’s Third Law of Motion, equal and opposite reactions, thrust, forces, flight stability, thrust vectoring, exhaust gas pressure, perpetual motion machines, phase changes, density, internal and external energy sources, center of mass, animal and human analogs, and rotational inertia. The episode can be found on either of the following DVD sets (they are identical).
