Adam and Jamie are examining the myth that wrecking balls can be used to make a Newton’s Cradle. Grant, Kari, and Tory are also testing to see whether a bird perched on a teetering car can cause it to fall over the edge. Scientific concepts include energy transfer, Newton’s Third Law, equal and opposite reactions, energy efficiency, surface deformation, elastic and inelastic collisions, potential and kinetic energy, pendulum motion, trophic levels, biology, predator prey relationships, energy flow, food webs, type 1 lever, fulcrum, pivot points, lever arms, and torque.
Adam and Jamie take on a challenge from President Obama: is it possible to set a ship on fire using the power of the sun? Kari, Tory, and Grant see if it is possible to punch a car hard enough to get it to flip over! Science topics include Archimedes, parabolic mirrors, thermal energy, ignition points, reflectivity, light rays, aiming sights, levers, fulcrum, type 1 lever, pivot point, lever arms, torque, speed, mass, center of gravity, momentum, W = FD, and forward linear momentum.
