scale testing

Adam and Jamie explore the myth that a renegade airplane propeller shredded the fuselage of another aircraft on a runway. The rest of the team experiments with various ways to start a fire without matches. This myth explores survival tactics for making fire including rubbing two sticks together, using a parabolic lens to focus the sun’s rays, using a bullet to start a fire, igniting steel wool with a battery, and using ice as a solar lens. Scientific concepts include photo analysis, scale testing, mathematical analysis of scale, friction, ignition point, surface area and oxygen availability, concave lens, convex lens, surface irregularities, focal points, electrical energy, and thermal energy.
