This is a great lab to begin the exploration of the world of forces on objects! The lab consists of 5 worksheets that conceptually guide the student through the exploration of forces, unbalanced forces, net forces, static and dynamic equilibrium, friction, Newton’s Laws of Motion, and acceleration.
Adam and Jamie explore the myth that a penny thrown off the Empire State Building can kill someone. They also explore microwave myths concerning cooking your organs from too much tanning and investigate the myth of exploding water in the microwave. Finally, they examine the possibility that Lucille Ball was able to pick up radio signals through her dental fillings. Scientific concepts discussed include terminal velocity, wind tunnel testing, updrafts, net forces, air resistance, drag, mass, acceleration, impact forces, radio waves, microwaves, ultraviolet waves, water impurities, distilled water, boiling point, super-heated water, Faraday cages, point contact diode, and electrical current generation.
Adam and Jamie test various means that spies use to escape their pursuers in the movies. These include the testing of road spikes, oil slicks, and smoke screens. Kari, Grant, and Tory fire a soccer ball out of the back of a moving truck to try and create the illusion that it falls straight down. This is relative motion at its finest! Scientific concepts include low pressure zones, low frictional coefficients, vector addition, net forces, vector cancellation, zero net forces, relative motion, energy cancellation, and calibration testing.
