This lab is designed to have students construct balloons and have them race down fishing line to explore the conversion of potential energy into kinetic energy, Newton’s 2nd and 3rd Laws of Motion, and the equilibrium of forces. The lab is 4 pages long with detailed, easy to follow instructions, that should allow the students to seamlessly complete the lab with little teacher redirection. But in reality, at least with my students, they need to be kept on-task whenever they perform a lab.
Grant, Tory, and Kari test the myth that if you blow your own sail, you can move forward. Adam and Jamie explore the world of movie sounds to test if what you hear in the theaters resembles anything you hear in reality. Scientific principles alluded to include Newton’s First Law of Motion, objects in motion stay in motion, objects at rest remain at rest, Newton’s Second Law of Motion, F = MA, internal forces, external forces, force cancellation, net force, and free body diagrams.
