In The Laws of Motion: Hovercrafts, students will learn how to make and use models to investigate the principles behind the laws of motion. As they test and refine their project, students -- and viewers -- are encouraged to make predictions based on experimental evidence as they learn to calculate the effect of forces on the motion of objects. The concepts of Newtonian mechanics are investigated by using clear demonstrations and graphics, and students discover how technological advancements are built on scientific knowledge. Part of the multivolume Science Lab Investigations! DVD Series. Includes a Teacher's Guide.
