A. Waves involve a transfer of energy without a transfer of matter.
B. Water and sound waves transfer energy through a material.
C. Light waves can travel through a vacuum and through matter.
D. The Law of Conservation of Energy: Energy is conserved as it transfers from one object to another and from one form to another.

Project
The goal of this project is to build a roller coaster for marbles using foam pipe insulation and to investigate how much of the gravitational potential energy of a marble at the starting point is converted to the kinetic energy of the marble at various points along the track.
Type: Project
Teaching Idea
In this hands-on and web interactive project, students design and build a machine inspired by animals where the entire structure flips or jumps (vertically or horizontally) using basic materials such as sticks and rubber bands. The students will explore concepts including power amplification, elastic potential energy, and kinetic energy by manipulating physical objects.
