| A | B |
| Echo | When sound is reflected off a surface |
| Transparent | Water and clear plastic wrap are this |
| Radiation | How energy travel from the sun to earth |
| Parallel Circuit | Electricity can flow through more than one path in this |
| Amplitude | The amount of energy in a sound wave |
| Current Electricity | Does not transfer heat |
| Refract | Light does this when it travels through materials like glass |
| Static Electricity | A balloon can stick to a wall because of this |
| Current electricity | The flow of electrical charges through a circuit |
| Prism | it can separate white light into bands of coloured light |
| Gases | Sound travels most quickly through this |
| Conduction | Occurs when energy is transferred between two objects that are touching |
| Concave Lens | Can cause light to bend outward from the center so light rays spread apart |
| Electric Motors | These change electrical energy into mechanical energy |
| Turbine | A set of angled blades attached to a shaft that provides mechanical energy for a generator |
| Fuse Box and Circuit Breaker | Both open a circuit if too much current is flowing |
| referee blowing a whistle | Has a very high pitch |
