Big Ideas
- The amount of potential energy something has depends on its position and its mass
- There are many different forms of energy: electrical, light, thermal, sound, chemical, solar and nuclear are some
- Chemical, nuclear, and solar energy can be changed into electrical energy
- The total amount of energy in a system is always the same; energy cannot be created or destroyed
- There are many different kinds of waves: light, sound, mechanical, infrared, x-ray, radio, microwave, and ultraviolet are some
- Energy from the sun is used to produce almost all the food on Earth
- Smooth surfaces reflect light better than rough surfaces
- A rough, dark surface absorbs most light
