1. In science, ENERGY is the ability to do work and cause change.

2. We need energy to do everything we do in our daily lives. …Reading a book. …Riding a bike. …Even resting needs energy. …Running around the school.

3. Everything that happens in the world involves movement and for something to move, energy is required. If something takes energy in, then it also gives out. Think about it like this: A light bulb can get energy in from the main electricity supply… …and the bulb give energy back out as light and as heat.

4. echanical Energy adiant (Light) Energy hemical Energy eat (Thermal) Energy lectrical Energy uclear Energy

5. …energy of moving objects. …kinetic energy + potential energy in the system Windmill used to make electricity. Paddle used to turn water to move boat. Peddling bicycle to move forward.

6. …Made up of waves called electromagnetic waves …Light, Ultraviolet light, X rays, infrared radiation (heat), radio waves, microwaves, radar

7. … Energy stored in molecules. …Chemical reactions use or release chemical energy

8. … results from the movement of particles and also produces light in some instances. A beaker of hot water has more heat energy than a beaker of cold water because the molecules are moving faster in the hot water.

9. …when an electrical current flows in a circuit to provide energy to an appliance.

10. …is from the nucleus of the atom. Nuclear Fission – splits 1 atom into 2 Nuclear Fusion – combines 2 nuclei to make 1 HEAT from reaction makes STEAM to turn turbine that generates ELECTRICITY

12. Energy can NOT be created OR destroyed – it can only change from one form of energy to another. These changes from one form to another are called Energy Conversions or Energy Transformations.

13. Let’s look at an example: A camper is using a wood fire to heat a pot of water for coffee. The pot has a whistle that lets the camper know when the water boils. Identify the types of energy involved: Chemical Energy from the wood is changed to Heat Energy. Heat Energy is changed to Mechanical Energy as the water boils and changes to steam that makes the whistle vibrate. The whistle changes the Mechanical energy into Radiant energy to sound.
