Forms of energy

1. Forms of energy 4th Grade Science

2. Energy • Energy is the ability to work or cause change. • Work means moving an object form one place to another. • Energy makes things happen. • It can make matter move or change.

3. Mechanical Energy • Mechanical energy is the energy of moving objects. • Examples: moving your body, riding a bike, gears moving in machines

4. Light • Light is energy that we can see. • Light energy comes from the sun. • The sun, burning candle, lightbulb, and match give of energy in the form of light.

5. Heat • Heat is energy moving from matter with a higher temperature to matter with a lower temperature. • Heat also travels to Earth from the sun. • Many things give off heat including wood burning, your body, and light bulbs. • Most things that give off heat also give off light.

6. Sound • Sound is energy that we can hear. • Sound is made by objects vibrating. • Sound energy moves through the air in waves. • When sound reaches your ears, the air in your ear vibrates. This makes your parts of your ear vibrate causing you to hear the sound.

7. Vibrate • Vibrate means to move back and forth very fast. • All the sounds we hear are from vibrations.

8. Chemical Energy • Chemical energy is energy that is stored in a material. • We use a lot of chemical energy by burning things such as coal, oil, and wood. • Our body burns the chemical energy store in food to keep us alive. • Batteries also store chemical energy.

9. Electrical Energy • Electrical energy is the energy of moving electric charges. • Electrical energy moves from power plants through wires to our homes and schools. • Electrical energy runs things such as lamps, refrigerators, computers, and toasters. • Lightning is also a form of electrical energy.

10. Energy Transformations • Energy transformations are the changes from one form of energy to another. • Electrical energy can be changed into heat, light, sound, and mechanical energy. • Chemical energy can be changed into light, heat, mechanical, and electrical energy.

11. Energy Powerpoint • This powerpoint was created using Microsoft Office 2007. All designs, slides, pictures, fonts, and clipart where gathered from Microsoft Office 2007. • This powerpoint was created to go along with Lesson 18 of Tennessee TCAP Coach book, but could be used for any 4th grade lesson on energy.
