1. Energy & Heat Transfer Energy is the ability to create change in a system. There are four main types of energy: Solar Motion Height Heat

2. Solar Energy Energy released by the sun The sun is the main source of all energy on Earth.

3. Kinetic Energy Kinetic energy is also called motion energy. Kinetic energy is energy from motion

4. Potential Energy Potential energy is also called height energy. Potential energy is energy that is stored. An example is rolling a boulder down a hill

5. Heat Energy Heat energy is the energy that heat produces and allows heat to move from warmer objects to cooler objects. Heat energy is to blame when you burn your finger on a hot dinner plate. The heat from the plate moves to your cool hand. OUCH!

6. Friction Heat energy that is released when two objects rub together. The more friction between objects, the more energy that builds up.

7. Heat Transfer Without our sun, there would be no heat. Without heat from the sun there would be no energy. Heat and energy are connected to one another. Heat transfer is energy transferred from a hotter object to a cooler one.

8. The 3 types of heat transfer Conduction Convection Radiation

9. Conduction Conduction is the direct transfer of heat from one substance to another. When it is too hot to walk on the beach barefoot, it is because of conduction.

10. Convection Convection is the transfer of heat by the movement of a fluid ***Convection moves in a circular motion*** Convection is responsible for evaporation

11. Radiation Radiation is the direct transfer of energy by electromagnetic waves An example is how the sun heats the Earth.

12. Conduction, Convection, Radiation

13. Label & define: Conduction, Convection & Radiation

14. States of Matter Solid: Particles are tightly packed. Particles in a solid can vibrate, but cannot move past one another. Solids retain their shapes. Liquid: Particles in a liquid are close together with no regular pattern. Particles in a liquid can flow past one another. Particles in a liquid take on the shape of their container. Gas: Particles in a gas are separated with no regular shape. Particles in a gas vibrate and move freely at high speeds. Gases take on the shape of their containers.
