1. The document discusses the six main types of energy: thermal, heat, solar, chemical, electrical, and mechanical. 2. It provides examples and explanations of each type of energy, including how thermal energy is the motion of particles, heat transfers thermal energy, solar energy comes from the sun, chemical energy is stored in particles, electrical energy flows in circuits, and mechanical energy can be kinetic or potential. 3. Interactive elements like questions and diagrams are included to help explain and reinforce the concepts.

2. Energy
SC Standard 6-5.1
Energy is the ability to cause change in an object.
• The change can involve either the motion or the
position of an object or its particles.
• Energy can exist in many different forms.
forms
•We will focus on five types of energy this year.

Can you guess what kind of energy each picture represents?

3. Thermal Energy
SC Standard 6-5.1
- All matter is made up of particles too small to be seen.
These particles are always moving.
- Thermal energy is the energy of the motion of these
particles. Since all matter has particles that move, all
matter has thermal energy.

4. Heat Energy

Heat Energy (continued)
- As heat is added to a substance, the particles move
faster and the temperature goes up.
- The faster the particles move, the higher the
temperature.
