This document provides an overview of different forms of energy including mechanical, heat, light, electricity, and sound energy. It explains key concepts such as the differences between potential and kinetic energy, how heat is related to the movement of atoms, and how light travels and is reflected. Examples are given to illustrate concepts like conduction of heat energy and refraction of light. The document aims to build understanding of different types of energy and the science behind common energy transfers and transformations.

1. All About Energy! Our Focus: Why is energy so important in our lives?

3. What is energy?

5. Heat energy

6. Light energy

7. Electricity

9. Mechanical energy is the energy of motion.

10. Potential energy is stored energy. Objects with potential energy have the ability to move because of earth’s gravity. Pulls objects toward the ground.

14. The movement of atoms(tiny particles) within a substance.

15. Predict!Would fast movement cause an increase or decrease in heat energy? How do you know?

18. When this occurs through direct touching, this is called conduction.

21. Light is made up of the colors in the rainbow and travels in the straight lines. Remember ROY G BIV.Red Orange Yellow Green Blue Indigo Violet

24. Some objects though reflect light rays – the light rays bounce off these objects.

26. Predict: What would happen if the surface was uneven?

28. This is called refraction.

30. “opposites attract, likes repel”

31. The opposites are called positive and negative charges.

33. When these vibrations are felt by our eardrums we hear sound.

34. Sound travels in waves.

35. Sound travels fastest through solids, then liquids, and the slowest through gases.
