1. Forms of Energy

2. Five Forms of Energy
There are five forms of energy that we’ve discussed so far. Can you name and describe each of them ?
(Refer to your science notes, if needed).
Light energy
Thermal energy
Electrical energy
Mechanical energy
Sound energy

3. Light Energy is…
a form of energy which our eyes can detect

4. Heat/Thermal Energy is…
energy related to the temperature of an object

5. energy that is absorbed or delivered by an electric circuit
Electrical Energy is…
energy that is absorbed or delivered by an electric circuit

6. Mechanical Energy is…
energy of motion or movement

7. Sound Energy is…
energy produced by vibrations

8. Conductors and Insulators
Conductors- allows electricity and heat to flow through
Insulator- does NOT allow electricity and heat to flow through
Which spoon(s) would be an insulator and which would be a conductor? Explain.

9. Draw a T-chart in your notebook and sort the items as conductors or insulators with your neighbor
Metal spoon
Plastic spoon
conductor
insulator
Styrofoam cup
Copper penny
Copper wire
Rubber tires
Metal paperclip
Styrofoam ice chest
Wooden block

10. Create a Venn Diagram in your notebook and compare and contrast conductors and insulators with your neighbor. Let’s see who can include the most facts in their diagram after 5 minutes! GO!
conductors
insulators

11. Force What is force? How is force measured?
Force is a push or pull that can change the position or motion of an object/material
How is force measured?
Force is measure used a spring scale. Force is measure in Newtons (N).
How to use a spring scale (optional video):

12. Force Continued… Balloon Powered Car Lab https://www. youtube
Discuss:
What would have happened if the balloon had more force (bigger balloon)?
What would have happened if the balloon had less force (smaller balloon)?
Does the amount of force applied affect the speed of an object?
