9. Thermal Energy

10. What is Thermal Energy? The energy of heat – It transfers from hotter objects to cooler objects

11. Temperature The measure of how hot or how cold something is

12. Conduction

13. What is Conduction? The transfer of heat that occurs when 2 objects of different temperature touch

14. Conductor

15. What is a Conductor? A substance that heat or electricity can easily flow through

16. Insulator

17. What is an Insulator? A material that protects or resists the transfer of heat, electricity or noise

18. Convection

19. The transfer of warm air up and cool air down in a circular motion

20. What do you think is making the warm air rise & the cool air sink?

21. So, what’s more dense…warm air or cool air? Cool air = more denseWarm air = less dense

22. Radiation

23. What is Radiation? The transfer of heat through empty space

24. Identify the following as conduction, convection, or radiation: Heat we feel from the sun

25. Identify the following as conduction, convection, or radiation: The heat you feel when you touch a hot stove

26. Identify the following as conduction, convection, or radiation: Heat you feel when you touch a cup of hot chocolate

27. Identify the following as conduction, convection, or radiation: This is responsible for making macaroni rise and fall in a pot on the stove

28. Identify the following as conduction, convection, or radiation: Heat you feel when you sit around a campfire

30. Chemical Energy Energy that is released during a chemical reaction or change Type of Potential Energy Examples: – Batteries – Burning Wood – Coal – Oil – Eating Food

31. Electrical Energy Energy in the form of electricity Type of Kinetic Energy Examples: – Plugging in a PS3 to the wall

32. Light Energy Energy in the form of electromagnetic waves Type of Kinetic Energy Examples: – A flash light turning on

33. Mechanical Energy Energy of motion Type of Kinetic Energy Examples: – Machines – Batting Cage – Running

34. Thermal Energy Heat energy Type of Kinetic Energy Examples: – Microwave – Stove
