3.  Energy is the ability to do work or cause change.  It can be transferred from one object to another.  Potential Energy is stored energy, or “energy of position”  Kinetic Energy is the energy of motion. Think about the roller coaster. It has both types of energy.

4. Lesson 1 Energy conservation and conversion Six different types of energy: pg.447-451 Mechanical = kinetic + potential Sound - results from vibration of particles Electromagnetic - transmitted as EM waves Chemical - stored in chemical bonds Thermal/Heat - due to motion of molecules Nuclear - comes from atom’s nucleus

5. Lesson 1 Energy conservation and conversion Energy Transformation- when energy changes from one form to another. Law of Conservation of Energy- states that energy cannot be created or destroyed, but can change forms. Efficiency- the ratio of useful output energy to input energy. Vocabulary: pg. 454

6. Lesson 1 Energy conservation and conversion Examples of different types of energy: Mechanical: moving car Sound: hearing a car Electromagnetic: x-rays Chemical: food Thermal: heat Nuclear: sun generating energy

7. Lesson 1 Energy conservation and conversion Examples….in your own words! Write an example of energy transformation. Write an example of the law of conservation of energy Write an example of efficiency.

11. Lesson 2 Temperature Vocabulary Kinetic theory of matter- states that all particles that make up matter are constantly in motion. Temperature- a measure of the amount of kinetic energy of the particles in an object. Degrees- equally spaced units between two points Thermometer- instrument used to measure temperature.

12. Lesson 2 Temperature Particles of a solid vibrate in position and are close together Particles of a liquid slide past each other and tumble over each other Particles of a gas move quickly and are far apart States of matter

13. Lesson 2 Temperature Temperature Scales Celsius- Most commonly used around the world and in science Fahrenheit- Used in US and developed in 1700s Kelvin- Used by physicists and units are “kelvins”. Developed in 20 th century

14. Lesson 2 Temperature C=(F-32)5/9 F=C(9/5) + 32 K=C + 273.15

15. What am I?

16. Lesson 2 Temperature How is temperature related to kinetic energy?

18. Lesson 3 Thermal Energy and Heat Thermal Energy- total kinetic energy of all particles in a substance. Heat - the energy transferred from an object at a higher temperature to an object at a lower temperature. Vocabulary

19. Lesson 3 Thermal Energy and Heat How is thermal energy different from temperature? Temp= average kinetic energy Thermal= total kinetic energy more molecules = more thermal energy

20. Lesson 3 Thermal Energy and Heat HOTtoCOLD

21. Lesson 3 Thermal Energy and Heat Vocabulary Calorie - amount of energy needed to raise the temperature of 1g of water by 1  C. This is one way to measure heat. Conduction - transfer of energy as heat from one substance to another through direct contact.

22. Lesson 3 Thermal Energy and Heat Vocabulary Conductor - A material that transfers heat very well. Metals are an example. Insulator - Materials that are poor conductors of heat. Examples include wood, paper, plastic foam

23. Lesson 3 Thermal Energy and Heat Vocabulary Convection - The transfer of energy as heat by the movement of a liquid or gas. Occurs when cooler, denser matter replaces a warmer, less dense mass by pushing it upward. Radiation- The transfer of energy by EM waves.
