Energy and types
- 1.
- 2. Task- With yourpartner list as many different types of Energy as you can. Paired talk- • I think... • I agree because... • I see your point but what about... • Another idea might be... • Also... • In addition... • To summarise our views then... 2 Min
- 3. What is energy?? Energyis the ability an object has to perform a task. It makes everything happen. It makes machines work. It makes our body to move. Energy is Indestructible!
- 4. TYPES OF ENERGY ELECTRICALENERGY LIGHT ENERGY SOUND ENERGY KINETIC ENERGY THERMAL ENERGY CHEMICAL ENERGY NUCLEAR ENERGY
- 5. ELECTRICAL ENERGY We useELECTRICAL ENERGY everyday. In Light bulls and in things that use batteries.
- 6. LIGHT ENERGY In thingsthat produce light. Things like the Sun, traffic lights and candles give off light.
- 7. SOUND ENERGY Made byvibrations. Eg. Vocal chords, speakers and musical instruments, noisy students (like you!)
- 8. KINETIC ENERGY In movingthings. When we ride a bike we turn chemical energy from the food we eat into kinetic energy.
- 9. THERMAL (HEAT) ENERGY Itproduces heat. The sun produces lots of thermal energy and heats our planet.
- 10. CHEMICAL ENERGY With achemical reactions. EG: food. Our body turns this energy into thermal or kinetic energy.
- 11. NUCLEAR ENERGY Energy isstored in the nucleus of atoms. When the nuclei are joined together or split apart, NUCLEAR ENERGY is released. Eg. nuclear power plants.
- 12. Progress Check- Namethat energy 3. Kinetic Energy 2. Heat Energy 1. Sound Energy 4. Chemical Energy 2 Min
- 13. Task: Watch thevideo clip and try and write down the 9 energy types. ENERGY Challenge- Explain why you think it’s that type of energy.

- 15. ENERGY sound nuclear electrical chemical kinetic heat light Class Discussion-Energy Investigators Challenge-Explain why you think it’s that type 3 Min
- 16. 1. A caris moving (_______ energy) 2. The engine is hot (______ energy) 3. The headlights are on( ______ energy) 4. It is making a lot of noise ( _____ energy). 5. Inside the car battery are chemicals (_________ energy) which store energy. 6. There are lots of wires which pass (__________ energy) to the controls. 7. The car seat is springy (________ energy) 8. If the car is left on a hill without the handbrake on it will roll down because of (______________ energy). KINETIC HEAT LIGHT SOUND CHEMICAL ELECTRICAL ELASTIC GRAVITATIONAL Independent Work-Decide which energy Progress Check- Record your score 3 Min
- 17. Lab Partners- Overto you Challenge- Identify what energy transfers are useful and wasteful For each example observe what happens and try to identify the different energies. What happens to the energy in each example? Answer the two questions for each in your book. 10 Min 2 Mins on each example
- 18. What energy isgoing in? Chemical Energy What energy is coming out? Light Energy Heat Energy How do we show an energy transfer in science?
- 19. What energy isgoing in? How do we show an energy transfer in science? Electrical Energy What energy is coming out? Sound Energy Heat Energy Light Energy
- 20. Electrical Energy What energy isgoing in? What energy is coming out? Sound Energy Heat Energy Light Energy How do we show an energy transfer in science?
- 21. converts Light Energy into Electrical Energy converts ElectricalEnergy into Light and Sound Energy converts Chemical Energy into Kinetic Energy converts Chemical Energy into Kinetic, Sound, Light and Thermal Energy converts Light Energy into Heat Energy converts Electrical Energy into Thermal Energy converts Kinetic Energy into Sound Energy converts Chemical Energy via Electrical Energy into Light Energy
- 22. converts Sound Energy into Electrical Energy converts ChemicalEnergy via Kinetic Energy into Gravitation Potential Energy converts Nuclear Energy into Kinetic, Sound, Light and Thermal Energy converts Electrical Energy into Chemical Energy converts Light Energy into Chemical Energy converts Chemical Energy into Light Energy A glow stick converts Nuclear Energy into Light and Thermal Energy A star converts Kinetic Energy into Sound Energy
- 23. converts Elastic Potential Energy into Kinetic Energy converts KineticEnergy via Elastic Potential Energy into Gravitational Potential Energy converts Gravitation Potential Energy into Kinetic Energy A ball rolling down a slope converts Kinetic Energy into Electrical Energy converts Light Energy into Kinetic Energy converts Chemical Energy via Thermal Energy into Gravitation Potential Energy converts Elastic Potential Energy into Kinetic Energy converts Chemical Energy via Kinetic Energy into Electrical Energy A generator

- 42.
- 43. Non-renewable energy They runout. They pollute.
- 44. It comes fromthe ground or the seabed. We use drills to extract it. Crude oil is processed into petrol. We burn petrol and produce thermal energy. Crude Oil
- 45. It is amixture of gases that we obtain from the ground or seabed using drills. Ww burn it to produce thermal energy. Natural Gas
- 46. It comes fromthe ground. We mine it and burn it to produce thermal energy. Coal
