Lesson 10: Electricity review & energy types Objectives: Review circuits, magnetism, electricity Types energy Transfer between types of energy
Review • Draw examples of series and parallel circuits. Label all symbols • What are the symbols for amps and voltage? How are they measured? What do they mean? How do they change in each type of circuit? • What do magnets have around them? How do we know this? What does it look like? • How do you make a magnet? • Why did some of the electromagnets over heat? How could you prevent this? Why do you need to use insulated wire? A iron nail instead of steel? • Which metals are good conductors? Why? What is resistance? How does it affect a circuit?
10.1a What is energy? Energy makes things happen!
ENERGY IN ACTION KINETIC ENERGY ELECTRICAL ENERGY SOUND ENERGY LIGHT ENERGY
STORED ENERGY GRAVITATIONAL POTENTIAL ENERGY CHEMICAL ENERGY HEAT/ THERMAL ENERGY ELASTIC ENERGY
10.1a What is energy? All living things need energy to... live reproduce grow
10.1a What is energy? All living things get their energy from food.Food has a store of energy called chemical energy. Fuels like coal, charcoal, gas, oil, diesel and petrol also have stores of chemical energy.
10.1a What is energy? Energy is needed foreverything we do
Make a table in your notebook: • Fill in the table as you move through the centres.
10.1a Traffic light cards We can use energy even if we are asleep Yes Basic body functions (breathing, heartpumping) use energy
10.1a Traffic light cards All energy is stored energy No Chemical energy is often a store butkinetic, heat and light energy arealmost never stores of energy
10.1a Traffic light cards All living things need energy Yes All living things need energy
10.1a Traffic light cards Stored energy is changed into only one form No Our candle used chemical (stored) energyand produced heat and light energy
10.1a Traffic light cards Is electricity a form of energy? Yes Electricity has electrical energy which moves energy from one place (e.g. a battery)to another (e.g. a torch bulb)
