What are we going to learn about?

Types of Energy and Energy transfers

Starter

Sort out the cards into 4 groups!

Can you tell what each group is?

Timer

Starter

For set 1, the 4 groups are:

• Types of renewable energy: Biogas, Solar, Wave, Wind• Items powered by electricity: TV, Radio, Fridge, Laptop• Items that have energy stored in them: Man, Food,

Petrol, Wood• Things you can do by using your own energy: Hop,

Walk, Run, Cycle

Starter

For set 2, the 4 groups are:

• Types of non-renewable energy: Coal, Gas, Nuclear energy, Oil

• Types of stored energy: Gravitational, Chemical, Nuclear, Elastic

• Energies involved in the Energy transformation for a TV: Electrical, Heat, Sound, Light

• Things you can find a solar panel on: Roof, Calculator, Satellite, Toy car

Y9 - Energy

Today we are going to:

• List the different types of energy• Identify the renewable/non-renewable

sources of energy and how energy can be transferred

• Describe a way to use chemical energy to pump water using scientific vocabulary

Y9 - Energy

By the end of the lesson, you will be able to:

• Name several types of energy and describe them (4)

• Explain how a play pump works and describe the transfer of energy taking place (4/5)

• Present your idea to the class (F) using scientific vocabulary and structure (H) (5/6)
