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)

How dizzy would you get? Part 1
Get into groups of 4 and assign roles
Fill in the gaps on the Play pump worksheet
Work together to explain how it works!

How dizzy would you get? Part 2
Make sure you have defined the role of each person in the group
Work together to come up with a new idea for people in Africa to help them access water more easily!

How dizzy would you get? Feedback
With your group, go around and check other groups’ work
Give them feedback with the post-it notes on:Clarity of descriptionPros and consDiagramEnergy transfer equation
