100
Where do we get the energy that our bodies need?
Energy stored in food
100
What is the law of conservation of energy?
Energy cannot be created or destroyed, it can only be transferred or stored in different ways.
100
What is an example of a fossil fuel?
Coal, oil or natural gas.
100

What does it mean by  a renewable resource?

A resource that will never run out and can be replenished in a short time 

100
What does non-renewable mean?
The fuel/resource will run out one day.
200
What are the units for measuring energy?
Joules
200
Name two ways which energy can be transferred.
Any two from: heating, light, sound, electricity, forces.
200

What are fossil fuels made from?

Plants and animals that were trapped in mud and rocks.


200
Name an example of using water to generate electricity.
Any one from: tides, waves, hydroelectricity
200

What environmental problem is being caused by fossil fuels?

Climate change


300

How can you find out how much energy is in a peanut ?

burning it, and seeing how hot it makes a test tube of water


300
How do we describe the way in which energy is stored in food, fuels and batteries?
Chemical energy
300
Is electricity a fuel and why?
No, it has to be generated using other energy resources.
300

Name a resource that will not run out 

Any one from: Hydroelectricity, geothermal energy, wave energy, solar, wind  

300
Describe a way in which you can use less fossil fuels
Any acceptable answer (ex. Walk instead of drive a car, wear a sweater instead of turning on the heater)
400

Suggest why a teenager needs more energy than a 5-year-old child.

The teenager is bigger.

400
How do we describe the way in which energy is stored in moving objects?
Kinetic energy
400
What is a biofuel?
Renewable fuel made from plants or the wastes from animals
400
Name two resources that do not depend on the sun’s energy.
Any two from: Geothermal, tidal, nuclear
400
Name a renewable resource that is not available all the time.
Any one from: Tidal, solar, wind and waves
500

What happens if your food contains less energy than you use? 

If someone uses up more energy than they get from their food they will lose weight

500

What kind of objects might store energy  as gravitational potential energy.

Anything in high position

500
Why are fossil fuels considered non-renewable?
We are using them up faster than they are being formed. Renewable resources are those where the resource is replenished at about the same rate it is being used.
500
How does wind energy originally come from the sun?
The wind is produced as a result of giant currents in the Earth's atmosphere, which are driven by heat energy from the sun.
500
How does burning fossil fuels contribute to climate change?
More carbon dioxide is added to the atmosphere which traps more heat in the atmosphere.
