Energy sources can be used to provide heat, light, or power.

To generate electricity is to produce or make it.

A water reservoir is a large artificial lake used to store water.

A dam is a barrier constructed to hold back water.

A water turbine is a device that is turned by water to generate electricity.

Water as an energy source (non-statutory)

Science

Pupils learn about the properties of the different states of matter (solid, liquid and gas) in terms of the particle model, including gas pressure,. and about changes of state in terms of the particle model

pupils use knowledge of solids, liquids and gases to decide how mixtures might be separated give reasons, based on evidence from comparative and fair tests, demonstrate that changes of state are reversible changes, and explain that some changes result in the formation of new materials, and that this kind of change is not usually reversible, including changes associated with burning

Physical activity and equipment requiring safe use

Use of equipment that may require supervision for safety, e.g. scissors in KS1, needles, paint, knives, cooking.

What is the name given to a wall built across a valley to raise the level of water. 

Which of these energy sources use turbines to generate electricity?  

so they can make the water in the reservoir move 

so they can make the water below the reservoir move

so the water from the reservoir flows down from a height onto the turbines

It is converted to energy in solar panels.

How does moving water help to generate electricity? 

using moving water doesn't add carbon dioxide to the atmosphere

burning fossil fuels doesn't add carbon dioxide to the atmosphere

Decide if the following statement is true or false and select a reason for your answer: 'Using moving water is a more environmentally-friendly way to generate electricity than burning fossil fuels.'

__________ resources are those which are never used up and so do not need to be replaced.    

because fossil fuels have no impact on the environment

because burning fossil fuels damages the planet

because there is a good supply of fossil fuels 

Why are scientists and engineers researching renewable energy sources?

What do solar cells convert into electricity? 

{{}} turbines use moving air to generate electricity.

the remains of living things over millions of years

rocks heated up in volcanoes over millions of years

rocks in the seabed over millions of years

Match each fossil fuel to the state it is in at room temperature.
