There are six aspects of energy here for you to investigate: solar, wind, electrical, mechanical, ultraviolet (UV) and chemical.
All six aspects of energy are very important. They may help us reduce pollution. They may assist in overcoming the greenhouse effect. They may help conserve our oil supplies. They can all help us to act responsibly (eg in a way that does not destroy ecological life cycles and does not deplete natural reserves).
Each investigation also helps with your understanding of the word 'energy'.
Choose two or three investigations from the six aspects of energy below.
Solar energy*
How can energy from the Sun be used to heat water? What things will affect how well the sunlight heats water?
How can this be used to help reduce pollution of the atmosphere and help conserve our oil supplies?
Wind energy**
How can the energy in the wind be used?
How can it help conserve our oil supplies?
How might using wind energy help to reduce the smoke from power stations which pollutes the atmosphere?
Electrical energy**
Why is electrical energy so useful?
What other forms of energy can it be changed into?
Why are battery-powered vehicles considered to be the transport of the future?
Why are these vehicles so expensive at present?
Mechanical energy*
What are the different sorts of mechanical energy?
Where are they useful?
What other forms of energy can mechanical energy be changed into?
Can mechanical energy be stored?
Ultraviolet energy**
What is UV energy and why is it dangerous?
What are some of the ways we can protect ourselves against UV energy?
How can we inform others of our findings?
Chemical energy**
Why is chemical energy so useful to us?
What other forms of energy can be produced from chemical energy?
What are our main sources of chemical energy, and why must we conserve them?
