In this unit pupils:

• are introduced to the concept of energy in the context of fuels as convenient and therefore valuable sources.
• consider the nature and origin of fossil fuels and renewable sources of energy and how their use has implications for the environment.
• consolidate and extend their ideas about energy resources for living things: food for people and sunlight for plants.
• link the energy resources to the role of the Sun as the ultimate source of most of the Earth's energy resources.

In scientific enquiry pupils:

• recognise hazards and take safety precautions.
• decide what variables are relevant and how to control these to make fair comparisons.
• consider the reasons for repeating measurements and observations.
• use the Bunsen burner and thermometers safely and effectively.
• make measurements of volume, mass and temperature.
• investigate the energy resource in foods, controlling relevant variables.

This unit is expected to take approximately 9 hours

• 'spirit burners' and alcohols or a similar range of fuels
• samples of food, eg dry breakfast cereals, crispbread, toast
• unpainted tin lids
• videos and other secondary sources of information on fossil fuels and renewable energy sources
• aluminium 'takeaway' trays or similar for making solar panels
• samples of coal and oil
• solar cell role cards for class debate on issues related to energy use
