Geography KS3/4: Wasting energy
A number of experts help the families identify areas where they can reduce energy.
Dr. Alan Owen, an energy and sustainability expert, uses a thermal imaging camera to show how poorly insulated homes can lose lots of energy, by the process of convection which allows warm air to escape.
Energy monitors and fitted to all the homes to allow the residents and experts to track their usage.
Energy expert Lucy Conway discusses energy rating labels for appliances and the cost of running household items.
The final expert Colin Tonks, shows the residents how much energy is needed to boil one cup of water in a kettle using pedal power.
Twelve people pedal for seven minutes to boil just one cup of water, as an indication of how much energy they are regularly wasting.
These ideas are used to try and encourage the families to cut their overall energy usage and bills within three weeks.

This could be used to support energy calculations.
Students could apply their numeracy skills to work out the overall household cost of some household appliances, checking their answers on the clip when they've finished.
This could be extended in a mini project to find out the cost of running other appliances around their home or school.
This clip will be relevant for teaching Geography at KS3 and GCSE in England and National 4/5 in Scotland. Appears in OCR, Edexcel, AQA, WJEC in England and Wales, CCEA GCSE in Northern Ireland and SQA.
