Energy transfer (radiation) - complete lesson (KS3)

A complete, differentiated lesson based on the Activate 2 (P2.5 ) SOW but can be used for others. This lesson covers the key aspects of infrared radiation, thermal imaging and the use of foil blankets etc. Student understanding is checked with a differentiated question grid challenge (answers included) prior to a simple practical. For the practical hot water bottles with different covers, different coloured cups ice or heat packs can be used. Students will use a thermometer to record the temperature of each object and then judge how much infrared radiation is given off using the back of their hands. An alternative simple prac is included where students monitor the temperature of black and silver cans containing hot water. This is followed by 'stretch questions' associated with the practical and a plenary designed to encourage self reflection within students in regards to their progress against the learning objectives.
