Energy transfer and payback time

A lesson (or potentially 2) focusing on reducing energy loss from domestic situations using forms of insulation. The PPT introduces typical types of insulation and learners then have opportunity to complete differentiated activities in explaining how double glazing, cavity wall and loft insulation etc. reduce heat transfer.

Learners are then introduced to the financial implications of deciding which is “best” and organically arrive at the pay back time equation. There is then a differentiated equation worksheet with markscheme.

The pack of activities includes;

PPT
lesson plan
Types of insulation differentiated activity
Payback time equation differentiated exercises
