Practical: Thermal Insulation and Cooling | GCSE Physics
Investigate how different materials affect the rate of energy transfer by heating.
How does a lid reduce energy loss?
What is Practical: Thermal Insulation and Cooling | GCSE Physics?
"An investigation into the effectiveness of different materials at reducing thermal transfer."
Which law states that energy cannot be created or destroyed?
Why can efficiency never be 100% in a mechanical system?
A 5 kg weight is lifted 2 metres. Calculate its GPE (g = 9.8).
Which formula is used to calculate kinetic energy?
Cooling Practical
IV: Type of insulation material (or thickness).
DV: Temperature change over a set time.
CV: Initial volume of water, initial temperature, container shape.
A slower drop in temperature indicates a better insulator.
Practical Point: Use a lid on the container to prevent energy loss by evaporation (a key control variable).

The fastest way to improve your grade is to practise exam-style questions, identify your gaps, and focus only on what you don't know.
