Use the simulation in your science or Physics class to illustrate effect of thermal insulation and heat loss
This simulation helps GCSE Physics students understand the effect of thermal insulation — how different insulating materials slow the rate of heat transfer from a warm object to its cooler surroundings.
A hot box (starting at 100°C) loses heat to the outside environment (fixed at 20°C). Students select from four insulation types — None, Foam, Fibreglass, and Aerogel — and observe in real time how the inside temperature falls at different rates depending on the insulation used.
The cooling curve graph plots temperature against time, allowing students to directly compare how quickly or slowly each material allows heat to escape. Faint reference lines for all other materials remain visible on the graph, making it easy to see the contrast between good and poor insulators side by side.
The simulation is grounded in real physics — it uses Newton’s Law of Cooling (Q/t = kAΔT/d), with accurate thermal conductivity (k) values and realistic insulation thicknesses for each material, so the relative differences between scenarios are physically meaningful.
This supports the following GCSE Physics specification points across AQA, OCR, and Edexcel:
- Thermal insulation reduces the rate of energy transfer between objects at different temperatures
- The rate of heat transfer depends on the thermal conductivity of the material, its thickness, and the temperature difference across it
- Good insulators (low k values) significantly reduce heat loss compared to poor insulators or uninsulated surfaces
- Students should be able to evaluate the effectiveness of different insulating materials
- U-values and insulation are directly linked to reducing energy consumption in homes and buildings
