Last updated: 18 October 2026
Key Features
Black and white surfaces mounted on a base stand.
Shows the effect of colour on heat absorption.
Works in sunlight or with an external heat source.
A thermometer can be added to measure the temperature difference.

How It Is Used
Set the model in sunlight or in front of a heat source so both surfaces get equal exposure. Students compare how quickly each one warms, ideally reading a thermometer, and relate the result to everyday choices such as light-coloured clothing and building design.
Frequently Asked Questions
Which surface heats up faster on the Heat Absorption Model?
The darker surface absorbs more heat than the lighter one, so it warms faster under the same exposure.
Does the Heat Absorption Model need electricity?
No. It is used in natural sunlight or with an external heat source.
