Sheep & Wool Investigation | Insulation Practical Science Lesson

What do sheep, jumpers and hot water have in common? Wool… and a great science investigation!

This engaging practical lesson introduces students to the properties of wool, focusing on how wool acts as an insulator and why it helps sheep stay warm. Students explore the science behind insulation while developing key practical skills such as collecting data, reading temperature scales and drawing conclusions.

The investigation involves wrapping wool around a beaker of hot water and measuring how quickly the temperature changes over time, before comparing the results with a beaker that has no wool insulation. Students record results, analyse patterns and explain what the data shows about heat loss and insulation.

Alongside the practical, the resource also introduces interesting facts about sheep and explores other properties of wool, including waterproofing and stain resistance.
