We conducted an insulation experiment to measure which insulating material would result in the least wasted heat energy. We put hot water in cups and insulated with different materials in a cardboard box. We used a thermometer to measure the temperature after 1 hour and 2 hours. Some results surprised us and others were predicted in our hypothesis. We only changed the insulation material to ensure there was only one variable and it was a fair test.
The best insulators in order were
- Sawdust
2. Feathers
3. Tin Foil
4. Cotton wool
5. Sponge
6. Fibreglass
7. Cotton scarf
8. Bubble wrap
9. Newspaper
