In this science experiment we will create insulation. Heat is in constant motion. It flows from warmer areas to
colder areas until it is equally distributed. Insulation provides a barrier to keep the heat from escaping. Lets do
the insulating innovation experiment.
- Half-full cup of sand
- Very warm water
- Small resealable plastic bag
- Large resealable plastic bag
- Aluminum foil
- Face or dish towels
Process Insulating Innovation Experiment
1. Add the warm water to the cup untiil the water just covers the sand.
2. Use the thermometer to take the temperature of the sand.
3. Carefully place the cup inside the small resealable bag and seal the bag.
4. Choose a material that you think will keep the sand warm (newspaper, aluminum foil, or towel).
5. Wrap the small bag with the material and carefully put the whole bundle in the large resealable bag. Seal
6. Wait 15 minutes and take the temperature of the sand again.
7. Repeat the experiment with each of the other two materials.
8. Which material keeps the sand the warmest?
The Science Behind The Insulating Innovation Experiment
You've created insulation! Heat is in constant motion. It flows from warmer areas to colder areas until it is
equally distributed. Insulation provides a barrier to keep the heat from escaping. Two types of insulation are
commonly used. The cloth towels and newspapers provide bulk insulation. Bulk insulation works by trapping
pockets of still air. These air pockets provide a barrier against the heat flow. The aluminum foil provides
reflective insulation. Reflective insulation works by reflecting heat away from its highly reflective surface and
back to it's source. Now grab some friends and do the insulating innovation experiment.
