Friction ? A Hot Topic!?
When you rub your hands together, the action of scraping the surface of your skin back and forth against each other causes ,the molecules in your skin to move a little faster. The faster that molecules move, the higher the temperature. So the friction of rubbing your hands together makes them feel warmer.

Milli?s Insulation Investigation
To keep homes comfortable inside and save energy, insulation is placed in the walls, where it works like a jacket around the house. The most common types of insulation used in homes are fiberglass and cellulose. Fiberglass is extremely fine strands of glass. Cellulose insulation is a pulpy, puffy form of recycled newspapers, boxes, and waste paper. In this activity students test several different materials to find out which one is the best insulator.
