Today we learned about good insulators and bad insulators. We now know that a good insulator keeps the heat in (plastic wrap, aluminum foil, ect.) while a bad insulator (a good conductor) lets heat transfer through.
We tested this by putting warm water in a bottle and putting a good insulator (we used wax wrap) around the bottle of warm water.
Then we put the bottle in a bucket of cold water. What was supposed to happen was that the warm water temperature would not change and the cold water temperature would not change if the material we used was a good insulator. Although most of the temperatures dropped we had lot's of fun!
