Mrs. Wishnowski and the students decided to test out some hypotheses about insulation. They talked about how Arctic animals have insulation and houses have insulation and coffee mugs have insulation. Then we made wonders about what we could use for insulation and tested those out on snow. We wrapped snow in newspaper, foil and salt. We left one ball of snow uninsulated. We made guesses as to which would help insulate the snow from the warm air. Then we watched ... Turns out foil kept the snow from melting best and salt made the snow melt faster.
