"Melting Plastics" Trailer

Cook all kinds of plastics with a hot air gun to see which ones melt, which ones bubble, which ones shrink, and which ones do nothing. This relates to melting point, temperature, freezing point, and convection. This video also includes one of Mr. Mac’s crazy stories, “Jack & Jill in the Land of the Giants,” to help students remember the lesson. Difficulty: Hard.
