"Heat Conduction Liquid Crystals" Trailer
Students experiment with a material that changes colors when the temperature changes, trying different kinds of insulation to see which ones will block the heat source. This relates to heat conduction, specific heat, colors, interference of light waves, electricity, the chemistry of liquid crystals, and properties of insulators. This video also includes one of Mr. Mac’s crazy stories, “Jack & Jill’s Missing Heat Shield,” to help students remember the lesson. Difficulty: Hard. (The liquid crystal film is hard to find.)
Here's a short Preview of the lesson.
