O B MeasureMelt™ Thermal Conductors Test various materials to find the best conductor to transfer thermal energy. Start by defining and discussing the material of each block (4"L x 4"W x 1/2" thick)—steel, foam, plastic, and rubber. Then hypothesize which will make ice melt the fastest and why. Set of 4 includes 1 of each block type. Class Set includes 4 of each, plus lesson direction adaptable for grades K-3 and 4-8. Recommended for
24 beanbags, and lesson direction. Advanced Kit replaces beam with 56’L nylon slackline. Ratchet to two solid objects for safety. Full lists online. Recommended for Elementary and up.
