(Grades 1st-12th) Explore heat transfer, absorption and reflection of heat, phase changes, chemical & physical changes, and thermal conductivity with this hands-o thermal energy kit. Kit contains materials for two hands-on investigations (Ice Melting Blocks and Chemical Heat Packs) and IR temperature gauges.
Ice Melting Blocks Activity: Touch these two black blocks, and one feels cooler. Place an ice cube on each block. One cube completely melts before your eyes, while the other stays frozen! Surprisingly, the “cooler” block melts the ice faster! This discrepant event introduces many concepts, including heat transfer, change of state, and thermal conductivity. Kit contains: 6 black aluminum blocks, 6 high density foam blocks, 12 3″ diameter rings, 6 IR temperature gauges, and instructions
Chemical Heat Pack Activity: This fascinating hands-on experiment utilizes a small (4″ x 3.5″) pouch of supercooled sodium acetate to visually demonstrate crystallization and the subsequent release of latent heat. Includes 12 heat packs, IR temperature gauges, and instruction manual.
