Unique way to illustrate the different heat capacities of various metals features a slanted panel with four grooves to hold four different metals. Place a sheet of bee's wax in the front of the pane and submerge the metal samples in hot water. When the metals are placed on the grooves simultaneously they will melt and sink through to different levels based on their specific heat. Includes four metals cylinders: Aluminum, Copper, Lead and Tin; support stand, two pieces of bees wax and instructions.

The set consists of three rugged, sealed, transparent plastic tubes containing colored fluids of three different viscosities. The bubble in each tube rises at a constant speed which depends on the type of fluid, the angle at which the tube is inclined and to some extent the temperature. Students track the time it takes for an air bubble to move from the bottom to the top of 3 different colored tubes. From this they can link the mathematical concept of slope to the physical science concept of velocity. Includes instructions.
