  • Conductometer with Wax
    Conductometer with Wax.

    Heat transfers by conduction and materials differ in conductivity. This device demonstrates the diverse thermal conductivity of five distinct metals. Place small amounts of the included wax over each metal spoke. Heat the central hub over a Bunsen burner flame and watch the differing rates at which the wax melts. Includes: brass hub; five labeled metal spokes (aluminum, brass, steel, nickel and copper); wax; wood handle; instructions. You need...

  • Accent Investigating Energy
    Accent: Investigating Energy.

    Study heat and light with the simplest of materials - a black can, a silver or white can and a connecting copper bar. Measure the temperature inside dark and shiny bright cans to determine the different ways light and heat are absorbed and radiated. Fill both cans with water - one with hot, one with cold - and connect them with the included energy transfer bar. Observe how the temperature of the water changes.

  • Calorimeter, Aneroid (Dry)
    Calorimeter, Aneroid (Dry).

    Isn't it time to change the calorimeter experiment? Introducing a "dry" calorimeter design that's five times more sensitive than traditional versions. The one-pound core keeps heat loss to a minimum, allowing precise measurements of changes in temperature. Includes: Die-cut styrofoam insulation; aluminum core; machined hole for insertion of thermometer and instructions. You need a thermometer and specimens, such as our 612-1332.
