Mini-Kit ‘Heat’

Investigating Heat, Temperature and Heat Transfer Experimentally

Age: 8–14 years
Materials: for 1 work group or demonstration
Use: Experiments on temperature, evaporation and condensation, thermal radiation, heat conduction, and changes in volume and shape caused by heat

With the Mini-Kit ‘Heat’, students investigate fundamental phenomena of heat through practical experiments. The set is suitable for one work group and can also be used for classroom demonstrations.

The experiments cover the operating principle of a thermometer, evaporation and condensation, thermal radiation and the absorption of thermal radiation. Students can also compare the thermal conductivity of different materials and investigate heat conduction in water.

Further experiments demonstrate how heat affects materials. Students observe the change in volume of air and water vapour during heating and cooling, as well as changes in the shape of different metals when heated.

The equipment includes a thermometer, beaker, Erlenmeyer flask, glass tubes, a bimetallic strip, metal foils, tea lights and a burner.

The picture shows a red plastic case filled with various materials for experiments. These include glasses, test tube plates, chemical equipment and other utensils needed for science lessons.
