Experiment set PRIMARY SCHOOL 4 (Heat and Fire)


Discovering phenomena related to heat

In simple but fascinating experiments, children can learn about good conductors and poor conductors of heat as well as observing the flow of heat from one place to another. They can investigate the different ways white bodies and black bodies respond to heat and find out why heat insulation is needed in buildings.

Introduction to the world of measurement

Spurred by the unreliability of humans’ perception of heat, children go on an experimental search for a practical device and a suitable unit for measuring temperature. They will investigate how liquids, solids and air expand when they are heated and make a scale for a thermometer without any graduations.

Tea candles and a fireproof base

Ordinary tea candles are used to provide the heat. When experimenting with candle flames, a fireproof base of fire prevention category B1 is to be used. This is included in the set.

Using the storage case as a stand

In order to build stands, the case can be turned upside down. In the bottom of the case there is a threaded hole into which a stand rod can be screwed.
