This unit develops the concept of heat as a form of energy.
Temperature is one of the criteria used to estimate the quantity of heat energy.
The other major component of the unit is the concept of heat transfer, and the application of the principles of heat transfer to energy conservation. The grade 3 Core Unit, Properties of Matter , and Optional Units, Fire and Fuels and Heating and Cooling , all prepare students to deal with the concepts in this unit. Forms of Energy , a grade 4 Core Unit deals with the nature of heat and some of its effects. This unit is intimately related to the grade 5 Core Unit on Resources since it is through the renewable and nonrenewable resources that most of the heat on the Earth is produced. It would be most profitable to integrate these two units.
