Teacher View Section 1: Temperature and Energy
This series of booklets looks at the concept of energy in one particular context – the flow of energy between objects that are at different temperatures. The reason for doing this is to develop and practise a consistent way of talking energy that will be used later in a wider variety of contexts. The focus is on thinking about where energy is stored and how it passes from one object to another.

The first booklet (Mixing) looks at how temperature can be thought of as a concentration of energy. This idea is used to explain how energy flows from hot objects to cold objects (Difference and flow) and how energy is dissipated when it passes into the surroundings (Spreading out). These ideas are then applied in a variety of everyday contexts (Heating and cooling), before being extended to consider the role of insulation as a barrier to energy flow (Insulation).

Booklet 01
This booklet uses parallel animation and practical work to begin to develop a powerful analogy for thinking about energy, energy transfer and temperature.

Booklet 02
Difference and Flow
The model used in the first booklet is developed and applied to consider the importance of temperature difference in driving energy transfer between bodies.

Booklet 03
Spreading Out
In transfer, or spread, of energy from a small object at higher temperature to surroundings at lower temperature, the relative sizes of object and surroundings matters, and from animation and practical observations of this come introductory ideas about conservation and dissipation.

Booklet 04
Heating and Cooling
This builds on the model established and used in the first three booklets, and places the ideas in everyday contexts. It also goes further, by considering objects that are initially cooler than their surroundings as well as those that are warmer.

Booklet 05
Everyday examples, as well as use of arrows to indicate energy transfer as introduced in earlier booklets, provide the starting points for observations of the passive effect of insulation.
