| | | | | |  | | Why do we need to try so hard to stay at the right temperature? In order to survive and be comfortable in hot or cold environments, humans (and all animals) need to control the amount of heat energy they gain or lose. To understand this process more fully, it is important to understand the concepts and interrelationship of heat, temperature and thermal equilibrium.
This unit uses the idea of ‘flow’ into and out of a system, making an analogy with the movement of water, to help explain what thermal equilibrium means. In a series of maths and science lessons, pupils use applets and simple experiments to build their knowledge and understanding of these key concepts. These ideas are then applied to the prevention of hypothermia in a case study.
