Overview (AB Ed): The production, transfer and transformation of heat energy plays an important role in meeting human needs. In learning about heat, students investigate sources and uses of heat energy and consider the impact of resource usage on our long-term ability to meet energy needs. In focusing their studies, students explore different applications, investigate the scientific principles involved and consider questions about the nature of heat. The particle model of matter is introduced to help students explain their observations and understand relationships between heat and temperature.
Focusing Questions (AB Ed): What heat-related technologies do we use to meet human needs? Upon what scientific principles are these technologies based? What implications do these technologies have for sustainable use of resources?
