Unit
2:
Heat
The Heat unit covers concepts related
to three topics:
Temperature and Heat
Students learn to differentiate between heat and temperature and
practice estimating temperature. Devices that measure temperature,
and how each functions, are introduced. The particle theory is
addressed as the model for the study of heat. Students investigate
changes of state and factors that affect the rate of temperature
change.
Heat Transfer
Conduction, convection, and radiation are investigated and explained
in terms of the particle theory. Students explore the heat capacities
of several materials and relate these characteristics to energy
transfer. The role of heat in weather focuses on convection and
the heat capacity of water.
Producing and Using Heat
Students investigate methods of heat production and discover that
heat is a by-product of most reactions (Law of Conservation of
Energy). The environmental focus includes a look at renewable
energy sources and heat pollution. Several lessons focus on the
topic of home heating in terms of heat transfer, heating methods,
and energy conservation.
