Heat

OVERVIEW:

(taken from the “Ontario Curriculum Document”):

Heat energy plays a critical role in natural processes and in human life. Global warming has also focused considerable attention on the processes that control temperatures at the earth’s surface. By acquiring a working understanding of the nature of heat, students in Grade 7 will gain new insights into the ways that heat affects our world. Students will learn about the causes and effects of heat, investigate its properties, relate it to geological and meteorological processes, and use their newfound knowledge to design a device to maximize or minimize heat transfer. They will also use the particle theory to help them explain their observations.

BIG IDEAS:

(taken from the “Ontario Curriculum Document”):

  1. Heat is a form of energy that can be transformed and transferred. These processes can be explained using the particle theory of matter.
  2. There are many sources of heat.
  3. Heat has both positive and negative effects on the environment.

STUDENT LEARNING GOALS:


GOAL #1: I can explain how heating and cooling are important in everyday natural and artificial processes.

GOAL #2: I can explain the difference between temperature and heat.

GOAL #3: I can use the particle theory to explain heating/cooling and expansion/contraction.

GOAL #4: I can describe the different methods of heat transfer (convection, conduction and radiation) and how these can drive natural processes.

GOAL #5: I can determine ways in which we can conserve energy by effectively controlling energy transfer.

GOAL #6: I can identify a variety of different types of energy and different sources of energy and list the advantages and disadvantages to using conventional and alternative energy sources.

GOAL #7: I can explain how the human production of greenhouse gases is causing changes in global climate.
