Additional Ideas for Developing Investigations and Learning Experiences and Suggested Extensions to Learning in Technology/Engineering are in Appendix III.
Please note: For grades 6-high school, there are suggested learning activities after each set of learning standards. The numbers in parentheses after each activity refer to the related technology/engineering learning standard(s).
Energy and Power Technologies-Thermal Systems
Broad Concept: Thermal systems involve transfer of energy through conduction, convection, and radiation, and are used to control the environment.
|4.1 ||Differentiate among conduction, convection, and radiation in a thermal system, e.g., heating and cooling a house, cooking.|
|4.2 ||Give examples of how conduction, convection, and radiation are used in the selection of materials, e.g., home and vehicle thermostat designs, circuit breakers.|
|4.3 ||Identify the differences between open and closed thermal systems, e.g., humidity control systems, heating systems, cooling systems.|
|4.4 ||Explain how environmental conditions influence heating and cooling of buildings and automobiles.|
|4.5 ||Identify and explain the tools, controls, and properties of materials used in a thermal system, e.g., thermostats, R Values, thermal conductivity, temperature sensors.|
Suggested Learning Activities
- Create a model to test the concept of conduction and compute heat losses, e.g., through the multi-layer wall of a building. (4.1, 4.2, 4.4)
- Design and build a hot water solar energy system consisting of a collector, hoses, pump (optional), and storage tank. After it has been heated, calculate the heat gains achieved through solar heating. (4.1, 4.5)
- Design and build a model to test heat losses through various materials and plot the results. (4.2, 4.5)
- Design and build a solar cooker for various food substances. Each student should design their solar cooker for her or his specific food. (4.1, 4.2)
- Design an awning for a business based upon the seasonal changes in the angle of the sun. (4.2)
