Unit Abstract

In this unit students investigate energy transfer in homes which are constructed using different material and designs. The emphasis is on heat transfer and practical ways to prevent energy loss in homes and other buildings. Students are organized into teams to identify common characteristics and shapes of dwellings and how surface area and volume are related to actual living space. Then they investigate the relationship between the heating and cooling of a building and the impact of insulation and material types on the heat energy transfer between the building and its surroundings. Students also investigate the insulating properties of various materials by designing experiments to measure temperature change of hot and cold objects at various time intervals. Next they explore where insulation should be placed in a building to increase energy efficiency and factors that constrain the amount of insulation that can be used. Students explore the connection between the placement and size of windows, overhangs, and awnings with heating and cooling costs. This analysis is then expanded to include the effect of the sun’s altitude in the sky during different seasons. The unit concludes by students experimenting to determine the final temperature when two liquids of different temperatures are mixed and when a hot metal object is added to a container of cold water, which leads to the concepts of specific heat of materials, heat energy conservation, and entropy.
