What type of insulation, doors and windows will help a home maintain its temperature? Students will learn about R-value, specific heat, convection and conduction as it relates to insulating a home. Students will then use a mock economy to purchase insulation and insulate a "paper box" house. The houses will then be placed over a light bulbs for a class period and the temperatures will be measured inside and out. Students will use a spreadsheet to determine the cost of the insulation to preserve a degree of temperature.
