CONTENT TOPIC: Environmental Education
CONCEPT: Energy is often wasted in the home and community.
CONTENT OBJECTIVE: 3I2.00 To understand how energy is wasted and how it can be conserved
INSTRUCTIONAL OBJECTIVES: The learner will:
TN COMPONENT OF SCIENCE:
BENCHMARK: Science provides a basis for addressing issues that affect our lives..
It is our responsibility to use our natural resources wisely. Why is that important? (some cannot be replenished)
Conserve means to save. Conserving energy will determine our future supply of coal, gas, oil, etc. (Brainstorm ways you can conserve energy - Turn off unnecessary appliances, etc.)
Let's think about four points related to conservation. They are:
2. Some examples of wasted energy would be: unnecessary use of cars, televisions, motor bikes, excessive use of hot water, thermostats turned to extremes in summer and winter, leaving lights on in unused rooms, etc.
3. There are ways to conserve energy. Insulation is one of these. The concept of insulation is that by adding layers, items or places can be kept cool or warm. Proper insulation helps to keep heat in and cold out, or insulation can keep the cool in and the hot out. Examples of the concept are thermos bottles, styrofoam cups or glasses, hot pads, etc. These materials are used to keep heat or cold from moving from one place to another. The material blocks the flow of heat. This same concept is used to insulate attics and walls in buildings. Among the materials that could be insulators are asbestos, cork, gypsum, paper, foam, etc.
Make a chart that shows which materials used did the best job insulating. Compare and discuss.
2. (Make a survey of your school/home and list all energy users. Make charts to show which energy users use the most energy and ways to cut down on the energy wasted.)
3. (Invite a resource person from a local utility system to discuss ways of conserving energy at home and at school.)
