Rangers of the Earth: Energy Diagrams
From the Rangers of the Earth program: Although the Conceptual Encounter, “Munchline Monitors,” deals with the flow of sunlight energy directly, the next activity in the training builds on the use of indirect sunlight energy introduced in “The Energy Story.” This time the participants analyse their use of fossil fuels at home. However, in the introductory letter, the Rangers urge them to continue examining their use of
sunlight in their food energy too.
Energy Diagrams
Time:
45 minutes for floor plan demonstrations and explanation, initial diagrams and assignment 20-30 minutes to count plugs and discuss impact
Materials:
newsprint (for demonstration)
graph paper
“sun stickers” (connectors, activators, monitors, flames)
1. Read the Ranger letter, then, working in front of the participants, draw on a piece of newsprint a rough floor plan of your own home. Make a list of all the items in a particular room that use energy in any form. Identify these items on the floor plan by placing yellow “sun stickers” in the appropriate places.
sunlight connectors (plugs)
sunlight monitors (space heating or cooling)
sunlight activators (switches)
sunlight flames (cooking or heating water)
(Our “sun stickers” remind us of the various ways we use old sunlight in our lives.)
