Students research energy and materials that went into their items. Ask students to use the Internet, library or other sources to gather more specific information regarding the natural resources used in the production of their items. Students should research all the materials and energy that went into making their items and decide whether these came from renewable or nonrenewable natural resources. A skateboard might have a plastic board derived from petroleum, metal wheel supports from minerals or metals in the earth, and rubber wheels from tree sap. In addition, nonrenewable fossil fuels, such as oil, gas or coal were used to process raw materials to manufacture and transport the skateboard.
Students create visual representations of their favorite items.
Distribute poster board and markers. Have students use the information they have researched to create visual representations of their favorite items. Presentations should include the materials, resources and energy which went into the manufacture and transport of the items. Reflect, summarize and discuss. When students have completed their presentation, ask them to explain them to the class.
