Give each group a copy of the Resource Clues student page and a pair of scissors, as well as newsprint and markers. Each student should read his clue card and share the information with the rest of the group. Then groups should use these bits of information to synthesize definitions of the terms. When groups have agreed on the definitions, ask them to write the terms and their definitions on newsprint. When students have finished recording their group's definitions, tell them to discuss the questions on the Resource Questions student page and have a group member record group responses on a sheet of paper.
Groups present their definitions.
Resource Questions Have groups present their definitions of the three terms to the entire class and also report their answers to the questions on the student page. Simulate depletion of resources. Ask students not to tell others what the index card says. Give these students each a lunch bag. Explain to the class that the popcorn in the jar represents the world's food supply of a nonrenewable resource.
