THEME: Our waste stream has changed over time, reflecting technology advances, increased wealth, and changes in social behavior.
GOAL: Students will understand that changes in the composition of the waste stream depend on our habits and lifestyles.
METHOD: Research and completion of worksheet
SUBJECTS: Language arts, social studies
SKILLS: Analyzing, comparing, researching
MATERIALS: "Then and Now" worksheet
TIME: 1 hour, plus additional time for research
Ask students how life today differs from life in the 1800s. How would these differences affect the kind and amount of waste produced?
- Ask students to make a list of items they use every day (e.g., kitchen appliances, clothing, tools, machines, types of transportation, food).
- As a class, go over the students' lists. Do any patterns emerge? What kinds of lifestyles require these products? What do these products tell you about our priorities?
- Have each child pick one item from their list and research its equivalent from one or two hundred years ago. Have students complete the "Then and Now" worksheet and draw pictures or construct an artifact of their item for a class display.
- Discuss the differences between the products used during each time period. Ask the class: What do the products tell you about the lifestyles and the way people spent (or spend) their time during each time period? Can you tell what was (or is) important to the people in each time period? How might these differences affect the generation and disposal of solid waste?
- Have the students, individually or in groups, invent an alternative to a modern convenience that uses few, if any, nonrenewable resources, is designed to last a long time, and will not adversely affect the environment when its useful life is over.
