Learning outcomes

We hope that the students will realize the importance of conservation and inspire them to do their part in recycling, reusing, and reducing in their everyday lives. The students will play the dumptown game and learn how a city can reorganize itself into a recycling town and how much different recycling programs cost.

Activities

Step 1

Discussion of recycling, reusing, and reducing to show students the effect this has on the environment.

1. Talk about non-renewable and renewable resources.
2. Talk about what products that can be recycled in their community.
3. Talk about how to reduce by showing even to buy products with the least amount of packaging.
4. Talk about reusing items to create projects such as a milk cartons for a bird feeder.
5. Students should participate in the discussion by volunteering their ideas and experiences.

Step 2

Enter the EPA website and let the students explore Dumptown.

2. Click also on the link under P.S. to learn about the history of dumptown.

Step 3

Allow students to play the Dumptown Game. As they add/delete programs, let them fill out worksheet of plans they implemented, how much they spent, and assess of how the programs affect the town (what it reduced, etc.). They will do this for four trials.

1. Click on Dumptown Game under Welcome to Recycle City.
2. Let the students read the directions.
3. Click on Play the Game.

Step 4

Discuss among all the students the cheapest plans, the most benifical plans, etc.

Supplemental information

Recently, The Daily Tarheel reported that North Carolina set a new record of producing 10.2 million tons of garbage between July 1999 and June 2000. This amount of garbage is 1 million tons more than the previous year. This amount also indicates that 1.3 tons of garbage is thrown away by each resident of North Carolina. This information shows the need to reduce, reuse, and recycle.

Comments

The EPA is a great website with many opportunities to create your own learning tool. During the four trials, the teacher can set limits to the amount spent or which item of garbage to reduce.
