The GReen crIBS movement.

FINAL ASSESSMENT: GRIBS PROJECT Waste incineration produces excess greenhouse gases, which are dangerous to the Earth’s atmosphere. Everyday, tons of trash are

produced without thought of the impact on our environment. Why is recycling and reusing so important? How much greenhouse gas is

actually produced when plastic or paper is incinerated?

MISSION: Design a useful product using recycled paper and/or plastic. Prepare an engaging and informative presentation on the necessity to recycle and reuse. 1. Product design: Build product while carefully measuring the mass of recycled items incorporated. 2. Calculations: Calculate the amount of greenhouse gases produced IF items used in your project were incinerated at a landfill rather than recycled. 3. Presentation: Present background information on environmental effects of pollution, explain calculations, and convince audience of the need to recycle and reuse.

** Be prepared to potentially give your presentation to other teachers, students, and/or parents. ** This project will address the Unit 3 Essential Question: Quantitatively, how much pollution is produced when trash is burned?
