Life and the EnvironmentManufacturing materials - costs etc.Project Type: Technology Introduction:
What do plastic, glass and paper have in common? For one thing, heat is required at some point when they are being made. They also can all be recycled to reduce waste. When you learn more about the manufacture and use of these materials, you can make better decisions about how to use them. Task:
Design a chart to compare the production of plastics, metals, glass, paper, and polystyrene.
Include the following categories: - Natural resources used
- Equipment and materials needed
- Energy use
- Cost
- Location
- Safety concerns
- Environmental concerns
How does recycling affect each of these categories? Time:
1 class period to conduct research, 1 class period to create chart Possible Resources: Plastics http://www.eia.doe.gov/kids/energyfacts/saving/recycling/solidwaste/plastics.html http://www.plasticsresource.com/s_plasticsresource/sec.asp?TRACKID=&CID=126&DID=228 http://www.plastics.org.nz/page.asp?id=546 Metals http://www.nrcan.gc.ca/mms/scho-ecol/toc_e.htm http://es.epa.gov/techinfo/facts/metalmfg.html Glass http://www.bsnglasspack.com/html_gb/le_verre/fabrication_verre_gb.htm http://www.civilization.ca/hist/verre/vemak01e.html Paper http://www.tappi.org/paperu/all_about_paper/paperMade.htm http://www.ptpc.com/papermaking.html Polystyrene http://www.plasticseurope.org/Content/Default.asp?PageID=277 Environmental Concerns http://www.deq.virginia.gov/p2/metalmftg.html |
