This is a discovery learning lesson which can be adapted across multiple contexts with appropriate scaffolding from the teacher.  Students get involved in promoting recycling in their school by making posters and videos to post by the vending machines after researching the benefits of recycling.Image source for thumbnail: free clipart library

In this project, students will use knowledge of electricity and electromagnetism to collaboratively design and test a model of a magnetic recycling sorter. They will evaluate the performance of their models and propose further modifications based on the output of their magnetic device measured in mT using a Vernier probe. They will also physically test their magnets on a model of a conveyor belt containing recyclable items. Students will track their data from both tests, with the ultimate goal of creating the strongest and most effective magnet with given materials. Finally, students will present their findings and proposed final design to peers and community partners involved in the recycling industry. The entire process takes about 6 weeks. The unit is a great fit for standards within energy and engineering & design.

Just south of Atlanta’s busy Hartsfield-Jackson International Airport, Clayton County seems like an obvious place for metropolitan growth. But more homes and businesses mean a higher demand on the county’s limited water supplies.
