My students need this kit on 'Recyclable Plastics' to explore the properties of recyclable plastics. The purchase of this one kit will provide lab equipment for 68 students.
My students devour knowledge at a rapid pace. For every sentence I speak, they ask dozens of questions. They push the limits of my knowledge and I am constantly learning along with them. I am honored to work with this group of hardworking, genuine, and curious students.
I love to see the joy they have when they discover new things.
My students get extremely engaged when they connect the science that they learn in the classroom with current events, economics, and history. The class I am teaching this term aims to make those connections happen.
The elephant population was being decimated in the 1800s as the demand for ivory soared. One of the major uses of ivory at that time was for billiard balls. To ensure a smooth roll, billiard balls required extremely pure ivory. 50 tusks had to be harvested to provide enough high quality ivory for one high quality billiard ball.
The first synthetic plastic ever made, celluloid, was designed to be a replacement for this ivory.
It would be a solution to the issue of the declining elephant population. It is quite interesting that the solution to one environmental problem bred another - that of plastic waste!
In our unit we will be exploring the origins of plastics manufacturing (how and why), the chemistry/molecular structure of current plastics (for example, what is the difference between polyvinyl chloride and polyethylene), and the challenges of recycling all that plastic that we produce.
As part of the unit, I would like students to perform a laboratory unit on the physical and chemical properties of plastics. This kit will provide the materials necessary.
After learning about the history and chemistry of plastics via lecture and completing the laboratory activity, students will be doing a project in which some students will play the role of EPA regulators and others will play the roles of parties with interests either for or against a new rule regulating reduce plastic waste in the United States. During the hearing, experts on all sides will argue for their position on plastics and will propose changes to the Regulation. This part of the project does not require money, but it would be really great if we could precede this part of the project with the lab activity!
