Plastics Problems and Solutions
- The 9-title Wonders of Physics and Chemistry series covers everything from the definition of an atom to the science of light. Students can start to develop basic understandings of the fundamentals of science, then work their way up to more complex subjects. Each program includes a subject specific teachers guide which includes subject matter revision and suggestions on how to present material, questions to ask students, and class projects to help illustrate the key concepts. Plastics have become a necessary addition to our modern lives. They are present in our homes, our classrooms, and our modes of transportation; plastics make life easier and more convenient. As beneficial as they can be, the creation and use of plastics also has some negative consequences. Plastics: Problems and Solutions explains the chemistry of plastics and brings to light some of the ways they have become a hindrance as well as a help. Students will learn about the impact plastics have on our environment, and what we’re doing to solve the problems of disposal and recycling.
