Recycling Plastics by Density Single Kit

National Standards for Grades 3-12

Students use a flow chart template and a simple sink or float methodology to identify recyclable polymers by density. Using small pieces of plastic samples, students ultimately identify each item by recycle number to determine how the plastic should be recycled in their community. Great for introducing the concept of recycling as students may differentiate plastics they collect. Includes common sources of household plastics for each recycle category. Ideal for teaching polymer plastics: includes the properties of individual polymers, chemical structures, descriptions, and density ranges for each recyclable polymer.

Includes both support materials for teaching middle and high school topics and a differentiated lesson plan for grade levels 3-5.

Allow 30 minutes for experiment and additional time for extension activities.
