If you buried a newspaper in a landfill today, your students could still read the print in 75 years—unless we teach students how to let nature’s recyclers do their work.
This kit lets students observe and compare the biodegradability of various materials in a range of environments over a period of 8-10 weeks.
Students will also prepare slides in order to study the microbial activity of various soil environments.
Includes: plastic pots, trays, sand, topsoil, pipets, hand lenses, biodegradable and non-biodegradable plastic, natural and synthetic fibers, microscope slides, crystal violet stain, protective gloves and Instructions, including teacher’s guide with answers and MSD sheets, and a reproducible student guide with background information and worksheets.
