The single most reusable full curriculum on plastic and marine debris. Three units (sources, effects, solutions) and 16 lessons span K–12 and include a waste audit, citizen science and an advocacy lesson. Next Generation Science Standards (NGSS) disciplinary core ideas are listed (LS2, LS4, ESS2, ESS3, PS1, ETS1). Because it is a US Government work it is in the public domain, which is why our own Classroom Plastic Audit adapts its waste-audit method with credit.
Who made and funded this: US National Oceanic and Atmospheric Administration (NOAA) Marine Debris Program (US federal agency) with Ocean Conservancy; public funding. How to use it: download the PDF; adapt freely with attribution to NOAA. Public domain.
