How does plastic harm the ocean - KS3 Biology

In this biology Key Stage 3 (KS3) lesson, students learn how plastics affect the marine environment. This lesson is focuses on the physical harm caused by plastics to marine organisms. Included are teacher resources that promote students to become advocates for reducing plastic waste to protect our oceans.

This is a single lesson from the Ocean Plastics Science unit. Ocean Plastics Science is a Key Stage 3 (KS3) resource combining both biology and chemistry. Students are taken on the journey of plastic. Exploring how plastics are manufactured, used, and disposed into the ocean. Students will learn the science behind what makes plastics both brilliant for everyday purposes and devastating to our oceans and marine life.

Included in this topic are teacher resources that promote students to conduct authentic research, emulating research conducted by The University of Plymouth. Students will test the properties of plastics, investigate compostable alternatives, and analyse case studies to discover how plastics can physically and chemically harm marine life.
