Pausing the video, turning on the closed captioning, or providing a list of keywords before the video may help some students with comprehension.
After the video, students could make posters, presentations, videos, or podcasts about how we are affecting aquatic environments and how we can protect them.
Biology and science classes could use this video when discussing bioaccumulation, food webs, photosynthesis, cellular respiration, ecosystems, oceans, ecosystem declines, species extinctions, or nonpoint pollution.
Other resources on this topic include this interactive data resource about fertilizer pollution, this PBS video about coral reefs, and this video about coral reefs in Biscayne National Park.
