This video provides information on phytoplankton, the microscopic photosynthetic organisms that live throughout the ocean.
Students will learn how warming ocean waters are affecting phytoplankton populations and how decreases in phytoplankton affect the ocean food web and the ocean's ability to turn carbon dioxide into oxygen.
The video features easy-to-follow narration and simple animated graphics.
Students will make the connection between the phytoplankton population and the health of the ocean ecosystem.
Students should be familiar with the terms nutrients, photosynthesis, and carbon sinks.
The graphics in the video are dated, but the information in the video remains valid.
The video can be integrated into a lesson on CO2emission rise and the impact on ocean ecosystems, specifically on food webs and biodiversity within those ecosystems.
Students could research how scientists gather data about phytoplankton from satellites and what pattern that data shows.
This resource is a well-produced and well-presented 6-minute video that describes the roles that phytoplankton play in our ocean and earth ecosystems. Experts are interviewed and animations are included that demonstrate and show the topics being discussed. This resource is recommended for teaching.
