Demystifying Ocean Acidification and Biodiversity Impacts
Provided by: Khan Academy |Published on: April 27, 2021
Videos Grades 9-12
Synopsis
This video is about the effects that ocean acidification has on the ocean ecosystem and food web.
Students will learn about the causes of ocean acidification, the pH scale, the rate of change in ocean pH levels over time, and ways biodiversity is impacted by these changes.
It uses principles of chemistry to explain the connections between burning fossil fuels, ocean acidification, and decreased biodiversity in the ocean food web.
It includes a transcript of the video with timestamps and a read-along feature for students who need support following along.
Additional Prerequisites
Students should have some baseline knowledge of chemical reactions.
Students should know about food webs and phytoplankton's role in the ocean food web.
Differentiation
Students in science classes could design and simulate the experiment presented at 8:53 in the video.
Math classes could use this resource as a real-world example of data that is measured using the log scale.
This resource can be directly assigned to Google Classroom if you sign up for a free account.
