Be dazzled by the brilliant colors of thousands of tropical fish swimming across your screen.
It's imperative we slow the pace of rising ocean temperatures to help bleached corals recover.
About the Video Clip
Duration: 3 minutes
Grade Level: Appropriate for all ages; content connects to NGSS standards for grades 5 and above
Shallow reefs are particularly sensitive to increasing temperatures. Warming water can cause coral bleaching, when an entire colony of coral polyps loses its color. In this clip, you'll visit the interior of an individual polyp to see how this happens.
Bleached corals are sick, but not dead. Bleached reefs can recover, which is why it's imperative we slow the pace of rising ocean temperatures.
Immersive Article: Inside Coral Bleaching
With the help of new technology, scientists are gaining unprecedented insights into a process that is changing both the face and function of our planet’s coral reefs: coral bleaching. Coral bleaching is when corals expel their colorful—and life-sustaining—algae as a result of stress. In this immersive article from bioGraphic, you can dive into a coral polyp to see both how and why this happens.
Lesson Plan: Coral Bleaching, a White Hot Problem
How does water temperature affect the health of coral reefs?
In this lesson for grades 9-12, students will examine real water temperature data for San Juan, Puerto Rico to identify patterns and make predictions about the effects of prolonged increased water temperatures on coral reefs.
