Warm Up: Examine the following graph.

What trend does the graph show? Why do you think this is happening?

Question: How are coral reefs affected by high temperatures and acidic water?

In the Caribbean, water temperatures typically range from 24 °C to 30 °C. What do you think might happen if temperatures rise much higher than 30 °C?

HS-ESS3-5

The pH of a solution is a measure of how acidic or basic it is. The greater the pH, the more basic the solution is. Corals and other marine invertebrates require less energy to make their exoskeletons and shells when ocean water is slightly basic. As carbon dioxide concentrations in Earth’s atmosphere rise, ocean water absorbs carbon dioxide and becomes more acidic. This process is called ocean acidification.

How do you think ocean acidification will affect coral reefs?

Many scientists predict warmer oceans, and lower ocean pH in the future. If this occurs, how do you think these changes will affect Caribbean coral reefs?
