Corals and Chemistry

This Corals and Chemistry lesson plan also includes:

After demonstrating the use of cabbage juice as a pH indicator, have your class experiment with their own breath, exhaling into the indicator, to show that carbon dioxide is acidic. As learners work, they also watch a video about coral reefs and how increasing atmospheric carbon dioxide also increases the carbon dioxide of the ocean water, making it difficult for coral to build strong skeletons. Consider using this lesson when teaching your class about climate change or global warming.
