Discover firsthand the effects of internal waves on coral reefs. Through a series of experiments, learners simulate internal waves and upwelling events as they make observations on the movement of water and other debris. They then...

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...

Using cabbage juice as a pH indicator, future scientists explore the effect of increasing carbon dioxide on the pH of the ocean and relate it to the health of coral reefs. Ideal for an earth or environmental sciences course, this lesson...

Explore the importance of a concentration gradient in the rates of dissolution. Using the ocean ecosystem, learners study rates of dissolution around coral reefs. A hands-on experiment helps individuals discover the effects of changing a...

How do we count the fish in the ocean? An engaging lesson models how to estimate fish populations with observational surveys. Class members begin by studying the behavior of fish on the coral reef in the oceans. They...
