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...

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...

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...

Can a coral cure cancer? Take seventh and eighth grade science sleuths to the underwater drugstore for an investigation into emerging pharmaceutical research. The fifth installment in a series of six has classmates research the wealth of...

Most drugs used today come from nature, so the discovery of new ecosystems in the deep sea is exciting from a medical perspective. Scholars develop their own bioassay to test germination rates in seeds. 

Open this lesson plan by demonstrating the production of acidic carbon dioxide gas by activated yeast. Emerging ecologists then experiment with seashells to discover the effect of ocean acidification on shelled marine organisms. They...

What do we do when a dive is too dangerous for humans to accomplish? Send in the robots! Middle school scientists get acquainted with several different models of submersible robots in the second instructional activity of six from NOAA....

If tap water is more acidic than ocean water, why are we so concerned about ocean acidification? The third installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program focuses on carbon dioxide levels in...
