How Big is Small
Source Institutions
In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

Shell Shifts
Source Institutions
Ocean acidification is a big issue due to the amount of carbon dioxide humans release. CO2 in the atmosphere is absorbed into the ocean thus changing its acidity.

Coral, Carbon Dioxide and Calcification
Source Institutions
In this group activity, learners act out key stages of the "ocean carbon cycle" (also known as the "carbonate buffer system") through motions, rearranging blocks and team tasks.

Salt, Soil and Seeds
Source Institutions
Discover how the salt in soil affects plant growth with a few seeds, some cotton, and salt. In this hands-on activity, you will plant seeds in 2 different kinds of soil, containing more or less salt.

What's In Your Breath?
Source Institutions
In this activity, learners test to see if carbon dioxide is present in the air we breathe in and out by using a detector made from red cabbage.

Corals and Chemistry
Source Institutions
In this activity, learners investigate how increased carbon dioxide (CO2) emissions from the burning of fossil fuels is changing the acidity (pH) of the ocean and affecting coral reefs and other marin
