Using simple, inexpensive items, learners build and test submarine models.

The objective of this inquiry-based lesson is for learners to gain an understanding of how increasing ocean acidity can affect the calcification of marine organisms.

This experiment is designed to illustrate how fluids, including water, have the ability to flow.

In this activity, learners use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.

In this activity, learners will simulate the processes of the water cycle at home in a plastic sandwich bag.

In this activity, learners explore the factors that tend to resist changes in pH of the ocean and why the ocean is becoming more acidic.
