In this activity, learners explore how salt water freezes in comparison to fresh water.

In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

In this simulation, learners explore how ocean currents spread all kinds of pollution—including oil spills, sewage, pesticides and factory waste—far beyond where the pollution originates.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

In this activity about camouflage, learners create a model that shows how a flounder is able to blend into a variety of environments.
