In this activity on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.

In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.

Investigate the interaction of liquids of different densities and experiment with wave patterns with this hands-on activity.

In this activity (Lesson 1), learners work in groups to create tide simulations.

In this activity, learners use tsunami time travel maps to predict how long it will take a tsunami to reach the shore.

In this simulation activity, learners observe what can happen when ocean waves churn up water and oil from an oil spill.

In this activity, learners interact with whale artifacts such as replicas of skulls, bones, teeth, and baleen (hair-like plates that form a feeding filter).

In this simple activity, learners explore ocean waves. To find out if water moves forward toward the shore, learners create waves in a simulated ocean (small aquarium tank of water).

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