These are fun activities kids can do at home with materials that you can usually find at home. There are also a wide range of classroom activities, many of which can be adapted to use at home.

Ponds Freeze in the Winter — Why Doesn't the Ocean?

In New England, winters are cold enough to freeze the surface of ponds and lakes. But why doesn't the ocean along the New England coast also freeze? And how do the animals that live in ponds survive when it freezes?

Counting the Fish in the Sea

How can scientists tell how many fish are in the sea? They couldn't possibly count every fish; the ocean is so big! Here's how they "count" some of the animals by making estimates.

Make Your Own Deep-Sea Vent

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.

How Animals Stay Warm

Whales and seals depend on a thick layer of body fat called blubber to keep them warm in cold New England seas. To learn how blubber works, make a "blubber mitt" and see how it protects animals from the cold.

Make Your Own Sea Otter

Sometimes sea otters have to swim through dark or murky water to find food and use their very long whiskers to feel their way to food. Make your own "otter whiskers" and use them to find objects underwater.
