Cool Lights

A tube worm's outer covering is made of chitin, the same material that makes up the shells of lobsters and crabs. Scholars create tube worms and analyze and discuss the longevity of organisms living near cold seeps. They then discuss and...

Young scientists access the EARTH Web site in order to engage in this lesson life forms found in the ocean. Student groups of 3 - 4 choose one set of deep-sea organism images. The groups decide how they would classify their organisms and...

Students examine bioluminescence and camouflage of deep sea creatures. In this deep sea creatures activity, students investigate the visible and near-visible light spectrum. They work in small groups to complete a light, color, and...

Your mission, should you choose to accept it, is to take your class on an underwater adventure. The final installment in a seven-part series involving salt and freshwater bodies takes junior oceanographers below the surface in...

Cooperative groups research trip logs from deep-sea expeditions and explore characteristics of deepwater habitats. Using a cake as the ocean floor, they work together to decorate it as a model of such habitats. They also prepare a...

The pressure at the bottom of the ocean is 10,000 times that at sea level. Scholars go under the sea as they learn about organisms found in the deep ocean waters. From angler fish to deep sea jellies that bioluminescence, viewers see...

Illuminate the darkest corners of your marine biology or life science class with this feature about bioluminescence. Viewers see that luciferase and luciferin combine in a cool, light-producing reaction. This adaptation helps glowing...

Learn about three different marine ecosystems: coral reefs, the continental shelf, and the deep sea. Interactive game included, which will help players chart the interrelationships among organisms that live in each ecosystem.

Bioluminescent animals are the focus of a hands-on craft in which scholars create a scene of either a land or sea bioluminescent creature.

In groups of three with the lights off and the shades drawn, investigators place inactivated light sticks, in three beakers: one filled with ice water, another with lukewarm water, and the other with room temperature water. They wait...
