Search Results

In this outdoor activity, learners search for lichen, a combination of a fungus and an alga living together. Lichen grow where most other plants cannot, on rocks, the trunks of trees, logs and sand.

In this activity (on pages 22-24 of the PDF), learners match extreme enviroments with life forms they support.

In this activity, learners build one or more edible coral polyps and place them together to form a colony.

In this culinary activity, learners use multiple senses (sight, smell, touch, and taste!) to explore real seaweed samples.

In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).

This activity focuses on interactions within Earth systems and the effects of human activities. In this activity learners build a biomass pyramid.

In this activity, learners model estuaries, artificially enriching both fresh and salt water samples with different amounts of nutrients and observing the growth of algae over several weeks.

In this activity, learners will collect, dry and press seaweed over the course of four days in a similar way that artists/crafters press flowers.

In this activity, learners use sets of cards to assign microorganisms to different groups.
