Sediment samples from the ocean bottoms tell scientists about climate change, pollution, and changes in erosion for the area. Groups of learners focus on sediments and their movement through water. During a hands-on activity, they...

This unit is so cool, you won't be able to "kelp" yourself! Intended for all grades, this science and activity guide for teachers offers a unique opportunity to understand kelp's role as a valuable ecological resource. Teachers and...

For as small as they are, plankton sure play an enormous role in maintaining marine ecosystems. Dive into an investigation of these tiny organisms with a hands-on life science activity in which children cut out pictures of sea...

In the ecological game of who eats who, one small change can have a big impact! Individuals create food chains in an array of ecosystems, then determine what happens to organisms in the chain when one organism changes its feeding...

Young scientists discover how sea otters' habitats have changed due to human impact. Through conversation, video observation, and story reading, scholars identify how human interactions change a specific ecosystem in both positive and...

Around 93 percent of the reefs on Australia's Great Barrier Reef have been bleached, and almost one quarter of them are now dead. Scholars research the sea temperatures, especially around the areas with coral reefs, to make connections...

After looking at examples of biotic and abiotic factors in ecosystems, students focus on abiotic factors in marine ecosystems, the physical processes that are involved, and the impact human activities can have on these. Includes handouts...

Students define and provide examples of abiotic and biotic factors of different ecosystems. Then they investigate the importance of abiotic factors and physical processes within ocean ecosystems.

Students will learn surveying methods for an ecosystem through a short video. The video focuses on exploring the number and types of fish and the health of the coral reef ecosystem. Site includes a lesson plan and activity worksheet.
