This activity relates water temperature to fishery health within inland freshwater watersheds as a way to explore how environmental factors of an ecosystem affect the organisms that use those ecosystems as important habitat.

In this activity from NOAA's Okeanos Explorer Education Materials Collection, learners investigate how methane hydrates might have been involved with the Cambrian explosion.

Students investigate how sea levels might rise when ice sheets and ice caps melt. By constructing a pair of models, students can observe the effects of ice melt in two different situations.
