Dead Zones in Coastal Ecosystems

This activity guides the analysis of a published scientific figure from a study on low-oxygen areas in the ocean called dead zones.

Written in Chalk

This activity explores images of chalk formations and coccolithophores, which serve as phenomena for learning about the interactions between biological and geological processes.

Ocean Acidification

In this hands-on activity, students simulate the effects of decreasing pH caused by rising levels of atmospheric carbon dioxide.

Surveying Gorongosa's Biodiversity

In this video, biologists Piotr Naskrecki and Jennifer Guyton identify and record the diversity of species in Gorongosa National Park’s Cheringoma Plateau.
