Mozambique Mounds

This activity explores an image of termite mounds in the African savanna, which serves as a phenomenon for learning about ecosystems, competition, and feedback loops.

Skin Color and Human Evolution

This activity guides the analysis of a published scientific figure from a study that investigated genetic factors contributing to skin color differences, particularly within African populations.

“Fixing” Gene Expression

In this hands-on activity, students review the steps of eukaryotic gene expression and learn how this knowledge can be used to treat different genetic conditions. The activity reinforces concepts covered in the Click & Learn “Central Dogma and Genetic Medicine.”

The Search for a Mutated Gene

This video describes the case of a patient with retinitis pigmentosa (RP), a progressive disease that leads to blindness, and how physician-scientist Dr. Ed Stone approached the search for the causal mutation.

Central Dogma and Genetic Medicine

This interactive module uses the central dogma as a model for exploring how modern molecular biology technologies can be used to treat different genetic conditions.

Modeling Trophic Cascades

In this activity, students model trophic cascades, which are also explored in a variety of related resources, using cards of animal and plant species from seven different habitats.

Trophic Cascades in Salt Marsh Ecosystems

In this video, ecologist Brian Silliman explains how he uses manipulative field experiments to study salt marsh ecosystems. His approach revealed that these systems are under top-down control from consumers and predators.

Ecology, Food Webs, and the Chesapeake Bay

In this talk, scientists Beth McGee, Mary Power, and Brian Silliman discuss the Chesapeake Bay, its food web, and the challenges of conserving and restoring the Bay.

Snail Fronts and Salt Marsh Die-Offs

This activity guides the analysis of a published scientific figure from a study that investigated whether periwinkle snails contribute to salt marsh die-offs.

Viral DNA Integration

In this hands-on activity, students model how a double-stranded DNA copy of the HIV genome is integrated into the host cell DNA.
