Data Explorer

This web tool provides a quick and easy way of visualizing and analyzing data without advanced technological requirements. 

Laetoli Footprints

This activity explores an image of fossil footprints at Laetoli, which serves as a phenomenon for learning about fossil evidence and human evolution.

Lionfish Invasion: Density-Dependent Population Dynamics

In this Click & Learn, students explore mathematical models that describe how populations change over time and apply these models to the invasive lionfish population in the Bahamas. They also use data from other species to learn how density-dependent factors limit population size.

Interactive Exploration of Coral Bleaching

The added information provided at pause points within the animation Coral Bleaching allows for a richer exploration of coral reefs, symbiosis, and other topics in biology.

Wildebeest Populations

This activity explores an image of a wildebeest herd on the Serengeti, which serves as a phenomenon for learning about population dynamics and wildlife management.

Modeling the Structure of DNA

In this activity, students build a paper model of DNA and use their model to explore key structural features of the DNA double helix. This activity can be used to complement the short film The Double Helix.

Evolution of Ant-Mimicking Beetles

This activity guides the analysis of a published scientific figure from a study that explored the evolutionary origins of parasitic beetles that mimic army ants.

Patterns of Predation

This activity guides the analysis of a published scientific figure from a study that investigated how herbivore populations are regulated in the Serengeti.
