This activity explores images of tree growth in the Serengeti over time, which serve as a phenomenon for learning about and modeling species interactions in ecosystems.

This case study follows a 2020 COVID-19 outbreak on a cruise ship to highlight how control measures like lockdown impact disease spread.

In this activity, students identify the science practices and concepts in a Wild Hope episode.

In this collaborative activity, students explore major biodiversity threats and design, present, and refine solutions for preserving biodiversity.

In this activity, students use an interactive tool to simulate how scientists collected and used sample data to estimate elephant population sizes.

In this activity, students interpret several pedigrees of autosomal dominant and recessive conditions and consider the benefits and limitations of genetic testing.

This case study follows the 2019 measles epidemic in Samoa to highlight how vaccination impacts disease spread.

This activity guides the analysis of a published scientific figure from a study that explored inbreeding depression in a small, isolated population of wolves.

This interactive tool introduces students to building scientific models. Educators can use the tool to create assignments and, in some cases, automatically grade student models. 

This activity explores an image of a wildlife overpass crossing a major highway, which serves as a phenomenon for learning about habitat fragmentation and conservation.

This interactive module can be used to model infectious disease spread in a population. It includes background on the SIR model and two simulators for modeling disease spread on different scales. 

This activity guides students through learning and using key scientific terms, culminating in the creation of a customizable diagram.
