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

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 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. 

In this Click & Learn, students explore factors that contribute to patterns seen in the Keeling Curve: a continuous record of atmospheric CO₂ starting in 1958.

This Click & Learn traces the flow of energy from the Sun all the way to cells within organisms. The embedded questions and calculations guide students’ understanding of how energy is distributed through a variety of ecosystems.

This tool can be used to add pause points, questions, and labels to any BioInteractive video. It also includes a library of ready-to-use videos with embedded questions.

This interactive video explores how scientists identify which bat populations are infected with Nipah virus and could transmit the virus to humans.

This film begins with phenomena linked to climate change and then examines how Earth’s temperature is controlled, how we know it is changing, and how the current changes compare to those over the last 800,000 years.

This video shows how a group of students, scientists, and volunteers came together to make hand sanitizer and masks for their community during the COVID-19 pandemic.

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

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.

In this video, ecologist Tony Sinclair takes us through the steps of how he uncovered that the eradication of an infectious disease in cattle led to a boom in the Serengeti’s buffalo and wildebeest numbers.
