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

This interactive video explores how two scientists tracked the 2013 Ebola outbreak in West Africa. 

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

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 order to develop complex scientific explanations, students need to have many opportunities to grapple with a concept. In this Educator Voices article, hear how Amy Fassler uses a sequence of resources in a process called “curriculum spiraling.”

Today’s world is full of pessimism and cynicism, and our students are bombarded with discouraging messages about the future of the planet. Is there any antidote to such poison? In this message from BioInteractive, hear from Vice President for Science Education Sean B.

In this article, hear from Maryland educator Laura Dinerman about how she uses our mass extinctions resources to consider how the KT extinction connects with global species declines we’re experiencing today.

Interested in using our biogeography resources to help your students reason from evidence? In this article from California educator Nikki Chambers, see how she uses our suite of ‘Wallace Line’ activities to have her students construct explanations.

Nikki Chambers describes how she uses BioInteractive posters to engage her students and elicit questions from them to guide her teaching.

This interactive module allows students and educators to build models that explain how the Earth system works. The Click & Learn can be used to show how Earth is affected by human activities and natural phenomena.
