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

New research suggests humans lived in South America at the same time as now extinct giant sloths, bolstering evidence that people arrived in the Americas earlier than once thought.

An ancient human cousin may have buried its dead and carved symbols into cave walls, surprising findings for a creature with a small brain.

DNA is all around us — even in the air we breathe. Now scientists have found that air quality monitoring stations — which pull in air to test for pollution — also pick up lots of DNA that can reveal what plants and animals have been in the area.

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

Asking scientific questions is a foundational skill that takes instructional support for students to develop. In this article, Bernice Brythorne outlines how she uses BioInteractive resources to get her students to formulate and refine scientific questions. 

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.

Scientists are studying dogs around the Chernobyl nuclear power plant to see whether anything in their genes helped their families survive the harshest, most degraded environments.

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.

Professor Melissa Haswell details a multiweek virtual model to develop basic scientific knowledge and skills using BioInteractive resources that culminates in an eight-week-long animal behavior research project.

Scientists who tracked humpback whales in Australia noticed that fewer whales wailed to find mates as their population grew.

A new study that analyzes data from more than 50,000 amateur stargazers finds that artificial lighting is making the night sky about 10% brighter each year.
