After a dam removal on Washington’s Elwha River, scientists are chronicling a story of ecological rebirth. Recovering salmon populations are transferring critical nutrients from the ocean into the forests, enriching the entire ecosystem.
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.
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.
In this inquiry-based activity, students engage in science practices to figure out why some people with a genetic condition that usually leads to sickle cell disease do not have disease symptoms.
This video presents an intriguing phenomenon: two patients who carry the same genetic variation, which is known to cause sickle cell disease, have very different outcomes.
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.
