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.
In this inquiry-based activity, students engage in science practices to figure out ways environmental factors drive the natural selection and adaptation of Galápagos finches.
This activity guides the analysis of a published scientific figure from a study that investigated how human populations might adapt to milk consumption, both genetically and culturally.
In this inquiry-based activity, students investigate the phenomenon of fur colors in rock pocket mice to connect genotypes to phenotypes and molecular genetics to evolution.
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.
Earth desperately needs people to stop burning coal, the biggest single source of greenhouse gases, to avoid the most catastrophic impacts of climate change. But it is the world’s biggest source of fuel for electric power and so many depend on it for their very lives.
