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 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 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.

This video describes how scientists silence different genes in regenerating planaria to study the process of regeneration at the molecular level.

A number of questions are embedded within the short film The Making of the Fittest: The Birth and Death of Genes, which illustrates how gene duplications and mutations have led to remarkable physiological adaptations in Antarctic fish.

This interactive module explores key human impacts on the environment and how they have affected Earth’s landscape, ocean, atmosphere, and biodiversity.

This video provides an overview of the types of genes that, when mutated, can lead to the development of cancer.

This interactive module examines Earth’s past and present climate, highlighting the effects of two important factors: solar radiation and the composition of the atmosphere.

This interactive module explores how the changes in oxygen levels throughout Earth’s history have impacted the planet’s environment and types of life.

This animation provides an overview of the greenhouse effect, a process that warms the atmosphere and surface of Earth.

This animation explores how carbon enters the atmosphere and can be removed through a series of chemical reactions.

This film explores how gene duplications and mutations have led to remarkable physiological adaptations in Antarctic fish.
