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 activity guides the analysis of a published scientific figure from a study that investigated physiological and genetic adaptations in the Bajau, a group of people who traditionally do freediving.

This interactive module explores biomes, climate, biodiversity, and human impacts around the globe and at different times.

This activity analyzes a figure showing the atmospheric carbon dioxide concentration from 1958 to 2023.

The activity introduces students to the concept of biomes, using Gorongosa National Park as a case study. Part of the activity involves exploring the Gorongosa National Park Interactive Map.

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 the circulatory systems of major vertebrate groups to gain insights into their evolution.

This activity guides students through building a conceptual model of how carbon dioxide affects Earth’s climate.

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