This interactive module allows students and educators to document, annotate, and reflect upon scientific research processes.

In this activity, students analyze aspects of a scientific paper that investigates genes involved in the colors and patterns of butterfly wings.

This hands-on activity engages students in asking questions about phenomena using collections of images.

This activity allows students to formulate and analyze scientific questions.

In this activity, students will be guided through making observations using trail camera data collected in Gorongosa National Park, developing and investigating a scientifically testable research question, and analyzing their results.

This activity supports concepts covered in the film The Making of a Theory. Students develop their nonfiction reading comprehension by analyzing excerpts from texts written by Charles Darwin and Alfred Russel Wallace.

This three-part animation series explores the biology of the virus SARS-CoV-2, which has caused a global pandemic of the disease COVID-19.

This activity explores images of elephants with and without tusks, which serve as phenomena for learning about selection and human impacts on the frequency of traits within populations.

The added information provided at pause points within the animation Coral Bleaching allows for a richer exploration of coral reefs, symbiosis, and other topics in biology.

In this activity, students learn about the factors that regulate the population sizes of wildebeest and buffalo in Serengeti National Park.

In this activity, students evaluate a science news article to determine whether it is a trustworthy source of information.

In this activity, students find a scientist with whom they can relate in some way and then explore and reflect upon the impact of that scientist’s work.

In this activity, students evaluate a science news article to determine whether it is a trustworthy source of information.

This activity allows students to formulate and analyze scientific questions.

This interactive, modular lab explores the evolution of the anole lizards in the Caribbean through data collection and analysis.

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

This interactive module explores the diversity of viruses based on structure, genome type, host range, transmission mechanism, replication cycles, and vaccine availability.

This interactive module explores the phases, checkpoints, and protein regulators of the cell cycle. The module also shows how mutations in genes that encode cell cycle regulators can lead to the development of cancer.
