In this activity, students build a paper model of DNA and use their model to explore key structural features of the DNA double helix. This activity can be used to complement the short film The Double Helix.

This multipart animation series explores the process of photosynthesis and the structures that carry it out.

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 animation shows how mutations in an ion channel protein lead to the genetic disease cystic fibrosis. The animation also discusses how research on this protein has been used to develop treatments for the disease.

This tutorial describes the structure and function of the cancer-causing protein BCR-ABL. It also shows how drugs targeting this protein can help treat chronic myeloid leukemia (CML), a cancer of the white blood cells.

This activity explores conservation biology topics presented in the short film The Guide: A Biologist in Gorongosa. This film tells the story of Tonga Torcida, a young man who discovers his passion for science in the newly revitalized Gorongosa National Park in Mozambique.

This film is set in war-torn Gorongosa National Park in Mozambique, a protected area that has been the subject of a large-scale restoration project. The film tells the story of a young man from the local community who discovers a passion for science after meeting world-renowned biologist E.O.

This model shows the structure of the protein BCR-ABL, which causes a type of cancer called chronic myeloid leukemia.

This model shows the structure of ATP, a molecule that provides energy for cellular processes, including protein phosphorylation.

This model shows a mutated form of the cancer-causing protein BCR-ABL that is resistant to the drug Gleevec.

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

In this discussion session, biomedical scientists Charles Sawyers and Christopher Walsh answer questions from students.
