This activity guides the analysis of a published scientific figure from a study on how termite mounds can enhance an ecosystem’s resilience to drought.

This hands-on activity allows students to build model food webs and then evaluate how ecological disturbances affect each trophic level.

This film explores the genetic and archaeological evidence that suggest that corn is the result of the domestication of a wild Mexican grass called teosinte.

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

This video follows biologist Liz Hadly in Yellowstone National Park as she discusses how ecosystems are threatened by warming temperatures.

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 interactive map of Gorongosa National Park in Mozambique explores different features of the park’s ecosystem and conservation strategy.

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

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

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

This animation shows how the cancer treatment Gleevec inhibits the cancer-causing protein BCR-ABL.

This animation shows why a mutant BCR-ABL protein is resistant to the cancer treatment drug Gleevec, and how a new drug can overcome this resistance.
