In this Click & Learn, students explore mathematical models that describe how populations change over time and apply these models to the invasive lionfish population in the Bahamas. They also use data from other species to learn how density-dependent factors limit population size.
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.
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 interactive simulation allows students to explore two classic mathematical models that describe how populations change over time: the exponential and logistic growth models.
This interactive module explores key human impacts on the environment and how they have affected Earth’s landscape, ocean, atmosphere, and biodiversity.
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 module examines Earth’s past and present climate, highlighting the effects of two important factors: solar radiation and the composition of the atmosphere.
