Classroom Resources

In this activity, students use an interactive tool to simulate how scientists collected and used sample data to estimate elephant population sizes.

In this Click & Learn, students explore the process of digestion and how it connects to metabolism and cellular respiration. 

This interactive module can be used to model infectious disease spread in a population. It includes background on the SIR model and two simulators for modeling disease spread on different scales. 

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 interactive module introduces the anatomy of the immune system and walks through the timeline of a typical immune response.

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

This interactive module explores the biology of sex determination and development in humans, set against the backdrop of the different sex testing policies implemented throughout sports history.

This interactive module allows students to collect and analyze data from a virtual river to construct biomass and energy pyramids.

This interactive module uses the central dogma as a model for exploring how modern molecular biology technologies can be used to treat different genetic conditions.

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 biomes, climate, biodiversity, and human impacts around the globe and at different times.

This interactive module explores how different animals — elephants, birds, and bats — have evolved distinct ways of using sound to communicate.
