Classroom Resources

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

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. 

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

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

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.

This interactive module explores examples of how changes in one species can affect species at other trophic levels and ultimately the entire ecosystem.

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 allows students to use DNA profiling and related biological concepts to solve two cases of elephant poaching.

This interactive simulation allows students to graph and analyze sample distributions taken from a normally distributed population.

This interactive module traces the evolutionary history of birds by comparing the bone structures of a chicken to those of other species.
