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. 

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 Click & Learn traces the flow of energy from the Sun all the way to cells within organisms. The embedded questions and calculations guide students’ understanding of how energy is distributed through a variety of ecosystems.

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.

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 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 connects to an online citizen science platform for identifying animals in photos collected by trail cameras in Darién and Soberanía National Parks in Panama.

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

This interactive module explores methods used to survey large animal populations, and what they have revealed about the current state of the African elephant population.

This interactive module allows students to investigate their own ecological questions using data collected by trail cameras in Gorongosa National Park in Mozambique.
