This activity explores images of tree growth in the Serengeti over time, which serve as a phenomenon for learning about and modeling species interactions in ecosystems.

This activity guides the analysis of a published scientific figure from a study that modeled the impact of an infectious fungal disease on a bat population.

In this activity, students use cards to build model food webs and evaluate how ecological disturbances affect each trophic level using information from the citizen science website WildCam Darién.

This activity guides the analysis of a published scientific figure from a study about Arctic fox populations and their main prey, lemmings.

This interactive simulation allows students to explore two classic mathematical models that describe how populations change over time: the exponential and logistic growth models.

In this hands-on activity, students simulate the effects of decreasing pH caused by rising levels of atmospheric carbon dioxide.

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

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.

In this activity, students collect and analyze data from a hands-on model to discover why even slight variations in beak size can impact a bird’s ability to obtain food and survive.

This activity engages students in learning about the mechanism of evolution by natural selection and Hardy-Weinberg equilibrium using candies to represent populations of beetles.

This activity engages students in learning about the mechanism of natural selection using candies to represent individuals of a species of clam.
