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 case study follows a 2020 COVID-19 outbreak on a cruise ship to highlight how control measures like lockdown impact disease spread.

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

This highly customizable activity guides students through organizing and documenting spreadsheet data during a class investigation.

This case study follows the 2019 measles epidemic in Samoa to highlight how vaccination impacts disease spread.

This interactive tool introduces students to building scientific models. Educators can use the tool to create assignments and, in some cases, automatically grade student models. 

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 activity, students engage in key science practices that scientists used to figure out ecosystem dynamics in the Serengeti.

This activity guides students through learning and using key scientific terms, culminating in the creation of a customizable diagram.
 

This activity provides three sets of cards that can be used to reflect on the nature and dimensions of science.
 

In this inquiry-based activity, students engage in science practices to figure out ways environmental factors drive the natural selection and adaptation of Galápagos finches.

This activity explores the concepts and research presented in the short film Out of the Ashes: Dawn of the Age of Mammals, which explores how life on Earth recovered after a major asteroid impact.
