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

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.

This activity explores images of stickleback fish, some with spines and some without spines, which serve as phenomena for learning about gene regulation and natural selection.

In this activity, students work with authentic research data to explore the impact of poaching on African elephants.

This activity explores an image of fossil footprints at Laetoli, which serves as a phenomenon for learning about fossil evidence and human evolution.

In this hands-on activity, students build a paper model to explore how CRISPR-Cas9 is used to edit genes.
