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.
In this phenomenon-driven activity, students investigate how cells are signaled to make melanin and explain how mutations in melanin pathway proteins affect the coat color of various organisms.
In this activity, wildfires and how much area they burn serve as a phenomenon to guide student inquiry, which includes evaluating data and developing scientific claims.
This activity explores an image of a wildlife overpass crossing a major highway, which serves as a phenomenon for learning about habitat fragmentation and conservation.
In this inquiry-based activity, students investigate the phenomenon of fur colors in rock pocket mice to connect genotypes to phenotypes and molecular genetics to evolution.
This activity explores the concepts and research presented in the short film From Ants to Grizzlies: A General Rule for Saving Biodiversity, which explores the species-area relationship and its applications for conservation.
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.
This activity explores images of elephants with and without tusks, which serve as phenomena for learning about selection and human impacts on the frequency of traits within populations.
