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 Click & Learn, students explore factors that contribute to patterns seen in the Keeling Curve: a continuous record of atmospheric CO2 starting in 1958.
In this inquiry-based activity, students engage in science practices to figure out why some people with a genetic condition that usually leads to sickle cell disease do not have disease symptoms.
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 elephants with and without tusks, which serve as phenomena for learning about selection and human impacts on the frequency of traits within populations.
This activity builds on information presented in the video Selection for Tuskless Elephants. Students use scientific evidence and reasoning to construct an explanation of and develop an argument for tusklessness in elephant populations.
This interactive module allows students and educators to build models that explain how the Earth system works. The Click & Learn can be used to show how Earth is affected by human activities and natural phenomena.
