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.
This activity guides the analysis of a published scientific figure from a study that explored inbreeding depression in a small, isolated population of wolves.
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.
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.
In this activity, students engage with an example from the Serengeti ecosystem to illustrate the exchange of nutrients between plants, animals, and the environment.
This activity explores images of planarians regenerating missing body parts, which serve as phenomena for learning about cell division and differentiation.
This data-driven activity accompanies the video Selection for Tuskless Elephants. It engages students in analyzing data to make evidence-based claims about the occurrence of tusklessness in elephant populations.
This interactive module consists of a virtual Winogradsky column, which can be used to explore the diversity of microbes, microbial metabolic strategies, and geochemical gradients found in sediments.
In this activity, students collect and analyze evidence for each of the major conditions for evolution by natural selection to develop an explanation for how populations change over time.
This activity guides the analysis of a published scientific figure from a study that investigated how random mutations during cell division can contribute to cancer.
This interactive module explores how mutations arise in germline and somatic cells. It also shows how these mutations can lead to genetic conditions, such as cystic fibrosis and cancer.
