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 collaborative activity, students explore major biodiversity threats and design, present, and refine solutions for preserving biodiversity.

The return of beavers to the British countryside is boosting biodiversity, reducing storm-induced flooding, and restoring wilderness to an over- manicured landscape.
This animation shows two examples of how the cell uses energy from ATP. It is the sixth of six animations about cellular respiration. These animations bring to life the molecular engines inside mitochondria that generate ATP, the main source of chemically stored energy used throughout the body.
This animation shows how the pyruvate dehydrogenase enzyme complex converts pyruvate into acetyl-CoA. It is the second of six animations about cellular respiration.
This animation shows how glycolysis converts glucose into pyruvate through a series of enzyme reactions. It is the first of six animations about cellular respiration. These animations bring to life the molecular engines inside mitochondria that generate ATP, the main source of chemically stored energy used throughout the body.
This video shows how a group of students, scientists, and volunteers came together to make hand sanitizer and masks for their community during the COVID-19 pandemic.
This animation shows how the proton gradient across the mitochondrial membrane powers the ATP synthase enzyme to make ATP. It is the fifth of six animations about cellular respiration. These animations bring to life the molecular engines inside mitochondria that generate ATP, the main source of chemically stored energy used throughout the body.
