In this card activity, students investigate the functions of major digestive organs.

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 Click & Learn, students explore the process of digestion and how it connects to metabolism and cellular respiration. 

This Click & Learn traces the flow of energy from the Sun all the way to cells within organisms. The embedded questions and calculations guide students’ understanding of how energy is distributed through a variety of ecosystems.

Scientists who tracked humpback whales in Australia noticed that fewer whales wailed to find mates as their population grew.

As Latinos age in the Rio Grande Valley, the border region is experiencing a surge of dementia-related disease – pushing scientists to find out why.

Our Medieval ancestors left us with a biological legacy: Genes that may have helped them survive the Black Death make us more susceptible to certain diseases today.

A new study finds that some people really are “mosquito magnets” and it probably has to do with the way they smell.

Scientists have discovered the world’s largest plant off the Australia coast — a seagrass meadow that has grown by repeatedly cloning itself.

If you're interested in using facilitated discussions to promote scientific literacy and empower students to make evidence-based decisions, this article from professor Holly Basta details how she restructured her course to promote student questioning and talk.

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.
