Red Tattoo

This activity explores an image of tattoo ink particles inside cells, which serves as a phenomenon for learning about the structure and color of human skin.

Sodium Channel Evolution in Electric Fish

This activity guides the analysis of a published scientific figure from a study that investigated how gene duplication contributed to the evolution of electric fish.

Why Two Heads?

This activity explores images of planarians regenerating missing body parts, which serve as phenomena for learning about cell division and differentiation.

Root Movement

This activity explores images of plant cells and structures, which serve as phenomena for learning about how plants respond to stimuli.

Sleep Clears β-amyloid from the Brain

This activity analyzes a published scientific figure from a study that investigated the biological importance of sleep. In this study, scientists tested whether sleep plays a role in removing harmful substances from the brain.

Synchronized Division

This activity explores an image of early embryonic cells, which serves as a phenomenon for learning about cell division and development.

Learning from Past Extinctions

In this talk, biologist Anthony Barnosky discusses Earth’s five mass extinctions and whether current species declines may be part of a sixth mass extinction.

Sizing up the Brain Gene by Gene

In this talk, biomedical scientist Christopher Walsh discusses how DNA sequencing technology has led to a better understanding of the genes involved in brain development.

Decoding the Autism Puzzle

In this talk, biomedical scientist Christopher Walsh discusses how DNA sequencing techniques have led to a better understanding of the genetic basis of autism.

Finding the Crater

This activity supports concepts covered in the film The Day the Mesozoic Died. Students will analyze geological evidence from ten different sites around the world to predict the location of the asteroid impact that caused the mass extinction at the end of the Cretaceous Period.

Weighing the Evidence for a Mass Extinction: On Land

This activity supports concepts covered in the short film The Day the Mesozoic Died. Students analyze graphs and data on pollen grains and fern spores to form a picture of the living landscape before and after the mass extinction that marked the end of the age of the dinosaurs.
