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.

Why Two Heads?

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

Cancer Cell Invasion

This activity explores an image of tumor cells invading muscle tissue, which serves as a phenomenon for learning about cancer, mutations, and cell division.

Living Together

This activity explores images of the bobtail squid, which serve as phenomena for learning about symbiosis and interspecies interactions.

Role of p53 in the Cell Cycle

This activity analyzes a published scientific figure from a study that investigated the role of p53 in cell cycle regulation.

Stalking the Genetic Basis of a Trait

This activity supports the film Popped Secret: The Mysterious Origin of Corn. Students analyze data on the expression of the tb1 gene to explain how variations in this gene played a role in the evolution of corn.

Root Movement

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

Science Says: Unavoidable typos in DNA help fuel cancer

Cancer patients often wonder “why me?” Does their tumor run in the family? Did they try hard enough to avoid risks like smoking, too much sun or a bad diet? New research suggests random chance may play a bigger role than people realize.

Selective Breeding in Maize

This activity guides the analysis of a published scientific figure from the world’s longest-running controlled artificial selection study, in which scientists tested whether they could use selective breeding to change the protein concentration of maize (corn).

The Teosinte Hypothesis

In this activity, students further explore the short film Popped Secret: The Mysterious Origin of Corn, by working through the mathematical concepts behind George Beadle’s claim that teosinte is the wild ancestor of maize.

Synchronized Division

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