In this activity, learners perform an experiment that models a chromatography-like process called electrophoresis, a process used to analyze DNA.

In this activity, learners construct a cereal chain as a model of how proteins are made in the cell.

Learners construct a bracelet containing two strands of beads, which represents a double strand of DNA that codes for a gene. They match beads to the bases in a section of a chimp's DNA code.

Whether it's the genetic code, an ancient language, or patterns of light in a distant galaxy, scientists often have to play the role of decoder.

In this activity, learners create an origami model of DNA, demonstrating its double helix structure.

This activity is about collecting and analyzing DNA as part of a criminal investigation.
