This "concept demonstration" provides learners with a concrete example (a pair of shoes in a classroom "cell") of what homology means.

In this genetics activity, learners discover how to extract DNA from green split peas.

In this activity, learners extract DNA from a strawberry and discover that DNA is in the food they eat.

In this activity, "write" a secret message in genetic code as beads on a string.

In this activity, learners construct a model of DNA to better understand the structure of DNA and protein synthesis.

In this simulation game, learners play as predators equipped with genetically different “mouths” (utensils) and hunt for “prey” (assorted beans).

In this activity, learners bake cookies by following different recipes to better understand genetic mutations. Everyone in the group bakes the same type of cookie: chocolate chip.

In this activity, learners make critters out of recyclables and apply the rules of mathematics to solve genetics problems.

In this activity, learners explore genes and traits. Learners investigate their fingerprints and learn how to categorize them.

In this activity, learners make their own edible DNA double helix out of candy and find out about the shape of DNA.

In this activity, learners make a 3-D model of DNA using paper and toothpicks. While constructing this model, learners will explore the composition and structure of DNA.

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.

This activity (on pages 7-13) has pairs of learners survey an array of similarities and differences between them.

Extract your DNA from your very own cells! First, learners swish salt water in their mouth to collect cheek cells and spit the water into a glass.

In this bilingual (English/Spanish) activity, learners create family trees by tracing the hands of their family members.

In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.
