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

In this activity, learners start their own field journal to better understand the wildlife in their area.

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 simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

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

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.

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

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 create an origami model of DNA, demonstrating its double helix structure.

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

Can you avoid the body's immune system and make someone sick? Play this online game in which you go inside a human body to explore how viruses attack cells in the body.

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

This activity lets learners participate in the process of reconstructing a phylogenetic tree and introduces them to several core bioinformatics concepts, particularly in relation to evolution.

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 craft-based activity, learners make DNA sequence bracelets that carry the code of an organism such as a human, trout, chimpanzee or butterfly.

In this activity, learners work in groups to match craft sticks that represent chromosomes. Learners must define critical attributes of their chromosomes as they look for matching chromosomes.

This is a quick game about self-assembly (page 2 of PDF under Self-Assembly Activity). Like the molecules of DNA, learners will self-assemble into a pattern by following a simple set of rules.
