Learners observe a model of a cell and its chromosomal DNA made from a plastic egg and dental floss. Use this model to illustrate how much DNA is held in one cell.

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

In this activity, learners examine their fingerprints and learn that they can be categorized by shape, but each fingerprint is unique.

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

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 genetics meets math activity, learners take inventories of their own easily-observable genetic traits and compare those inventories with other learners in groups.

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

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

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

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.

In this activity (on pages 22-33), learners do the kind of work genetic scientists do, sorting and comparing (images of) genetic material strands called chromosomes.

In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).

In this activity, learners play a matching game with their families to discover common inherited traits and traditions. Learners distinguish between inherited traits and learned traditions.
