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.

In this genetics activity, learners extract DNA from an onion, using detergent solution, a food processor, and rubbing alcohol. They will also discuss genetic engineering of plants.

Using pipe cleaners, straws, and beads, learners explore the building blocks of life by creating their own model of DNA.

In this activity on page 1 of the PDF, learners compare the relative sizes of biological objects (like DNA and bacteria) that can't be seen by the naked eye.

In this activity, learners extract DNA from their own cheek cells, then create a rudimentary DNA profile similar to those seen on crime scene dramas.

In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

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

DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique. This activity allows you to see long, stringy strands of DNA extracted from wheat germ.

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

This laboratory exercise is designed to show learners how DNA can easily be extracted from wheat germ using simple materials.

This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells using simple materials.

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/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.

Learners match puzzle pieces to outlines of a DNA strand. The puzzle pieces represent the four chemicals making up DNA base pairs: adenine, thymine, guanine, and cytosine.

DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique.

In this activity, learners create a necklace of wheat germ DNA. Learners add alcohol to wheat germ so that the DNA clumps together.

In this activity, learners take on the role of various parts of the cell in order to model the process of protein synthesis.

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

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