Finding a Gene on the Chromosome Map
Source Institutions
In this activity, learners use pedigree and jigsaw puzzles to explore how scientists use genetic information from a family to identify a gene associated with a genetic disorder.

DNA From an Onion
Source Institutions
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.

What Sort?
Source Institutions
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.

Is That DNA in My Food?
Source Institutions
In this activity, learners extract DNA from wheat germ. Use this activity to introduce learners to DNA, biotechnology and genetic engineering.

Gene Switches
Source Institutions
In this activity, learners explore how genetic switches function and the role of genetic switches in the process of evolution.

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

How to Extract DNA From Anything Living
Source Institutions
In this genetics activity, learners discover how to extract DNA from green split peas.

Isolation of DNA from Onion
Source Institutions
This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells. It includes an optional test for the presence of DNA.

A Simply Fruity DNA Extraction
Source Institutions
In this activity, learners extract DNA from a strawberry and discover that DNA is in the food they eat.

Reading DNA
Source Institutions
In this activity, learners use edible models of the DNA molecule to transcribe an mRNA sequence, and then translate it into a protein.

Yeast DNA Extraction
Source Institutions
This laboratory exercise is designed to show learners how DNA can easily be extracted from yeast using simple materials.

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

A Recipe for Traits
Source Institutions
In this genetics activity, learners create and decode a “DNA recipe” for a dog by randomly selecting strips of paper that represent DNA.

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

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

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

Giant Chromosomes: Fruit Fly DNA and You
Source Institutions
Many of the genetic sequences found in the fruit fly genome are similar to those found in humans.

Thymus DNA Extractions
Source Institutions
This laboratory exercise is designed to show learners how DNA can be extracted from a chunk of thymus (sweetbread) or liver.

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

Lima Bean Bacteria DNA Extraction
Source Institutions
This laboratory exercise is designed to show learners how DNA can easily be extracted from lima bean bacteria. This experiment requires the use of a centrifuge (not included in cost of materials).
