In this activity, learners extract DNA from wheat germ. Use this activity to introduce learners to DNA, biotechnology and genetic engineering.

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.

The purpose of this plant biotechnology activity is to demonstrate the effect of changes in the environment on the growth and fertility of landscape grasses and crop grasses such as wheat and rice.

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).

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

In this activity (on pages 34-39), learners make a fairly detailed model of DNA using licorice and gumdrops.

In this activity, learners follow step-by-step instructions to build a gel electrophoresis chamber using inexpensive materials from local hardware and electronic stores.

In this two-part activity, learners will extract their own DNA from their cheek cells and learn how DNA is analyzed and used to solve crimes.

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

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

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

In this activity, learners construct a 3-D paper model depicting how histone, acetyl and methyl molecules control access to DNA and affect gene DNA expression.

In this activity, learners build edible models of DNA, while learning basic DNA structure and the rules of base pairing.

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

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

In this activity, learners identify the DNA base bars guanine, cytosine, thymine and adenine. Learners create a DNA model using colored paper clips to resemble these base pairs.

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