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.

This is an educator-led demonstration of microarray technology using a model created from a pizza box and ping-pong balls.

Learners mark their traits for tongue rolling, PTC tasting (a harmless, bitter chemical), and earlobe attachment on tree leaf cut-outs.

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.

In this hands-on activity, learners track and record the passage of colored "pompom traits" through three generations of gingerbread people.

In this activity, learners are challenged to track and record the passage of colored pom poms (representing genes) through generations of a family using a pedigree.

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 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.
