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.

In this genetics activity, learners discover how to extract DNA from green split peas.

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.

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

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

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

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).

In this activity, learners bake cookies by following different recipes to better understand genetic mutations. Everyone in the group bakes the same type of cookie: chocolate chip.

In this yummy biology activity (page 3 of the PDF), learners participate in a demonstration of natural selection.

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

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 count and measure kidney beans to explore natural selection and variation. Learners measure the length of 50-100 beans.

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

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection through data collection and pattern recognition.
