Tips for teacher:
Have students use science journals or lab notebooks to record observations and notes.
Before isolating DNA, review lab safety, measuring accurately and contamination procedures.
Do not use toasted wheat germ.
A glass stirring rod or long cotton swab can be used to isolate the DNA instead of a wooden stick.
Be sure students shake gently in Step 5. It helps to minimize the amount of foam to be removed in Step 6. (See DNA Extraction Handout.)
Laminate the DNA Extraction Handout, so it can be used more than once.
Contact the Biotechnology Learning Center staff at biotech@childrensmuseum.org for help with the extraction.

Bonus
Extending Experiences
DNA can be extracted from onions, strawberries and kiwi as well. Check out this Website for protocols.
Try the DNA Dance©; see University of Wisconsin Website for directions.
Turn this activity into an experiment by having the students change a variable, such as the amount of soap used, or the temperature of the water and/or alcohol.
See how many words students can make using the letters found in the words deoxyribonucleic acid.
