“Everything You Need to Know About Getting DNA Out of Strawberries” is a useful and charming classroom resource from the National Human Genome Research Institute’s educational team in support of the Institute’s traveling exhibit, Genome: Unlocking Life’s Code: https://unlockinglifescode.org/node/653.
Getting DNA from strawberries was a very popular hands-on activity in the live exhibition, and this free downloadable “How-To” poster and informative 10-minute video teach the procedure from start to finish. Watch and learn how to extract DNA using items from your own kitchen with expert guidance from NHGRI Director Dr. Eric Green and the Chief of the Education and Community Involvement Branch, Dr. Carla Easter.
Never has strawberry DNA extraction been simpler or more user-friendly! Using the video, or poster, or both, lead your classes through DNA extraction that requires only a re-sealable plastic bag, fresh or frozen strawberries, dish detergent, salt, water, plastic cups, a coffee filter, cold rubbing alcohol, and a wooden coffee stirrer. The 10-minute video uses a low-key approach but sneaks in a lot of information, with clear explanations of each step, scientific terms, and mild humor. The printable color poster is clear, colorful, and can effectively stand alone, but it’s most valuable as a “recipe” for easy reference after watching the video.
This enjoyable and informative resource brings DNA science into your own kitchen or classroom. Drs. Easter and Green are engaging and fun as they explain the process of DNA extraction and the reasons behind each step. Unlike many science demonstrations surrounded by warnings and precautions, after this exercise you can whole-heartedly encourage your students to “Try this in your own home!”
