Extracting DNA from fruit makes a fantastic science investigation. I put together three videos and worksheets around the topic, and I hope you enjoy them!
In the first video, we extract DNA from a strawberry using salt, soap, and rubbing alcohol: https://youtu.be/d2IBcOI22uI
In the second video, the little cartoon characters from my science activity books try the extraction on several different foods. For my patrons who are on the periodic table, if you ever had a life dream of having a cartoon version of you commemorated in song, it is now realized: https://youtu.be/03XCb99gl8s
In the third video, I answer several questions about the experiment and go through the worksheets: https://youtu.be/vdyNebSxX6I
If you are using this as a study unit for your child or student, I highly recommend having them work on the worksheets BEFORE watching this third video. Go to the library and look up some books about DNA, or help them use a search engine to discover the answers. They'll learn much more this way!
In the pdf file below you'll find an instruction page, two different worksheet options (one for younger students and another aimed at an older audience) as well as an answer key for the worksheets.
