We used wheat germ and strawberries this weekend for DNA extraction. Visitors could choose which one they wanted. It worked very well, and we were able to get at least 30 necklaces from each large strawberry.
We displayed a whole strawberry and a squished one in a ziplock. It prompted great discussions about what does, and what doesn't, have DNA.
We did Nano trainings teen volunteers and staff and had a great NanoDays@Night Family Night at The Discovery Museums earlier this month. A good suggestion from the teen volunteer presenters was to use fresh fruits for the DNA activity so that it is more relevant to the kids. They found it hard to explain what wheat germ is to some of the kids – (it’s not a germ, it used to be alive, it looked like??, etc.)
Although the dry wheat germ makes the most sense for the NanoDay Kits, we will use strawberries and/or bananas tomorrow and this week. If anyone has their favorite, please share.
And one note, my DNA necklace, made in early March still looks good and has been shared at staff and board meetings!
