DNA Extraction

With six days left until school is out and all the social studies objectives covered, I asked the kids what they wanted to learn about... the votes are in and they wanted to learn about genetics and DNA.  Wow, I was impressed!  I found curriculum that was 3rd grade appropriate.  We learned about Punnett Squares (see below) to understand the genes we get from our parents, we extracted DNA from a banana and tomorrow we will create DNA models with Twizzlers, toothpicks, and mini marshmallows.
