This Friday we will be doing a lab extracting DNA. Gwen’s mom is our guest expert scientist and will lead us through several steps for this investigation. Students will use cheek cells and actually extract the DNA from the cells with a kit provided by BioRad. If all goes as planned students will be coming home with strands of their own DNA floating inside a glass heart that can be worn as a necklace. We will be wrapping the hearts in bubble wrap for the trip home. We don’t encourage them to wear them to school since they are fragile. The DNA that we are extracting  is done in such a way that there is no identifiable information. If you don’t want your child to participate for any reason please let me know and speak to them so they understand. They can be science helpers that day and still participate without using their own DNA. Mrs. Colville has a molecular background and we are thrilled to have her as our volunteer Bio-Rad Science Ambassador. I do need a few volunteers to help that morning if you would like to join us. We will begin in the science lab around 9:30 and finish up in about an hour. Email me right away if you can attend please. Thanks!
