DNA Lab this Friday

This Friday we will be doing a lab extracting DNA. Gwen’s mom in Mrs. D.'s class 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 science background and we are thrilled to have her as our volunteer Bio-Rad Science Ambassador. We will be going to the school science lab about 8:15 am.  We have some parent volunteers to assist the students with the process. It promises to be a "Think Like a Scientist"
adventure!
