Educational Philosophy

Education is a social process. Education is growth. Education is not a preparation for life; education is life itself.

~ John Dewey

Our simple educational philosphy: we learn as we live and we celebrate what we learn!

DNA







Today, the girls extracted DNA from peas. First they took a 1/2 cup of split peas, 1/8 teaspoon of table salt and 1 cup cold water in the blender and blended for 15 seconds. Then they poured the pea-cell soup through a strainer into another container and they added 2 tablespoons liquid detergent and they let the mixture sit for 5-10 minutes. Then, they poured the mixture into a test tube and poured rubbing alcohol down the side until they had equal amounts of alcohol and pea mixture. The DNA rose to the surface and they used a wooden stick to draw the DNA in to the alcohol. Here are some pictures. The last one shows the DNA really well.
