In this two-part activity, learners will extract their own DNA from their cheek cells and learn how DNA is analyzed and used to solve crimes. In the first experiment, learners extract DNA from their cheek cells. In the second experiment, learners use chromatography to separate mixtures of food coloring. Learners will discover that every individual has unique DNA and learn that forensic scientists use DNA to help solve crimes. This activity includes a number of optional extensions where learners can extract DNA from foods, fingerprint themselves, or use a genetic test to find out if they are super tasters.
