Forest Grove Middle students study molecular structure

Over 700 Forest Grove students performed a lab in which they extracted DNA from a fresh strawberry during their science class. Sixth graders learned about cells and cell theory. In seventh grade, their knowledge expanded through studying how DNA determines the genetic structure of an organism and makes each individual unique. Eighth graders continued to expand this concept by concentrating on the way that cells and DNA contribute to body systems, photosynthesis, and cellular respiration. Following this hands on activity in a wet lab setting, students could not only see, but hold and stretch the strawberries’ DNA to see the double helix shape. This truly engaging activity allowed students to know that DNA molecules really do exist. Pictured, from left, re Janira Quinones, Yadira Solis and Ariana Luna.
