As part of their studies on genetics, sixth-graders at Shore Road extracted DNA from bacteria cells during a recent in-house field trip.

Led by Katie McAuley, an instructor from the DNA Learning Center in Cold Spring Harbor, students were guided through the process of extracting DNA from harmless bacteria. They learned how the cell membrane protects cells and gives each one structure. To extract the DNA from the bacteria, the young scientists used soap, heat and ethanol.

In addition to the bacteria cell study, sixth-graders have also focused on animal and plant DNA during their exploration of genetics.
