EXPO #2- DNA Extraction

The second expo took place in Green Brook Middle School on January 30th 2024. Students in grades 5 through 7 were taught how to extract the DNA of their own cheek cells. The experiment displayed the concepts of cytolysis, osmosis, and hypertonic solutions. Moreover, students learned that DNA codes for all physical characteristics and its location in the cell. Students collected the precipitated DNA in small vials which they took home.
