Miss Clendening’s fourth graders have been learning about Genetics and DNA. On Tuesday students traveled to the Southern Chester County Police Station to learn how the police use DNA. They were taught what types of DNA the police collect and how the police use it to solve crimes. Officer Raimato showed students how police collect DNA without contaminating evidence. The students also participated in a video conference call with Sarita Chauhan, a former parent and scientist, to learn more about DNA and ask an expert questions. Here is a fun fact from our learning, identical twins have identical DNA but they do not have the same fingerprints!
