Bringing real-world S.T.E.M. into the classroom

Bringing real-world S.T.E.M. into the classroomHHS AP Biology students test for GMO'sHHS Biology students recently had the opportunity to examine GMO's in everyday food thanks to 3M's Commitment to Education grant for S.T.E.M. (Science, Technology, Engineering, & Mathematics) in the classroom. Mrs. Snelling, HHS biology and anatomy teacher, hopes that by incorporating more biotechnology into classes, it will push her students to pursue S.T.E.M. related jobs in the future. The grant funded two Thermal Cyclers for PCR and two gel electrophoresis machines which allows for students to conduct labs on amplifying segments of DNA and to visualize those DNA segments. Students are currently examining GMO's in processed foods and plants. A future lab will focus on students' PTC gene, TAS2R38, examining how single nucleotide polymorphisms (SNPs) can change their ability to taste the chemical phenylthiocarbamide (PTC) which allows for them to taste the bitter taste.
