Our fifth graders spent the day off campus, at the DNALC Laboratory in Cold Spring Harbor where they solved a forensic science mystery.
This three-hour lab procedure required the boys to use micropipettors and a centrifuge, and to perform gel electrophoresis. The boys loved the chance to be DNA detectives.
The boys learned about the composition of DNA, made their own models of DNA, and then worked on a lab to extract DNA from a bacteria cell, using liquid soap to break apart the cell membrane and release the DNA.
This is the second year of Saint David's collaboration with the DNALC for Fifth Grade, and the first for the Eighth Grade. Our collaboration with DNALC is enabling both grades to gain valuable hands-on experience and insights into DNA science through in-depth work conducted with DNALC scientists.
