This week, ninth-grade students in Cary Glaser’s biology class collaborated with third graders for a strawberry DNA extraction experiment. They used funnels and cloth to create a mixture of mashed strawberry and extraction buffer before adding ethanol and observing strands of DNA clumping together. With Katie Schlicht, our Lower School science teacher, our third graders are learning about inheritance and genetic traits. “To see the DNA really made it concrete for them,” Mrs. Schlicht said. “We inherit our traits through our DNA which is contained inside our cells. So, our unit of study really connected to this lab. And having the Upper School students work with them was a great opportunity.”
