Seventh-grade students at Stewart Middle School recently used strawberries to explore the world of DNA in a hands-on, memorable way. The engaging activity was designed to deepen their understanding of genetics and biology through direct observation.
Students conducted a strawberry DNA extraction experiment by mashing the fruit to break open the cells and reveal the genetic material inside.
“This activity allowed students to actually see DNA, which helps connect abstract ideas to something they can physically observe,” said science teacher Jourdan Bunkley.
“By starting with this experiment, I wanted to reintroduce and reinforce the foundational concepts of cells, DNA and traits—since the last time many students formally studied life science was in fourth or fifth grade,” Bunkley remarked.
She went on to emphasize that transforming an abstract idea into something tangible allowed students to connect classroom vocabulary, like cells, DNA, and traits, into a real-world experience.
“It sparked curiosity and engagement, giving students a sense of discovery and ownership in their learning. The hands-on process also helped strengthen their confidence in working like scientists, making them more prepared and excited to dive into the next unit on selective breeding and inheritance of traits.” Bunkley said.
