Campbellsville High School students recently learned about osmosis.
Students in Lauren Bennett’s AP biology class performed an experiment to see the osmosis process happen and observe the effect it has on cells.
First, students put a potato in water and then another in salt water.
After letting the potatoes sit for a day, students observed what happened. The potato soaked in salt water changed colors, texture and size, while the potato in only water didn’t change much.
Students recorded their observations and then answered questions about how osmosis changed their potatoes.
