Demo Teaches Eighth-graders Science Lab Safety

Eighth-grade science teacher Ken Revell recently taught students about lab safety with a demonstration stressing the importance of wearing goggles in the lab. “Safety is always a concern in science, but it has been elevated to new levels with the advent of COVID-19,” Revell said. “The demonstration showed students the protective properties of splash goggles.” Revell sprayed acetone onto a Styrofoam manakin head, which was wearing goggles. “The Styrofoam dissolved wherever it came into contact with the acetone. The face and forehead of the manakin were completely dissolved, but the region under the goggles remained untouched,” he said. “This gives the students a dramatic visual of the function the goggles serve.”
