Core Balance Passes Physics Test in Chemistry Class
Students in Roger Shelton's chemistry class recently observed a bonus lesson in physics: an unexpected encounter between a backpack in motion and a lab balance at rest.
Shelton teaches at Newfound Regional High School in Bristol, N.H., where his students were making solutions for a chemistry lab activity. Class was over, the bell rang, and the students began to clean up their equipment. An energetic student with a massive backpack popped into the room, eager to show his friends a game on his phone. As he spun around, his backpack swiped across one of the tables, sending everything on the table flying into the air. Unfortunately, that included a lab balance.
