Seventh graders burst with learning

Seventh graders in teacher Kristin Suer’s class added a spring theme to their lesson as they learned about atmospheric pressure by building vacuums and exploding Peeps! Students controlled the pressure inside their vacuum chambers and steadily increased the internal pressure causing the marshmallowy Peeps to expand. Suer explained how the atmosphere does its best to maintain equal pressure, meaning when pressure increased in the chambers the Peeps expanded. However, to the student’s awe, when they released the pressure the Peeps deflated like balloons.
