Today in class we further developed our skills of using particle models to explain phenomena related to gases. The students were given the task of coming up with two different ways to inflate a balloon while it is inside of a rigid container that contains a small hole at the bottom. While all of the students were eventually able to come up with two solutions, the true challenge was to think about what was going on a the molecular/particle level that actually caused the balloon to inflate and how to represent those changes.
The skill of drawing accurate particle models and using them to solve problems with challenging scenarios will be very valuable when it comes time for assessment.
