Why Lesson Planet?
In order to comprehend the workings of a quartz crystal microbalance, chemistry learners build an inertial balance. They calibrate and then use the balance to measure small mass objects. Measuring different types of foam blocks with the same volume, they are able to speculate whether they are open cell or closed cell samples. Aside from the fact that this resource was written by a college student describing his summer vacation, it holds great value for your chemistry class.
