Here is an outline of the activities for Day One. First, we did this physics math pretest. It took all class period taking the test and reviewing the answers. This is important information; one of the kids did not know how to convert units. Next, the class did the Accuracy and Precision Lab and finally Bowling for Density.
This other density lab we did is It's all about Density from Flinn Scientific. The kids determine if which method, volume by displacement or volume by geometry is more accurate. The class can determine which method is more accurate by determining the density of a variety of objects and comparing the densities they derive with know values. My wife and I both use this lab for Chemistry and Physics. We use density blocks and have a set of mini cubes like these. We use household objects: toy block, marbles, small balls, cylinders, etc. The kids must use a variety of objects for the lab. Some of the objects will not fit into the graduated cylinder---deliberately! This is an opportunity to introduce percent error to the class. Below are photos of the equipment.
