Testing Physical And Chemical Properties

This lesson came about because I realized my students would have a far better understanding of what physical and chemical properties were if we did more than just talk, but actually measured these properties substances.

In this lab students perform a variety of physical and chemical tests on 4 unknown powders (salt, sugar, chalk, and baking soda). We’ll never reveal what the powders are because their identity isn’t the point of the lab; it’s kept from them so they’ll pay more attention to the behaviors of the powders.
