CHEMISTRY BONUS OPPORTUNITY: Density Column


5-12pts (depending on # of layers)

You need to make a density column that has at least 5 different layers. Each layer must be clearly visible and distinct from the layers around it. For each layer that you get above 5, you will earn 1 more bonus point (12pts max). You must use a container that is smaller than 1.0 L and the layers must be clearly seen through it. You must also label each layer with the identity of the substance and its density in your drawing below (or on the back of this sheet). Densities for many substances can be found in your book, other texts, and on the web. If you are unable to determine the exact density through research or experimentation, estimate it based on where it is in the column relative to other known densities. Any estimated densities must be marked as estimated. You should have no more than two solid layers in any liquid layer.


Consider your possibilities before you start mixing substances. Use small amounts of material to determine what floats on what. Also, be aware that any flammable or hazardous materials are not allowed, (for example, gasoline and mercury.) Use your book and the Internet for help.
