The Scientific Method
This experiment was performed by using a systematic approach to identify six unknown substances. In the first half of the experiment six unknown substances were observed than measured by determining volume, mass and density. The second half of the experiment the unknown were placed in a test tube and tested for solubility. It was determined that the six tubes contained coffee, potting soil, brown sugar, baby powder, baking soda, and powdered sugar. By the use of the scientific method each unknown subject could be identified.
The contents of unknown samplers are as follows: #1 coffee, #2 potting soil, #3 brown sugar, #4 baby powder, #5 baking soda, #6 powdered sugar.

Procedure: The unknown substances were removed from a bag. Next, volume, density, and mass were calculated using small paper boats, a digital scale, and a formula which called to divide the mass by the volume. Then, the texture, shape and appearance of each substance was observed and recorded. Lastly, each substance was tested for solubility in distilled water.
