Introduction: The purpose of this lab was to differentiate chemical changes from physical changes. During the separation lab we were given a test tube with Styrofoam‚ sand‚ salt‚ and Iron fillings in it‚ our goal was to issolate each component from the other. We were given certain tools and materials to help us figure out how to divide the components‚ therefore creating our lab. Doing this lab helped us figure out what component used physical change and which used chemical change‚ it also showed

Derricka Joe Period 5 1 Oct.‚ 2014 Lab Experiment One: Physical Properties Lab Analysis: For our first unknown‚ we observed the color and odor of the substance. The substance was a clumpy‚ white‚ crystal-like substance and it smells like new plastic. When we tested the solubility in water it resulted insoluble and in ethanol it resulted soluble. This substance could not be tested for electrical conductivity because the water was insoluble. We then tested for the PH value and it was neutral. The
