White Before Your Eyes Lab September 28, 2016 Observing Physical and Chemical Properties of Matter Purpose: Will observing the physical and chemical properties of matter be useful to classify matter? To observe reactions of different white substances with different liquids, to determine the properties based on the changes that may happen. To learn how to describe the physical properties of substances, identify physical and chemical changes, and classify the substances by their chemical properties. Hypothesis: If white matter undergoes a chemical change then it has the chemical property of reactivity. If there is a chemical reaction with the white substances then the white substances have the chemical property of reactivity. If a chemical change is not observed then the white matter underwent a physical change.
