TamperEvident Background Information Careful observation is the foundation of science, leading to questions about what we have observed - how, what, why? Observation and experimentation are twin pillars of a scientific method. This method is not a one way path, it is a process of discovery. The process of discovery continues when we design experiments to test possible answers to these questions. The three substances used in this demonstration are all common chemicals. Sodium bicarbonate, or baking soda, is used as a food additive in baking. It is also used as a natural deodorant to remove odor-causing chemicals in refrigerators and in carpets. Calcium chloride ("road salt") is a salt-like compound that is used as a de-icer for sidewalks and roads. Phenol red is a naturally occurring dye that is used as an indicator-it changes color under different conditions. Note: Phenol red is a solution of the dye dissolved in water. Water should be considered as a fourth substance (variable) in the overall reaction, and its effect should also be examined. When three substances-solid calcium chloride, solid sodium bicarbonate, and a solution of phenol red in water-are mixed, a series of changes is observed. These observations include temperature changes, color changes, and changes in state. How can we learn more about the individual interactions responsible for each observation? Imagine that each substance in the mixture represents a variable. By changing only one variable at a time, it should be possible to determine the contribution of each substance to the changes observed for the overall reaction. Materials III lıli
