The goal of this lab is to show you how to formalize your inferencesMaterials and Equipment0.1M HCl (an acid) 0.1M KOH (a base)Bromothymol blue (BTB)GogglesRuler with mm markingsMaterials Not IncludedPaper towelsIntroductionInference (noun): A conclusion reached upon the basis of evidence and reasoning. Synonyms: Deduction, conclusion, reasoning, conjecture, speculation, guess, presumption, assumption, supposition, reckoning, extrapolation. Everyone often uses inferences. If someone comes in from outside and is all wet, you might infer that it is raining outside. You see a trash can rolling down the road and you might infer it is windy outside. Sometimes we use inferences to predict something. For example, you see dark rolling clouds. You might infer that it is going to rain. if you see the numbers 2, 4, 6, and 8, and you had to infer what number would come next in the pattern, you would predict 10. Inferences are even used in the sciences. For instance, a meteorologist (scientist who studies weather and climate) might gather data and, based on that data, and infer there is a high chance of rain. While inferences are in a way, an educated guess, they can be used to help guide us into greater scientific truth.In this lab, you will exercise and refine your already innate ability to make inferences into the unknown. Your inferences will be grounded in known information, and guided by science.
