Observing and Inferring I Semester 1, Unit 1LAB 1:OBSERVING AND INFERRINGNOTE TO STUDENTS: This is a dry lab. You are only expected to perform the portions of this lab that do not require youto use laboratory equipment or supplies. When appropriate, sample data may be supplied in the lab's data tables to helpou answer the uestions.GoalsYou are already an inference maker. The goal of this lab is to show you how to formalizeyour inferencesMaterials and Equipment0.1M HCI (an acid)0.1M KOH (a base)Bromothymol blue (BTB)GogglesRuler with mm markingsMaterials Not IncludedPaper towelsIntroductionInference (noun): A conclusion reachedupon the basis of evidence and reasoning.Synonyms: Deduction, conclusion,reasoning, conjecture, speculation, guess,presumption, assumption, supposition,reckoning, extrapolation.Everyone often uses inferences. Ifsomeone comes in from outside and isall wet, you might infer that it is rainingoutside. You see a trash can rolling downthe road and you might infer it is windyoutside. Sometimes we use inferences topredict something. For example, you seedark rolling clouds. You might infer that itis going to rain. if you see the numbers 2, 4,6, and 8, and you had to infer what numberwould come next in the pattern, you wouldpredict 10. Inferences are even used inthe 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 educatedguess, they can be used to help guide usinto greater scientific truth.
