Measurement WorksheetBackground:Scientists report measurements in significant figures. The significant figures in a measurementinclude all the digits that can be known precisely plus a last digit that must be estimated. This meansthat if your thermometer shows marks that are one degree and your liquid reaches just past 2degrees, you will call the number of the last mark (2) the known digit and then estimate within a tenthof a degree, to say, .5 or .8 or .1 of a degree, giving you 2.5 or 2.8 or 2.1. That last digit is your bestestimate, based on what you see.Significant Digits = Certain Digits + 1 Estimated DigitWhen measuring volume of a liquid, it is important to measure from the bottom of the meniscus (thecurve). You must do this at eye level, as shown below, to avoid an incorrect measurement.It is very important that you remember and use the rules we learned in class for dealing withsignificant figures. You must use these rules or you will lose points - even if your answer is correct!
