Making MeasurementsMaking measurements properly is somewhat more involved than it may seem. The proper unit has to be selected for both the property being measured and the size. The measuring instrument must be used correctly to assure accuracy of the measurement. Also, the precision of the measurement must be noted. The pages of this section deal with those issues, beginning with the idea of estimating measurements. Next comes the concept of precision, the related practice of reading between the lines, the use of vernier scales, and the associated issue of significant digits. After that comes mass measurements using balances, volume measurements, and temperature measurements. If you have some previous experience in chemistry, you may already know much of this information and may only need to review these pages and look for new angles on topics that are familiar to you.
