Lesson 2

Lab WorkYou already know how to measure mass and you know how to measure volume. You will use those talents in the lab to determine the density of several materials. You will find instructions for this in your workbook in Exercise 12. Please note that you are supposed to measure the mass and volume as accurately and precisely as possible. This means use the skill of estimating between the lines. If you are in the lab, take time now to do this experiment, then continue with the lesson. Otherwise, you can do this exercise when you come to the lab. When you calculate the density in this experiment, you must be sure you report the density with the proper units and with the proper number of significant digits. That is you have to decide where to round off the value you have just calculated. That will be dealt with in the section on "Calculations." |
