Purpose:
The purpose of this lab activity is to practice:
 using a measuring tape, meter stick, a vernier caliper, and a
micrometer
 recording measurements with a proper number of significant
digits
 calculating using significant digits
 choosing an appropriate measuring device
 choosing appropriate units of measurement
EQUIPMENT:
meter stick

metric ruler

vernier caliper

micrometer caliper

measuring tape

metal cylinder

wooden block


PROCEDURE:
There are three parts to this lab. For each section, your lab
report should contain:
 a brief discussion of your procedure, which should identify
what measuring instruments you used.
 all data clearly recorded (use a data table) using the
appropriate number if significant digits and correct units.
 a sample calculation for each part.
Here's what you do:
 Determine the volume of a block of wood.
 Find the volume of a metal cylinder.
 Find the thickness of a page of paper in your text book. Think
about this. How can you get the most accurate measurement?
 Determine the volume of your classroom.
