Metric Measurement Lab
Part A: Water Displacement
Follow the directions to find the volume of a microscope slide using a ruler and then water
displacement.
1. Determine the volume of one microscope slide using a meter stick and calipers.
Given: length x width x height= volume
__________ x __________ x __________ =________________cm3
2. Add 50 ml of water to a 100 ml graduated cylinder. Record this amount in the chart.
3. Add the slide to the cylinder and measure the volume. Record this amount in the chart.
4. Find the difference between the two measurements and record in the chart. The
difference between the two measurements will be the volume of the slide.

Given: [ ( measured – water displacement) / water displacement ] X 100 = percent error
Question #1: Compare your two values. Are they the same? Why or why not?
Question #2: Which measurement is more accurate? Why?
Question #3: What is your percent error?
**Make sure to have your teacher stamp your data sheet!
Part B: Reading between the Lines
Examine the 25, 50 and 100 ml graduated cylinders. Each are marked with white/clear lines of
various length…short…medium…long. Determine the volumes below…

Part C: Color Challenge
3. Obtain the following items from your teacher:




3 beakers with colored water- 25 ml of each color (red, blue, and yellow)
1 graduated cylinder (25 ml – 50 ml)
1 eyedropper
6 test tubes labeled A, B, C, D, E, and F

Part D: Comparing Balances
Using the triple beam balance measure the mass of a 250 ml beaker.
_________ g
Now use an electronic balance to determine the mass of the same beaker _________g
Given: [ ( triple beam – electronic) / electronic ] X 100 = percent error
Calculate the percent error between these two devices.
****Make sure to have your teacher stamp your data sheet!
Part E: Density of a Metal Cube
Given: density = mass / volume
Given: volume = length x width x height
Given: [ ( calculated density – accepted density) / accepted density] X 100 = percent error
Obtain a metal cube from your teacher.
Record the type of metal here. ____________________________
Measure the mass of the cube with the triple beam balance.
Measure the volume of the cube with the ruler.
_________ g
_________ cm3
Calculate the density of your cube. _____________ g/cm3
Using the chart given, what is the accepted value of density for your metal?
_____________ g/cm3
What is your percent error? __________ %
**Make sure to have your teacher stamp your data sheet!
