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.

Volume of Water Before adding Slide (ml) / Volume of Water After Adding Slide (ml) / Difference in Volume (ml) / Volume of the Slide

Given: 1 cm3 = 1 ml and

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…

Graduated Cylinder / Volume between Long Line and Short Line / Volume between Long Line and Medium Line / Volume between Long Line and long line
25 ml
50 ml
100 ml

**Make sure to have your teacher stamp your data sheet!

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

2. Perform each step outlined below using accurate measurements.

b.  Measure 17 ml of RED water from the beaker and pour into test tube A.

c.  Measure 21 ml of YELLOW water from the beaker and pour into test tube C

d.  Measure 22 ml of BLUE water from the beaker and pour into test tube E.

e.  Measure 5 ml of water from test tube A and pour it into test tube B.

f.  Measure 6 ml of water from test tube C and pour it into test tube D.

g.  Measure 8 ml of water from test tube E and pour it into test tube F.

h.  Measure 5 ml of water from test tube C and pour it into test tube B.

i.  Measure 2 ml of water from test tube A and pour it into test tube F.

j.  Measure 4 ml of water from test tube E and pour it into test tube D.

3. Complete the chart.

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. ______g

Measure the volume of the cube with the ruler. ______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!
