Intro Metric Lab
Problem: How
can we measure the length, volume, and mass of a suilstance?
Introduction: The length of an object is measured in meters. You will
use a meter stick
provided by your instructor for the measurements. The mass of an object is defined by
how much matter the object contains. You will use the triple beam balance for the
measurements. The volume of an object is defined as the amount of space the substance
occupies at a particular temperature and pressure. You will use two different method.s to
determine the volume of a particular substance in this lab. You will work with one or
two different people for the completion of this lab.
Procedures:
1
Find object one at the table for length. Measure the length of this object and
record your answer in cm.
2.
Find object two at the table. Measure the length of this object and record your
answer in cm.
3.
Find object three at the table. Measure the length of this object and record your
answer in mm.
4.
Find object four and measure the length of this object. Record your answer in cm.
5.
What is the length of the room in meters?
6.
This one is tricky. How tall is your partner in kilometers?
Mass
1.
Find object one at the table for mass. What is the mass of object one? Record
your answer in grams.
2.
Find object two at the table for mass. What is the mass of object two? Record
your answer in milligrams.
3.
Find object three at the table for mass. What is the mass of object three? Record
your answer in grams.
4.
What is the mass of the slrgar that is inside of the beaker? Record your answer in
grams.
Volume
1.
What is the volume of the iiquid that is in jar number one? Rocord your answer in
ml.
2.
What is the volume of liquid two in jar number two? Record your answer in m1.
3.
What is the volume of object one at the table? Here, you will record your answer
in cm3.
4.
What is the volume of object two at the table? Record your answer in cubic
centimeters.
Tying in all three
Go to the last table that contains the milk carton. Follow the directions.
1.
Using the triple beam balance, find the mass of the empty milk container. Record
it in the space below.
a. Mass of empty milk carton _g
2.
Using the plastic ruler, measure the length, width and height of the empty milk
carton, in centimeters.
c. Height_cm
a. Length _cm
b. Width_cm
3.
Calculate the volume of the milk container, using the measurements of its length,
width, and height and the formula volume:1x w x h. Record your answer in the
space provided in cm3.
cm3
a. Volume of milk container:
4. Fill the milk container with water.
Find the mass of the milk container once its
filled with water and then calculate the mass of the water alone. Record your
answers in the spaces provided.
g
a. Mass of water and milk container:
b. Mass of water alone:
s
5. Pour the water from the milk container into a graduated
cylinder (Be careful not
to exceed the upper limit of the graduated cylinder. Do this several times, if
necessary, until the milk container is empty, and then add the values). Use the
calibrations on the graduated cylinder to determine the volume of water in
milliliters (m1) that was in the container. Record your answer below.
ml
a. Volume of water in the milk container:
Analysis:
1. Compare
milk container measured in step 5, to
the volume of the container itself, calculated in step 3. What oonclusions can you
draw about the size of a cm3 and the size of a ml?
the volume of water held by the
2.
Using the mass of the water calculated in step 4, and the volume of the water held
in the milk container, measured in step 5, calculate how much a single ml of water
should weigh.
3.
The density of a substance is defined as its mass divided by its volume. (D:m/v)
Calculate the density of water from the data you collected in steps 4 and 5. Show
your work below.
