Station 1- Volume of Solid
Name the lab equipment you are using.
Solid objects have a volume (basically the
amount of space the object takes up). For
symmetrical objects, volume is simply
LENGTH X WIDTH X HEIGHT. Use a metric
ruler to measure the tin box at your station.
Make sure you have the right units.
You can also measure the volume of a
hollow object by filling it with water and
then measuring the volume of water inside.
Carefully fill the box with water and then
dump it into a graduated cylinder and
measure the volume.
CLEAN UP: Pour the water from the
graduated cylinder back into the beaker so
the next person can complete this station.
Station 2- Density
Name the pieces of lab equipment you are
using. Density is the mass per unit volume.
First, you need to mass the object
(magnifying cube). Make sure you tare
(zero) before massing it. Then, you need to
calculate the volume of an object, so
LENGTH X WIDTH X HEIGHT. Then you
divide the mass by the volume to calculate
the density. Make sure you have the right
units.
Station 3- Volume of a Liquid
There are three graduated cylinders in front
of you. Accurately measure the volume of
liquid in each. Don’t forget units.
Station 4-Measuring Volume Accurately.
Pour 25 mL of water into the 50 mL beaker
using the water in the 250 mL beaker. Then
pour the 25 mL of water into the graduated
cylinder. Record the measurement. Try
again to measure 25 mL in the beaker and
re-measure in the graduated cylinder.
CLEAN UP: Pour any water you used from
the graduated cylinder back into the 250 mL
beaker so the next person can complete
this station.
Station 5- Water Displacement
For irregular shaped objects, using a water
displacement technique can determine the
volume. Fill a graduated cylinder to
approximately 40 mL using the water in the
500 mL beaker. Record the EXACT volume of
the water. DO NOT ROUND!!!
Find the volume of the rubber stopper by
adding it to the graduated cylinder with the
water in it and re-measuring the volume. Then
calculate the volume of the stopper by
subtracting the initial volume (Vi) from the final
volume (Vf).
CLEAN UP: Pour any water from the graduated
cylinder back into the 500 mL beaker so the
next person can complete this station. Take
the rubber stopper out of the graduated
cylinder…DO NOT LEAVE THE STOPPER IN THE
CYLINDER, PLEASE!
Station 6- Temperature
Name the lab equipment you are using.
Determine the temperature of each beaker
of water using the SAME digital
thermometer. Turn on the thermometer
and remove the protective cap before
measuring. Then average all three
temperatures to find the mean
temperature of the water in all three
beakers. The find the average simply add
all three temperatures together and divide
by the total number of temperatures.
CLEAN UP: Take the thermometer out of
the beakers of water and replace the
protective caps back on the thermometer.
Turn off the thermometer as well.
Station 7- Mass
Name the lab equipment you are using.
Determine the mass of spoonful of NaCl
(table salt). Do not forget to use a weigh
boat and tare (zero) the electronic balance.
CLEAN UP: Pour the salt from the weigh
boat into the “WASTE” beaker once you are
finished.
Repeat the above directions for a spoonful
of C24H22O11 (sucrose; table sugar).
Station 8- Temperature
Measure the beaker of water using the
alcohol thermometer. Repeat using the
digital thermometer. Turn on the digital
thermometer and remove the protective
cap before measuring.
CLEAN UP: Take all thermometers out of
the beakers of water and replace the
protective caps back on the thermometer.
Turn off the thermometer as well.
Station 8- Length of Objects
Measure all of the items in the table on
your handout using the ruler or meter stick
at your station (desk).
