<strong>Metric</strong> <strong>Measurement</strong> <strong>Lab</strong><br />

Background: The efficiency and effectiveness of the metric system has long been evident to<br />

scientists, engineers, and educators. This lab will enable you to develop an appreciation of the<br />

efficiency of the metric system and the ability to take measurements using this system. In order<br />

to understand completely the usage of the <strong>Metric</strong> System, you need to be familiar with the<br />

history of how the system came into being and with the conversion factors.<br />

Objective: In this investigation, you will learn how to accurately measure length, volume,<br />

temperature and mass using scientific equipment.<br />

Materials:<br />

water<br />

foam block<br />

2 beakers metric ruler<br />

graduated cylinder<br />

triple beam balance<br />

2 Celsius thermometers clock<br />

ice cubes<br />

marble<br />

stirring rod<br />

calculator<br />

Experimental Procedure:<br />

Note: be sure to use the proper units for all answers recorded on the Data Tables.<br />

1. Complete length, mass, volume and density measurements using metric instruments.<br />

a. using a metric ruler, measure the length, width and height of a foam block.<br />

Express your answer to the nearest 0.10 of a cm. Record you answer in Data Table 1.<br />

b. using your measurements of the block, calculate the volume of the block. Express<br />

your answer to the nearest 0.10 of a cubic-centimeter (cm3).<br />

Record your answer in Data Table 1.<br />

c. using the triple-beam balance, determine the mass of the block. Express your answer<br />

to the nearest 0.10 of a gram. Record your answer in Data Table 1.<br />

d. using your found values of volume and mass, calculate the density of the block.<br />

Record your answer in Data Table 1.<br />

Density is calculated as Mass divided by Volume. (D=M/V)<br />

2. Measure the volume of a liquid. Note: you may need to use the “over-flow” beaker in the<br />

event the amount of liquid exceeds the capacity of the graduated cylinder.<br />

a. pour the water from beaker “A” into the graduated cylinder.<br />

b. measure the amount of water in the graduated cylinder. To accurately measure the<br />

volume, your eye must be at the same level as the bottom of the meniscus.<br />

The meniscus is the curved surface of a column of liquid.<br />

Record your answer in Data Table 2.<br />

c. repeat steps a and b for beaker “B.”

3. Determine the volume of a solid object using displacement.<br />

a. fill the graduated cylinder up to around 50 ml with water.<br />

b. record your marble color and exact volume in Data Table 3.<br />

c. place the marble into the graduated cylinder by sliding it down slowly.<br />

Determine the volume of the marble and water. Record your answer in Data Table 3.<br />

d. determine the volume of the marble. Record your answer in Data Table 3.<br />

4. Measure the temperature of a liquid.<br />

a. fill beaker “A” and beaker “B” with exactly 100 ml of water.<br />

Record this volume in Data Table 4.<br />

b. place a thermometer in each beaker. Wait 2 (two) minutes and then record the<br />

temperature of the water in each beaker in Data Table 5.<br />

c. carefully add 3 (three) ice cubes to the water in beaker “B.” DO NOT STIR.<br />

d. after 1 (one) minute, observe the temperature of the water in each beaker.<br />

Record the temperatures in Data Table 5.<br />

e. after 5 (five) minutes, observe the temperature of the water in each beaker.<br />

Record the temperatures in Data Table 5.<br />

f. find the volume of water in beaker “A.” Record the volume in Data Table 4.<br />

g. Stir the water and ice in beaker “B.”<br />

Continue to stir until the ice has been melted completely.<br />

After the ice in beaker “B” has melted, find the volume of water and record the<br />

volume in Data Table 4.<br />

3. Did the temperature of the water in beakers A and B change during the investigation<br />

Explain. ___________________________________________________________________<br />

4. Was there a difference in the volume of water in the beakers at the end of the investigation<br />

Explain. ___________________________________________________________________<br />

5. Of the following graduated cylinders, 100 ml, 25ml, or 10ml; which would you use to<br />

accurately measure 8 ml of a liquid Explain.<br />

6. Using a Celsius thermometer, how would you determine the temperature of the classroom<br />

Would you change your procedure if you were using a Fahrenheit thermometer Explain.<br />

__________________________________________________________________________<br />

7. When ice was added to beaker B, the thermometer was not removed. Explain why.<br />

__________________________________________________________________________<br />

8. Suppose the water in beaker B had been stirred after the ice had been added. What would be<br />

the effect of this on the temperature of the water Does stirring have an effect on the final<br />

temperature of the water Explain.<br />

9. Why do you think the water in the graduated cylinder forms a meniscus<br />

__________________________________________________________________________<br />

10. Evaporation is sometimes described as a cooling process. This is because as a liquid<br />

evaporates it takes heat from the surroundings. Using water, two Celsius thermometers, a<br />

small piece of gauze and some thread, design an investigation to test the statement.<br />

Indicate the control and the variable; include problem, hypothesis, procedure, and your<br />

expected observations and conclusions.<br />

ANALYSIS QUESTIONS - ANSWERS<br />

1. What is the largest volume that your graduated cylinder is able to measure<br />

LARGE CYLINDER =100 mL<br />

SMALL CYLINDER =25 mL<br />

2. What is the smallest volume of a liquid that your graduated cylinder is able to measure<br />

LARGE CYLINDER =1.0 mL<br />

SMALL CYLINDER =.5 mL<br />

3. Did the temperature of the water in beakers A and B change during the investigation<br />

YES, THE TEMPERATURE IN BEAKER “B” WAS COLDER.<br />

4. Was there a difference in the volume of water in the beakers at the end of the investigation<br />

Explain. YES, THE VOLUME IN BEAKER “B” WAS LARGER.<br />

5. Of the following graduated cylinders, 100 ml, 25ml, or 10ml; which would you use to<br />

accurately measure 8 ml of a liquid Explain.<br />

10 mL - THE 10 mL CYLINDER WILL BE CALIBRATED TO A SMALLER SCALE SO<br />

THAT IT WOULD BE ABLE TO GIVE YOU A MORE ACCURATE MEASUREMENT.<br />

6. Using a Celsius thermometer, how would you determine the temperature of the classroom<br />

Would you change your procedure if you were using a Fahrenheit thermometer Explain.<br />

LEAVE THE THERMOMETER IN THE ROOM LONG ENOUGH TO ALLOW THE<br />

THERMOMETER TO ADJUST, THEN I WOULD READ THE TEMPERATURE<br />

FROM THE THERMOMETER. NO, I WOULD NOT CHANGE THE PROCEDURE.<br />

THE ONLY DIFFERENCE WOULD BE THE SCALE IN WHICH THE<br />

TEMPERATURE WAS READ.<br />

7. When ice was added to beaker B, the thermometer was not removed. Explain why.<br />

SO THE TEMPERATURE COULD BE MONITORED AS THE ICE MELTED.<br />

8. Suppose the water in beaker B had been stirred after the ice had been added. What would be<br />

the effect of this on the temperature of the water Does stirring have an effect on the final<br />

temperature of the water Explain.<br />

THE STIRRING OF THE WATER WOULD DISTRIBUTE THE COLDNESS EVENLY<br />

THROUGHOUT THE WATER. YES, BECAUSE THE MELTED ICE WATER IS MUCH<br />

COLDER THAN THE TAP WATER USED IN BEAKER”A”.<br />

9. Why do you think the water in the graduated cylinder forms a meniscus<br />

THE WATER MOLECULES ARE ATTRACTED TO THE WALLS OF THE CYLINDER.

10. Evaporation is sometimes described as a cooling process. This is because as a liquid<br />

evaporates it takes heat from the surroundings. Using water, two Celsius thermometers, a<br />

small piece of gauze and some thread, design an investigation to test the statement.<br />

Indicate the control and the variable; include problem, hypothesis, procedure, and your<br />

expected observations and conclusions.<br />

PROBLEM:<br />

Design an investigation to test the statement that evaporation is a cooling process.<br />

HYPOTHESIS:<br />

If water is allowed to evaporate from the bulb of a thermometer, then the<br />

temperature reading on the thermometer will decrease.<br />

PROCEDURE:<br />

! 1. Obtain 2 celsius thermometers to be used in the investigation.<br />

! 2. Place thermometer “A” on the table and record the temperature in 0 C<br />

! 3. Place gauze around the bulb of thermometer “B” and tie it in place.<br />

! 4. Soak the gauze in water and fan the gauze to cause the evaporation of the water.<br />

! 5. Record the temperatures of both thermometers “A” and “B” every minute for 10 minutes.<br />

CONTROL:<br />

Thermometer “A” with no gauze and water.<br />

VARIABLE:<br />

Thermometer “B” with the gauze and water.<br />

OBSERVATIONS:<br />

Over time, the temperature readings of thermometer “B” will be cooler than the<br />

temperature of thermometer “A”.<br />

CONCLUSIONS:<br />

Evaporation of water from a surface does cause a cooling effect on the surface from<br />

which the water evaporates from.
