Measuring Properties of Matter Lab
VOCABULARY REVIEW
Matter
Mass
Volume
Distance (length, height, width)
The amount of space between two objects
Tools to Measure Matter
ruler
digital scale tape measuregraduated cylinder
triple-beam balance
What about Units of Measure?
The International System of Units (SI)
also called Metric System (a base 10 system)
Fluids: liters
Distance: meters
Mass: grams
Temperature: Celsius or Kelvin
Prefixes: kilo, hecto, deca, deci, centi, milli, micro, etc.
English Customary Weights and Measures
also called US Customary Units
Fluids: ounce, cup, pint, quart, gallon
Distance: inch, feet, yard, mile
Mass: ounce, pound, ton
Temperature: Fahrenheit
In science, we use the metric system!
Remember how to find the volume of a regular object?
Volume = Length x Width x Height

Each table group will work together as a team
Take turns letting everyone measure (work cooperatively)
Each teams will visit six lab stations labeled A, B, C, D, E, and F.
Measuring Properties of Matter Lab
One team per station (if all stations are busy, sit back at your table and wait patiently)
Only bring your lab sheet and pencil to stations (make sure chairs are tucked in and items are out of walkways)
Use a quiet voice while completing the lab
Absolutely, no horse-play!
When you complete a station, put all materials back the way you found them (clean up)
When you finish, sit back at your table and discuss your results with team
Lab Procedures
There are two objects (Object A and Object B) located at this station.
Using the measurement tools located at this station, measure the length in the units required.
Station A
16. Record the length of object A in mm.
17. Record the length of object B in cm.
There are two objects (Object A and Object B) located at this station.
Using the measurement tools located at this station, measure the mass using metric units.
Station B
18. Record the mass of object A.
19. Record the mass of object B.
There are two beakers at this station that are filled with a colored liquid. They are labeled Liquid A and Liquid B.
Using the graduated cylinders, measure the volume of both liquids.
Be careful not to spill and make sure to put items back the way you found them (liquid in beakers, not cylinders)
Station C
20. Record the volume of the liquid A.
21. Record the volume of the liquid B.
There is only one object located at this station.
Using the measurement tools located at this station, find the mass and volume of this object.Hint: Volume = length x width x height
Station D
22. Record the mass of the object.
23. Record the volume of the object.
There is only one object (a colored liquid) located at this station.
Using the graduated cylinder located at this station, find the volume of this object. Be careful not to spill and make sure to put items back the way you found them (liquid in beakers, not cylinders)
Station E
24. Record the volume of the object.
There is only one object (a colored liquid) located at this station.
Using the graduated cylinder located at this station, you must measure exactly 100mL of the liquid in the graduated cylinder. Next, record the mass of this liquid in the graduated cylinder.
To find out the mass of just the liquid, you must then weight the emptied graduated cylinder and subtract this value from your initial value.
Hint: Mass(grad. cylinder with liquid) – Mass (grad. cylinder empty) = Mass of liquid
Be careful not to spill and make sure to put items back the way you found them (liquid in beakers, not cylinders)
Station F
25. Record the mass of 100mL of the liquid.
What are some mistakes that can be made when measuring mass?
Do all objects have the same amount of mass?
How did you measure length?
How did you measure mass?
How did you measure volume?
