2. Vocabulary Review

3. Matter

4. Mass

5. Volume

6. Distance (length, height, width)

7. Tools to Measure Matter
triple-beam balance

8. What about Units of Measure?

9. English Customary Weights and Measures
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.
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!

10. Remember how to find the volume of a regular object?
Volume = Length x Width x Height

14. Measuring Properties of Matter Lab
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.

15. Lab Procedures
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

16. Station A
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.
16.
Record the length of object A in mm.
17.
Record the length of object B in cm.
Use unsharpened pencil and paperclip

17. Station B
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.
Object = cube of post-its? dice? toy car? rock?
18.
Record the mass of object A.
19.
Record the mass of object B.

18. Station C
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)
Color the liquid and pre-measure and then post measure (all students should be between your before & after measures)
20.
Record the volume of the liquid A.
21.
Record the volume of the liquid B.

19. Station D 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
Object = density cube or rubrik’s cube?
22.
Record the mass of the object.
23.
Record the volume of the object.

20. Station E
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)
Object = colored liquid in beaker (measured with graduated cylinder)
24.
Record the volume of the object.

21. Station F
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)
Object = colored saltwater in beaker (measured with graduated cylinder)
25.
Record the mass of 100mL of the liquid.

22. Reflection Questions
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?
