1. Scientific Measurement
Measuring Mass, Volume, and Length

2. Measuring Volume

3. What is Volume? Volume is the amount of space an object takes up.
The base unit of volume is the LITER.
Abbreviated L
Example: a Coke comes in 2L bottles
Most often you will use milliliters (mL) when measuring liquids and cubic centimeters (cm3) when measuring solids.
1 L = 1000mL
1mL = 1cm3
1cm3 = ____ L?

4. Measuring Volume - Liquids
Read the measurement based on the bottom of the meniscus or curve.
When using a real cylinder, make sure you are eye-level with the level of the liquid.
Tool: Graduated Cylinder
What is the measurement of this graduated cylinder?

Reading the Meniscus

6. Measuring Volume of Regular & Irregular Shapes
TASK: Measure the volume of your cubes using 2 different methods of determining volume.
TAKE 1 MINUTE OF PRIVATE THINK TIME TO GATHER YOUR THOUGHTS.
Discuss for 2 minutes with your group!
In your group, decide how you will determine the volume of each cube utilizing at least 2 different methods.
Write a procedure for your task. Get Mrs. Oliver to sign off on it.
Create a data table to record your volumes.
Perform your experiment.

7. Measuring Volume - Regular Solids
Volume = L x W x H
We can measure the volume of regular object using the formula length x width x height.
V = ____ cm x ____cm x ____cm = ____cm3
Height
Width
Length

8. Measuring Volume - Irregular Solids
The Displacement Method
The water displacement method is the process of measuring the volume of an irregularly shaped object by immersing it in water.
This method served as the basis for the principle developed by the Greek philosopher Archimedes.
Determine the volume of the hammer:
Amount of H2O with object = ______
About of H2O without object = ______
Difference = Volume = ______

9. Measuring Length

10. Millimeter (mm) - Centimeter (cm)
What is Length?
Length is the measurement of the distance between two points
The unit of length depends on the object being measured and what measurement system you are using:
ENGLISH UNITS
METRIC UNITS
Inches (in) - Feet (ft)
Millimeter (mm) - Centimeter (cm)
Yard (yd)
Meter (m)
Mile (mi)
Kilometer (km)
1 yard = meters
1.6 kilometers
1 mile

11. Measuring Length 1 kilometer = 1000 meters 1 meter = 100 centimeters
Important units:
1 kilometer = 1000 meters
1 meter = 100 centimeters
1 centimeter = 10 millimeters
Measuring Length
Tool: Ruler
Begin reading the ruler at the 0 mark, (Note: this is not always the end of the ruler)
Ruler:

12. Measuring Mass

13. Mass Mass is the amount of matter in an object
Mass is not the same as weight
Weight may change as gravity changes, mass does not
The base unit of mass is the GRAM
Abbreviated g
Example: a paper clip has a mass of 1 g

14. Measuring Mass Use a tool called a BALANCE
Triple-Beam Balance or Digital Balance

15. Reading a Triple Beam Balance
Read the 100s bar first
Add the 10s bar
Then the 1s bar
Any “little lines” between the 1s are equal to 0.1 g

16. Using a Balance
