1. What are mass,
volume, and density?

2. Mass
 Amount of matter in an object
Metric Unit of Mass = gram
Method of Measurement:
Electronic Balance
Triple Beam Balance
Double pan Balance

3. Volume
 Amount of space occupied by an object
Metric Unit of Volume = Liter or cm3
Method of Measurement:
Length x Width x Height
Liquid Displacement

4. Density
 Mass per unit volume
Metric Unit of Density = g/mL or g/cm3
Method of Measurement:
Use the formula: mass
volume

5. How can I measure volume by
displacement?
 Put a measured amount of water in a
graduated cylinder
 Drop in an irregular shaped object
 Note water level
Final water level (volume)
– Initial water level (volume)
= volume of irregular object

6. Reflection
We have spent several days learning about the Scientific Method
and Metric System of Measurement
In your binders write for me:
 1-2 Paragraphs about the Scientific Method: What did you
learn?, Is there something you don’t understand?, Are you
comfortable with the terms?
 1-2 Paragraphs about Metric Measurement: What did you
learn?, Is there something you don’t understand?, Why should
we know the Metric System of Measurement?
