2. Measuring Mass
Mass is a measurement of the amount of
matter in an object
Instrument: Balance (triple beam, double
pan or electronic)
Base unit: gram (g)
Other common units:
milligram (mg)
kilogram (kg)
Which is larger than a gram? Which is
smaller?
3. Measuring Distance
Distance is a measurement of how far apart
objects are from each other.
Instrument: Meter stick
Base unit: meter (m)
Other common units:
millimeter (mm)
centimeter (cm)
kilometer (km)
Which of the units are larger than a meter?
Which are smaller?
4. Measuring Liquid Volume
Volume is a measurement of the amount
of space an object or matter occupies
Instrument: graduated cylinder or
beaker
Which instrument will give you a more
accurate measurement?
Base unit: liter (L)
Other common unit:
milliliter (mL)
Is this smaller or larger than a liter?
5. Reading the Meniscus
When measuring liquid volume, you must
remember to read the meniscus properly
The meniscus is curve of a liquid when
placed in a cylinder
Always make your measurement at the
middle of the meniscus
What is the measurement in the
graduated cylinder?
6. Measuring Solid Volume
How do you measure the volume of an
object that has a regular shape, such as a
block of wood?
Instrument: meter stick
Formula: Volume = l x w x h
Base unit: cubic meter (m3
)
Other common unit:
cubic cm (cm3
)
Why is the unit cubed?
7. Measuring Solid Volume
Water Displacement Method
How do you measure the volume of an object that
has a irregular shape, such as a rock?
There are actually 2 methods, both involving
water.
Instrument: graduated cylinder or overflow can
Base unit: cubic meter (m3
)
Other common unit:
cubic cm (cm3
)
Which do you think is more accurate?
8. Measuring Weight
Weight is a measurement of the force
of gravity acting upon an object
Instrument: Spring scale
Base unit: Newton (N)
9. Measuring Temperature
Temperature is the measurement of the
energy of the molecules in an object
The higher the temperature, the faster the
molecules are moving
Instrument: thermometer
Base unit: degrees Celsius (o
C)
Other unit: Kelvin (K)
