Measuring and science
equipment
Using a balance
Object to be
measured
goes on the
left side
If you
need to
add more
mass,
place
masses on
the right
side.
Move the sliding masses until the needle lines up. Be sure
to look at it straight on.
Add the two scales together.
What would this mass be?
A gram (g) is a unit of mass equal to
about a small paperclip.
There are 1000g in a kilogram.
That’s a lot of
paper clips!!!
A kilogram (kg) is used to measure
larger masses. A kilogram is a unit
of mass equal to 1,000 g, which is
about the mass of a cantaloupe.
Volume
• Use a graduated cylinder.
• Measures in milliliters
• 1000 milliliters is 1 Liter
• Always read at eye level.
Water in a glass graduated
cylinder forms a meniscus. The
water forms a sort of curve at
the surface
Meniscus- always
read from the
lowest point on
the meniscus.
Length
Centimeters
millimeters
A kilometer would be 1000 meters.
