is the amount of matter an object has. We often use a triple-balance beam to measure
balance gets its name because it has three beams that allow you to move known
masses along the beam.
is a picture of a triple beam balance. You probably have used one in school.
There are also many other types of balances. Scientists
need balances that can measure very small amounts of mass.
you are using a triple beam balance in school you might want to brush up on your
skills on how
to use a triple-beam balance
Because a triple beam
balance compares a known mass to an unknown mass it is unaffected by gravity.
Unlike a spring scale which really measures weight, the triple beam balance gives
a true measure of mass.
Do you often get confused between
mass and weight? Check

it's time to practice your skills using the triple-beam balance.
A block is put onto a triple beam balance.
is the mass of the object (to the closest tenth of a gram)?
Remember to find the mass using a triple beam balance you must add the mass values
of each of the three beams.
