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.
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.

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.
