Mass


Mass is the amount of matter an object has. We often use a triple-balance beam to measure mass.


A triple-beam balance gets its name because it has three beams that allow you to move known masses along the beam.

Here is a picture of a triple beam balance. You probably have used one in school. To read more about the triple-beam balances shown above click here


There are also many other types of balances. Scientists need balances that can measure very small amounts of mass.

If 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


Now it's time to practice your skills using the triple-beam balance.
