Step #1
Clean the pan.
Step #2If the pointer is not
at zero, have the teacher zero the
balance.
Step #3Place an object in the center of
the pan.
Step #4Move the middle rider over a notch until the pointer drops. Then
move it back one notch.
Step #5Repeat the
previous step with the back rider.
Step #6Move the front
rider over until the pointer is at zero.
Step #7Add the values of the three beams to
determine the mass.
There will always be two decimal places in your answer. The last
one must always end in a 0 or a 5.
