2. Mass (Definition)
• Mass- The amount of matter in an object.
• All things are made up of matter. Mass does not change with gravity.
• If you were to stand on top of Mt. Everest, your mass would stay the same.
Even though there is a gravitational pull in high places such as Mt. Everest,
you would weigh less but still remain the same mass.
3. 1st Way to Calculate Mass
• There are two different ways to measure Mass.
• The first way to measure mass is to use a balance scale. Sometimes
you won’t get the exact measure. You would have to guess the
hundredths or tenths. This one is a bit more complicated.
4. 2nd Way to Calculate Mass
• The second way to calculate mass is on an electric scale.
• This way is pretty simple. You turn the scale on and press the button
onto grams, then you press the zero button. That will reset it.
Finally, you can put your object on the scale!
5. Volume
• Volume-The amount of matter a three dimensional
object can contain or hold.
• Volume can be found in anything, from cardboard boxes
to building blocks. But it doesn’t have to be rectangular
prisms, it can be anything.
6. 1st Way to Calculate Volume
• The first way to calculate volume is to use a ruler, tape
measurer, or any other device that uses length(distance).
• Measuring the height, length, and width, you can
determine the volume of the object.
7. 2nd Way to Calculate Volume
• The second way to measure volume is to use water
displacement.
• For example, if you are measuring the volume of an irregular shape,
such as a 12-sided object, you fill the graduated cylinder or beaker
with water or any other liquid, preferably water. Then, you put in
the irregular shape into the beaker and you measure how much the
water rises (milliliters). Then you can express the volume of the
water displaced by the object in cubic centimeters.
