It’s Everything!
Everything that you see is matter. Matter is anything that takes up space.
One way to describe matter is by its physical properties.
A physical property is a characteristic of matter that you can observe or measure directly.

A pan balance measures mass in grams (g).
To find mass, you often have to use math. Subtract the mass of the empty container from the mass of the container and its contents.

Measure It!
To find the volume of a solid using a graduated cylinder, you must measure and use math.
First find the volume of the water in the graduated cylinder. Then add the solid. Measure the volume again. Subtract the volume of the water alone from the volume of the water and the object.
The volume of a solid is measured in cubic centimeters. Remember that 1 milliliter equals 1 cubic centimeter.
