WORDS TO KNOW AND MEASURE BY….
Matter-anything that has mass and takes up space.
- Everything we know of is composed of matter: our bodies, our surroundings, our planet, the water, the air, the moon, other planets…it goes on and on and on.
- The properties of light make it questionable as to whether it is matter or not (investigate if you want to know more).
- “Outer space” and “ideas” do not fit the definition of matter as they do not demonstrate inertia (Objects at rest/in motion stay at rest/in motion unless acted upon by an outside force.)
Mass– the amount of matter in an object.
- The mass of an object stays the same wherever the object is put.
- It is usually measured with a balance and is measured in units such as grams (g) and kilograms (kg).

Weight– the measure of the pull of gravity.
- This will change depending on the force of gravity. For example, if you go to a different planet your mass will stay the same but your weight will be different.
- So, weight matters on the amount of mass (which never changes) and the pulling force of gravity (which may change from place to place).
- Measured with a spring scale or a balance. Units are in newtons (N)
- Weights in other places:

Volume- the amount of space an object takes up.
- Formulas: For regular shaped objects, such as a rectangle or square, it can be determined by multiplying length x width x height (l x w x h). Units = cubic centimeters = cm^3. Other formulas for volume- http://www.factmonster.com/ipka/A0876212.html.
- For irregular shaped objects, volume is found by putting the object in a graduated cylinder and measuring how much the water rises. See this link for more specific descriptions: http://www.tutorvista.com/content/physics/physics-i/measurement-and-experimentation/measurement-volume.php
- Two objects can have the same volume but a different mass. It depends on what type of material the objects are made.
Density- measures how tightly the matter in an object is packed.
- Also defined as the mass of a unit volume of a substance.
- To find the density of an object you can use the formula: density = mass/volume.
