Matter

• The amount of matter in an object is its mass. You can use a pan balance to measure mass.



Matter

• Less massive objects are measured in grams (g). More massive objects are measured in kilograms (kg).



Volume!


• Volume is how much space an object takes up. Volume is measured in milliliters (mL).

• The beaker can be used to measure the volume of liquids.

for him, water was pushed out of the tub

“Displacement”







Don’t Be So Dense!


• Density is a physical property of matter. It is the amount of matter present in a certain volume of a substance.




• Density indicates how close together the particles in an object are.

• The density of a substance does not depend on how much matter is present.

• A small piece of eraser has the same density as a whole eraser.




• Objects less dense than water float.

• Objects more dense than water sink.


Sum up!
