mass
an arrangement of elements based on their properties
Periodic table
anything that takes up space and has mass
matter
matter that has only one kind of atom
element
the amount of space matter takes up
volume
one of the tiny particles that make up all of matter
atom
a measure of the amount of matter in a certain amount of space
Density
something about matter that you can observe with one or more of your senses
property
what are the states of matter
solid, liquid and gas
the force per unit area that is applied to a substance
Pressure
force exerted on an object that is immersed in a gas or liquid that tends to float
Buoyancy
if an object sinks when in water, what is the density of that object.
greater than water
if you use air to pump up a ball, what state of matter is being used
gas
if an object floats in water that is the density of that object
lower density than water

how many elements does a chunk of gold have
one, gold
the greater buoyancy an object has, means what when immersed in water
it will float
what happens to the shape and volume when you pour water from a square glass to a tall, cylinder glass.
changes shape but the volume stays the same
