Measuring
What is matter?
Rigid (keeps its own shape, not easily changed)
Fixed volume
Fixed shape
What is a solid?
How something feels (smooth, rough, soft, bumpy)
When a substance changes how it looks but not what it is made up of
What is a physical change?
The amount of matter something has
Not rigid (flows)

Non fixed shape (takes the shape of the container it is in)

What is solubility?
How closely packed particles are to each other
What is density?
Which state of matter particles have the most kinetic energy?
Gas particles
If something can be pushed or pulled with a magnet
What is magnetism?
Matter cannot be created or destroyed
Law of conservation of mass
