States of Matter

4. Remember…the basic particle is an ATOM
Atoms are amazing! They are the smallest particle known to exist.
BUT – how these tiny particles move totally affects the structure of matter!
When there is change in matter it is a PHYSCIAL CHANGE 4

5. 1st state of matter: Solid
Particles Arrangement- tightly packed
Particle Motion- vibrate
Energy- Slow
Volume- Definite (fixed)
Shape-Definite (fixed)
Density-High except for water (it has medium density)
Structure- crystalline

6. 2nd State of Matter: Liquid
Particles Arrangement- close
Particle Motion- slide past one another
Energy- Medium
Volume- Definite
Shape- Indefinite
Density-Medium except for water (it has high density)

7. 3rd State of Matter: Gas Particles Arrangement- Far apart
Particle Motion- fast and move in all directions
Energy- High
Volume- Indefinite
Shape- Indefinite
Density- Low

8. Stand Up and Show the states of matter
Solid- Stand 1 foot away from your classmates and shake
Liquid- Slide slowly past one another, but don’t get too far away
Gas- WALK past one another, move in all directions
