We can look at these 3 properties to figure out which state of matter an object is:
SHAPE … does it have a definite shape?
MASS … does it have a definite amount of matter?
VOLUME … does it take up a definite amount of space?

Examples of Solids
Let’s explore liquids…Question to investigate
Does water hold together well or come apart easily?
Materials for each group
Water in small cup, dropper, popsicle stick, index card
Procedure
1. Use a dropper to gently squeeze out one drop of water but try not to let the drop fall completely out of the dropper. See how far you can make the drop hang off the end of the dropper without it falling.
2. Place 4-5 drops of water into a small puddle on your index card. Gently tilt the index card in different directions so that the drop moves.
3. Use a popsicle stick to slowly move your drop around the index card. Try to separate your drop into two.
4. Use your popsicle stick to move the two drops near each other. Then move one drop so that the two drops touch.
What did you observe?
When you squeezed the drop of water out of the dropper, did the water break apart or hold together?
When you were pulling the drop around the wax paper, did the water seem to hold together or come apart easily?
Was it easy or difficult to make the drops come together?
How would you describe the motion and attraction of the liquid molecules?
Phase Motion of ParticlesHow would you describe the
movement of these particles?
Speed of ParticlesHow would you describe the speed
of these particles?
Liquid Particles are close, but can slide past one another

Because liquid molecules can move, they will take the shape of their container.

Gas Particles are constantly expanding and far apart

A gas will spread out to fill all the space in whatever container it is in.
If unconfined, gases will spread out indefinitely.
Examples of Gases
Solid Tightly- packed
Liquidclosely- packed
Gasloosely- packed
o Solids: A state of matter where the particles only vibrate and cannot move from
their position
o Liquids: A state of matter where the particles move enough to slide past each
other
o Gases: A state of matter where the particles bounce freely and rapidlySolid, Liquid, Gas animation

State of matter: one of the forms that matter takes, such as solid, liquid, or gas. Solid: matter that has a fixed volume and a fixed shape. Liquid: matter that has a fixed volume but not a fixed shape.Gas: matter that has no fixed volume or fixed shape.
Guided Video NotesThe following two slides are video notes that go with two videos on DiscoveryEducation.com
You must have an account to access these videos, but many school systems purchase accounts, so be sure to check if you aren’t sure.
The titles of the videos are:
1. “Properties of Matter, Part 1” (20:28)
2. “Properties of Matter, Part 2: Liquids, Solids, and Gases” (17:00)
I run the sheets front to back to save paper!
