How would
you describe the movement of these particles?

How would
you describe the speed of these particles?
Solid
Particles vibrate in
place and are tightly packed
Slow
Can we act this out?
Slide5We can look at these 3 properties to figure out which state of matter an object is:
SHAPE
… d
oes
it
have a definite shape
?
MASS
…
does it have a definite amount of matter?
VOLUME
…
does
it take up a definite amount of space?

Slide8Let’s explore liquids…
Question to investigate
Does water hold together well or come apart easily?Materials for each groupWater in small cup, dropper, popsicle stick, index card
Procedure
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
e
nd of the dropper without it falling.
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.
Use a popsicle stick to slowly move your drop around the index card. Try to separate your drop into two.Use your popsicle stick to move the two drops near each other. Then move one drop so that the two drops touch.
Slide9What 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?

Slide12Because liquid molecules can move, they will take the shape of their container.

Slide16A gas will spread out to fill all the space in whatever container it is in.
Slide17If unconfined, gases will spread out indefinitely.

Slide19Solid
Tightly- packed
Liquid
closely- packed
Gas
loosely- packed
Solids:
A state of matter where the
p
articles
only vibrate and cannot move from their position
Liquids:
A state of matter where the particles move enough to slide past each otherGases: A state of matter where the particles bounce freely and rapidlySolid, Liquid, Gas animation

Slide23State
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.
