• In the kitchen, you might find three
different forms of water. What are
these three forms of water, and where
exactly in the kitchen would you find
them? Further, how do you use water
in each of these forms?
MYP Unit Question: How can such a small thing impact our environment in such a big way? Area Of Interaction: Environment Learner Profile: Inquirer, Knowledgeable, Communicators Essential Question: How do we describe the movement of particles in solids, liquids, gases, and plasmas states? Standard: Students will examine the scientific view of the nature of
matter. c. Describe the movement of particles in solids, liquids, gases,
and plasmas states. Learning Target: Today I am learning about the particle movements in
the different states of matter. This is important so that I can describe the difference between the states of matter according to their shape and particle.
Homework: Identify 10 items in your home that can be classified as a solid, liquid, or a gas.

Work session- Ian pg. 22 Separate your paper into three equal horizontal parts.
You will be given a copy of an article that discusses the different states of matter.
After you have read the article, use the grid that you created to create a picture that describes how the particles in the three states of matter interact.
One state of matter per section
Provide key details in each section.
STATES OF MATTER
Based upon particle arrangement
Based upon energy of particles
Based upon distance between particles
STATES OF MATTER
SOLIDS •Particles of solids are
tightly packed, vibrating
about a fixed position.
•Solids have a definite
shape and a definite
volume. Heat
Examples
STATES OF MATTER
LIQUID
Particles of liquids are
tightly packed, but are far
enough apart to slide over
one another.
Liquids have an indefinite
shape and a definite
volume.
Heat
Examples
STATES OF MATTER
GAS
Particles of gases are
very far apart and
move freely.
Gases have an
indefinite shape and
an indefinite volume.
Heat
Examples
PHASE CHANGES
Description of Phase Change
Term for Phase Change Heat Movement During
Phase Change
Solid to liquid
Melting Heat goes into the solid as it melts.
Liquid to solid
Freezing Heat leaves the liquid as it freezes.
PHASE CHANGES
Description of Phase Change
Term for Phase Change Heat Movement During
Phase Change
Liquid to gas
Vaporization, which includes boiling and evaporation
Heat goes into the liquid as it vaporizes.
Gas to liquid Condensation Heat leaves the gas as it condenses.
Solid to gas Sublimation Heat goes into the solid as it sublimates.
But what happens if you raise the
temperature to super-high levels…
between
1000°C and 1,000,000,000°C ?
Will everything
just be a gas?
STATES OF MATTER
PLASMA
Plasma, the 4th state of matter, it only happens at very high temperatures.
Plasma is a lot like a gas, except for the fact that electrons get stripped from neutral atoms of the element.
It does not occur naturally on Earth, but can be found in neon signs, fluorescent lights, plasma tv's, and lightening.
• Plasma is the
most common
state of matter
found in the
universe
Some places where plasmas are found…
1. Flames
2. Lightning
The Sun is an example of a star in its
plasma state
STATES OF MATTER
SOLID LIQUID GAS PLASMA
Tightly packed, in
a regular pattern
Vibrate, but do not
move from place
to place
Close together
with no regular
arrangement.
Vibrate, move
about, and slide
past each other
Well separated
with no regular
arrangement.
Vibrate and move
freely at high
speeds
Has no definite
volume or shape
and is composed
of electrical
charged particles
Closing- Ticket out the Door Identify the following on a sticky
post it and place on the wall on the way out.
A. Particles move about FREELY in space
B. Particles are packed TIGHTLY but slide over one another
C. Particles packed TIGHTLY and vibrate in a fixed position
