Solid Liquid Gas
Clay, Rock, Ice tray, Plastic, Sponge/foam, magnifying glass, flour, foil
Water, oil, corn syrup??, air freshener??, Hand sanitizer
Air in balloonAir freshener (evaporated)
Usually firm surfaceHas a “shape”Things usually do not pass through
Flows easier than solid, things can usually go through itUsually spreadsHas no set shape
Usually harder to see, Spreads out

State of Matter: the physical form that matter is in
based on the position and movement/energy of the atoms and molecules in that substance.
4 states: *solids, *liquids, *gases, plasma
Solids
Atoms movement and energy: atoms/molecules in a solid do not move a lot. (vibrate). Low energy
Next >
Shape-shifting ability: solids keep the same shape no matter what container they are in.
Volume: solids take up the same amount of space no matter whatcontainer they are in.
Inquiry: How are solids, liquids, and gases different?
Liquids (intermediate stage between solids and gases)
Atoms movement and energy: Atoms/molecules in a liquid move around more freely than in a solid. (Medium energy)

Volume description: Gas can be compressed to change the amount of space they take up. (no set volume)
Atoms movement and energy: Atoms/molecules in a gas move around quickly. (High energy)

Inquiry: What is the difference between solids, liquids and gases?
All matter possesses a certain amount of energy because atoms/molecules are always moving.
Solid Liquid GasTemperature measures the amount of motion/energy, and heat in an object.
(measured in Celsius (oC), Fahrenheit (oF), or Kelvin

Inquiry: What is the difference between solids, liquids and gases?
Matter: anything that takes up space. (made up of atoms/molecules)
Solid Liquid GasStates of Matter: different phase of matter based on the amount of energy the atoms have.
Inquiry: What are the different phase changes of matter?
Melting: solid to liquid.Melting point: the temperature at which a solid
turns into a liquid. (waters melting point = above OoC or 32oF)
Solid Liquid
Increasing temperature, atoms movement and energy.
Temperature measures the amount of motion/energy, and heat in an object. (measured in Celsius (oC), Fahrenheit (oF), or Kelvin
Freezing: liquid to solidFreezing point: the temperature at which a liquid
turns into a solid. (waters freezing point = 0oC or 32oF)
Liquid Solid
Decreasing temperature, atoms movement and energy.
Inquiry: What are the different phase changes of matter?
*Evaporation: liquid to gas*Boiling point: the temperature at which a liquid
turns into a gas. (waters boiling point = 100oC or 212oF)
Liquid Gas
Increasing temperature, atoms movement and energy.
Inquiry: What are the different phase changes of matter?
*Condensation (con-den-say-shun): gas to liquid
Gas Liquid
Decreasing temperature, atoms movement and energy.
Inquiry: What are the different phase changes of matter?
Sublimation(sub-li-ma-shun): solid to gas (skips over liquid stage)

Inquiry: How do phase changes influence the water cycle?
Inquiry: What happens to the temperature of a substance during a phase change?
Phase Change: a physical change, when a substance changes its state of matter.
Ex. At boiling point, a phase change occurs from liquid to gas.
The temperature at which water becomes a gas (steam) is 100° C or 212oF. Boiling points of other
liquids may be much higher or lower than this.Next >

Inquiry: What happens to the temperature of a substance during a phase change?The melting point of a substance is one of its
most important properties.
This is the temperature at which a substance turns from a solid into a liquid.
The melting point of ice is above 0° C or 32oF. This means that water is a liquid at room temperature (20° C). Next

Which graph best represents the relative distance between the particles of most substances in their solid,
liquid and gas states?
Solids = atoms are close and low energyLiquids = atoms are further apart, moving at “medium” energyGases = atoms are spread out, and moving rapidly, “high” energy
2) Develop a model to show the relationship between heat energy and the motion and position of particles in a sample of matter. Use a group of 20 students in
an empty room to represent the particles in the following samples of matter.
a) Students represent a “solid”:
b) Students represent a “heated solid”:
c) Students represent a “liquid”:
d) Students represent a “gas”:
Students should go stay close together and shake alittle.
Students should move apart alittle and shake
more.Students should
separate and walk a around the
classStudents should spread out and run around the room
