What state of matter keeps its shape?
A solid is the state of matter that keeps its shape.
liquid

liq uid
The state of matter that takes the shape of its container and takes up a definite amount of space
What is a state of matter?
A state of matter is the arrangement of particles.
solubility

sol u bil i ty
A measure of the amount of material that will disolve in another material.
Which states of matter take the shapes of their containers?
Liquids and gases are states of matter that take the shape of their containers.
gas

.
The state of matter that has no definite shape and takes up no definite amount of space.
What is a solution?
A solution is a mixture in which particles of different kinds of matter are mixed evenly together.
matter

matt er

Everything in the universe that has mass and takes up space.
What makes the particles in matter move faster?
Heating matter make its particles move faster.

Example: When ice is heated, some particles begin to move fast enough to break away from
their neighbors. As regular arrangement of particles breakdown, the ice melts. Heated particles of liquid water move faster and faster. After a while they move fast enough to bounce away from each other and change to gas.
dissolve

dis solve
To form a solution with another material.
1 cm = 1 ml
.
mass

.
The amount of matter something contains
How are particles arranged in a solid?
The particles in a solid are close together, like neat and even stacks of tiny balls.

Ms. Noonan, 4th Grade
.
A boat made from matter that is denser than water can float on water if it is filled with enough _________.
air
solution

so lu tion
A mixture in which particles of different kinds of matter are mixed evenly with each other and do not settle out.
What are the three states of matter?
The three states of matter are:

- solid
- liquid and
- gas.
solid

sol id
Matter that has a definite shape and takes up a definite amount of space.
How are particles arranged in a liquid?
Particles of a liquid slip and slide around each other. The particles move from place to place, but they stay close to each other.
volume

vol ume
The amount of space that matter takes up.
What is density?
The property of matter that compares the amount of matter to the space taken up is called density.

- Gas is low density.
- A brick is higher density.
buoyancy

buoy an cy
The ability of matter to float in a liquid or gas.
How do you calculate the density of an object?
Find the density of a object by dividing its mass by its volume.
density

den si ty
The property of matter that compares the amount of matter to the space it takes up
A __________ has a definite shape.
solid
What changes happen to sugar when it dissolves in water?
.
Why does liquid have the same shape as its container?
The solid walls of the container don't change shape.
The particles of the liquid can't move past the walls, and the liquid particles stay close together. So, the liquid takes the shape of the container.
Describe matter.
Matter has mass and volume.
- Mass is the amount of matter in an object.
- The space that matter takes up is called volume.
- Density compares the amount of matter in an object to the amount of space it takes up.
What are particles?
- Particles are what mass is made of.
- Particles are so small they can only been seen by microscopes.
- Particles are always moving quickly.
- The arrangement of particles give matter properties.
_________________ is a measure of whether an object floats or sinks in a gas or liquid.
Buoyancy
The volume of a ____________ depends on the size of its container.
gas
Name the state of matter...

Particles slide past each other.
Liquid
In a ________________, the particles are far away from each other and move quickly.
gas
If the black ball is denser than a white ball of the same size, the black ball has ....
more matter taking up the same space.
Does the amount of matter in a liquid change when you pour it into another container?
No, if you pour a liquid from one container to another, the amount of matter in the liquid stays the same. The amount of space the liquid takes up also stays the same.
Review infer.
.
What is solubility?
Solubility is a measurement of the amount of a material that will dissolve in another material.
When matter is in the __________ state, its particles can slip and slide past each other.
liquid
How much space does a gas take up?
- The amount of space a gas takes up depends on the amount of space in its container.

- A gas always fills the container it is in.

- If the container is opened, the gas particles move out.
_____________ is anything that takes up space and has mass.
Matter
What is a gas?
A gas is matter that has no definite shape and takes up no definite amount of space.

- Particles in gases are not arranged in any way.

- Particles in gases move faster than particles in liquids.
Name the state of matter...

Particles stay near their
neighbor.
Liquid
____________ is a measure of the amount of a material that will dissolve in another material.
solubility
What happens when a material dissolves?
When one material forms a solution with another material,it dissolves.
What happens to a solid when it forms a solution with water?
- The solid dissolves in solution.

- The solid particles become evenly spread with the liquid particles.
What is buoyancy?
The ability of matter to float in a liquid or gas is called buoyancy.
How do you calculate the density of an object?
Find the density of a object by dividing its mass by its volume.
What word is used to describe the amount of space that matter takes up?
volume
What is an object with standard mass?
An object with standard mass is an object that the mass is known.

Scientists use a pan balance and standard masses to determine the mass of another object by adding or removing standard masses until the standard mass equals the mass of the object.
Air and pine wood each have a ____________ that is less than that of water.
density
Name the state of matter...

Particles are arranged in a pattern.
Solid
What property of matter compares the amount of matter to the space the matter takes up?
density
When the particles of a mixture are evenly mixed and can't be seen, the mixture is a ______________.
solution.
Name the state of matter...

Particles bounce away from each other.
Gas
How are particles in gases arranged?
- Particles in gases are not arranged.
- They do not stay close together.
- This is because the particles are moving so quickly.
What is a solid?
A solid is matter that has a definite shape and takes up a definite amount of space.

- The particles of a solid are close together, like neat and even stacks of tiny balls.

- Each particle moves back and forth around one point, this gives a solid its definite shape.
