term for anything that takes up space and has mass

matter

the small bits of material that make up matter

particles

Look how the particles are arranged!

matter that has definite volume and takes the shape of its container

liquid

matter that has no definite shape and takes up no definite amount of space

gas

matter that has definite volume and shape

solid

Adding heat makes the particles act differently!

Adding Heat

They start moving

faster!!!!

amount of space that matter takes up

volume

VolumeVolume is the amount of space that matter takes up. The volume of something

can be measured using math and a graduated cylinder, a ruler, or a tape measure.

volume = Length X Width X Height

Think about these two methods for calculating a solid’s volume. Which one would be used to find

the volume of...

volume = Length X Width X Height

This method is better because it

is an irregular shape.

This one because it is a nice, straight shape that can easily be

measured with a ruler.

You can also measure the volume of a liquid using…

cotton balls white sand

Look at these containers. One is filled with cotton balls and one is filled with white sand.

Do they have the same volume?

Yes!!!!Since both containers are the same size, they both take up the exact same

amount of space, so they have the exact same

volume! With volume, it doesn’t matter how heavy

the matter is!

mashed potatoes rice Krispies

Look at these cups! Compare their mass and their volume.

They both have the same volume because they are both the same container. However, their masses are

different. Mashed potatoes would be heavier

than Rice Krispies!

amount of matter something contains

mass

MassMass is the amount of matter something contains. The mass of something

can be measured using a triple beam balance.

Think about the mass of these objects. Put them in order from least to most in your mind. Then click to check.

Is this what you thought?

cotton balls white sand

Look at these containers. One is filled with cotton balls and one is filled with white sand.

Do they have the same mass?

No!!!!They have the same

volume, but not the same mass. White sand has a lot

more matter than cotton balls, therefore, it is

heavier, and has more mass!

compares an amount of matter to the amount of space it takes up

density

cotton balls white sand

Density compares the volume of something to the mass of something!

Mass: 100 gramsVolume: 136 cubic centimeters

Mass: 200 gramsVolume: 136 cubic centimeters

Density= mass divided by volume!100/136= .74

Density= mass divided by volume!200/136= 1.47

WHITE SAND IS MORE DENSE!!!

mashed potatoes

216 g.

Rice Krispies104 g.

What conclusion could you draw about density from this information? Each measuring cup is filled with a certain food. It’s mass is given.

Chips83 g.

The chips are the least dense. The mashed potatoes

are the most dense, and the Rice

Krispies are in between.

If you wanted to measure the density of these items, which tools would you use?

length X width X height

If you wanted to measure the density of these items, which tools would you use?

length X width X height

If you wanted to measure the density of these items, which tools would you use?

length X width X height

ability of matter to float in a liquid of gas

buoyancy

The less dense an object is, the more buoyant it is! Which of these items do you think is buoyant?

Bobbers float on water when you’re fishing!

Wood also floats! That’s

why boats are made of wood!

forms when different particles of matter mix evenly inliquid

Solution

If I mixed these together, would it be a solution?

YES! You could NOT un-mix it!

If I mixed these together, would it be a solution?

NO! You could un-mix it using your hands or a magnet!

If I mixed these together, would it be a solution?

YES! You could NOT un-mix it!

If I mixed these together, would it be a solution?

NO! You could un-mix it using your hands or a

filter!

measures the amount of one material that will dissolve in another material

solubility

what happens when one material forms a solution with another material

dissolves

Some things dissolve easily in water!Which ones do you think?

Leaves won’t dissolve.

Sugar dissolves

VERY easily– especially in warm water!

Chocolate will dissolve,

but not as easily as sugar!

Salt will dissolve, but not as easily

as sugar!

I tricked you! Ice doesn’t dissolve, it

melts! Plus, ice is the same thing as water, so

it’s not a different material.
