They take up space

They have mass

Mass is how much there is of an object. It is related to how much something weighs, but mass and weight are two different things.

PROPERTIES OF ALL OBJECTS:

Objects that take up space and have mass are called matter.

All matter is made up of lots of tiny particles that are too small to be seen by the eye.

SOME EXAMPLES OF MATTER?

Physical properties refer to the characteristics of an object that can

be seen without changing how that object looks.

Some examples of physical properties are:

Shape

Volume

Movement of particles

Spacing of particles

PHYSICAL PROPERTIES

When we describe matter, we use the physical properties to

talk about the states of matter.For example, if I was

describing a solid I would say that ALL solids have a definite shape and a definite volume.

Notice I didn’t say that they are hard. I didn’t say that because not ALL solids are hard. Think about your hair. Is it

hard?

PHYSICAL PROPERTIES

SolidsEx. Rocks, chairs, clothes, paper, ice, etc.

LiquidsEx. Water, soda, milk, juice, etc.

GasesEx. Oxygen, helium, carbon dioxide, etc.

THE STATES OF MATTER

Ways to describe solids:ALL solids have a definite

shapeALL solids have a definite

volumeThe particles in ALL solids are

packed closely togetherThe particles in ALL solids

vibrate in place.

SOLIDS

There are two ways to find the volume of a solid. You must determine the type of

the solid before you can find the volume.The two types of solids are rectangular

solids and irregular solids.

FINDING VOLUME OF A SOLID

An example of a rectangular solid would be a book. A book has a length, width, and volume.

To calculate the volume of a book, you would first measure the length, width, and height. Then, you multiply those

values together.

Length x Width x Height = Volume

VOLUME OF RECTANGULAR

SOLIDS

To find the volume of an irregular solid, you will need to use water displacement with a graduated cylinder.

Water displacement means that you would put water in the graduated cylinder. Then, drop the solid into the cylinder. Then however much the water rose would be the volume of

the solid.Volume of irregular solid = new water

level – original water level.

VOLUME OF AN IRREGULAR SOLID

Ways to describe liquids:

ALL liquids have a definite volume

ALL liquids take the shape of the container

they are placed in.The particles in liquids

are relatively spread out.The particles move apart from each other and flow

from place to place

LIQUIDS

To find the volume of a liquid, scientists use a tool called a graduated cylinder.

A graduated cylinder is similar to a measuring cup in that it shows measurements in increments on the outside of the

container.

FINDING VOLUME OF A LIQUID

Ways to describe gases:ALL gases have no definite

volume.

ALL gases take the shape of their container, filling all of

the available space.

The particles in a gas are spread out in the available

space.

The particles move easily through the available space.
