Do Tonight!

1.) Take Study Island Quiz: Physical and Chemical Properties

2.) Write down as many homogeneous and heterogeneous mixtures as you can find.

Properties of Matter

Notes 2-4

Things you see and do not see in this

room are made of matter

Matter: anything that has mass and takes up space

3 types of matter : elements, compounds, and mixture

Pure Substances

ElementThis simplest form

of a pure substance.

Example: Na (Sodium), Ne (Neon)

Compound• Two or more

elements that are chemically combined. Example: NaCl (Salt), H2O (Water)

Compound or Element?

Compound or Element?C12 H22 O11

Compound or Element?

NaCl – Table Salt

Compounds cannot be changed by a physical change

What is a mixture? A mixture is when 2 or more elements are joined physically

No new substance is formed in a mixture

Watch This!

Fill in the blanks on your graphic organizer.

Homework Tonight

Go home and find as many examples as possible of homogeneous mixtures and heterogeneous mixtures.

Write a list and bring to class to share tomorrow!

Ways to measure matter:

1.) Mass2.) Volume

1.) Mass is the amount of matter in an object

Mass and weight are not the same types of measurements

What do you weigh on the moon?You weigh 1/6 of what you weigh on earth. But your mass is the same. Why?

A kilogram is a unit of mass

Mass is determined by a balance

2.) Volume is the amount of space an object or substance takes up

There are 4 phases of matter: solid, liquid, gas, and plasma

Act it out!

Watch your classmates become a Solid, Liquid, or Gas.

A solid’s size and shape is always definite

A Liquid’s shape is changed by its container

Water can occur in any of the three phases (solid, liquid, and gas/steam)

The volume of a solid or a liquid isn’t necessarily determined by the shape of the container

Gas does not have a definite shape

Unlike a solid and liquid, the volume of a gas is determined by its container

Gas expands and contracts depending on the size and shape of its container

Read through the practice quiz.

We will do this quiz at the end of the video.

pH Scale

Draw this on the back of your Brain Pop:

Acids:

substance that dissociates in

water to yield a sour corrosive

solution containing

hydrogen ions, having a pH of

less than 7, and turning litmus

red.

Bases:

They are characterized by a bitter taste, a slippery feel, the ability

to turn litmus blue, and the ability to react with acids to form

salts.

Bases are alkaline: having

a pH greater than 7.
