LESSON 1: 10 minutes

Can you always see the parts of materials?

If you eat a pizza, you can see the cheese, the pepperoni, and the other parts it is made from.

Can you always see the individual parts when you mix materials?

Procedure

1. Read and complete a lab safety form.

2. Observe the materials at the eight

stations your teacher has set up.

3. Record in the Data and Observations

section below the name and a short

description of each material.

LESSON 1

Substances and Mixtures

A. What is matter?

1. Anything that has mass and takes up space is considered to

be

.

2. Types of

, including heat, sound, and electricity, and

such as magnetism and gravity are not matter.

B. What is matter made of?

1. The building blocks of matter are small particles called

.

2. The different ways that atoms combine with each other help us identify different

types of

.

C. Classifying Matter

1. Scientists classify all matter into two main groups:

and

.

2. The difference between the two main kinds of matter is

their

.

1. Matter with a composition that is always the same is

a(n)

.

2. A substance made up on only one kind of atom, such as gold is

a(n)

.

a. Some elements are formed of

, which are units

formed of two or more atoms that are held together by chemical bonds.

b. There are about 115 elements, each of which has its own

chemical

.

3. A(n)

is a substance made up of two or more elements

that are chemically joined in a specific combination; most matter is formed

of

.

E. What is a mixture?

1. Matter that can vary in its composition is a(n)

2. The substances that make up

.

are not bonded together.

F. Types of Mixtures

1. Mixtures differ in how

the substances that form them

are mixed.

2. A mixture, such as trail mix, in which the substances are not evenly mixed is

a(n)

mixture.

3. A mixture in which two or more substances are evenly mixed, but not bonded

together is a(n)

mixture, also called

a(n)

.

4. All three states of matter can be a(n)

or a solvent in

a solution.

G. Compounds v. Mixtures

1. The parts of any kind of

, including trail mix, soda,

and air, keep their properties.

2. The atoms that make up a(n)

are bonded together, so

its composition is always the same.

3. The substances that make up a(n)

are not bonded

together, so adding more of one substance in a solution will not change the

composition of the solution.

4. You can separate the parts of any mixture by using

processes.

a. A(n)

, a strainer, or a ladle can be used to separate the

parts of a(n)

mixture.

b. The best methods for separating a(n)

solution¡ªis to use

mixture¡ªa

or evaporation.

H. Visualizing Classification of Matter

1. Matter can be classified as a(n)

a(n)

or

.

2. A substance can be classified as a(n)

a(n)

or

.

3. A mixture can be classified as

or

.

4. All the matter in every category is made up of

Matter and Atoms
