Lesson 1

Let’s Begin

In this topic, you will learn the following What is matter?
lessons:

Mo.5 - L1a: What are the States of Matter? and takes up space.
Mo.5 - L1b: What are the Properties of Matter?
Mo.5 - L1c: Matter: How to Identify a Substance? Matter can have both physical and
chemical properties.

Mass
Mo5-L1a What are the States of Matter? The amount of matter in an object, measured in
grams (g). A bowling ball compared to a beach ball is
much heavier, therefore has more mass.
KEY CONCEPTS:
1. How do particles move in solids, liquids, and gases?

Vocabulary A-Z

Let us learn some vocabulary

The Earth has 9.3 time more mass than Mars
Volume

the amount of space a sample of matter occupies.
States of Matter

Volume is the amount of space a sample of matter
1000 occupies.

100 • A solid is a state of matter with a definite shape
and volume.
10
• A liquid is a state of matter with a definite volume
1 but not a definite shape.

• A gas is a state of matter without a definite shape
or a definite volume.
