4. A Text A Day: Forms of Matter
Everything around you is made of matter. Scientists
group matter based on its properties, or characteristics:
what it looks like and how it acts in different situations.
Matter can take three different forms. The three forms are
solid, liquid, and gas.
Solid matter has a definite shape. It also takes up a
definite amount of space. This means it has a specific
volume. If you could look at solid matter under a very
powerful microscope, you would see its tiny particles
moving back and forth. The particles are packed together,
so they vibrate in place. Their overall shape does not
change.
5. Liquid matter takes the shape of its container. When
liquid is in a cup, it is shaped like the cup. When the liquid
is in a vase, it is shaped like the vase. The volume of the
liquid stays the same. If you were to look at liquid matter
under the microscope, you would see its tiny particles
sliding past each other. Because of this unique sliding
movement, the liquid is able to change its shape so we can
pour it.
In the form of a gas, matter is usually invisible. The air
around us has several different gases, like the oxygen we
breathe in and the carbon dioxide we breathe out. If you
could look at gas matter under the microscope, you would
see its tiny particles floating around with lots of space in
between them. They spread out to fill any container the gas
is placed in.
6. Comprehension Questions:
1) What does the word properties mean in the first
paragraph?
2) What are the three forms that matter can take?
3) What does the word vibrate mean in the second
paragraph?
4) What is one difference between a solid and a
liquid?
5) Are the tiny particles closer together in a solid, a
liquid, or a gas?
7. Review
•If a word is pronounced strongly on the first
syllable, how is the word used?
•If it is pronounced strongly on the second
syllable, how it is used?
9. The card catalog is a cabinet of small
drawers or file trays containing
alphabetically-arranged cards of all the
books and other reference materials
found in the library. Each card bears the
title of the book, the classification
numbers or the call numbers and other
details about the book.
13. All these types of cards in the card
catalog (author, title and subject) give the
same information such as:
a. The call number;
b. The title, author, publisher, and date of
publication of the book.
c. The number of pages and a notation on
whether the book has illustrations,
maps, tables and other features.
