1.Define the following:
Matter
Atom
Molecule
Ions
2.Mention ten example of matter
3.Name the three states of matter and Classify the following substances into the three
states of matter.
Petrol,carbon dioxide,smoke,soap,corn flour,air,cough syrup,sand and candle in molten
form.
4.Complete each sentence with the word solid, liquid, or gas.
A ____________________________ has a definite shape. It does not take the shape
of its container. It
also has a definite volume because it can be measured.
A ____________________________ does not have a definite shape. It takes the
shape of its container. It
does have a definite volume because it can be measured.
A ____________________________ does not have a definite shape. It sometimes
takes the shape of its
container and sometimes flies freely around you. These particles are not connected to
each other and takes up whatever space is available.

6.Forms of Matter
Everything around you is made of matter. Scientistsgroup 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 formsare 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 wouldsee its tiny particles moving back and forth. The particles are
packed together,so they vibrate in place. Their overall shape does notchange.Liquid
matter takes the shape of its container. When liquid is in a cup, it isshaped 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.
Answer the following questions based on the reading passage. Don’t forget to go back to
the passage whenever necessary to find or confirm your answers.
1) What does the word properties mean in the first paragraph?
2) What are the three forms that matter can take?

3. 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.MATCH THE WORD FROM BELOW TO ITS MEANING. YOU

4. c. volume of matter
d. mass of matter
4. Mass is __________.
a. the measure of how much
material an object is made of
b. anything that takes up space and has mass
c. the color or shape of an object
d. both b and c
9.WHAT MAKES UP MATTER?
Matter is made up of tiny particles. These particles are called
atoms. Atoms are the smallest unit of matter. You can’t see atoms
because they are so tiny. Two or moreatoms can join together to make
larger particles of matter. These larger particles can join other
particles to make up the matter you can see. Atoms join together to
make up different kinds of matter. Oxygen is made up of just one kind
of atom. Water has two
atoms that join together to make water.
ANSWER THE QUESTIONS:
1.What is an atom?
2.Why can’t you see an atom?
3.How many kinds of atoms does water have?
4.How many kinds of atoms does oxygen have?
