WHAT IS MATTER?
• The object that occupies space and has mass is called matter.
• Everything around us is made up of matter.
For example: chocolate cake, ice, oxygen etc.
• Even, we, the human beings are made up of matter.
• Matter makes up the walls of your house and your classroom.
• Matter is large as well as small.
• So, we can say that objects occupy space.
• But objects have mass too. (Mass is related to how much something weighs.)

• Let’s observe the smaller parts of potato.
Figure 1: Matter around us is made up of atoms
• These small parts of the potato are called atoms.
• Anything we see and can feel is made up of matter.
• All atoms are too small to be seen with an aided eye or even a microscope.
More about Matter:
• Matter is composed of different kind of atoms.
For example, silver is made of one kind of atom- silver atoms.
• Matter can change from one form to another.
• Like ice in the soda melts; glass melts; etc.
• When ice in the soda melts, where does it go? What does it become?

• When ice in the soda melts, it gets converted into liquid state.
• Thus, we can conclude that:- there are three states of matter:
