Information for Teachers

  • Matter is all around. Anything we can hold in our hands is made of matter. Matter is anything that has weight and takes up space. There are things which are not matter such as, heat, light, sound, electricity and time. Even the air which can`t see is matter. It has weight and takes up space.


  • Every object that we can think of, including your-self is made of matter.
  • Matter is anything that has weight and takes up space.
  • Matter exists in three forms, solids, liquids and gases. Solid has a fixed shape and volume. Gas does n`t have a fixed shape or fixed volume. It attains the shape of the container and also takes up the whole space of the container.



  • Solids keep the same shape
  • Liquids changes shape according to that of the container.
  • The gases spread out to fill the whole space of the container.

Material / Resources

Writing board, chalk / marker, duster, balloon, thread and balance, textbook,


  • Show students different objects or pictures of different objects which are solids and liquids. Ask them to put them in 2 different groups on the basis of their similarities.


  • Let them make the 2 groups as they see fit now ask them to arrange the objects in 2 groups on the basis of the following:


    1. Objects which are hard and have a definite shape
    2. Objects which can flow and have no definite shape


  • Tell them that the objects in group 1 are solids and in group 2 are called liquids.


Activity 1

  • Divide the class into suitable groups and ask each group to look for different objects around them that fall in the group of solids and liquids. Students list the objects.



  • Now ask them to write with each list the common features of the group of objects. Write the responses of all groups on the board and highlight the key points.

Activity 2

  • Write three properties of the balloon.


    1. What is the difference between the balloons in picture A and Picture B? Describe the change.
    2. What are the weights of the balloons in picture A and picture B.
    3. Why is the weight of the balloon more in picture B?
    4. What changed the weight?
    5. What does this picture show? (Air has weight)
  • Tell the children that anything that has weight and occupies space is called matter.
  • How do picture A and picture B prove that air is made up of matter?

Quick Quiz:

  • 1.      Identify three things that are made of matter.
  • 2.      Name a thing which is not made of matter.


Activity 3

  • Ask the students to observe the given or a similar picture and to identify the three states of matter.
  • Ask the students to identify solid liquids and gas by observing a hot cup of tea in winter.

Quick Quiz:

  •  Identify the three states of matter in your body.
  • Give the following worksheet to students and ask them to complete the table.

S. no.
