Identify all the different shapes from this picture and understand how did they get their shape. 

The wall clock is circular. 

A blackboard is rectangular. 

Each object has different shapes, called solids.

  • Solid is a substance that has its own shape and size.     
different shapes
  • The particle in it cannot move freely as it is closely packed.

  • Solids have tiny particles.

Activity: 

Take an apple and a knife.

Summary:

  • Solids have definite shapes and sizes.
  • In solids, particles are tightly packed.
  •  Particles in the objects are very free.
  • Few examples of solids: Bag, Chair etc.
