Statement of Aim

So, today we are going to study the topic ‘Mixture’

Presentation 

Teaching point 1: Definition of mixture

Mixtures are constituted by more than one kind of pure matter, known as substances.
In other words, Mixture contains more than one substance.

Teaching point 2: Types of mixtures

There are two types of mixtures on the basis of nature of the components that form a mixture:
1. Homogeneous mixture- Mixture which have uniform composition throughout, are called homogeneous mixtures.
They possess same properties and combination throughout their mass. E.g. Sugar in water
2. Heterogeneous mixture- Mixtures which contain physically distinct parts and have non-uniform combinations are called heterogeneous mixtures.
These mixtures possess different properties and combinations in various parts.
E.g. mixtures of salt & sulphur, oil & water etc.

Teaching point 3: Activity on types of mixtures
  • Take two beakers.
  • In first beaker, take 1 tsp of salt and add water to it. Mix it well and say this as group A.
  • Fill second beaker with water and add 1 tsp oil into it. Say this as group B.
  • You will notice that, group A mixture has obtained uniformity. Such mixtures are homogeneous mixtures.
  • Mixture of group B is still non-uniform. You can clearly see both oil and water in different layers. Such mixtures are called heterogeneous mixtures.

Blackboard Summary

  • Mixtures are made up of more than one substances.
  • Mixtures are of two types- homogeneous and heterogeneous.
  • Homogeneous mixtures have uniform composition.
  • Heterogeneous mixtures are non-uniform in composition.
  • Properties of homogeneous mixtures are same throughout their mass.
