How to Explain the Big Bang Theory to Children

One of the most important parts in a child's general education is to explain how the world was created, the place where we live and its origin. Children may want to know about the Big Bang Theory, the scientific theory which explains how life on Earth came into being. It may be a shocking fact for children because of the novelty and the number of new concepts that they must understand and internalize. Therefore, a maximum delivery from the teacher or parent is required, since it is a new and fascinating topic: a child's first approach to the Physical World. OneHowTo.com will easily show you how to explain the the Big Bang theory to children.

You'll need:

  • Photos.
  • Videos.
  • Books.

Steps to follow:


First, children should internalize the concepts of infinite, nothingness and of energy. Children should be aware that everything comes from an infinite space in which there are only particles of energy, the rest is simply nothing or empty.

The universal explosion must be explained in detail. Children should understand that particles of matter and energy collide, which led to the explosion and the birth of the Universe.


The concept of origin is very important so that children are aware that the Universe had a beginning and that has nothing to do with what we know now, and it all happened after the explosion.


Also, children must internalize the concepts of matter and evolution: how after the Big Bang matter arose to form the planets and our Milky Way, and therefore all life in general.
