## What will happen if you go to space without a spacesuit?

To understand this, we will have to first know why astronauts/cosmonauts wear space suits. It is obvious that special space suits have been created because living in space is different than living on earth, or even flying in a aeroplane.

## Gravitation

Here is a worksheet that attempts to give a human touch to the teaching and learning of the concept of "Gravitation". It will further facilitate the thinking & research skills of students while integrating the laws of gravitation and related concepts with other subjects.

## Solar System

This worksheet is designed to help students connect the concept of the Solar System with other subjects like languages and mathematics. The worksheet will also help them develop problem-solving skills.

## Forces at work

We use forces all the time to move things, lift things and travel. A force is a push or a pull that makes an object do something. For instance, when you kick a ball, it is the force that you apply while kicking that causes the ball to move. Forces can make things change directions, speed, and shape. Force is one of the most important aspects in the discipline of science and it is essential that we have at least a basic understanding of this concept.
