The term Science comes from the Latin word, ‘scientia’, which means ‘knowledge’. It is not just about laboratories, microscopes, space shuttles etc. Explained in a simple way, Science is everything that you see around you, both living and nonliving. It tells us how things in the universe work.

Have you ever wondered what we are made of? When you build a house, you use bricks of different shapes and sizes for each area of the house. Living things too are made up of bricks called Cells, which are unique to that particular type of organism. For example, a plant body will have only plant cells and an animal body, only animal cells.

Each living being follows a particular growth pattern. Some stages are similar whereas others may be unique to each group of organisms. Even producing young ones is different in each organism. Let’s look at the details.

What is Matter? Is it anything that matters? Actually it is. When we say that everything around us is Science, each object or component of Science is called Matter. All things whether living or nonliving are made up of Matter. Let’s find out what Matter is composed of.
|1. Atoms, Molecules and Compounds|
|2. Elements and their Properties|
|3. Changes in Matter|
Are Energy and Matter connected? Scientists say that Matter can neither be created nor destroyed. It can only change to another form. Energy too has the same characteristic feature. So what are the different forms of Energy that we see in everyday life? Come, let’s learn.
