Do You Know?Plants are also living things. A small plant is born from a seed and grows up to become a big plant.

Plants also need food and air to grow.

Plants do not move from one place to another. But they move their parts. Like, the sunflower turns its face towards the Sun. The leaves of the touch-me-not plant close down when touched.

A car also moves on the road. But it is not a living thing. It cannot move on its own. It needs a driver to start its engine and move it. So a car is a non-living thing.

Living things feel. Living things breathe. Living things have young ones.

Non-living Things Non-living things cannot eat, breathe or feel. They cannot move or grow. They also cannot have babies.

Non-living things are divided into two groups—Natural things and Man-made things.

Teacher’s Notes:

Living and non-living is a difficult concept to understand. Take the students around the school. Point out living and non-living things.

Ask the children the differences between a doll and a child.

Make flash cards. Show each card to the students Ask them whether it is a living or a non-living thing and why? This way, with every picture, the characteristics of living and non-living will be repeated again and again.

1. Make two non-living things using some plasticine.

2. Note down some of the activities of your pet in your notebook.

Life Skills

Take a walk around the school and find two non-living things which are natural and two

non-living things which are man-made.

Field Trip

Collect pictures of living and non-living things from old newspapers and magazines. Paste

them in your scrapbook.
