The Hummingbird series of Primary Books from I to V are based on National Curriculum Framework (NCF) 2005 and the new Syllabi for classes at the Elementary Level.

In the guidelines some of the objectives of teaching the different subjects at primary stage are:

• to train children to locate and comprehend relationships between the natural, social and cultural environment;

• to nurture the curiosity and creativity of the child particularly in relation to the natural environment;

• to develop an awareness about environmental issues;

• to engage the child in exploratory and hands-on activities.

The Hummingbird series focuses on themes that allow for a connected and interrelated understanding to develop and trigger the child’s thinking in new directions. They connect knowledge to the child’s life outside the classroom and also provide an overall development of children.

The series comprises of textbooks on:

MATHEMATICS Children need to develop a positive attitude towards and a liking for Mathematics at the primary stage, along with the cognitive skills and concepts that they acquire. The content includes Mathematical games, puzzles and stories that help in making connections between Mathematics and everyday thinking.

ENGLISH An integrated approach to the teaching of language is of particular relevance at the primary level. The books address different skills of language, namely listening, speaking, reading and writing, which focus on across the curriculum approach through a variety of genres – poems, stories, role-plays and drama to develop the language skills creatively.

SCIENCE Science education should develop competence and encourage inventiveness and creativity. The textbooks incorporate activities, observation, experimentation and encourage an active approach to science, connecting it to the world around the child, rather than information based learning.

SOCIAL SCIENCE The textbooks provide the social, cultural and analytical skills required to adjust to an increasingly interdependent world. The focus of the books is on a conceptual understanding rather than lining up facts to be memorized.

ENVIRONMENTAL STUDIES Environmental Studies is a subject dealing with Man’s relation to his whole environment, viz. his surroundings, his home, his neighbourhood, his city or town, extending ever outward. The books contextualize the relevance of the subject and bring it to life.

The textbooks present the subjects in a clear, concise, logical and chronological manner. It is expected that this new series will inspire the children to analyse, demonstrate and transform their world view.

Air is present everywhere around us. We cannot live without it. It has no colour, smell or taste. We cannot see air but we can feel it when it moves. We can feel air when we travel in a train with an open window.

Look at the following pictures. Tick (�) the activities which you think are performed with the help of air.

ALL LIVING THINGS NEED AIR TO SURVIVEAll living things need air. Human beings, animals and plants need air to breathe and to live. Let us learn about this with the help of the following activities.

We cannot live without air. Let us verify it. Pinch your nostrils for a while.

What do you feel?

ACTIVITY To establish that we cannot live without air

Take two potted plants. Mark them A and B. Put Plant A in an open and airy place. Cover the Plant B with a polythene bag. After two days, you will observe that Plant A remains green and

healthy whereas Plant B has dried up. This is because Plant B did not get enough fresh air to breathe.

AIR OCCUPIES SPACETake a balloon and blow air into it. It will become bigger and bigger. So, we can say that air occupies space.

Fill air into an empty plastic bag with your mouth.

After filing air, close the mouth of the bag tightly with a rubber band.

The bag will swell up. Why has the bag increased in size?

It is because air occupies space in the bag.

ACTIVITY To establish that air has space

AIR HAS WEIGHTLike all other objects, air too has weight. Let us learn about this with the help of an activity.

Take two footballs in both hands, one without air and one filled with air.

Which one is heavier?

You will find that the football filled with air is heavier. So, air has weight.

ACTIVITY To establish that air has weight

AIR HELPS IN BURNINGAir is necessary for burning.

Light two candles. Cover one candle with a large glass jar. Leave the other candle uncovered. You will see that the uncovered candle

keeps burning. The covered candle stops burning after

sometime as it does not get enough air to burn.
