I Love My India

Introduction: We need government to run our country. Government looks after the needs,

welfare and safety of the people of our country. In India we have two types of

government.

Central Government:

India became independent on 15th August, 1947. Independence gave us the

right to choose the people who would govern us. This is done by having an

election. During an election, people cast their vote and choose some people.

These people then form the government. Only those whose age is 18 years and

above can vote.

The Central government makes laws for the entire country. It has its offices in

New Delhi, the capital of India. The President, the Vice President, the Prime

Minister, other ministers and the officers of the central government live and

work in the capital.

Types of Government

The Central

Government The State

Government

The President of India is Shri Ram Nath Kovind.

The President of India lives in the Rashtrapati Bhavan.

State Government It is difficult for the Central Government to solve the problems of all the people.

Therefore, each state elects its own government. It is called the state government. The

state government looks after the welfare of the people living in that state. The Governor,

the Chief Minister, other ministers and the senior officers of the state government live

and work in the state capital.

Raj Bhavan (Punjab)

Class - 3 Science Worksheet - 6

PARTS OF A PLANT

Children, in the previous worksheet we studied about the parts of a plant- roots,

stem and their functions. We shall further study about the leaf, flowers and

fruits.

THE LEAF

Leaf is the most important part of the plant. They come in different shapes and

sizes. The flat and broad part of the leaf is called the leaf blade or lamina. In

the middle of the leaf is the main vein. A number of side veins branch out from

the main vein. The veins carry water to the leaf. The leaf is attached to the

branch by a stalk. The leaf has many tiny pores called stomata through which

plants breathe.

FUNCTIONS OF THE LEAF

A green leaf makes food for the plants with the help of sunlight, water and

air. This process is called photosynthesis. That is why a leaf is called the

kitchen of a plant.

The food made by the leaves is sent to all parts of the plant through the

stem.

Leaves of some plants such as cabbage, spinach and lettuce store food and

we eat the leaves of such plants.

THE FLOWER

The most beautiful part of the plant is the flower. Flowers are of many colours,

shapes and sizes. Flowers of different plants grow into fruits. They have

pleasant fragrance that is used to make perfumes.

PLANTS GROW FROM SEEDS

Fruits have seeds inside them. Some fruits have one seed inside them like

mango, some fruits have few seeds like orange whereas some fruits have many

seeds like papaya. Most new plants grow from seeds. When the seed gets

enough air, water and warmth, the baby plant starts growing till it grows into an

adult plant. This is how the life cycle of a plant goes on.

Children, all of you must have seen and used a music

system. The parts like CD, DVD etc which you can

touch are hardware whereas the songs or music

recorded on CD cannot be touched because they are

software installed on CD/ DVD.

INTRODUCTION TO SOFTWARE

Unlike hardware, software is that part of a computer which cannot be touched. To

make the hardware work, we need to have software installed in it.

Thus, we can define Software as a set of instructions given to the computer to do a

particular work.

Types of software:

1. System software

2. Application software

System software:

It is a set of program that controls the overall working of a computer. For example,

Operating system is a part of System Software that makes a computer run. It manages

all the input and output operations.

application software:

The software that helps us to do a specific type of work is called Application Software.

Microsoft Word, MS PowerPoint, MS Excel and MS Paint are few examples of

Application Software.

WORKING OF A COMPUTER:

There are three stages in the working of a computer:

This Input- Process- Output Cycle is also called IPO Cycle.

Example: Let us see how we can make tea using IPO Cycle:

INPUT: The data and the instructions, which we

enter using a keyboard or a mouse into a computer,

are called Input.

PROCESSING: After entering data and

instructions in a computer, the CPU works on the

input to give us meaningful information. This is

called Processing.

OUTPUT: The meaningful information that we get

after processing is called Output.

Children, let us recapitulate what we have studied earlier and do some basic

exercises:

A. Mark these devices as Input or Output Devices:

B. Multiple Choice Questions:

1. A computer displays _______ after processing the data.

a. Input b. Process c. Output

2. The _______ monitor consumes least power.

a. LCD b. CRT c. LED

3. ________ keys are either used alone or in combination with other keys to

perform certain actions.

a. Control b. Typing c. Navigation

C. Complete the IPO Cycle:
