ACADEMIC SESSION: 2019 – 20

Class XII (CBSE)

HOLIDAY INDEPENDENT PRACTICE

STUDENT’S NAME: DATE:

Dear Children,

We are sure that you will enjoy your summer vacation with members of the family and

friends. Some of you must be planning to travel or to visit your relatives and

grandparents. It will be great if you spend some time with them and gift them

something that is handmade and designed by you. This will surely make them feel

special. If possible, join some activity classes or learn something new during your

holidays. Spend some time reading storybooks, newspapers, watching interesting and

informative programmes. Help your parents by cleaning up your room, arranging

things kept in the cupboard and donating things that you do not need to a NGO.

We are attaching a few interesting activities and assignments which you are expected to do during the break.

This will also help you avoid the noon time heat. Write neatly and present your work well. Please complete

the work and bring it to school on Thursday, June 6, 2019. Have lots of fun and take good care of yourself.

Six things to remember during summer vacation:

While your parents and we want you to have fun during summer break, we also want you to be thinkers and

doers. The following guidelines will help you to be both, while enjoying your freedom at the same time.

1. Find other ways of entertaining yourself than phones and TV, learn a musical instrument like guitar or

keyboard, learn a hobby like origami or magic tricks, read novels, learn cooking, etc.

2. For every hour of electronics, you give one hour of play time

3. If you are bored, help out at home. This will also earn brownie points with your parents and help

you realize the importance of organization and cleanliness.

4. Reading is a must. Reading nurtures your soul. When you visit malls, make sure you drop in at a

bookstore and pick books that interest you. Otherwise, read on Kindle.

5. There is no sleeping all day and staying up all night: It is unhealthy and it will be hard for you to

readjust to regular school schedule at the end of the vacations.

6. Make sure you make time for your parents: Watch a movie, go out on dinners with your family and

spend more time with your family than with your friends.

NOTE MAKING

Student’s Name: Date: /05/2019

Information is power. It is predictable, therefore, that those in authority will seek to manipulate others

through the control of data. However, all information in a democratic society should be freely available

unless there are specific, well-formulated reasons for withholding it in the interest of security.

The Freedom of Information (FOI) functions at a number of different levels: in itself, for the fulfilment of all

other rights and as an underpinning of democracy.

Information held by public bodies is not only for the benefit of officials, politicians or other designated

people associated by the organisation, but also for the public as a whole. Unless there are good reasons for

withholding such information, all interested parties should be able to access it. More importantly, freedom of

information is a key component of transparent and accountable government. It plays a key role in enabling

citizens to see what is going on within the government, and in exposing corruption and mismanagement.

Transparent and open government is also essential if voters are to be able to assess the performance of

elected officials and if individuals are to exercise their democratic rights effectively, for example, through

timely protests against new policies, or by using their vote against candidates who have indulged in

undemocratic activity.

Freedom of expression and access to information is a fundamental right and must be held as a cornerstone of

democracy. In its absence, government can, and often does, behave with impunity. It is argued, however, that

it is not an absolute right – the International Covenant on Civil and Political Rights (ICCPR) for instance,

specifies certain permissible constraints. One of these is the right of the state to withhold information ‘for the

protection of national security or of public order, or of public health and morals’. This is irascibly vague and

provides many loopholes for governments to use this wording as a basis for restricting information that is

inconsistent with their ambitions.

The public right to know is an intrinsic part of informed public debate, which has traditionally been

dependent on the freedom to receive and impart information without government interference. However it

may also be argued that this does not mean a right to receive any type of information from the government. It

is of paramount importance that any restrictions on information or expression regarding security matters must

designate in law only the specific and narrow categories of information absolutely necessary to protect a

legitimate national security concern. A threat to national security can be defined as ‘any expression or

information that is intended to incite imminent violence, or is likely to incite violence’. In addition, there

must be a direct and immediate connection between the expression and the likelihood or occurrence of such

occurrence of such violence. The public interest in having information at all times must remain a priority

consideration in any FOI Bill, and that any denial of this right should be subject to independent review.

Along these lines, in a seminal judgement in 1982, the Supreme Court held that, “The concept of an open

Government is the direct emanation from the right to know, which seems to be implicit in the right of free

speech and expression. ….. disclosure of information in regard to the functioning of government must be the

rule, and secrecy an exception, justified only where the strictest requirement of public interest so demands’.

On the basis of the above passage, make notes on it using headings and sub-headings. Use recognisable

abbreviations wherever necessary.
