ACADEMIC SESSION: 2018 - 19

Class XII (CBSE)

Holiday Research Work (Integrated Assignments)

STUDENT’S NAME: -- DATE:--

Summer is the anthem of the childhood. It is when you generally throw your school bags away,

take a break from your rigorous academic work. It is a time to relax, visit your relatives and

friends, watch movies, play both indoors and outdoors, eat a lot, etc. It is a time to do something

new, something different. While doing this and more, we also want you to spend at least an

hour doing some serious academic work, honing your research skills.

Attached with these guidelines is Holiday Homework to be completed during the summer break.

Please read the task carefully and carry out the research project as best as you can. You are expected to bring this back

with you on the first day of the school after the summer break.

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. Learning doesn’t stop when school is out: Instead of spending time playing video games or on facebook or watching

TV, find other ways of entertaining yourself – 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: We are aware that it is very hot during summer break

but you still need to get out and play either early in the mornings or late in the evenings. Keep yourself fit and

healthy.

3. If you are bored, help out at home: You will get easily bored during the summer. Try helping your parents in house

chores. For example, Try cleaning your room and reordering it completely.

4. Reading is a must: Reading nurtures your soul. Keep aside at least an hour to read good novels. Your English

teachers will suggest good books to read. When you visit malls, make sure you drop in at a bookstore.

5. There is no sleeping all day and staying up all night: While it is understandable that you need unstructured time

during the summer, make sure you do not stay up all night and sleep during the day. 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.

Some doS and don’tS during Summer vacation:

Dos

Drink lots of water – at least 8-10 glasses per

day. Carry a water bottle everywhere you go.

Lime juice and fresh fruit juice act as

refreshments and quickly replenish body’s

lost fluids.

Wear light coloured fabrics and full sleeved cotton clothes. This will keep your body

cool and protect you from UV rays. Don’t forget your hat and sunglasses.

Use sunscreen (with minimum SPF-15) and apply it at least 20 minutes prior to sun

exposure.

Eat small, light and frequent meals. Eat lots of vegetables and seasonal fruits.

Stay indoors as much as you can.

Discover your creativity through Research work sheets.

Study for an hour everyday.

Explore various games.

Enjoy your holiday trips.

Don’ts:

Don’t be out in the open between 11 am and 4 pm.

Don’t have junk food and fried food items.

Don’t watch too much TV.

Don’t waste time in being lazy.

Don’t dirty your place of living.

-- Viva Voce on the Project or Market Survey Report-5 Marks

-- The questions should establish that the report is the original work of the

student and that the student has a reasonably clear understanding of the

work carried out by him/her.

-- Entrepreneurial qualities such as leadership, self-belief, creativity,

originality, initiative etc. May also be assessed by asking a variety of

questions related to the report.

-- Case Study-10 marks

-- A case study is a focused research on an organisation, enterprise,

practice, behaviour or person undertaken to highlight an aspect that the

study attempts to examine. For instance, a case study may be conducted on

the pollution control methods being employed by an industry. Or a

successful industrialist may be chosen as a subject of a case study to

analyze and understand the strategies that the industrialist adopted: To

achieve success.

-- Ideally, a case study should be conducted on subjects with the objectives

of bringing to the fore beliefs, practices, strategies, values etc. That have

made them what they are. Such studies help us to understand the way in

which great minds think and operate. We may also conduct case studies on

failures; why a company collapsed, how a service lost its market etc. From

both the types of case study, we learn lessons; how to do something or how

not to do something. They also provide valuable insight into the processes

involved in an enterprise.


1. Students will be able to understand the industry as a whole

2. A survey would help the students to establish a better cause and effect

relationship and gain an in depth understanding of the topic selected.

GRADE – X11 ENGLISH

HOLIDAY HOMEWORK - 2

Student’s Name: Date: /04/2018

Read the passage given below carefully and answer the questions that follow:

1. The youth is a dynamo, an ocean, an inexhaustible reservoir of energy. But this energy cannot be kept in

prison. Its basic nature is to flow , to express itself. The youth energy on the basis of the nature of its

expression can be divided into four categories.

2. The vast majority of the youth today are with the establishment, whose formula of life is learn, earn, burn,

and enjoy. It means learn to operate the modern devices and employ them to earn the maximum amount of

wealth to the point of burning the natural resources of the earth , as well as yourself out, and then enjoy your

own funeral. This category of youth is intelligent, skilful and hardworking but it lacks insight and foresight.

They are self-indulgent and any sense of moral code of conduct is alien to their nature. Neither are they able

to see in depth, to find out whether there is a deeper meaning and purpose to their human life, nor have they

the capacity to look beyond the tips of their nose to find out the consequences of their way and approach,

where it is leading them to. They are the ends unto themselves and enjoyment is the motto of their life.

3. The second category of youth in nature and approach is the same but as it is less privileged and less

qualified and skilled; it has lesser opportunities for earning and enjoying. Such youth may be incited to be

against the establishment. This opposition takes various forms. When it is well organised and systemic it may

take the form of political opposition and even go to the extent of expressing itself in unjust ways. When the

opposition is not so intense and organised , it remains content with giving verbal expression to its resentment

periodically. The youth of the above two categories need to be shown the correct path to positively

channelize their energy.

4. The third section of youth is a sober and thoughtful class of people, which objectively observes and studies

the phenomenon of development of the world. These youth find that man in his insatiable thirst for

consumption has become blind and lost the sense of distinction between milk and blood .Today man in his

mad rush for exploitation is sucking the blood of Mother Earth; leading to their destruction and is thereby

digging his own grave . This responsible category of young people is looking for an alternative mode of

development based on co-operation between man and man. This development based on mutual love,

friendship and harmony is not only sustainable but leading to endless prosperity mutually. To bring about his

natural revolution from death-movement to life-movement is the aim of this group.

5. The fourth and most vital group of youth which is going to usher humanity into the third millennium and

act as the pioneer for the future development of planetary life is engaged in evolving a new way of life and

releasing a new principle of global consciousness through a fundamental research in the science of life. The

science of life is a new branch of knowledge which takes the whole man into account without dividing him

into subjective and objective halves of spirituality and physicality and does not treat him either as a refined

(thinking) animal or an ethereal entity, having its base in some other non- physical world. It , rather,

recognises man as a basic unit of conscious life which has got immense, practically inexhaustible,

possibilities and potentialities for evolution, development and growth. As per the Vedic formula, man is the

micro-cosmos and his fullest flowering and enfoldment lies in his identification with the cosmos.
