CLASS X HOLIDAY HOMEWORK
Dear Children,
Vacation has just one letter difference with vocation.
Summer vacation is the time when you can be more
candid and creative. This is the time when other skills,
than intellectual skills, can be nurtured and developed in
your soft and evolving brains. Holiday assignments are
focused to let the creative and latent talents, skills and
desires of the children blooms with creativity so that they
may be identified and themselves to get self-motivated.
So Young Talented Brains, Get… Set… Go… Enjoy doing
the activities and ensure timely completion of the given assignments.
Remember a well presented Holiday Homework fetches you a

PHYSICS
Electricity is a vital part of our life. During summer, we tend to use maximum amount of electricity
by using coolers and air- conditioners even when we are aware about the shortage of electricity .
This summer, you have to calculate your own electricity bill. Points to be noted are: (1) Calculate your electricity bill for fifteen days according to the following format:S.No. Name of
the
appliance
6
Power of
appliance
Number of
appliances
Usage time
Electricity
consumed in one
day (KWh)
Electricity
consumed
in 15 days
(2) Observe the areas where you are wasting electricity. Mention any 5 of them.
(3) Mention any 5 ways to save electricity in your house.
The project should be made on A-4 size sheets. (For better presentation paste relevant pictures and
authentic proof of electricity bill)

BIOLOGY
It’s an initiative taken in the form of holiday homework for our class X scholars to make them realise the
importance of natural vegetation and animals. Natural vegetation belongs to each one of us and all of us
have the responsibility to contribute towards its conservation. Natural vegetation has undergone a
change as man's interference has increased. The children will focus on natural vegetation & endangered
animals through poster making will be included in co-scholastic Area (English-literary and creative skill
and poster-Attitude and Values), doing case study on Forests (Science) . The homework for all subjects
will be done in one scrap file on A4 Coloured Sheet.
Biology: Case study on Forest
Project 2 (for the second half of the class)
A. Make a poster on the topic „Save Animals‟.
B. Write a poem (80-100 words) on „Let the animals live‟
C. Write an article in your newspaper on the different ways to conserve forest and home of the
animals. Gather some information on the same from different sources (newspaper, internet etc.)
and with the help of pictures explain animals can be protected and their habitat can be conserved.
7
Read the newspaper and collect 10 articles dealing with Ecology/Environment. Paste them in a
scrap book.
D. Make a vocabulary corner in your newspaper. Choose 10 words (to do with endangered species of
animals, Ecology /Environment) and write them down as anagrams.

Choose any one method of communication from various means of communication like
radio/television/satellite which are used by government departments as the Indian meteorological
department to disseminate information. Find out how the information is disseminated by them at various
levels during disasters. Prepare a report.
TOPIC-POCKET GUIDE ON FIRST AID (ROLL NO 22-33)
Prepare a pocket guide on First Aid for your school. The first aid pocket guide should contain aid that
needs to be given for fractures, poisoning, cuts and burns, heat and cold wave and other threats that are
prevalent in that area.
The content shared in the guide should be supported with adequate pictures so as to give a clear and
elaborate understanding about the topic. Choose awareness campaign strategy for either senior citizens or
illiterate people and prepare a brief write-up.
