CLASS IX HOLIDAY HOMEWORK
Dear Children,
Vacation has just one letter difference with vocation.
Summer vacation is the time when youcan 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.

MATHEMATICS HOLIDAY HOMEWORK
CLASS 9
 Nature and its surroundings
Project:Exploring Mathematics around us.
Description: 1. Look around yourself.




In the nature …
In the house …
In the market…
In thegarden … so on
2. Click photographs using a digital camera/mobile andexplore the hidden mathematics.
For Example; In the nature (When counting the number of petals of a flower, it is most probable that
they will correspond to one of the Fibonacci Numbers.For example; White calla lily has one petal,
Euphorbia have two petals, Trillium have three petals and Columbine have five petals. Explore more such
examples from internet)
In the house (Identify the shape of the rooms, find out its area, perimeter and volume)
In the market or in a cricket field (Identify the different 3D shapes such asspheres, cubes, prisms,
cones, and pyramids in the objects around) Etc.
3. Click minimum 20 photographs. Along with each picture, write 4-5 lines explaining how you have
related mathematics to it.
4. Your innovative ideas to find out mathematics in photographs will be judged.
Each student is required to make a hand written project report.
Lay out of the report will be as follows:

ACTIVITY

The Wheel of Thedorus is named after the Greek philosopher Thedorus of Cyrene who is known for his
contribution in understanding of irrational numbers.

To construct the wheel of Thedorus, start by locating the centre of an A-4 size sheet or an ivory sheet.
This will be the starting point for the construction of your wheel. Take a line segment of length 1 inch
from the starting point parallel to the bottom of the sheet. Construct a square root spiral starting from
this line.(Refer to NCERT , Exercise 1.2, Activity given in question 4)

Decorate it in the way you want.

Your work will be assessed on the basis of accuracy and creativity.

HOLIDAY HOME WORK OF CLASS 9
PHYSICSIS THE NATURAL SCIENCE THATDEALS WITH THE STUDY OF MATTER,
1.
ENERGY AND INTERACTION BETWEEN THEM
To acquire the “KNOWLEDGE OF NATURE” let us explore the following project:
We all know that every object in the universe attracts every other body with a force by virtue of
masses. This force was supposed to be thought upon by Newton while contemplating on the free
fall of the apple towards the ground. Identify the force and collect information on the topics listed
below:
1.Universal law and factors that affect it
2.Mass and weight
3.Acceleration due to gravity and its variation
4.How it is responsible for planetary motion and revolution of a
satellites in orbits around the earth.(principle of launching satellite,
orbital velocity, time period)
5.Kepler laws of planetary motion.
Each student is required to make a hand written project report. Lay out of the report will be as follows:

Biology
Nature is the beautiful manifestation of cell in different life forms. Let’s explore and investigate the
cell by doing this activity
Objective: To reinforce understanding of cell structure and its functions.
INSTRUCTIONS
The holiday home-work consists of a project and an assignment. This is a part of your FA2 activity and
has a weightage of 15 marks i.e. project (10marks) and assignment (5 marks).
You will duly submit all of this on 4 th of July 2016. Marks will be deducted for any delay in the
submission of the home work.
Project and Task
Each student will make a project on the topic assigned below.



PLANT CELL
ANIMAL CELL
PROKARYOTIC CELL (model)
(ROLL NO: 1-12)
(ROLL NO: 13 -24)
(ROLL NO: 25 onwards)
Things required: A-4 sheet or ¼ of chart paper, scissors glue drawing pencil, colour .
PROCEDURE: (ROLL NO: 1-24)
PART ONE: Find out meaning of analogy and write it on an A4 sheet. Also write some examples to
illustrate meaning of analogy.
PART TWO:
1. You will work individually to create a poster simile of a cell.
2. Choose a human built structure to serve as the basis for your cell similes.. The title of yourposter will
be “ACell is like a…………..”. In the blank space you will put the name of your human built
structure such as “anairport,” “a football game,” “a circus,” “a shopping mall,” etc. The poster will
actually show your human built structure – NOT the cell.
3. Choose details from your human built structure to compare to the structures and functions ofthe
Organelles of a cell. Often a cell is compared to a factory. A sample is attached – you willNOT use a
factory for your simile.. The logic and richness of your similes will help you to learnbetter how a cell
and its structures function together to enable the cell to grow, acquire and use energy, produce wastes,
divide, communicate, etc..
4. Next to each part of your human built structure, you will put a sentence that compares thatpart to a
part of the cell. EXAMPLE: “Just as a shipping/receiving department determines whatenters or
leaves a factory, so the cell membrane selectively determines what can enter or leavea cell.”
5. Use the following organelles/structures:
Plasma membrane, Mitochondria, Lysosomes, Cytoplasm, Nucleus, Rough endoplasmic reticulum,
Golgi Apparatus
BONUS: Centriole, Nucleolus, smooth ER
PROKARYOTIC CELL (model/chart)
- (ROLL NO: 25 onwards)
PROCEDURE:
 Make a three D model of prokaryotic cell (bacterial cell) Include all the parts of it.
 You can use material like Styrofoam, wood,clay etc.
 Model size must be at least 20x20 cm.
Choose details from your human built structure to compare to the structures and functions ofthe different
parts of the cell. For exampleProkaryotic Cell is like a Fort.”.
Note: For chart follow instruction given for(ROLL NO: 1-24)
Strive for EXCELLENCE
• Plan graphics that illustrate the simile
• Excellence. Is your poster creative, original, and interesting?
Assessment: Your posters will be evaluated on the following criteria:





Followed instructions-01
The. logic and richness of your similes-03
Correctly described the function of each structure-03
Organization and neatness-1.5
