Gymnastic is a popular and artful physical activity which helps
in muscular development. It promotes co-ordination balanced
action by making our body flexible and active. The person who
performs the action of gymnastic is known as gymnast. You have
already learnt some basic activities in class 3 and 4. Here you
will learn front flip, back flip and side flip.
Did YOU know ?

Front flip Basket Ball game was
invented in 1891 in USA.

You have to perform
this activity on foam or
rubber mat. First of all,
stand in the attention
position at one end of
the mat. Bend your body forward and touch the ground using
your hand. Lower your head slowly and push your body forward
with the leg up and rotating down to the mat. Touch the mat with
leg and come to attention position.

Quick Test 1: Doing practice

Go to your school ground, place matress if necessary, and
perform the following.
1. Front flip with help of your friend and teacher
2. Front flip without help

Back flip
Now you can flip back. Study
the following figures and try
to flip back on the mat.

Side flip
Stand at ease with your hand
above your head. Bend your
body to the left and touch the
mat with your hand. Press the mat by your paw and rotate your
body to the other side. Flow the figures given. You can also flip
to the left side with the same process.

Quick Test 2: Doing practice

Go to your school ground, place matress if necessary and
perform the following:
1. Side flip with the help of your friend and teacher
2. Side flip without help

Balancing the body
Arrange players on line. Do some
warm up exercise. Run faster on
the ground. Mark curve line on the
ground with the help of powder or
ribbon. Now run faster along the curve. You can run back side to
get back to the same position.After this exercise, you can try the
following to balance your body:

Head stand
You can stand on your head. First, you should get
help from your friend to straight your body up to
stand on head. Later you can try to do it alone
without the help of your friend.Try to balance as
longer as you can.

Stand on a leg
Can you balance your body with a
leg ? See the following figure. You
can do it with the help of your friend.
Later you can try doing it closing
your eye.

Quick Test 3: Doing practice

Go to your school ground and perform the following:
1. Head stand with the help of your friend
2. Head stand without help
3. Stand on a leg

PRESENTING
LABORATORY REPORT IN SCIENCE

Do the following lab work in presence of your science
teacher and present your working in the following format.

Date of lab work ............................

Experiment 1 : To demonstrate that air has weight.

a. Apparatus Required: Football without air filled
Air pump
Wt. Balance

b. Theory
Every matter has weight. They occupy space as well. The

weight and volume of the matter can be calculated directly
and indirectly. The weight of a solid object can directly be
measured using balance. But the weight of air cannot be
measured directly. The difference between the weight of an
air filled object and that of empty object gives the weight of
the air inside it.

c. Procedures
i. Measure the weight of the empty ball using balance. Say, it

is” X”.
ii. Pump the air into the ball. Fill the air in the ball tightly.
iii. Measure the weight of the air filled ball. Say it is “Y”.

d. Observations
X = 200 g

MY WAY Science, Health and Physical Education - 5 253

Y = 210 g
Weight of the air inside the ball = Y – X = (210 - 200)g = 10 g
e. Conclusions:
From the above experiment, it is concluded that air has weight.

PRESENTING FIELD REPORT

Case study 1 : Visit the zoo nearby your locality and prepare
a report on the basis of your observation.
a. General Informations
i. Name of place : Central Zoo, Jawalakhel
ii. District : Lalitpur
iii. Date of visit : 2074/01/01
iv. Duration : 3 Hours
v. Number of participants in your group : 50

b. Objectives
i. To observe various groups of vertebrates.
ii. To observe food pattern of various animals
iii. To determine the interrelationship between living things

and non living things
c. Specific informations
i. Types of terrestrial vertebrates : Elephants, Tigers. Deers,

254 MY WAY Science, Health and Physical Education - 5

Fox, Monkeys, Peacock, Owl, Parrots, Rhinos, snakes,
ii. Types of vertebrates in water : Crocodile,Fish, Hippopotamus,

d. Observations

Fish Amphibian Reptiles Bird Mammal

Trout, Frog, toad Crocodile, Duck, Elephant.
gold lizard, parrot, Rhinos, Deer,
fish snake peacock tiger, Monkeys

Herbivores Carnivores Omnivores

Deer, elephant, Tigers, bear, Crocodile, monkeys, fish,
Rhinos snake frog Duck.

e. Conclusions
From this field visit, we came to know about the food habits

of various types of vertebrates. One type of animal depends
on other animals and plants. They also depend on non living
things like water, air, soil etc. In this way, there exists close
relationship between living things and non living things.

SAFETY RULES IN LABORATORY

1. Know the location of safety features of the laboratory
including the safety shower, eye wash, fire extinguisher and
chemical spill clean up kit.

MY WAY Science, Health and Physical Education - 5 255

2. Report any injuries to the supervisor. Do not work with open
cuts. Cover them with a bandage.

3. Do not drink or eat at any laboratory bench.
4. Wash your hands after each laboratory.
5. If a culture or chemical is spilled, notify the supervisor.
6. Microscopes are expensive instruments. So, handle it carefully.
7. Turn Bunsen burners off when not in use. Tie long hair back

and be sure to keep clothing and jewelry out of the flame.
Keep all volatile and flammable liquids away from the flame.
8. Dispose of these chemicals in the labeled waste containers,
not down the sink! Wear protective gloves if needed.
9. Biohazards: anything that touches a solution of bacteria or
DNA is considered contaminated. Put pipette tips, plastic
tubes, agar plates and anything else that has contacted
these things into an orange biohazards bag, not the regular
trash.
10. If you break any glassware, notify the supervisor. If the
glassware has not been contaminated, dispose of it in the
broken glass container. Do not throw it in the garbage can.
11. Any dirty glassware or equipment must be placed in
