42 Looking Around
Gopal was waiting for his mausi’s family to visit them. They will
be coming the next day for their holidays. He was thinking
about all the fun and nice food that he would have with his
cousins. Just then his mother called out, “Gopal, before you
sleep, remember to soak two small bowls (katoris) of chana
(gram).” She was going to his Bua’s house and would return
only in  the morning.
As he was soaking the chana, Gopal thought, “How will two
small bowls of this be enough for eight persons?” So he soaked
another two bowls of chana. When his mother returned the
next morning, she saw that the chana were overflowing
from the vessel. “How much did you soak?” asked his
mother. “How did that happen!” wondered Gopal.
“You soaked too much! Anyway it is good, now I
will cook half of them, and leave the other half to
sprout. I can send these to your aunt. The doctor
has told her to eat sprouts”, mother said. She
tied half of the soaked chana in a wet cloth,
and hung them up to sprout.

Discuss
 What things are soaked before cooking in your house? Why?
 What things do you eat after sprouting? How are they
sprouted? How much time does it take?
 Has the doctor or someone you know ever told you to eat
sprouts? Why?

Do you remember that in Class IV you did an activity

 Put a damp piece of cloth or some cotton wool in the
second bowl. Now keep the same number of chanas in
it. Make sure that the cotton wool or cloth remains wet.
 Put the same number of chanas in the third bowl.
Do not put anything else in it. Cover all the three
bowls.
Teacher’s Note : Sprouting time of seeds may vary according to the temperature

Project : Plant your seeds
Take a clay pot or a tin can with a wide mouth. Make
a small hole at the bottom of the can. Fill your can with
soil. Put four or five seeds of the same kind in the soil
and press them gently. Different group can plant
different kinds of seeds, such as mustard (sarson),
fenugreek (methi), sesame (til) or coriander (dhania).
When you split the whole
masoor, you get me – masoor
dal. But then you cannot
sprout me! Can you think why?
Draw
 Look carefully at your sprouted chana and make its drawing?
Write
Name of the seed : ____________
The date on which you planted them: ___________
The day you observe something coming out of
the soil, start filling the table:
Date Height of the Number of leaves Any other change
plant (in cm) seen
To find the
height of a plant
use thread and
then measure it

So many seeds!
How many types of seeds can you collect?
Where will you find them? Each of you
should try to collect as many different
types of seeds as you can. After that, put
all the seed collections together. Now
observe these seeds carefully – their
shapes, sizes, colours, textures (smooth
Plants which hunt!
There are some plants which trap and eat
frogs, insects and even mice. The Pitcher
plant (Nepenthese) is one such plant. It is
found in Australia, Indonesia and Meghalaya
in India. It has a pitcher-like shape and the
mouth is covered by a leaf. The plant has a
special smell that attracts insects to it. When
the insect lands on the mouth of the plant,
it gets trapped and cannot get out. What a
clever way to hunt!

 Do some plants grow without seeds?
