In the later session, we discovered about nematodes.
We started with organism classification,moved on to the nutrients required by plants. Classification into macro and micronutrients.Nitrogen being a macronutrient cannot be taken directly so we studied the nitrogen cycle . Then the difference between cellulose and glycogen and absence of a enzyme in our body required for cellulose digestion.Presence of a different type of bonding in cellulose particles or glucose.We learnt about the cyclic structure of benzene.
Then we learnt about agar-agar which is extracted from algae and solidifies nutrients so that bacteria can eat the nutrients and grow.A culture was used where sand was placed like a circle surrounding the agar agar with bacteria.
Bacteria attracted nematode or roundworms.
For the discovery of nematodes, Sydney Brenner, H. Robert Horvitz and John E. Sulston earned the Nobel Prize in medicine in 2002.Their discoveries are important for medical research and have shed new light on other organisms

How does oxygen enters the blood??
We went to collect earthworms to observe their behaviour.Poured water in the soil and earthworms appeared.
Placed them into test tubes with different solutions .They flourished in pure water and stay put in soapy water. Died in salt water and were struggling to come out.

culture activity of earthworm in which we’ll try to provide a moist environment to earthworm.
We’ll provide a food for earthworm by tearing tissues of it .after it we would put earthwormin medium that was prepared .
It was fun learning
experience to do so in Nms ,Jaipur

We performed an activity…
We took 3 types of water which were
- Salt Water
- Plain Water
- Soapy Water
We went outside and on a clear ground we made 3 circles using a stick
In one of the circle we poured soap water
The other was filled with normal water and the last one with salt water
We could observe many earthworms coming out of their holes. According to our observation we concluded that the earthworms appears
faster in the salt and soapy water compared to that of the normal water

Later we performed earthworm culture
We tore some tissue papers and filled them in a plastic cup. And transferred the worms into it and added water. Lastly, we covered the mouth of the cup with a muslin cloth. We named the earthworms Fred and George.
