Plant Life !
Rahul just came back from school, had his snacks, the phone rang. Rahul answered the phone,"Hello.." On the other end,"Hello Rahul, I am Ganesh uncle. how are you?" Rahul said, "It is long time since I saw, how are you ?" Ganesh uncle: "I am coming home evening at 6.30pm, can you let your parents know?." Rahul was very excited and happy, He informed his parents,cooked some french fries, was eagerly waiting. When Ganesh Uncle came, he greeted him, gave him water, french fries, shared with him all the good things. Rahul took Ganesh uncle to the garden to show his plants.
Ganesh uncle asked "Rahul, Is plants are living things or non living things?" Rahul said "living things.." Ganesh uncle said " Plants too have feelings like us - A Scientist named, Jagdish Chandra Bose proved that plants/trees are sesitive have feelings by using resonate recorder."

Rahul sows a seed...
Rahul was very excited today - he saw a small green stem out of the pot peep out. Few weeks ago, when he heard about his biology teacher talked about plants he was very interested. Even when he was at picnic (at mysore), he had sat near a brook and wondered how the plants got there.
A week ago, Rahul with his parents went to nursery, bought 16 pots, mud, manure and brought it home. They were are excited about buying pots and growing plants, Rahul had have seen lots of plants in his dads friend Ganesh-uncle's house. After hearing his teacher and seeing Ganesh uncle's care for the plants, Rahul too wanted to grow a small nursery of plants, take care of them like how Ganesh uncle does. He was excited to learn about those and he was very eager to seem them grow. Rahul and his parents picked a nice spot in their balcony where sunlight fell (he knew sunlight is essential for plants to grow), they mixed the mud and manure; then they filled the pots with 10 cups of this mixture. Rahul planted the cosmos seed - he loved the this plant a lot, since the plant had very bright and beatuiful yellow and orange colour flowers which were his favorite. He then dispersed the seed on the top of the mixture and covered them with one cup of mud-manure mixture. He watered the pots carefully...and cleaned up the place behind them.
Since then, he has been watering the plants. For the past few days, Rahul checked on the pots regularly and watering them regularly. Today he saw a tiny plant peeping out... Rahul was very excited, he called Ganesh uncle, and shared his news and told him that in 2-3 months, he will be able to see the bright yellow and orange flowers right on his balcony...

Rahul thinks about Seeds Dispersal
Rahul was sitting near the brook by his house - he was feeling nice and peaceful; He had brought a book to read with him. He could hear the water flow by the brook and a birds chirping. He was letting his mind wander about what he learned at class a couple of days ago.
He liked what the teacher taught about the plant life - the various aspects of it - and specifically was interested about the seed dispersal.
He looked at a plant by the brook and posed a question to it, "How did you get here ?"
----------------- stop here
He smiled to himself; he recalled what his teacher taught in the school - the seed could have gotten here by wind, or carried by a bird, or stuck to a person shirt and carried over to this place. There were many possibilities.
He then looked around decided it didn't matter how the seed got there; the plant was green and its flowers colorful.
The seed had gone through a germination process and had transformed itself into a plant. Now it has flowered and looking at on the side of the brook, moulding itself calmed him.

Interesting Life Sciences class (Seeds dispersal)
Rahul was in the class waiting for the teacher to come in; The teacher came in a bit late and announced that the class would be different; She would show a video of on plants. Specifically on pollination and how seeds travel. Rahul liked and enjoyed travel - he was already making guesses within his head on how seeds will go from on place to another - will someone pack in a box transport those boxes by trucks/ships/aeroplane. He was excited and curious to know how the seeds will travel.
His teacher switched on the video, projected on the wall.
There were several beautiful yellow and orange coloured cosmos plants in a garden inside thick woods, the flowers on the stem were in different stages - one as a bud, other blooming, the third on was wilted and dry; and the fourth one was dry long thin black seeds. In the picture, suddenly the wind speed picked up and it was blowing hard, the seeds were carried by the wind, some seeds fell on the ground a bit away from the plant, some seeds fell on the brook which was near by; the seeds were carried by the water. After some distance some seeds slowly settled on the sides of the brook. Rahul saw few monkeys came to the brook, drank water in the brook, played in the water by splashing and diving. Rahul notices that one seed getting stuck on monkeys hairy skin. Monekys walked away from the brook, there were looking for some food, they shook their body as they were walking, the seeds stuck on their skin fell down to the ground. He also saw the monkey jump up the tree, plucked mangoes ate the mangoes threw the seeds down, some of the monkey threw the mango seeds far away.
Rahul slearnt the seeds go from one place to another by other ways, not by vehicles, as he does.

Karate, Life Sciences and Hydration
At Karate, Rahul had a very good work-out; he had started on the new Kata - it was quite tough - it was called Bassai Dai - but he did practice hard. He still need to get some of the forms correct and with "ki". Rahul always feels better after a very good workout at the Karate dojo. Also, he has learned that for body to remain healthy, he has to drink a lot of water - water is like a lubricant that reduces the friction (he learned that in the Science class). Particularly, after a godo workout, he had studied that the body loses water and salt from the body and it is required to drink a lot of water and keep the body hydrated. He has understood that water along with nutritious food is very important to keep healthy.
