P15 - Water Cycle

The activity, I am sharing today actually started two years back in her nursery school. Her class teacher taught her about water cycle. I am not sure when it was introduced to us when we were kids, but surely not in primary school 😂😂. 

It was not just learning the water cycle, she was supposed to talk about it. It was very difficult for me to make her remember few lines which can explain the water cycle. So, I wrote a poem which she can remember easily. 

When Sun shine heats the water,

Water becomes vapor and goes up in the sky.

Vapor cools down and becomes the cloud,

Clouds gets heavy and fall back as rain.

This is called water cycle.

First time I wrote an english poem. I was very excited and she was very happy to present it in her class.

Now, when she is in Senior KG, again her teacher explained the water cycle. As she is big now, she understood little and asked few questions to me. So, I decided to do the water cycle experiment.

What you Need:
        - One container to make sea
        - Another small container which works as rain water collector 
        - Hot Water
        - Ice
        - Fruit wrap
        - Some stones and plant cuttings (optional) to give a feeling of earth

We added hot water to the big container and placed a small container in it. We decorated the small container with few plant cuttings and stones. Then we quickly wrapped the big container with fruit wrap. This fruit wrap will not allow the vapour to go out. Ideally, you should use the normal water and keep this container in Sun. But, it was very difficult to boil the water using sun light in a rainy season.  So, we took hot water.

The hot water got vaporised and started to move up (Evaporation). We also placed few ice cubes above the fruit wrap to give a cool environment for condensation. The water vapour convert into the tiny water droplets because of the cool environment, this is known as condensation. 

As more and more water droplets are formed, they started to combine. The big water droplets fall down because of temperature change as time passed, this is known as precipitation.  Inu was not interested in precipitation, she happily sad, 'mumma, this is rain'. We kept the ice cubes above the collector container so that all the rain gets collected in the collection container. After some time we removed the fruit wrap and saw the water collected in small container. 

The next day, it was a rainy day and I said what a lovely rainy day it is. And Inu quickly replied, 'mumma, sea water is coming in our city through rain.'
