P19 - Why do we see a Rainbow?

One lazy afternoon I was not in a mood to do much so told her that lets grab some book and read. She picked a book gifted by her Bua, 'Little Kids First BIG Book of Why' published by National Geographic Kids. 

Thank you Gudia Bua!!

The book has a discussion about why do we see a rainbow. We studied and repeated the experiment shown in the book so thought of sharing the same with you all. 

First we discussed that Sunlight is made up of different colours Red, Orange, Yellow, Green, Blue, Indigo, and Violet. We discussed this while doing the experiment about Sunlight and Colours. We shared that experiment in my earlier post. 

I asked her when do you see a rainbow. 'If its rainy and sunny at the same time we see rainbow', she replied. I explained her that Rainbows are the sun light separated in different colours. When it rains we have water in the air. When the sunlight hits the water droplets in the air, it gets scattered and we are able to see the beautiful rainbow.

Next, we did an experiment to make a rainbow with sunlight and water.

What you Need: 

        - A glass filled with water

        - Paper

We placed the glass of water on the edge of a windowsill where the bright sunlight was coming and placed a paper on the floor below the glass. If you are lucky, you will see the rainbow in the first place. We were not lucky that day so we had to move the glass a little to see the rainbow on the paper.

Inu loved this experiment. Whenever its rainy and sunny both, she search for a rainbow.
