Have you ever observed the shadow formation and how it behaves? children.

What do you notice in the image given below?

Are two people walking ?. And their “shadows”.? There aren’t many people who have not heard of the term shadows. But why and how are shadows formed.

To understand shadows, you will first need to understand the sun light makes shadows.

Children, observe the images and discuss how the position of sun and shadow varies from time to time in a day.

In last image, the sun is not there. There are stars, the moon and dark sky in the night. Where was the sun?. Behind the earth. Next day we begin with “Good Morning” and it goes on. This cycle is called Day−Night cycle. It takes one day to make one revolution. It revolves 365 times to go one round around the sun. Which means 365 days. This we call it as one year. We celebrate “Happy New Year”.

In the above picture which will be the fastest transport.? Which will be the slowest? Think,

How do you measure the difference in time?. We would use clock for measuring time.
