TIME ZONE CLOCK

We thought of teaching time zone concept to 7^th grade in Isaiambalam school. We started with a question

Adiyaman is travelling to New York to meet his best friend Kabilan from New Delhi. His flight left New Delhi airport on Friday 9.30 am.

His flight took exactly 24hrs to reach New York from New Delhi.

Once he reached New York he was pretty sure that the time should be Saturday 9.30 am.

But when he met Kabilan,Kabilan showed the clock and the time was 11.30 pm. Adiyaman was amazed and confused. Can you find the reason why and help him to understand ?

The conversation took place as follows, as soon as this question was asked

Vishwa: Kabilan’s watch was not working?

Facilitator: No. It Worked.

Jyotisha: The plane was going faster than expected on the day?

Facilitator : No, It went as usual.

Chandrika Piriyan: Adiyaman might be used the time machine?

Facilitators: (Surprised) No.

Then, we introduced the Time Concept. Some questions they raised after understanding

Surender: How many time zones we have in India?

Prem: If a place is located in the middle of 2-time zones then how to find the time zone of that particular place?

Deepika: Is there a time zone clock like the clock? After finding out the answers to the above questions, we planned to make time zone clock as suggested by Deepika. They had to know about the circle to do that. So, we took the kids outside and divided them into four groups. Then we told them to draw a circle and divide it into 24 equal parts.

They drew the circle but said that they could not divide the circle into 24 equal parts in trial-and-error method. We taught about the circle and how to divide it into equal parts. They understood and did the time zone clock.

Chandrika Piriyan made a different design‌. We were amazed at his creativity. We realized that the energy of children is immense and that miracles can be revealed if the right environment is created for it.
