Hi everyone!
We all are able to see the source of light. But what are the uses of light except for helping us to see and removing darkness. Let’s explore – I’m using the theater form of dialogue, wherein the dialogue between me and my younger cousin 😊
Me: Your clues are – Sun and clothes!
Cousin: Easy, sun light is used for drying clothes.
Me: True. In the rural areas people use sunlight to dry clay-pots, grass to hay, sun-dried raisins, tea-leaves, etc. The next clue is Sun and electricity
Cousin: Are you referring to solar powered current generators that produce power to move machines.
Me: Yeah, like water motors; electric mills, and even wheel chairs. Ready for the next one – Your clues are transport and Sun
Cousin: Remember the other day we saw the TV show “Grace’s Amazing Machines” where we saw solar powered bikes, cars, trains and yachts
Me: Oh yeah! Then the same clues – transport and sunlight but different usage.
Cousin: It is getting complicated – other than solar powered vehicles? Give me a clue please
Me: The colors change
Cousin: Is it traffic lights? They are also solar powered now-a-days.
Me: Your next clue – hmmnnn, sun and household things
Cousin: That should be easy – torch light, watches, calculators etc
Me: Okay, let me ask you about living beings - Light and food. Can you guess it?
Cousin: Hmmnnn. That’s easy, plants use light to make their food!
Me: Exactly. Plants the sunlight to form food and the process is photosynthesis. The next one is light and health
Cousin: I guess, time for me to give up
Me: Yeah, that was pretty easy I guess – Vitamin D. Sun helps our body get natural vitamin-D. That’s why its important for us to play for an hour in the morning/evening sun. But the Corona virus doesn’t seem to know this!
Cousin: Can’t we use light to kill Corona?
Me: Thanks. That can be a topic for one of my forthcoming blogs
Alright I have got to go. My science teacher is going to take another science class! Bye!
