Learning happens naturally, you don't need a next textbook, a curriculum, a teacher, a classroom and a set time. TS : Amma can I oil your hair?
DN : Yes, please.
TS : Amma, why is oil sticky and not like water?
DN : come on, let's find out. Go get some liquids you find around the house.
TS : Amma, this is all I could get - water, milkshake, oil and honey.
DN : Touch and see how each one feels
TS : some are running, some are not running.
DN : Yes, each one have their own weight, texture, color and smell.
TS : Amma can I mix them.
DN : why not? (after 10 minutes)
TS : oil is not mixing with water!! DN : Yes, each have a different weight, that's why they don't mix. (how can I explain density and attraction of molecules at this stage?) (after 10 minutes)
TS : No Amma, oil and water can mix.
DN : No kannu, it can't
TS : come see here, it mixed.
DN : Yes kannu, but how is it possible? Let me check on the Internet.
Emulsification - oil and water can mix on sever agitation.
Yes, Thanvi, it's true, it mixed because you kept on stirring. (Next time I should make mayonnaise and show her) Thanks for teaching me this today. I learned a lot from seeing you play.
TS : hmmm.
