Okay, did you guys ever realize like for example, when you stand near the berbecue pit, or when you stand in front of the iron, when you are cooking/boiling something or even like when your brother is bathing and you enter the toilet and you can feel hot the steam rising up? And isn't it amazing that even though you're not in direct contact with it, like take hot water for an examnple, you are still able to feel the heat?
How could this possibly be explained!
Well, it all links back to the transfer of thermal energy, but how?
How is thermal energy transfered? - you may ask.
Today, what we're gonna learn is mainy about these 3 processes, conduction, convection and radiation!
I won't go into much detail for today, but today's homework would just be to remember the 3 different processes of thermal energy transfer, yeah? :)
Haha, oh and just one last thing that I wanted to say,
you know, these ways of thermal energy transfer can also be applied to animals!
How interesting, yeah? :D
Seriously, believe it or not.
Cool right! Haha.
Example, a bird can reduce the thermal energy transfer from its body during cold weather by fluffing up its feathers.
An African elephant can cool off quickly in hot weather because it has big ears that provide a large surface area for thermal energy transfer too.
Also, polars bears and penguins, they all each have their own special features, adaptations and ways to keep themselvews warm in the cold.
But how?
In each of these different cases, what processes of thermal energy transfer can be seen? Are they radiation, convection or conduction?

Haha, think about it!
And I'll leave you with that :)
