Today we are going to learn something very interesting.
Do you know why we yawn?
Well dr Binocs is going to explain this to us in his wonderful way so that everyone understands.
Yawning is when our brain is tired; we have to send more oxygen to the brain.
It is something that is even contagious as we find that when we yawn others will also start.
It is when we breathe through our mouth and nose and we try and get more oxygen to help the brain.
How many of you have been in trouble at school for yawning. I hope not many.
It is normally when we spend too much time doing homework and playing a lot of games on our x-boxes that the brain does get tired.
But rather watch the video and you will understand it so much better.
I hope you enjoyed it and have a wonderful day from me here at the Wild Coast.
