Friday (12/08/2011)

a) Vocabulary Recap.
 We recapped on words learnt example players, basketball, score, team, cheerleader, dance and etc.

b) Flying Equipments.
Teacher: What are the things that can fly?
Class: Birds, helicopter, aeroplane, rockets balloons and etc.
Teacher: Why can an aeroplane fly?
Qian Joe: Because it has wings.
Weei Xiang: Because it has feathers.
Tzen Yu: Because it has engines.
 Planes and other vehicles could fly due to the engines. They fly well because of wings that help at balancing. Birds can fly also due to their vacuumed bones which are light.

c) Air and Balloons.
Teacher: Why can some balloons fly?
Qian Joe: It has a string tie to it.
Tzen Yu: It uses Helium gas which is light.
* Different gas has different weight. The bicycle gas pump as well as our CO2 gas blown out is heavy thus, the balloons can’t fly.
* A few kids came up in front to blow some balloons and they can’t fly.
* Wee Hong mentioned that he has seen some advertisement balloon promoting the banks.

d) The Rocket Balloons.
* Each kid was given a long balloon and then they pumped it using the air pump. It wasn’t easy and so, I had to help them too. Then, they raised their hand up in the air and released the long balloon. It flew really quickly and it was so fun!! It looked as if they are real rockets!
* Hopefully, through this activity; the kids will be motivated to bring 2 empty 1.5litres bottles for our Bottle Rocket Outing next week.
