Sink or float experiment.

Monday (16/02/2008)

a) Water has weight.
That’s right because when we filled the balloon with water, it was heavy. The more you filled, the heavier it becomes. However, what are the things which are heavier or lighter than water.
Thus, I pasted a chart. We talked about some vocabulary. We included spoon, stone, apple, potato, rock, straw, nail, leaf, ping pong ball and also tennis ball.
I got each kid to write the list onto the chart.
Thus, they would complete the chart as we do the experiment at the garden.

b) Sink or float experiment.
* The kids were excited to see a swimming pool full with water. We pasted the chart next to the pool. I asked each individual to put the things in the pool. Before that, we guessed the possibility.
* As we dropped the things, the kids were excited. Then, we recorded onto the chart. I was surprised at how good the kids’ observation. They could recall even without looking at the pool again.

c) Let’s play and swim.
We had a mobile swimming pool filled with water. There was also a smaller one for the kids to play with their paper boat.
They enjoyed tremendously and could actually play with one another tolerantly.
The girls preferred to play with the paper boat.
Next, I sprayed the hose into the air. The kids looked up. Yun Zhe at once thought that it was raining. However, they were happy to see me spraying the hose into the sky.
We played for just about 5 minutes fearing some kids might catch a cold.

d) Is rain water safe?
In fact, no! We recalled the water cycle. Then, came the factory. Because they release poisonous gas, they evaporated and mixed with the water drops in the clouds.
As they condensate and precipitate, rain started to fall…..that’ acid rain which is dangerous to us.
Thus, playing in the rain will cause us fall sick.
