Labelling water

Tuesday (10/02/2009)

a) Collection of variety water
We recalled the names of the 10 types. However, the kids decided to cancel the drain water as it is dirty and the bacteria might be harmful to the kids.
They analysed the colour of the variety water. They saw that rain water was as clear as tap and drinking water. The sea water was very dirty. Immediately, Jen Ning said people throw rubbish into the sea.
They saw that sugarcane and the pond water was almost the same colour. However, sugarcane was darker green.
When we wnet down to scoop the fish pond, there was moss and algae which the kids thought it was motion??! This is related to ecosystem. They learnt “moss”. However, it is so difficult to see the fish.

b) Labelling the water.
In pairs, they labeled a paper cup with paper. We don’t want to mix up! I ensured that the stronger kids to spell out the letters and while the other kid to write the words.
Then, they pasted.
They learnt that a tablespoon is 10ml. So, we wanted 4 tablespoons. Immediately, Eugene, Song Chuan said that will be 20ml. Yes, we must have 20 ml of different type of water in each cup. Altogether, we have 9 cups.

c) To observe the result.
As, it was already 5.15p.m., thus we decided to place the cups tomorrow noon and to analyse them at 4p.m. when our class begins.
Meanwhile, I got the class to think of the thematic they wanted to do for this month.
