We had a great afternoon finding out about the water from our partners' countries. We carried out the suggested experiments very carefully as follows:
a) Physical aspects: colour, smell, clarity, pH response.
b) Observation under a microscope
c) Adding violet ink and placing a flower in the water.
d) Mixing the water with salt, sugar, flour and oil, and observing the results.
The children were most amazed by the pH reaction: they found that the water from Lake Puula was acidic! Is this true? And the water from Cyprus appeared to be slightly alkaline. Is this also true?
