The most exciting part of the day for our children is hands own activity. When
teacher declared in the class regarding conduct of “water solubility”
experiment as small group activity in science centre, they could not contain
their excitement.
They helped the teacher in collecting the material.
Water, sugar, tea dust, plastic coins, glass and spoon.
Before starting the experiment, teacher asked them about their previous
knowledge on solubility. For the younger one solubility is nothing but
disappearing in water.
Teacher asked their choice of substance to be added to the water first. Sugar!!
the answer was unanimous. They added sugar and stirred the water. They used
the sand timer to see the time. The sugar “disappeared in water” – Yes it is soluble!
The next one they wanted to add was tea dust. Now this was tricky. Children
could see the tea dust in the water but they could also see how the colour of
the water is changing. However the tea dust was not soluble.
The last part of the experiment was to add plastic coins. Children predicted
that the plastic coins will not disappear (they meant it will not dissolve). They
added plastic coins to the water. Yes, they were right, the plastic coins are not soluble in water.
Yes, children are natural born investigators. Preschool years are an ideal time
to support and strengthen the inborn dispositions of all children to observe
and to investigate their experience – the reason we incorporated the project
approach in our early childhood curriculum!
