Children love the magic of bubbles on a summers day. This week the preschools challenge was about who could blow the biggest bubbles and who could catch the most bubbles. Amongst all this, one big question in their curious minds was, ‘ How does the bubble form?’
I ( Rachel) explained to the children that the bubble is a thin film of soapy water and most of the bubbles are filled with air.
Then we made different bubble solutions using different detergents, water and glycerin. The children experimented blowing the bubbles with different mixtures.
We succeeded in making the big sized bubbles, but learnt following facts about making better bubble mixtures through experiments and looking for the information in the internet.
· Using distilled water is best for making bubbles as the tap water contains heavy metals that hinder the forming of stable bubbles.
· We also learnt that humidity is the key for the best bubbles. Wet, sticky and muggy days are the best conditions for making good bubbles.
· Also we figured out that at dusk as the sun sets or at dawn when the sun rising is the best time for the bubbles.
· We also learnt that direct sunlight, dusty air, strong breezes ruin the bubbles.
In future, we are going to make the bubble mixtures using the distilled water. We are going to do other experiments like freezing the bubbles using the dry ice, coloured bubbles, bubble paintings – to name a few based on the resources available to extend the childrens interest in bubbles. This coincides with the exploration goal as the children are experimenting with different materials to enhance their learning.
