Baking Powder and Vinegar Play

Today we introduced a little science experiment into our daily activities. I set a three year old the challenge of finding out what happens when you mix baking powder and vinegar.  He had great fun experimenting with this and definitely proved that science can be fun! 


I added some food colouring to clear vinegar and provided some pipettes and a baster to enable the vinegar to be added to the baking powder. Cautiously he began to add the vinegar using the smaller pipettes. Initially he was fascinated by the colour changes when the vinegar hit the powder but then he noticed the bubbles, putting his ear closer to listen to the resulting fizzing sound. 



To see the reaction better he began to use the bigger baster and this gave a much better bubbling reaction and produced some nice colourful results.
