FREAKY SCIENCE FRIDAY.....
Friday is science experiment day at Sarah's....
Last Friday, Sarah and Willow had fun with science experiments....
First they mixed food colouring in milk with dish detergent....
This lowered the surface tension and made the colours all spread out...
Willow was fascinated with in and wanted to keep adding more detergent...
Mixing colours... |
The idea was to see the sultanas rise and fall...
They were producing carbon dioxide bubbles which were attaching to the sultanas and making it rise and when it got to the top of the glass the bubbles would all burst and it would drop again...
Willow found this fascinating...
putting the baking soda into the water.... |
watching it all froth up... |
watching to see the sultanas rising and falling... |
She has such an inquiring mind..
This is such a beautiful age....
