He had also made some some water blue by boiling some red cabbage leaves. This water was put into glasses. He then used the balloon and a straw to blow the carbon dioxide into the water . The carbon dioxide caused a chemical reaction that made carbonic acid and turned the water a beautiful purple colour!
The younger two had great fun taking turns to blow through straws and change the colour of the blue water to purple too!
We also got a great resource for our bird studies from my sister and today we used chicken bones to make up a chickens skeleton.....real hands on fun! It was great for the children to see how it all fits together.
