May ’16

We did an experiment to see how a stem draws water up like a straw. We put some food colouring in some water and put a white flower in it…

We waited a few days and….. NOTHING HAPPENED!!! So we’re trying it again – watch this space……………

 

So here’s are second set. Some of us poured a little more food colouring in than others….

Then after two days, the colour had spread even further….

If you look closely you can see some of the petals have changed colour – now it’s really working! 🙂
