Try this - it amazes the kids!
Get a nice bunch of white flowers with plenty of open buds - carnations work best.
Half-fill some jugs/glasses/anything that'll hold water and support stems and add a good squirt of food colouring to each one, making sure each is a different colour.
Add your flowers, wait a couple of hours (that's all it takes), then check out your 'new' blossoms!
For even more 'WOW' factor, split a stem to approx 6 inches up and place each half in a different colour jar!!!
Enjoy!
Now here's the science bit.....:teacher:
To teach the children how this works, give them all a straw and a little bit of liquid to drink, as they suck explain that this is exactly the same way that the flowers drink and feed their petals and because the water was coloured it made the flower heads changed colour too. Reaasure those who are worried that their hair is now going to turn green/blue/red etc!!
