Green Daffodils
Posted: Thursday, 31 May 2007 |
The bairns have been studying how plants function as part of our Growing Together topic. Here's one of their reports:
We took three daffodils and put them in water with blue food colouring added. They should change over time as they take their nutrition.
We put food colouring in water that we gave to the plant.
They quickly started to change colour.
As you can see water with food colouring in it will change colour if fed to the plant. The water goes through the plant's veins and changes its colour.
The plant had absorbed water and changed colour.
When the plant died we cut it open and looked at where it had absorbed water and changed colour. But the seeds in the ovule did not change colour.

I'm green with envy. I've drunk a lot of blue Kool-Aid and nothing has happened.

Interesting stuff. The effects are quite striking and it's odd to see how the blue reaches some parts and not others. On a more frivolous note, you could do a selection of colours and end up with a very unusual bouquet.

What a cool idea, I think me and Mum might try to make some green daffodils too.

So that's how the Co-op 'transform' their chrysanths...
