We armed ourselves with crayons, pencils and paper. First off we decided to do some bark rubbing. This wasn't as easy as I thought it would be as most of the trees seem to be quite smooth. But we found a rough one and tried it out.

So we then thought we would try leaf rubbing. Probably the wrong time of year for this as very few trees have leaves on them just yet. But we found a few to try with.
|this worked better than the photo shows|
the fern leaf worked well.
So then we decided we would pick some flowers, these were picked on private land and so it was done legally. We picked twenty snowdrops, enough to split into four of five colours and a few daffodils.
So when we got home we set up our experiment.
We got four small bowls and Bob chose four different food colours.
Bob added water to the bowls and measured half a teaspoon of food colouring into each.
I then got Bob to split the snowdrops into four piles. Division is something he has not covered in his education yet so I got him to put them into four piles one at a time. Experiments can be educational in more than one way.
We then discussed what we expected to happen and why, Bob learnt that the flowers would be thirsty and that when he is thirsty he drinks and so the flowers would drink the water up and as the water was coloured the flowers would change colour.
So we left the flowers over night, came down this morning to look at them
and for some strange reason every one of them is still white!!
Not a hint of a tint anywhere - would somebody like to tell me what went wrong?
I decided to freeze the coloured water in ice cube trays and next week we will do experiments with them,
Ok having read some nice peoples comments, I added a chrysanthemum and a daffodil to some blue food dye, and 30 hrs later I have these.
|I really like the daffodil|
I mentioned on twitter that I had also added snowdrops to the blue gel colouring and they had changed colour 36 hrs later, sadly they had also wilted but as requested here is a picture of them. It is out of focus but clear enough you can see the result.
