Room 10 carried out a science experiment to see if daffodils could change colours through the veins in their petals.
First Mrs Maunsell put water into the three cups. Then we cut a little part off the stems diagonally. Second we put the daffodils into the cups of water. Now it was time for the food colouring! Kelemete put the red food colouring into one cup and Jerome put the blue food colouring into another cup. We left the last one plain.
It was going to turn out incredible.
When we got to school on Monday the transformation had been completed. The daffodil in the red food colouring didn’t have red, it had orange in its veins! The daffodil in the blue food colouring didn’t have blue, it had green in its veins! Red plus yellow equals orange. Blue plus yellow equals green. The one with no food colouring didn’t change.
The petals changed colour in their veins because the daffodil sucked up the food colouring. Then it went into their veins. That is called capillary action. What happened to the daffodils was extraordinary and very cool. The daffodils showed us how they sucked up the water through their stem to their petals.

WOW!That is so cool
ReplyDeleteSeeing if daffodils will change color in food coloring is the best idea ever!
It sounds so exciting when you found out that the daffodils had changed colors.
Why did you chose daffodils? I know that the are nice but maybe you chose another flower.
I think that you must of thought about a lot and that it was a great idea.

That looks really amazing. Maybe you could try different colours. I wonder how long it would have taken to change the colour of those flower ?
