One day last week, my son came to me and said, "Mom, you have to do this with your kids at school!"
With determination, he taped it up on our morning message board for all of the children to see, along with a message to, "Have fun!" Well, how could I not do it? Once the children saw it, they all wanted to complete this experiment. We ended up using white carnations as they were more easily available. If we do this again, however, I will be sure to get the roses because it was a challenge slicing the stems of the carnations... In any case, here is our modified version (which has produced no less enthusiasm!) :)
 |
| Colored water and carnations. |
 |
| Some children drew their observations on the first day... |
 |
| On the second day, we were greeted with this! Blue seemed to have worked the best, while green was hardly visible. This did not seem to bother anyone - they were so excited... |
 |
| This is an example of a student's 'after' drawing. |
If you want to try this with a rose, check with your local florist and see if they have any water picks. They are small plastic tubes with a rubber cap on top. Fill the tubes almost to the top with very concentrated food coloring/water solution. Any white rose will work, but the one that is most commercially used for the rainbow roses is a variety called Vendela. Carefully using a very sharp knife, split the stem into quarters and slide the water picks on each of the pieces. Leave the rose for a day or so and it will make a rainbow rose. :)
