This experiment is a great lesson of “patience” to give to your children, of course beside teaching them about flowers and osmosis. But before going that deep let me tell you it’s also a great fun for the whole family!
Very easy set up; begin by filling the vases with water and desired colors. We used roses and daisies for the experiment. Give a fresh cut to the flowers before placing them in the colored water, it helps for a quicker absorption.
As the flowers drink the colored water, they will start changing colors (due to osmosis effect, in simple words moving water through the stems to make it more comprehensible to your kids as the flowers need to drink). The change won’t start before few hours.
Our first observation was 6 hours later.
The roses were more colored than the daisies. Not all flowers react the same. Nady is so into experiences nowadays, he expects to do one every day after school. I am sure he is fascinated with the outcome thinking it’s magic more than science. I don’t blame him, i would like to believe so also, it brings more fun to the experiment 🙂
Honestly i was very impressed with his patience, personally i wasn’t. It was a good exercise for me too.
Last observation was 48 hours later. Here are our beautiful flowers!!
You can leave the flowers in the water as much as you want, the colors will be certainly brighter. It all depends on the patience of your children.
