This is a great science experiment that is sure to have that ‘WOW’ factor we want from kids. It teaches them about the life cycle and that plants need and draw water for survival.
Here is how it’s done.
Begin with the following key items for this experiment.
Add 10 drops of food colouring to each of the cups then add 1/4 of a cup to each cup. Mix.
Place one stalk of celery into each of the cups.
You’ll notice that the colouring begins to draw up the celery almost immediately.
I placed each cup in a container to hold them still and fastened each cup together using sticky tape.
Waiting, waiting, waiting.
Possum gets to enjoy some left over celery.
TA-DA!!!
The celery leaves have changed colour because of the water. This is after 12 hours.
Yellow
Green
Red
and Blue!
Enjoy
How does it work?
I’m growing celery plants from the inner core of stems, in water. Not to eat, but to just enjoy their lovely green-ness – the stalks turn from pale to darker green. They now have nice roots and I’ve been thinking of planting them. It might be fun to water them with a bit of dye added. Thanks!
Oh Karin that sounds absolutely wonderful! I love that you’re just doing it to enjoy it’s loveliness. Here is another post that you might enjoy. https://laughingkidslearn.com/how-to-grow-lettuce-indoors-with-kids/
