I just love this colour changing flowers science experiment! It is simple to do and the kids love seeing the flowers change colour. We think it’s the perfect science action for spring!
I made recording sheets that kids in preschool and early elementary may use to reveal their observations. Don’t forget to scroll to receive them.
Color Shifting Flowers Experiment
We love this one and a fantastic science experiment didn’t disappoint. It was really neat to see the flowers change colors. You should definitely give this one a go if you are interested in finding a science action to try this spring!
- Free printable recording sheets (button to get at the bottom of the article)
- White carnations
- Liquid food coloring in an Assortment of colors
- To start you will want to trim down the stems of the flower so they match your glasses or cups.
- Add water to every cup.
- Then place about 10-15 drops of food coloring in the water and stir around a bit.
- Insert at least one carnation to every glass of colored water.
- Check about the blossoms every couple of hours and watch any changes.
Observing the Flowers Change Color
We did so colour changing flower experiment and we began to see changes within a couple of hours. Some of the blossoms started showing faint stripes of colour along their petals.
By the next morning, the majority of these were more colorful. The blossom in the purple water did not appear to be carrying in water so I trimmed the stem a little more and it soon began showing color.
The colour was even more vibrant, this day.
We chose to see the flowers. They did receive a bit brighter than the pics over, but never saturated in the color.
The next time we intend to attempt if we get more saturated colors food coloring to determine. We also determined that roses will try and determine if a person takes on the colour better.
There are a number of ways. You can try doing different blossoms simultaneously. Or you can try various amounts of food coloring.
How Do Plants Drink Water?
Water is drunk by plants from the ground up through their roots. The water travels up the stem and into the petals of the blossom. Though, our blossoms didn’t possess roots anymore they were still able to pull up water from the cup up and into the stem through the blossom to the petals.
It is via capillary action that crops are able to resist gravity and pull up water and into blossoms and their leaves.
To read more about this particular action, have a look at this amazing walking water science experiment!
We hope you will give this enjoyable colour blossoms science experiment that is changing !
