Colored flowers science experiment

Colour a White Flower

Colour a White FlowerHow to make color changing carnations? Making of flower bouquet required many flowers with different colors. These colors make the bouquet more attractive and presentable. But if you have only a large collection of white flowers with you, then it is difficult to make such  a beautiful gift. Here is the easiest remedy. After you complete this ‘colored flowers science experiment’, you will be able to make multi-colored flowers out of white flowers. All you need in addition to the flowers are some food colors from your kitchen, a vessel to keep the flowers, and some water. This activity also helps you to study how water travels through flowers and plants. After the completion of this experiment, you will be able to answer the following questions.

  1. How to make color changing carnations?
  2. How does food coloring affect flowers?
  3. Why do flowers change color in food colors?
  4. How do flowers absorb colored water?

Let’s answer the first question by performing our colored flowers science experiment.

Try it yourself

You need:

  1. White flowers – As you required
  2. Food coloring – Any color / colors
  3. Containers
  4. Water

What next?

Step 1: Take the containers and fill with water.

Step 2: Add a food color each to each containers. Try to make concentrated solutions of different colors.

Step 3: Cut the flower stem of each flower and put it in the colored water. Now absorption of colors through the stem started.

Step 4: Leave the container for a  few hours. Check after every 2 hrs. After 5-6 hours colors will appear at the tip of the flower.

Wait for a day to complete the process.

Step 5: Over the next day you will see that color is appear in all petals and even leaves. Now take the flowers and start to make a wonderful bouquet with it.


Now you can make a beautiful flower bouquet. Make one and present it to your dear ones or decorate your walls. But do you know the logic of ‘Colored flowers science experiment’? You will understand the logic as we answer the remaining three questions that we mentioned earlier in this experiment.

How does food coloring affect flowers?

When you dip the stem of a flower into a container with water-based food color, the stem carries water through the pores of stems and reaches the flower petals. The water particles that reached flowers and leaves of a plant will later evaporate to escape into air. The water with food color that was carried to the flower petals will affect flowers by changing its color.

Why do flowers change color in food colors?

Flowers change color due to transpiration process when they are dipped into food colors. The food color can change the color of petals, stem and leaves, but the visibility of color change on white petals is more prominent than on other parts of the plant.

How do flowers absorb colored water?

Flowers absorb colored water through a process called transpiration. This process lets plant roots, stems, and other parts to absorb water. Try this experiment at your home and let us know your results.

What modifications you can try on ‘colored flowers science experiment’?

You can try it as a project where you keep three pairs of white flowers. One pair of white flowers can be immersed in colored ordinary water. Another pair in colored salt water. And the last pair in colored sugar water. With this variations, colored flowers science project will help you understand the effect of sugar and salt in the absorption process of flowers.
