Flower Science Experiment

This is a classic flower science project that everyone must try at least once in their life because it so cool! It is such a vivid example of capillary action at work.

Start out by filling four glasses with water and 30 drops of food coloring – use any colors you like.

We’ve tried this experiment with carnations before and just haven’t had the amazing results as we did this time. I highly suggest using gerbera daisy flowers for this experiment.

Start by trimming several inches off the bottom of all your flowers. That makes sure the pores are open and ready for capillary action to occur quickly.

If you would like to really WOW your kids I suggest using a utility knife, carefully cut  the flower stem in the middle from the bottom up about 6″. This will allow you to color one flower with two colors!

Place one flower in each colored water cup. Take the flower whose stem you cut in half and put one part of the stem in one color and the other part of the stem in the other colored water. This flower will be drinking water from both the colors which will result in the food coloring going into different parts of the flower and even combining at some spots for some beautiful color mixing.

Now watch – within a couple hours, your kids will be AMAZED at what they see in this flower science experiment.

So besides the “Wow effect” your kids are about to experience, what is the science behind what’s going on?

When plants are in the ground they get their water by pulling in up their their roots. Once inside the flower stem, tiny tubes called xylem take the water to the plant’s flowers and leaves. The flower stem is like you getting water through a straw! This experiment allows kids to see that happen because the flowers will drink the colored water by pulling it up their straw, the flower stem. Kids will know the water has reached the flower when the petals start showing the colors in the water.

Splitting the stem allows the flower straw to pull up two different colors of water to two different parts of the flower through capillary action.

Within an hour, you will start to see the leaves are turning the color of the water they were resting in.

Look how stunning this flower looks after drinking blue colored water all day. Cool right?

Look how cool the flowers look when you split you stem and make bicolor flowers. Super cool, right! If you look carefully the area between the yellow and the blue looks a little green. There is some color mixing taking place as well in this flower science project.

Some of our flowers didn’t color exactly symmetrically, but then again, we probably didn’t cut the stem perfectly even either. I think they came out so cool! Make sure you see all our Kindergarten Science Activities!
