Flower Experiment

Flower Experiment

During the summer, we have a beautiful wildflower that grows along the side of our road. It’s called Queen Anne’s lace, and each “bloom” is actually made up of many tiny flowers. Queen Anne’s lace is usually white – that is, until we get a hold of it!

Here’s a fun flower experiment you can do with Queen Anne’s lace to show how plants take in water. If you don’t have this wildflower growing in your area, you can use a white carnation from the store instead.

What You’ll Need

White flower

Drinking glass

Food coloring

What To Do

To start, fill the glass with cool water. Add about 10 to 20 drops of food coloring to the water; if you use too little, it won’t have much effect on the flower. Stir well. Place a freshly-cut flower in the glass. Over the next few days, the flower will begin to change to the color.

How it Works

Plants take in water from their roots, and cut flowers take it up from their stems. The colored water travels the same way all the way up to the flowers, coloring them as well.

Variation

You can also make your flowers multi-colored. Though we’ve never tried it with Queen Anne’s lace, we have done it successfully with carnations. To use more than one color, place two water glasses side by side. Add desired color to each. Then, splice the stem of the flower so one piece fits in each glass. The flower will still take up the water and become two different colors!

We used Queen Anne’s lace and carnations. Have you found another flower to use for this experiment?
