Color Changing Rose Experiment: A Little Blue and Little Yellow Activity

It’s week three of the Preschool Book Club Series and this week we are exploring Little Blue and Little Yellow by Leo Lionni. The simple tale of two friends, little blue and little yellow, encompasses so many learning opportunities regarding friendship, emotions, family relations and of course color recognition and color mixing. This week we will be combining our reading of Little Blue and Little Yellow with a Color Changing Rose Experiment to make our very own “Little Blue and Little Yellow” rose.

AREAS OF DEVELOPMENT ENHANCED BY COLOR CHANGING ROSE EXPERIMENT

literacy development
color recognition
color mixing
scientific exploration (forming hypothesis, observing changes, parts of a plant)

HOW TO CREATE THE COLOR CHANGING ROSE EXPERIMENT

Begin by adding a couple of inches of water to 2 mason jars or cups (this will be for 1 rose). Add a good deal of blue and yellow food coloring to the water, 1 color per jar. The blue water should be a very dark blue and the yellow will look orange.

This step is definitely an adult job. As children observe you name the different parts of the flower you are working with.

observing the rose in the color changing rose experimentWe talked about how when a flower drinks water the water goes up from the bottom of the stem and travels to the top. What do you think will happen to the rose if we use blue and yellow water? Using their knowledge of color mixing my children were certain the flower would turn green. Time for my little scientists to observe their experiment and see if their hypotheses was correct.

“MAMA, LOOK!” This was my startled good morning the next day that had be racing to the room as my daughter screamed at the top of her lungs. Preparing myself for some horrid sight I was pleasantly surprised to see that my daughter’s exclamation was pure excitement coming from a little scientist full of joy! It’s blue and yellow!

the results of the color changing rose experiment a little blue and little yellow experimentAdmittedly I was just as excited as they were! We talked about how different parts of the stem are responsible for different rose petals. The part of the stem that was drinking the blue water was responsible for the blue petals and the part of the stem drinking the yellow water was taking care of the yellow flowers. We kept our flower out for about 4 days before it started to wilt. We will definitely be exploring more ways to combine literacy with scientific exploration after this successful activity!
