This week has been pretty busy. I had to finally embrace the whole “being thirty” thing, but it has been great thus far. Neyland and I did a lot of fun projects this week. She was a particularly good girl this week and worked really hard on all her homework, chores, and even memorized several scriptures from church. In return, we had a lot of fun outings and activities to reward her excellent work. For “Science Experiment Tuesday,” I pulled an old project out of my hat from when I was a kid. We decided to make rainbow flowers!
This experiment is one more geared toward preschoolers and older kids. The experiment isn’t instantaneous, and therefore won’t hold the attention of younger kiddos. Neyland is really into wanting to know how things work, so it was a great demonstration for her. We started off with a trip to Grandma’s flower shop to pick out the flowers for our experiment. The type of flower isn’t super important. We chose some daisy poms because they hold up well at room temp, and are overall, pretty resilient. Some of the more delicate flowers may wilt after a few hours. The big thing is to (obviously) get WHITE flowers so your little one can observe the color change.
We also got three different stems of daisy poms. Each stem has multiple flowers, so we would get to see more action.
Next, pull out your food coloring and a few glasses of water. I let Neyland choose what colors we would make in each glass. It was also a good way to review which colors can be mixed to form other colors. She chose to make: Purple, Blue, and Green.
We mixed up the colors, trimmed excess foliage off the stems, and then finally snipped the stems to freshen the ends. One trick to note is that the shorter you trim the stem, the faster the experiment will yield results. The colored water has a shorter distance to travel. Also, by getting rid of the excess foliage, you limit other areas for the colored water to be carried to. After cutting the stems and placing them in the water, we set them near the window.
Within an hour or two we were already getting visible results! We used this to discuss how plants draw up water and use sunlight to make energy and grow! It was an exciting thing that she got to check on for the next few days. Our “blue” flowers yielded the best color. The green was very subtle and not easily noticeable. The purple was very interesting. It yielded some purple spots, some red, and some blue. For whatever reason, the colors separated back out somewhat.
This is a super easy and cheap experiment to recreate at home! Even if you have never done it before as a kid. You probably have food coloring in your pantry, and you might even have some white flowers growing out in your yard! Get out there and have a great time with what you have!
- White flowers (that remain sturdy at room temp) – Rec. carnations, daisies, poms
- Variety of food coloring
Fill the glasses 3/4 full of water. Color each glass of water with a different color using the food coloring. Trim excess foliage from the flowers and snip the end of the stem before placing it in the water. (Snip the stem IMMEDIATELY before placing it in the water) Set the glasses in a sunny spot and monitor them periodically for changes. You can keep this experiment going for a few days! Just remember to trim the stems on your flowers fresh each day to maximize the amount of water they take in!
