The weather is warming up, the sun is starting to shine (sometimes) and flowers are starting to bloom! All of this makes a wonderful combination to do some science! In this project we’re going to create rainbow flowers.
What you’ll need:
- white flowers, like carnations
- small jars
- food coloring
- paring knife or scissors
- adult assistance or supervision
Step One: Trim the Stems
Cut the stems of the flowers so they are 10-12 inches long. (Have an adult help!) Using a sharp knife carefully cut a 6 inch slit through the bottom of the stem. Remove any large leaves. Be sure to keep the cut edges moist since exposure to oxygen will make the flowers wilt at a faster rate.
Step Two: Add Dye
Fill your jars with water and add between 10-20 drops of food color (or more depending on your preference). Place each separate stem end into a cup of colored water. Prop up the flowers so they don’t fall over. We had some fancy mason jar covers, but tape should work as well to help prop the flowers.
Step Three: The Waiting Game
Place the jars by a window and hopefully you will begin to see the first hints of color after a few hours, but wait 24 hours to see an even more dramatic change.
Flowers go through a process called transpiration, where it releases moisture into the atmosphere. As moisture is released, more water is pulled up through tiny tubes in the stem called xylem. Water molecules have the tendency to stick together, so as one water molecules leaves the flower, it brings another one up with it.
Did you like this activity? Then you might be interested in our single-day Spring Break Camp!
Turtle Bay will be offering single day camps April 11th – 13th for children 7-10. Campers can register for one, two, or all three days. Each day will be different from the next as we cover matter, energy, and forces. All camps will feature hands-on and self-led activities that encourage collaboration and innovation.
Tuesday, April 11th – Magnificent Matter
With all things hot and cold, campers will discover the states of matter and how they’re important to us. Some activities include changing milk into one of our favorite desserts to stacking liquids on top of each other!
Wednesday, April 12th – Energy in Action
Campers will explore the sights, sounds, and properties of energy in many forms. From discovering the power from the sun to watching the effects of sounds, we will be learning all about the power or power!
Thursday, April 13th – Fantastic Forces
Though our superhero forces may be lacking, there are still many super forces to be explored! Campers will check out the unseen forces of our Sundial Bridge and see if they can explain the mystery behind magnets.
Whether you have enrolled into one of our camp programs before, or if this is your first time hearing about them, we invite you to check us out! For additional information and registration forms, visit www.turtlebay.org/learn/camps. We have a limited space, so hurry!
