Science Experiment: Dyed Flowers

Posted Saturday, June 09, 2012

Science … we love it. Many times when we have gone past the flower area at the grocery store we smell the sweet scent of fresh roses and dainty daisies ... the girls have been fascinated with the flowers that are in an array of colors that are dyed but yet they know that they are not naturally that color … and have wondered “how do they do that?”

Well, we made it our science experiment last week! So now they have a much better understanding and can visualize how the flower petals changed colors.

Steve Spangler Science shares a great tutorial on dying flowers, in addition to other experiments he has done…but most importantly the details and why they work make sense on his website that kids understand.

Our science experiment was over a course of several days. We started out using some older daisies that we had purchased later the week before. We recut the bottom of the flower stems and placed them in the colored water glasses. The older flowers did not dye as well as we had hoped, but we knew that might be the case going into the experiment. A few days later we purchased new flowers and this time they did much better and the color was obvious.
One question the girls had asked was how soon do you think we will see the color in the petals? Within two hours, it was amazing to see the colors showing in the white petals. By dinner time, the flowers were fully dyed and in a brilliant shades of yellow, blue, red and green.

We even wondered if certain colors would dye the petals quicker than others. It seemed to us that the blue and the green food coloring dyed the white petals the quickest. I know in the printing world, that when you print with blue ink, it takes longer to dry than any other color just due to the pigment. I know it doesn't relate to the experiment but it is an interesting fact that makes you wonder about inks in general.

Do you have a favorite science experiment book/curriculum that you use? Please feel free to comment below or send us an email. We are always enjoying and reading science books and would like to share with other families in the journey of learning.

In addition to the Steve's website we also enjoy the following:
  • The Magic School Bus series. We will reserve DVDs and library books from our library and/or watch the various topics that we are studying via YouTube. Last year, I purchased The Magic School Bus Science Experiment books that take each of the episodes and relate it to an experiment/participate in an observation. On the MSB website they also have a Parent/Teacher section that is very helpful. Ms Frizzle and the gang are always a hit with the girls. I must admit...I love the series too.
  • I recently have exchanged emails with a mom I met through a workboxes group. Via our email workboxes group, Colleen shared that she has written several books, with one particularly focused towards science. Colleen has a blog called Raising Lifelong Learners as well as her writing website called Colleen Kessler. I strongly suggest you visit her blogs to learn more.

As we prepped for our experiment we talked about how flowers/plants drink water to survive, how the flowers use their roots, and the water travels up through tubes in the stem. By coloring the water, we will then see the water move up the stem and into the flower petals over a course of a couple of hours.

Neat experiment! Thanks for the links, I'll be sure to check them out. Do you homeschool?
