When these forces work together and become stronger than the force of gravity, water, nutrients, and even food dye can work their way up through the plant stem to the petals and leaves of the flower.Need to Color Online Free? Visit How, you ask? A little thing called capillary action, which moves the water (and anything in it) through the narrow space of the stem via cohesion (water molecules sticking to each other), adhesion (water molecules sticking to the molecules of the plant stem), and surface tension (the intermolecular attraction that pulls molecules of the water inward from the surface resulting in lower surface area). We know that plants need water to survive, and while it is generally the roots that “drink” the water for a plant, even cut flowers can survive for a little while if placed in water. We plan to play around with roses and daisies next. The more saturated the dye, the more vibrant the colors.Įxperiment with other types of white flowers to see if there is a difference in the vibrancy of the colors, the time it takes for the colors to reach the petals, or if some flowers show no change at all. Tips for Making this Experiment a Success:Ĭut the stems short enough that the flowers are just above the top of the cup (this provides a shorter distance for the water and dye to travel to the petals). Try This: If you want to take your experiment further, try carefully slicing a stem in half to place one half in one color and the other half in another color. TIP: Avoid using dull tools to cut the stems since this can hinder their ability to uptake water.Īdd water to the glasses (about ½ a cup should do the trick depending on cup size).Īdd about 30 drops of food coloring (or more) to the cups and stir.įor orange, add 15 drops of red and 15 drops of yellow.įor purple, add around 20 drops of red and 10 drops of blue.Ĭheck the flowers every couple of hours to observe any changes.Īfter at least 6-8 hours, record your observations (we waited about 24 hours to record the results). This angle increases the surface area, which allows more water to travel up the stem. My kids love rainbows, so we did red, orange, yellow, green, blue, and purple.Ĭut the flower stems at a 45-degree angle to fit the cups. Make your hypothesis! What do you think will happen to the flowers?Ĭhoose which colors you want to try. With supplies in hand, let’s get started! Thankfully, this particular rabbit trail involved a pretty easy experiment that required very little prep and supplies. When I can say yes to his curiosity and head down a fun rabbit trail that will lead to both fun and the learning of concepts he can apply right away. I absolutely love these moments in our homeschool. I told him it was certainly worth a shot, so we purchased some white carnations and planned out our experiment. I nodded, which then prompted him to ask, “Can we do that with food dye?”. He looked a little baffled and asked, “you mean like with food dye?”. He asked me how they found such bright flowers, and I told him they used dye to make them that way. He likes to use the Seek app on my phone to identify what type of flowers they are and then jot them down or draw them in his nature journal.Īfter one such walk and journaling session, we stopped by the local grocery store, and he spent some time admiring the brightly colored carnations on display. My older kiddo has made it a habit of searching for new flowers on each hike and neighborhood walk we take. There’s something so special about watching the vegetation come back to life as the days get longer and warmer again.
