![]() ![]() Cool, right? These beautiful flowers, at the end of the experiment, found themselves in some fresh clear water and on display in Possums room. We mixed them make the purple colour initially, but you can see how they separated above. We also observed that the flower seemed to be able to separate the two food colours. Still amazing, but less vibrant in comparison. One thing we did observe was that the flower in the purple coloured water didn’t absorb quire as well as the others. Possum loved watching the changes over the course of the week. It did seem like we had magical colour changing flowers. I’m sure you’ll agree that the results we experienced in the colour changing experiment were absolutely amazing. Amazing! Every three days I snipped off a bit of the end of the stem, which kept the flower fresh and absorbing water. Mind blown.īut what is even more surprising is that within an hour of us starting the experiment we were able to notice some changes to the white flowers. All of the flowers absorbed the coloured water and highlighted how it travelled all the way to the tips of the petals to nourish it. This is the result of the flowers absorbing the coloured water after one week. ![]() It’s also a great idea to do this because children can return to their initial predictions and make comparisons to the actual end result. Some children may benefit from drawing their predictions. I wanted the end result to be a surprise to Possum and so I asked her what she expected to happen to the flowers over time. Place your jars in a safe location that will gives them some lovely natural sunlight. I highly recommend ensuring there are no leaves left on the stem as it can go mouldy in the water, which will reduce the time you can keep this activity. Quite simply, I cut the stem of the flowers so there was about 6 inches of stem remaining before placing one in each of the jars. Possum loved watching how the two colours, when combined, made a completely new colour. I didn’t have purple food colouring so I needed to create it using a combination of red and blue drops. Red, yellow, green, blue and purple were the colours I made the water. I added 1/2 cup of clean water and 10 drops of food colouring to each of the jars. To set up this activity I simply used a collection of small jars. Obviously some flowers may not absorb water as well as others. ![]() I used chrysanthemums, but you might like to use whatever white flowers you have available. ![]() White flowers (chrysanthemums, roses or daisies would work well).It’s amazing and creates a great ‘WOW’ factor for kids. To do this science activity you will need the following materials – The brightly coloured water will transform the white flowers within only a few minutes. It teaches them how a plant absorbs water up it’s stem and nourishes its petals or leaves. This activity is an amazing visual for kids. Recommended age : 3 years + (Active supervision is required on all my activities) It only required a few materials to set up this science experiment and inspired Possum (aged 3.5 years) to learn more about plants and how they absorb water. I loved doing it so much myself and watching the changes that seemed to happen within the hour! This is such a classic science activity that your children will absolutely love. It helps children learn about how plants absorb water through its stem to nourish the head of the flower. This will have your children observing a simple science experiment with colour changing flowers! It is easy to set up and is a great lesson, especially for preschoolers. ![]()
