Bored kids? Try a colorful science experiment!
Finding neat activities to hold kids interest can be a challenge at the best of times - this is a great little science experiment that has multiple levels of keeping them engaged!
Spend an hour or two outside picking the buds from wild violets - they’re the little purple flowers that grow in a lot of yards worldwide - if you’re in the northern hemisphere this is the best time of the year to find them! You’ll want enough flowers to fill whatever glass container you want to use. After you’ve got your violets, cover them in boiling water and let them steep for about fifteen minutes - if your kids are little and don’t have the “don’t touch” thing down yet please let it cool before proceeding! The longer the violets sit the darker the water will be anyway, which gives you a more intense reaction. Once you’re ready, stir the mixture and then strain the flowers out and you’ll be left with a really pretty dark blue liquid.
Make sure you’re in a well lit space and that the violet tea is in a clear glass container so you can see the reaction - I set up an old USB ring light to really show through in the video, but in person it’s easier to see so sitting it in front of a window or just in a brightly lit room will be fine! Now it’s time for the magic - add about a tablespoon of lemon juice (fresh or bottled, it doesn’t matter!) and the liquid will quickly change from deep blue to hot pink!
It’s such a cool reaction to see in general, and it’s also easy to adapt for learning at different ages. My son is a toddler so right now it’s more of an “oooh look at the colors change!” moment, but there’s so much more you can dive into with this. The color of violets is heavily dependent on the pH of their environment because of pigments called anthocyanins - they turn the hot pink color in the presence of acids, but they also turn a greenish color if you add a basic solution like baking soda or milk of magnesia. Try adding different liquids and seeing what changes colors - it’s a great way to do a simple pH experiment with supplies you already have!
After trying that amazing wild violet pH experiment, I realized how much potential there is to explore chemistry concepts right at home! It’s truly a fun, cheap, and easy way to introduce 'pretty science' to kids of all ages, turning them into little STEM enthusiasts. This experiment is a fantastic starting point, but the learning doesn't have to stop there! Adapting the Wild Violet pH Experiment for Different Ages: For toddlers and early preschoolers (addressing 'science for 2 year olds'): Focus primarily on the sensory experience and the 'wow' factor of the color change. Let them help strain the violet tea (once cooled!) and marvel at the transformation from blue to pink. Simple questions like, "What color is it now?" and "What happens when we add this?" can introduce basic cause-and-effect without getting bogged down in complex vocabulary. For elementary school children (addressing 'easy science experiments for kids', 'small experiment for kids'): This age group is ready to dive a bit deeper. Introduce the concepts of 'acids' and 'bases' in simple terms. They can make predictions about which household liquids (like vinegar, orange juice, or soap dissolved in water) will cause a color change and record their observations. This helps them practice hypothesis formation and data collection, fundamental scientific skills. For middle and high school students (addressing 'science experiments for high school', 'best science projects for class 6/8', 'science experiments for school'): The wild violet experiment becomes a gateway to a more thorough understanding of the pH scale and natural indicators. Discuss anthocyanins in detail – these are the natural pigments responsible for the color. Explain the pH scale (0-14), where acids are below 7, bases are above 7, and 7 is neutral. Students can test a wider range of substances, plot their results on a pH scale, and even research how natural indicators are used in real-world applications, such as testing soil acidity for gardening. This elevates it to a proper 'science experiment with explanation' level, fostering critical thinking and analytical skills. Beyond Violets: More Easy Home Science Fun: If you enjoyed the violet experiment, you'll be thrilled to know there are tons of other simple, engaging science projects that are just as fun and cheap. For instance, the classic baking soda and vinegar volcano is always a hit, demonstrating acid-base reactions with fizzing excitement. Or, create a mesmerizing DIY lava lamp using oil, water, food coloring, and an Alka-Seltzer tablet – it teaches about density and immiscible liquids, directly touching on the 'DIY lava lamp' query. Another favorite is making 'oobleck' (cornstarch and water), a non-Newtonian fluid that behaves like both a solid and a liquid, offering a fantastic sensory experience and a lesson in states of matter. These are wonderful ways to keep the STEM learning going! Deep Dive into 'Pretty Science': The Magic of Anthocyanins: The 'crystal violet reaction' query often pops up, and while our violet experiment doesn't use the synthetic crystal violet dye, it showcases a similar principle with natural anthocyanins. These incredible pigments are responsible for the vibrant red, purple, and blue colors in many fruits and flowers (think red cabbage, blueberries, grapes!). Their molecular structure changes depending on the acidity or alkalinity of their environment, causing them to absorb and reflect different wavelengths of light – hence the stunning color shifts. Understanding this helps explain why your violet tea turns pink with acidic lemon juice and green with a basic solution like baking soda. It's a fantastic real-world example of chemistry in action, making it ideal for 'science day activities in school' or a 'science project' where kids can explain the 'why' behind the 'what'! This entire process is about making 'pretty science' accessible and exciting, turning everyday observations into profound learning experiences for 'STEM kids'.
