10 Incredible October STEM Activities & Projects for Kids

Are you looking for educational and super fun October STEM activities to include in your lesson plans this month? Then look no further, you have come to the right place.

I’ve always adored October, considering it the most beautiful time of the year. Growing up in South Africa, October was when streets were blanketed with the vibrant purple blooms of Jacaranda trees. This dash of color symbolized the beginning of summer, bringing with it a warm, sun-kissed aroma.

Now, living in the USA, I still absolutely love October. The beauty here is different but just as mesmerizing. Trees burst in shades of red, orange, and yellow, getting outdoor fanatics and photographers all excited. The crisp air carries a hint of pumpkin spice, and there’s an unmistakable buzz of Halloween around. Who doesn’t love Halloween? Activities like apple picking and hayrides become the norm. For sports enthusiasts, the excitement of baseball’s World Series and the NFL season are irresistible. Columbus Day also encourages discussions about the nation’s history.

Moreover, October is dedicated to breast cancer awareness. The universal pink ribbons stand as a powerful testament to unity and hope. All these elements combined make October special not just for me, but for people all around.

8. Apple Browning STEM Experiment

The apple browning STEM experiment is a fantastic October activity to introduce learners to this real-world scientific event. I’m sure you (as I have never given it real thought up until now) and probably your child has wondered why apples turn brown and if all of them go brown together.

This simple experiment that is so easy to set up will shed light on these questions. Through observation, your little scientist will recognize the effects of ascorbic acid, commonly found in lemon juice. This is due to its low pH level that interacts with oxygen before the fruit’s polyphenol oxidase enzyme does that in turn delays the browning process. This hands-on exploration provides an excellent opportunity to discuss the pH scale and delve into brainstorming other substances that might similarly prevent apple browning. Incorporate this experiment in your October lesson plans to engage curious minds and stimulate discussions around everyday science!

This simple but captivating experiment allows children to predict and observe which objects float and which ones sink when placed in water. Not only does it spark their natural curiosity, but it also lays foundational concepts about density and the properties of different materials. Beyond the science, it fosters critical thinking, problem-solving, and observational skills. By introducing this engaging hands-on activity, you’re not just filling a playful afternoon for your child but nurturing your child’s scientific temperament. Explore the wonders of buoyancy this month and watch young learners grow with understanding and enthusiasm.

10. Pumpkin Clock STEM Activity

As it is the month of October and pumpkins are easily available why not use it to do another fun and exciting STEM activity? It is definitely worth creating a pumpkin clock with your child. Not only does it put those pumpkins to inventive use, but it’s also an electrifying lesson in green science. When you make a pumpkin clock, you’re essentially turning your pumpkin into a battery.

The magic (science) lies in tiny particles within the pumpkin, which help transform the chemical energy from metal strips into electrical energy. As a result, an electrical current flow between the strips, and the pumpkin facilitates this flow. This same current courses through wires, powering up the clock. So, in the spirit of October, let your children delve into this hands-on project. They won’t just be carving memories, but also lighting up their minds with the wonders of science!
