This activity is both easy to prepare and highly engaging for students. It serves as an effective way to introduce the concept of sound tones and is suitable for use during science lessons, extracurricular clubs, or independent project work. One of the strengths of this activity is its accessibility—the required materials are simple and can be readily found at home or in the classroom, making it an inclusive and adaptable option for diverse learning environments.

One of my professors during my master’s program once told us that every teacher should have a box filled with miscellaneous items—popsicle sticks, old tires, scrap paper, marbles, broken toys—anything that might seem useless at first glance. When approached with creativity and curiosity, these everyday objects can be transformed into meaningful teaching tools.

At the school where I worked, we didn’t have a budget for laboratory supplies. This challenge pushed me to think outside the box and look for alternative experiments using only the materials we had on hand. In doing so, I discovered a wide range of unconventional lab activities and creative classroom experiments, many of which I later shared with chemistry teachers across the country.

That experience taught me a powerful lesson: sometimes, limitations aren’t obstacles—they’re opportunities for innovation.
