Atomic Artistry: A Hands-On Journey into Electron Shells

This week, my Sec 2 student and I embarked on a wonderfully tactile adventure into the world of atomic structure as part of our Sec 3 Chemistry Introduction. Inspired by the Bohr model of the atom, we recreated the electron configurations of various elements using paper plates, coloured balls, and a whole lot of laughter.

Each plate became a canvas for scientific storytelling. At the centre, we wrote the chemical symbol of an element—Li, Be, B, Na, Mg, Al—and around it, we carefully placed concentric circles to represent electron shells. Then came the most delightful part: crafting tiny balls to represent electrons. We rolled, shaped, and counted them out, placing each one precisely in its shell according to the element’s atomic number. It was a beautiful blend of art and science, and a surprisingly meditative process.

Through this hands-on activity, my student discovered how atoms arrange their electrons in shells—starting with two in the first shell, then filling the second and third as needed. We talked about how atoms are electrically neutral, with equal numbers of protons and electrons, and how the arrangement of electrons affects an element’s chemical properties. Concepts like valence electrons, reactivity, and periodic trends came alive in a way that textbooks alone could never achieve.

What struck me most was how engaged my student became—not just with the science, but with the process. He asked thoughtful questions, made connections between elements, and even began to predict electron arrangements before we built them. The learning was deep, joyful, and sticky.

We also had a few giggles along the way—especially when our tiny electron balls rolled off the table or when we debated the best colour for magnesium’s electrons. It reminded me that science doesn’t have to be sterile or intimidating. It can be playful, creative, and deeply relational.

This activity wasn’t just about atoms—it was about discovery, connection, and the joy of learning together. I’m so proud of my student for diving in with curiosity and care. And I’m reminded, once again, that when we teach with our hands and hearts, the learning becomes unforgettable.
