O Chemis-tree, O Chemis-tree!

By Lori Altenbaumer, 7th/8th Math & Science

This holiday season, our simple classroom Christmas tree was transformed into something extra special—a Chemis-tree! By decorating the tree with chemistry-themed ornaments created by our students, we were able to blend seasonal fun with meaningful science learning.

Our 7th graders kicked off the project by designing original ornaments inspired by the Periodic Table. Using element symbols, atomic numbers, families, and trends as references, students brainstormed creative ways to turn chemistry concepts into eye-catching decorations. From colorful representations of element groups to symbolic nods to atomic structure, their ornaments showcased both scientific thinking and artistic flair.

Meanwhile, our 8th graders took a deeper dive into chemistry by researching a specific assigned element. Each student explored key properties—such as atomic number, atomic mass, state of matter, uses, and unique characteristics—and then translated that research into a 3D paper ornament. The result was a collection of ornaments that didn’t just decorate the tree, but told the story of each element hanging from its branches.

Instead of a traditional star, our Chemis-tree was topped with an Erlenmeyer flask, perfectly capturing the spirit of experimentation, curiosity, and discovery that defines our science classroom.

Beyond the festive fun, this project was a great introduction to chemistry for both grade levels. It allowed students to build familiarity with elements, properties, and chemical thinking in a creative, low-stress way—setting the stage for the deeper chemistry work we’ll be exploring next semester.

Our Chemis-tree now stands as a cheerful reminder that science can be creative, collaborative, and fun—and that curiosity is always worth celebrating.
