Cottonwood middle school students working on activity related to minerals in cellphones — *Cottonwood middle school students working on an activity.*

At the Rice Museum, learning comes alive when students can connect the natural world to the technology they use every day. Recently, we welcomed middle school students from Cottonwood School for a hands-on educational experience made possible through a Smithsonian grant tied to the exhibition Cellphone: Unseen Connections.

During their visit, students explored the surprising and essential role minerals play in the devices they carry in their pockets. Through guided discussions and interactive activities, they discovered that cellphones rely on a wide range of minerals—from copper and gold to rarer elements like tantalum and lithium—sourced from locations across the globe. This global perspective helped students understand not only the science behind their devices, but also the environmental and human stories connected to mineral extraction.

One of the highlights of the day was the opportunity to dissect old cellphones. Equipped with tools and curiosity, students carefully took apart devices to identify the components inside and connect them to the minerals they had learned about earlier. This hands-on activity sparked excitement and deeper understanding, turning abstract concepts into tangible discoveries.

To wrap up their experience, students worked in groups to create their own displays showcasing what they had learned. These mini-exhibits combined creativity with critical thinking, as students illustrated the journey of minerals from the earth to their everyday technology. The results were thoughtful, informative, and a testament to how engaging, experiential learning can inspire young minds.

We are grateful to the Smithsonian for supporting this program and to the students and educators from Cottonwood School for bringing such enthusiasm and curiosity to the museum. Programs like these highlight the powerful connections between geology, technology, and our daily lives—and we look forward to continuing to share these stories with our community.
