The Insulator – Thermal Insulator Challenge. Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer.

Hands-On Engineering Meets Real-World Science

Bring the principles of heat transfer, energy conservation, and design thinking to life in your classroom with The Insulator – Thermal Insulator Challenge—a creative, inquiry-based STEM project where students build and test their own insulating container using only recycled materials.

This low-prep, high-engagement activity challenges students to design a functional thermos that keeps water hot for as long as possible without using electricity, heating elements, or pre-warmed materials. With real-world constraints and clear assessment criteria, students apply physics concepts in a meaningful and memorable way.

✅ Perfect For:

• Grades 6–9 science and STEM classrooms
