Unleash the Twin Tracks phenomenon— where curiosity and physics collide!
The Twin Tracks NGSS Power Pack ignites curiosity and brings energy and motion to life, transforming your classroom into an inquiry-driven learning experience. Entirely NGSS aligned, this demonstration tool allows students to explore the science of motion, energy transfer, and cause-and-effect relationships in a way that feels like both science and magic.
With two parallel ramps side by side, students can test predictions, compare outcomes, and investigate variables by altering surface materials, volume and mass of balls, and more. What looks like a simple race quickly turns into an engaging mystery—sparking rich discussions and deeper understanding.
Perfect for middle school and upper elementary classrooms, the Twin Tracks is more than just a demonstration—it’s a gateway to critical thinking and scientific inquiry. Students won’t just watch; they’ll hypothesize, test, and explain, all while experiencing firsthand the thrill of science in action.
