Design and Development of a 3D Cylindrical Periodic Table Model Using Locally Available Materials: The Cylindrical-Spiral Cardboard Helix (CSCH)

This white paper documents the design, historical basis, and construction of a 3D Cylindrical-Spiral Periodic Table Model (CSCH), built to address a common learning gap in Senior School chemistry: students memorising element positions without understanding periodic trends or the...
