Discovering the Periodic Table Kit
Product Code : EL-PT-11151
Last updated: 6 October 2026
Quick answer: A grades 9 to 12 inquiry kit for 32 students working in pairs, investigating periodic trends in atomic mass, electron configuration and oxygen bonding ratio, then graphing atomic radius, ionisation energy and electronegativity to visualise the trends.
The graphing step is what separates this kit from a descriptive treatment of the table. Students plot periodic properties, atomic radius, ionisation energy and electronegativity, so a trend stops being a sentence to remember and becomes a curve with a shape and a reason. Ionisation energy in particular only makes sense graphically, because the drops between periods are the evidence for shell structure.
The sequence runs from guided inquiry to design. Students first investigate periodic trends such as atomic mass, electron configuration and oxygen bonding ratio through guided inquiry of the periodic table, then use those trends and the properties of elements to design their own periodic arrangement. The listing also notes they practise the predictive nature of the table, which is the property that made it a scientific achievement rather than a filing system.
Including oxygen bonding ratio is a good choice: it is directly observable from compound formulae and varies periodically, so it gives students a trend they can derive from data they already have.
Materials are sufficient for 32 students working in pairs, which is 16 groups. The listing publishes the trend electronegativity as electro magnetivity, which appears to be a transcription error on the source page; the correct term is used above. The component list and the time required are not stated.
Note on the published text: the original listing names one of the graphed properties as electro magnetivity, which appears to be a transcription error for electronegativity. The correct term is used above. Confirm with the supplier that electronegativity is the property intended.
