Discovering the Periodic Table

Wouldn't it be great if children could actively discover why the periodic table looks like it does? They can find out lots about the layout of this ionic chart with the "Discovering the Periodic Table" learning material. It is newly updated with the names and symbols of all 118 chemical elements. Each element has a card that shows its name, symbol, and atomic number on the front. On the back, there is a listing of its physical properties, chemical properties, and its uses or other information. The chemical properties are given in a simplified form, expressed as how many atoms of chlorine or hydrogen react with one atom of the element.  First, children lay the cards out and reproduce the periodic table. Then they turn over the cards, selected groups at time and discover what properties those elements have in common. In the process, they will become more familiar with the periodic table. They will likely find intriguing elements that they want to research further. Secondary students may
