This lesson explores the various uses of elements in the periodic table. Students will be assigned an element to research. They will then present its uses and atomic information to the class.

Explore the concept of electronegativity and how it trends across the periodic table of elements. The author uses simple, humorous drawings to help with understanding.

Young scholars observe and perform experiments with sodium, potassium, calcium, magnesium, sulfur ,and phosphorus. The discover trends down groups, across periods, and having to do with the pH of metal oxides vs. nonmetal oxides.
