A covalent bond yells at an ionic bond, "Didn't anyone teach you to share?" Four matching puzzles allow pupils to review covalent, ionic, and metallic bonding. They apply logic and problem solving to complete gridlocks including the...

Learning names and formulas can be a daunting task for young chemists, so support their study with interactive puzzles! First, users match each formula with its correct name. Then, individuals use them to complete three logic games.

When two liquids combine and a solid forms, the new substance is called a precipitate. Scholars test their knowledge of hydroxide precipitates and their properties. A series of four increasingly difficult puzzles challenge their logic...

The anode, the positive electrode, attracts negative charges, which is why we call negatively charged atoms anions. The interactive allows pupils to match six different anions to the associated properties when testing. Offering four...

[Free Registration/Login Required] Manipulate the electrons and protons to explore metallic bonding. Then answer a self-correcting concept question.

Examine what it is that gives metal its special characteristics and how metal behaves under the stress of heat and outside forces. An engaging interactive feature is offered to here to illustrate this concept.
