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...

This is an online exercise in which chemistry learners answer a series of multiple choice questions about bonding. Topics addressed include ionic and covalent bonds, electronegativity, ions, valence electrons, resonance structure, and...

In this covalent and ionic substances worksheet, students use the internet to find information about the characteristics of covalent and ionic substance and explain what causes the differences in these types of substances.

Young chemists love it when colorful solid products appear in a reaction vessel! Scholars discover the products that form during halide ion tests through a hands-on activity. Users go online and apply chemistry knowledge and reasoning...

Don't take for granted the technology behind power packs. Build an understanding of the chemical mechanics of a battery pack that charges your phone. The simulation allows young scientists to manipulate the type of elements in a pack and...

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...
