What's smaller than a kiwi seed? Atoms! Basic atomic structure is detailed for beginning chemists in a light-hearted animation. Protons and neutrons are explained as part of the nucleus, and so are electrons that encircle the nucleus....

What makes up the air we breathe? Young scientists explore the atoms and molecules in the air. An interactive lesson allows individuals to watch the movement of the particles in the air and change the makeup from a mixture to a...

Max Born and Fritz Haber developed the Born-Haber cycle in 1916, which is used for measuring enthalpy that otherwise couldn't be measured. Young scientists solve four matching puzzles using their knowledge of the stages, standard...

Ready to introduce the realities of molecular geometry to chemistry pupils? Use a logic-based interactive! Perfect as individual practice, the puzzles explore the bond angles and repulsions present in three common molecular shapes.

In this bonding worksheet, students take an interactive quiz with 15 multiple choice questions about the VSEPR Theory, bonding, the geometry of molecules, Lewis structures, resonance structures and enthalpy changes.

For this balancing equations worksheet, students use an on line source to answer questions about balanced equations and they write balanced equations for various types of reactions. They balance equations using an on line game that...

In this balancing equations worksheet, students use an on line site to practice balancing equations at the beginner level, the intermediate level and the advanced level. They balance four equations for the combustion of different compounds.

Matter is all around us, so it's a good idea to know what it is, and why it matters. Learn about matter, its categories, and its subcategories with this interactive lesson.
