What common chemical includes safety warnings for being harmful if swallowed or inhaled, causes serious eye damage, and needs to be cleaned up immediately if spilled on the floor? Surprisingly, the dangerous chemical turns out to be...

Did you know many insects use cohesion or surface tension to walk on water? Using a presentation, scholars learn the more important properties of water. It extends into the concepts of solutions, suspensions, pH, and more.

Water is crucial to survival. Scholars gain an appreciation for water by reading about it, learning about its atomic properties, and investigating its properties through six stations in a lab activity.

The liquids did not mix — so what do density columns have to do with it? The seventh part in a series of nine provides the theoretical explanation of why density columns do not mix. The lesson covers the topics related to...

If you are not part of the solution, then you are part of the precipitate. The presentation covers solutions, suspensions, solubility, dissociation, and acid/base reactions. This is the 19th lesson in a series of 26.

Some like it hot! Scholars observe both exothermic and endothermic reactions as part of the carbon dioxide oxygen cycle. First, scientists demonstrate (or watch) a chemical reaction to create pure oxygen using fire for...
