Should you trust the water you drink every day? The hands-on activity has scholars test water from different sources for contaminants. Pupils perform chemical testing and make conclusions about pH, hardness, iron, chlorine, lead, and...

Ozone, made of three bonded oxygen atoms, is found 15-30 km above Earth, has a strong smell, is blue, and blocks sunlight from hitting the surface of Earth. The 22nd lesson in a series of 36 specifically focuses on the important elements...

Water filtration — that's pure genius! Groups test the ability of a water filter to purify water by running chlorine contaminated water through a filter and measuring the chlorine concentrations as they filter the water. They then graph...

Ever wonder how salt forms? Watch as a video instructor adds a solid sample of sodium to chlorine gas to form salt. The video then explains chemistry concepts associated with the reaction.

An introduction to the noble gases shows how full electron shells on an atom makes an element unreactive. Your class will then develop an understanding of how sodium and chlorine react ideally because of their electron arrangement....

Using chlorine as the model to demonstrate the structures and representations, this PowerPoint clearly labels and details the main atomic structures and reasons for bonding. The electrons in the outer shell are diagramed and then the...
