"Lakes and seas in inland desert areas like the Dead Sea and the Great Salt Lake are famous for being so salty that hardly anything can live in the water. You can tell they are salty because it is very easy to float in them , and very difficult to swim. But just how salty are they? With this...

Just as air can have different densities, water can have different densities as well. As the salinity of water increases, the density increases as well. Fresh eggs will float in saltwater, but will sink in freshwater. This will show that as the salinity increases the density also increases.

The ocean is the key element in Earth's hydrologic cycle (water cycle). Students will construct a simple model of the hydrologic cycle to help them visualize and understand the movement of liquid water and heat. The hydrologic cycle is the continual movement of water from one place to another and...

This video from the American Chemistry Council highlights some of the ways chemistry is involved in keeping our water supply flowing and our drinking water safe. Did you know that aluminum and chloride salts remove impurities to keep water clean? Or that phosphate-based chemistries and epoxy resins...

The students will set up three demonstrations to observe the properties of water. They will explore the boiling point of water, the freezing point of water, and the ability of water to store heat. These activities can be done individually or as a set. About 71% of the Earth's surface is covered with...

What is sea ice? It is simply frozen ocean water. Why is sea ice important? While it occurs mainly in polar regions, sea ice influences our global climate. Changing amounts of sea ice can affect ocean circulations, weather patterns, and temperatures around the world. Sea ice insulates the relatively...
