Can Water Float on Water?
 * Before you take a look at this experiment ask yourself whether or not water can float on water. This question will be answered once you conduct this experiment that takes the temperature and salinity of water into consideration. The objective and the introduction provide you with background information on this concept as well as maps of the world that demonstrate the temperature and salinity of the oceans. A list of required materials is followed by detailed steps of the procedure. Variations of the experiment are presented as well.

Hot issues: Water Scarcity
 * Published on the Web by the Food and Agriculture Organization of the United Nations (FAO), this discussion of the link between water scarcity and poverty is from a collection of information resources intended to analyze the impact of water scarcity around the world. The material features a definition of water scarcity and a summary of conservation and sustainability issues related to the distribution and management of freshwater and ground water for human consumption, agriculture and industry. Illustrations include photographs, graphs, and a global water scarcity map to demonstrate the physical and economic distribution of resources.

Marine Litter: More than a Mess
 * Litter on beaches is very unattractive and hurts the environment. But, litter in our oceans is even worse. Every day, marine animals and birds die from plastic six-pack rings and plastic bags. Countries all over the world are facing this problem. "Some experts say that cleaning up the seas is likely to become one of the most pressing environmental issues of the next decade." Here you will learn where marine litter comes from, why marine litter is lethal, marine litter laws, and what can be done about the marine litter problem.

Water
 * When different elements come together they form a compound. Compounds can have two atoms or two hundred atoms. Compounds with the same number of atoms which are different shapes are called isomers. Some elements will only combine with certain other elements which will make their outer electron orbital full. The names of compounds can be very long but are very specific and predictable. There are usually two words describing the parts of the compound. Most compound names end in "ide."

Water Desalination: Fresh Water from the Sea
 * With water shortages becoming a sobering reality in our world, imagine if we could use the water in our oceans for drinking water! The process of desalination can achieve just that by removing the salt from ocean water to make it safe for drinking. Readers will find many interesting facts about water desalination on this site including how much salt is in ocean water, when desalination was first used, and how much it costs to desalinate water.
