Hard Water How can water be hard? Well‚ it can‚ but maybe not in the sense that one would think. Hard water refers to water with dissolved calcium and magnesium ions in it. Rainwater is naturally soft‚ but when the water runs through the ground or over rocks causing erosion‚ calcium and magnesium ions can be easily picked up. Most people prefer hard water to soft water for drinking‚ because the ions are good for you‚ and because soft water leaves a “dry” taste in one’s mouth (1‚2). Big businesses

Deionized Water vs. Distilled Water Deionized and distilled waters are both processed forms of water. Deionized water is produced by filtering water to the point where it is free of ions. This ion-free water will strip ions from surrounding material‚ acting like a super-solvent. This is often used in semiconductor and other high-tech processing as a "soft" solvent and relatively cheap cleaning fluid. Distilled water is most often produced by vaporizing less pure source water (tap‚ salt or even

or Water? PURPOSE The purpose of this lesson is to investigate the heat capacity of water and land and to explain how the properties of water influence coastal climates. EXPERIMENTAL DESIGN In this experiment‚ you will heat the same volume of water and sand or soil in two different containers. They will compare the temperatures of the water and the sand or soil as each beaker is heated and as each beaker cools to answer the question: Which Absorbs and Loses Heat Faster––Land or Water?

It felt as though I’d been slammed between two steel plates and pushed

Poisoned Waters Film Review This article goes perfect with what we have been reviewing in class. It shows some of the main obstacles that environmentalists are facing and focuses on one section that is in dire straights. Back in the seventies the United States started up the EPA and it worked very effectively to clean up our environment because it had very strict regulations that developers had to adhere to. This process was cleaning up our ecosystem and things where getting back to a sustainable
