SCIENCE PROJECT: TITLE OF YOUR PROJECT 1: Shaking For Suds: Which Type of Water is the hardest?

(Question) || How hard are different common water types comparely? ||
 * Statement of the Problem


 * List your keywords in the right hand column || Water Hardness, Water Softness, Hydrologist, Mineral ||

(Post your document in the next column) ||  ||
 * Review of Literature/Bibliography

controls: the amount of water,the amount of soap,and the same jars.
 * Hypothesis || We think that mineral water will be the hardest followed by tap, and distilled water. ||
 * Variables ||  ||
 * The independent variable, which will be changed and tested is || The different types of water ||
 * The dependent variable will measure the change by || The amount of soap drops ||
 * The constant variables for all of the tests are the same || The containers ||

Don’t you hate it when you put a ton of bubble bath in your tub and the bubbles still won’t come up? What about those rusty pipes? Here are some more problems hard water can produce...   “ Increased water heating costs due to scale buildup and mineral deposits, and more frequent replacement of hot water heating elements Soap scum on bathtubs, shower tiles, and basins Film left on the body resulting in dry skin and dull, limp hair Decreased bubbling and cleaning capabilities of soaps and detergents, resulting in dingy laundry and reduced life of clothing Increased buildup of scale on plumbing fixtures and cooking utensils such as a tea kettle, coffee maker, pasta pot, and dishes Clogged pipes or appliances resulting in reduced water flow and increased repairs” ( [] )

Not to insult hard water users; hard water has been shown to help human health. |||||| ** Water Hardness Scale **  ||
 * Grains Per Gallon ||  Milligrams Per Liter (mg/L)or Parts Per Million (ppm)  ||  Classification  ||
 * less than 1.0 || less than 17.1 || Soft ||
 * 1.0 - 3.5 || 17.1 - 60 || Slightly Hard ||
 * 3.5 - 7.0 || 60 - 120 || Moderately Hard ||
 * 7.0 - 10.5 || 120 - 180 || Hard ||
 * over 10.5 || over 180 || Very Hard ||

What is hard water? We’re not talking about hard, like rocks. Water is “hard” when a certain number of grains are in a gallon or milliliters in a liter (ppm). This table explains that...   ( [|http://www.fcwa.org/water/hardness.htm]    Do you have hard water? If you live in a state like Maine or the Carolinas you may have not even heard of hard water but if you live in Wyoming or Colorado hard water is something you deal with every day. This map shows th e areas that hard water is the hardest. [|(http://water.usgs.gov/owq/hardness-alkalinity.html])

How do you find how hard water is? Scientists have many complicated machines to do this, but you can find that using soap. Since hard water reduces soap suds, you can compare two types of water by how many drops of soap they need to get enough soap suds. The harder water would need more soap drops. This simplifies whether or not you have hard water. This is our experiment.


 * Procedure of Investigation ||  ||
 * Materials Used || 1 gallon of distilled water, 1 gallon of tap water, 1 gallon of mineral water (uncarbonated) ||
