__General Guidelines to Follow When Making Flashcards__
 * RETURN TO HOME PAGE**
 * 1) Use paper that is thick enough so your answers cannot be seen through it.
 * 2) Put one or two words on one side and a simple concept on the other side. Do not make your cards too complicated.
 * 3) Write with bold dark marker.
 * 4) The act of creating your cards is a great study tool in itself. Therefore, do not photocopy your friend's cards or do not have someone make them for you.
 * 5) Quiz yourself frequently with them.


 * There will be a quiz on this Flashcard Workshop on Friday, April 15, 2011. **
 * All boldface terms are good candidates for flashcards. These are some pretty complicated terms. You should have a minimum of 2 cards per boldface term. **


 * Turbidity: **// test of cloudiness. Units used to test it: JTU, 0JTU=perfectly clear. 200JTU=very cloudy. Turbidity can be caused by particles floating in the water, micro organisms, pollution, and tannin from decaying plants. //

** pH: **// Test of reactivity using the descriptors: acidity/alkalinity. p stands for potential, H stands for hydrogen. Measured on a scale of 0-14. 0=very acid, 7= neutral, 14=very alkaline // // ....................Neutral........................... // //0 1 2 3 4 5 6 7 8 9 10 11 12 13 14//   //Acid ...............* ...................Alkaline// // .5 ppm is low oxygen content and 4.0 is high oxygen content. //
 * Dissolved Oxygen: **// The amount of oxygen gas dissolved into water. It is important for animals that require it. Churning water makes more oxygen mix with it. Measured in ppm (part per million) //


 * Nitrates: **// Nitric acid salt (NO3) organic compounds made by living animals excreted as waste. Good fertilizer for photo- synthesizers. Measured in ppm (part per million) //


 * Temperature: **// measurement of heat energy in the solution. Water creatures need a specific range of temperature to live. Water must be warm enough to be a liquid. Measure with Celsius. 0º C is freezing water, 37º C is body temperature, 100º C is boiling. //

// Less than 1ppm is healthy. Over 4ppm becomes excessive. //
 * Phosphorus: **// Element found in phosphates. Phosphates are found in decomposing plants and animals. They are important nutrients for photosynthesizers. They are found in laundry detergents and other soaps. Too many phosphates can become toxic to animals and cause excessive growth of photosynthesizers. Measured in ppm. //
