Problem: Write an article based on this summary: Use as many visual items as possible. Label all your graphs, charts and photos. Include the proper terms and jargon. Remember that less is more. Buy the proper display board.

Answer: Words are great, but pictures say much more. Include as many pictures, graphs, tables, charts, diagrams, etc., as possible. Keep your backgrounds (i.e., whatever is behind your graphics and text) simple and subtle. Reading the text that is on top of a colourful or complex background can be difficult and distracting. Try to print as many of your graphics in colour as possible, especially graphs and charts where the colour distinguishes between different items or variables. If you don't have access to a colour printer, you can use markers or crayons to add color to things like graphs and charts. Each visual item (graph, chart, table, diagram, picture, etc.) should have its own number (or letter), plus a descriptive caption. When the main text refers to a specific visual item, that number or letter should be used. The caption should accurately and quickly describe what is contained in the visual item, and can be printed in slightly smaller font (less than 16 pt). Your main text and captions should include the technical or scientific names, terms and jargon for the discipline your project is based on. If necessary, you can also include a glossary of terms on your display board or in your project report. Using the proper terms is especially important if your project is being displayed in a science fair or event that is being judged by professionals. If your project is really complex, you can also include a 'layman's summary' as part of your display which sums up your project in language anyone can understand. This is particularly useful if your display board is also being viewed by fellow students, parents, or non-professionals. It can be tempting to get really creative and eccentric when creating a project display board, but try to avoid the temptation! A good project display board is one that is uncluttered, has easy-to-read and clear material, contains graphics that effectively explain your project, and colours that don't overwhelm the viewer. Search the web for example display boards to get an idea of what works well, and what doesn't. Ask your teacher for advice on what to do and not to do, and for examples of project boards that previously received awesome grades. Display boards come in a standard size of 36" tall and 48" wide. You can buy or make larger (or smaller) boards, but make sure the size is not only appropriate for your display but also allowed by the event (if such rules exist). These display boards have three panels - the middle panel which is half the width of the whole board, and the two outside panels that are a quarter of the width each. The two outside panels can fold over the middle panel to close the board for transport. And the outside panels can be used to stand the whole display board upright on a table. You can find display boards at online retailers like Amazon.com or at your local school supply store. Bigger is not always better. Boards that are really tall or really wide may be difficult to read and/or contain too much information.

Problem: Write an article based on this summary: Ask companies to take them back. Find a drop-off center. Send them to a recycling center.

Answer: If you receive a package with packing peanuts, inquire as to whether the company will take them back. They are likely to agree as they will be able to reuse them for another customer, saving the company money. Though you likely cannot recycle packing peanuts in your bins at home or at the local drop-off center, there are places you can drop them off for recycle. The Alliance of Foam Packaging Recyclers has a list of places to drop-off packing peanuts by state (U.S. only) on the AFPR website The Plastic Loose Fill Council also lists drop-off locations by state (U.S. only). Though you may have to pay for shipping, many companies, such as the EPS Industrial Alliance, will take your packing peanuts for free.

Problem: Write an article based on this summary: Learn to test the quality of gold. Follow market prices. Obtain a scale. Buy gold from customers. Purchase gold at trade shows. Purchase gold in large volumes.

Answer: Test gold with a magnet. Gold does not have magnetic properties. Test gold with a fine steel file. Gold is easy to file, but the file will bounce off of other metals. Purchase acids for testing. Follow the instructions on the package to test the gold for genuineness, testing in an inconspicuous spot to prevent visible damage. You can find the daily market prices of gold on many brokerage websites. You will need to purchase a jeweler's scale that weighs gold according to pennyweight (1/12 of a troy ounce) rather than simply weighing gold in grams. Many customers are happy to sell their gold jewelry and coins to a respectable dealer. Many dealers at a trade show will give a price break to someone who is just getting started in the business. Large volume purchases tend to have a lower price per ounce.

Problem: Write an article based on this summary: Know the basic formula for calculating molarity. Examine the problem. Find the molar mass of the solute. Convert the grams into moles. Divide the number of moles by the number of liters. Write your answer.

Answer:
Molarity expresses the relationship between the number of moles of a solute per liters of solution, or the volume of that solution. In formula form, molarity is expressed as: molarity = moles of solute / liters of solution Example problem: What is the molarity of a solution made by dissolving 3.4 g of KMnO4 in 5.2 liters of water? Finding molarity demands that you have the number of moles and the number of liters. If you are not provided with the number of moles but you do have the volume and mass of the solution, you will need to use these two figures to calculate the number of moles before continuing on. Example problem: Mass = 3.4 g KMnO4 Volume = 5.2 L To calculate the number of moles from the mass or grams of solute used, you must first determine the molar mass of the solute. This can be done by adding together the separate molar masses of each element found in the solution. Find the molar mass of each element using the periodic table of elements. Make sure that you count the atoms for each element and calculate the molar mass of each of the atoms. Example problem: Molar mass of K = 39.1 g Molar mass of Mn = 54.9 g Molar mass of O = 16.0 g (The solute contains 4 O atoms, so count the 16g 4 times.) Total molar mass = K + Mn + O + O + O + O = 39.1 + 54.9 + 16 + 16 + 16 + 16 = 158.0 g Now that you have the molar mass of the solute, you need to multiply the number of grams of solute in the solution by a conversion factor of 1 mole over the formula weight (molar mass) of the solute. This will give you the number of moles of the solute for this equation. Example problem: grams of solute * (1/molar mass of solute) = 3.4 g * (1 mol / 158 g) = 0.0215 mol The grams units of the solute and solute mass cancel each other out so you are left with mol units. Now that you have the number of moles, you can divide this value by the number of liters of solution in order to find the molarity. Example problem: molarity = moles of solute / liters of solution = 0.0215 mol / 5.2 L = 0.004134615 You should round off the number of digits after the decimal point to the place requested by your instructor. Usually, this will be two or three places after the decimal point. Additionally, when you write out the answer, abbreviate "molarity" with "M" and state the solute involved. Example problem: 0.004 M KMnO4
