Before adding anything to alter the soil pH, always make sure to test your soil to see how far it is from your goal pH. You can purchase a test at your local home/garden center or take a sample to your county extension office for professional testing. The pH of your garden soil is easy to determine with a commercial pH testing kit. These are usually sold at hardware stores or garden supply stores and are fairly inexpensive. To begin, you'll want to take a sample from the area you want to test. Dig five small holes (about six to eight inches deep). Select random locations within the plot this way, you'll get a sense of the "average" pH of your soil. Don't keep any of the dirt from creating the holes. Note that the instructions in this section are generalized you should use the instructions included with your specific pH testing kit. Next, use your shovel or spade to take a narrow "slice" from the side of each hole. This slice should be crescent-shaped and about 12 inch (1.3cm) thick. Try to make your sample about the same size for each hole. Add your samples to a single clean, dry bucket. Try to gather enough dirt in each sample that you have about a pint (0.94 liters) or more in total. For most methods of testing, this is plenty. Allow your soil to dry until you can no longer detect moisture. It's important to make sure your soil is completely dry before proceeding moisture can cause an inaccurate pH reading. Depending on the type of kit you have, the method will vary. For many of the most common test kits, you'll put a small amount of your soil in an included test tube, add a few drops of liquid solution, mix by shaking, and allow the mixture to settle for a few hours. Eventually, the color of the solution should change by comparing the color of the solution to a chart provided with the kit, you can determine the pH of your soil. Other types of kits exist as well, so be sure to use the instructions provided with your kit. For instance, some modern electronic testing kits determine a soil pH almost instantaneously via a metal probe. You can also collect a sample and take it into your county extension office for a free soil test.

Summary: Test the soil pH. Dig five small holes in the planting area. Take a sample from each hole. Mix the soils in the bucket and spread on newspaper to dry. Use your testing kit to determine the precise pH level of your soil.

The solute is the substance that you're mixing in to form your solution. If you're given the mass of the solute in your problem, write it down and be sure to label it with the correct units. If you need to find the mass of the solute, then weigh it on a lab scale and record the measurement. If the solute you're using is a liquid, then you can also calculate the mass using the density formula, where density D = m/V, where m is the mass of the liquid and V is the volume. To find the mass, multiply the density of the liquid by the volume. The total volume of the solution is the amount of solvent plus the amount of solute added to it. If you're finding the volume in a lab, mix the solution in a graduated cylinder or beaker and look at the measurement. Measure the volume from the curve at the top of the solution, or the meniscus, to get the most accurate reading. Record the volume of the solution. If you aren't measuring the volume yourself, you may need to convert the mass of the solute into volume using the density formula. For example, if you're finding the concentration of 3.45 grams of salt in 2 liters of water, you would find the volume of salt using the density formula. Look up the density of salt either in a textbook or online and solve the formula for m. In this case, the density of salt is 2.16 g/mL. The formula would read 2.16 g/mL = (3.45 g)/V. Multiply each side by V to get V(2.16 g/mL) = 3.45 g. Then divide the each side by 2.16 to find the volume, or V = (3.45 g)/(2.16 g/mL) = 1.60 mL. Add the volume of the solute to the volume of your solvent, ma. So in this example, 2 L + 1.6 mL = 2,000 mL + 1.6 mL = 2,001.6 mL. You can either leave the measurement in milliliters or convert it back to liters to get 2.002 L. Write out the equation C = m/V, where m is the mass of the solute and V is the total volume of the solution. Plug in the values you found for the mass and volume, and divide them to find the concentration of your solution. Don't forget to label to label your answer with the correct units. In our example for the concentration of 3.45 grams of salt in 2 liters of water, your equation would be C = (3.45 g)/(2.002 L) = 1.723 g/L. Certain problems may ask for your concentration in specific units. Be sure to convert the units before putting them in your final formula.

Summary: Find the mass of the solute mixed in with the solvent. Record the total volume of the solution. Divide the mass of the solute by the total volume of the solution.

Article 9 of your constitution should provide the rules on amendments to the constitution. This article should state how and by whom amendments can be proposed and what percentage of vote is required for the amendment to be adopted. A common example is two-thirds of the voting membership. This article may state, for example, "Amendments to the Constitution may be proposed by two-thirds (23) vote of the Student Council or a petition signed by fifty (50) currently enrolled students." Article 10 of your constitution should provide for how the constitution you are proposing shall be ratified. This article can say, for example: "This constitution shall be established by a vote of a (insert fraction) majority of the membership of the organization." A recommended fraction for ratification is a 3/4ths majority. You can write, in Article 11, for example: "Questions concerning the interpretation of this document shall be decided by the Board."

Summary: Write how the constitution can be amended. Write how the proposed constitution shall be ratified. Write how questions concerning the interpretation of the constitution shall be decided.

There are many different types of trends: fashion trends, slang trends, new dances or social media trends. Some are easier than others to pull off, and all take a great deal of effort to popularize. You'll want it to have a couple of qualities: mainly originality and simplicity. Creative, simple and accessible trends catch on because many people notice the trend and are able to participate. Make sure your idea is original. While many trends build on current styles and ideas, good trends represent something unique. You'll need to come up with an idea that is not only unusual, but makes people wish they had thought about it before. The trend needs to be something that truly interests you too, and not just something new for the sake of being new. Make sure it's original and authentic to who you are as a person. Keep your trend simple. The more complicated a trend is and the more steps people have to follow, the less they will be interested. Trends like slap bracelets, the Macarena and reaction videos are simple, easy to make, learn or buy, and none of them take a lot of work for normal people to participate in. Try to angle for the same simplicity with your trend. You'll want to make sure that your trend is relatable and interesting to those around you. It will only catch on if other people find it interesting, so make sure it makes sense for the setting you spend your time in, whether it's school, an office, or an internet forum.
Summary: Think about the type of trend you want to start. Think about the qualities of your trend. Tailor the trend to your environment.
