Problem: Article: List step by step exactly what you will do to test your hypothesis. This step is not only important for making sure you’re correctly testing your hypothesis, but will also allow yourself and others to repeat your experiment.  For example, you should list precisely how much soil you put in each pot, how much water you give each plant and how often, and how much sunlight each plant receives (measured in watts per square meter). Reproducibility is one of the key underpinnings of the scientific method, so it’s important that you lay out exactly how your experiment is conducted to ensure that others can copy it and try to get the same results. Your experiment should test the effect of one thing (your independent variable) on another thing (your dependent variable). Identify what your independent and dependent variables and determine how you’ll measure them in your experiment. For example, in the potted plant experiment, the independent variable would be the amount of sunlight each plant is exposed to. Your dependent variable would be the height of each plant. Your experiment needs to either confirm or fail to confirm your hypothesis, so it needs to be carried out in such a way that the cause of the phenomenon can be isolated and identified. In other words, it should be “controlled.”  For example, you can design an experiment in which you place 3 different potted plants (of the same species) in 3 different locations: 1 on the windowsill, 1 in the same room but in an area with less direct sunlight, and 1 in a darkened closet. You would then record how tall each plant grows at the end of each week for a 6-week period. Be sure you're only testing a single phenomenon at a time. All other variables should be constant across your samples. For example, all 3 of your plants should be in the same size pots with the same type and amount of soil. They should also get the same amount of water at the same time each day. For some complex questions, there may be hundreds or thousands of potential causes and it can be difficult or impossible to isolate them in any single experiment. Other people must be able to set up a test in the same way that you did and get the same result. Make sure you keep very thorough records that document the experiment, the procedure you follow, and the data you collect. It’s very important that you make it possible for other scientists to precisely copy everything you did when they repeat your experiment. This allows them to rule out that your results came from any discrepancies or mistakes. Once you’ve designed your experiment, you’ll need to carry it out. Make sure your results are gathered in quantified metrics that allow you to analyze them and allow others to try to repeat your experiment objectively.  In the potted plant example, place each plant in the areas with differing amounts of sunlight that you selected. If the plants have already grown above the soil line, record their initial height. Water each plant with the exact same amount of water on a daily basis. At the end of each 7-day period, record each plant’s height. You should run your experiment several times to make sure that your own results are consistent and to weed out any anomalies. There’s no set number of times you need to repeat an experiment, but you should aim to repeat it at least twice.
Summary: List the procedure for testing your hypothesis. Identify your independent and dependent variables. Design your experiment so that it isolates the cause of the phenomenon. Maintain impeccable records. Run your experiment and gather quantified results.

In one sentence, describe what the following article is about: Typically, the back of the refrigerator is the coldest part, which will help preserve the flavor and texture of the caviar. Do not open the tin until you are ready to eat it, as this will decrease its shelf life. It is a good idea to only purchase the amount you expect to eat in a single sitting. However, if you do have leftover caviar, return it to the original tin, place a piece of plastic wrap over the top, and close the tin securely. Then, put the tin back into the refrigerator for 1-3 days to keep the taste fresh. To preserve the flavor, only use coated dishes and spoons when you're serving caviar. Avoid serving the caviar with a metal spoon or dish, as the delicacy will absorb the metal flavors. If you do not have one of these special spoons, grab a simple plastic or wooden spoon instead. You can purchase caviar spoons at your local department store in the kitchenware section or online with major retailers. Caviar is a delicate dish that should be kept chilled. This will help preserve the flavors and quality of the product. You could also rest the caviar bowl on an ice pack if you don't have any crushed ice on hand. To get the most from the experience, bring the caviar to your nose and inhale the aroma, then taste a small amount. Try not to chew the caviar or you might miss some of the more subtle flavors, as well as the unique texture. Instead, use your tongue to roll the eggs around in your mouth. Caviar is very rich, and it’s meant to be tasted or served in small amounts. If you are eating it plain, aim for 1/2 tsp (2.67 g) of caviar per tasting. If you are including it in a meal or as an appetizer, use approximately 1-3 tsp (5.33-16 g) of caviar. Since caviar is a traditional Russian delicacy, it is often paired with vodka. The vodka complements the flavors of the caviar and cleanses your palate between tastings. If you’d prefer something a little lighter, though, caviar and champagne go together very nicely.
Summary:
Store your tin of caviar in the back of the refrigerator. Use a bone, crystal, or mother of pearl spoon to handle the caviar. Keep the caviar chilled on crushed ice while you have it sitting out. Eat a small spoonful of plain caviar to experience the subtle flavor. Sip on a glass of chilled vodka or champagne to cleanse your palate.
