Problem: Article: Since plasma TVs use more power and generate more heat than LCD TVs, it is best to turn the screen off before cleaning. Let the screen remain off for 15-20 minutes. This will allow ample time for the unit to cool before you clean the screen.  Failure to do this may cause your cleaning solution to evaporate before it has had enough time to remove any dust, dirt, or contaminants on your screen. You could use a microfiber cleaning cloth or a soft, clean cotton rag. Rub it gently in a circular motion across the TV screen to remove all signs of dust. This should be enough to remove most dirt and dust from your TV screen.  Avoid rubbing the screen with wood-based products (e.g., paper towels, toilet paper, tissues) because they can scratch the screen. If stubborn dirty spots persist after wiping the screen dry, you can dampen your cleaning cloth. Spray 2-3 squirts of the cleaning solution on the soft cloth. Do not spray the cleaning product directly onto the screen, or it may saturate the surface and damage the screen. Don’t use a stronger chemical cleaner (e.g., ammonia or benzene), as these substances will cloud and dim the displayed image. You can find isopropyl-alcohol based screen cleaners at most PC-supply or electronics stores. Try to find a cleaner designed to clean television or computer screens. Once your cloth is dampened, use it to wipe away any hard-to-clean fingerprints or smudges on the surface of your plasma screen. If the moistened cloth is not cleaning sufficiently, you can spray additional small amounts of cleaner on the cloth. However, don’t saturate the screen with liquid cleaner or you may damage the plasma.  At no time do you want the cloth wet enough that it causes the solution to drip or run down the screen! After wiping the screen clean with a damp cloth, run a dry cloth over it to soak up any residual moisture. This will prevent your plasma screen from being damaged by the liquid. Once the screen is dry, you can plug the set back in and resume watching TV.
Summary: Turn off the plasma display and let it cool before cleaning it. Wipe the screen with a soft, lint-free cloth to remove fingerprints and smudges. Spray an alcohol-based screen cleaner onto a clean cloth. Swab the screen with the dampened cloth to remove stubborn dust. Dry the screen with a separate clean, dry cloth.

INPUT ARTICLE: Article: Have the child bend over at the waist. Place your hand under her chest for support.  To perform this maneuver properly on a child, you'll likely need to kneel on the floor.  Don't try to pull the object out of the child's mouth if the child is conscious. Try to get it out with the Heimlich maneuver instead.  You can also place a child across your lap face down, if that is more feasible. Use the heel of your hand. Whack the child on the back directly between the shoulder blades five times.  These blows should be fairly hard. They shouldn't be hard enough to knock the child over with your support, but they do need to be relatively sharp.  The American Heart Association doesn't teach back blows when performing the Heimlich; the Heimlich alone (abdominal thrusts) can be effective without them.  Look to see if the object has dislodged. You may see the object fly out, or you may notice the child has started breathing again. Put your arms around the child. Use one hand to make a fist and place it directly above the child's navel. Try to get below the breastbone. Cover your fist with the other hand. Pull your fists upward into the child's abdomen. Make this thrust quickly. Repeat four times or until you notice the object choking the child dislodges. If no one is around and you've tried the Heimlich once, be sure to call 911. You want help to be on the way. If you asked someone else to call 911, make sure the person has done it. If it didn't work, continue moving back and forth between back blows and abdominal thrusts. Keep going until you see the object come out, the child begins to breathe normally again, or the child becomes unconscious.

SUMMARY: Bend the child over. Give five back blows. Place your fists. Pull upward. Call 911. Check to see if it worked.

In one sentence, describe what the following article is about: In scientific terminology, a fact is an observation that has been repeatedly observed and is accepted as practically functional and “correct.” While facts can be scientifically refuted or may not be consistent across time and place, they are held as true until they have been proven wrong. As you explain this concept, focus especially on separating fact from law, since both describe natural phenomena, albeit in different ways.  When explaining a scientific fact, start with a point of general observation. For example, begin your explanation by saying something like, “it is always bright outside at noon.” This is a fact in that it describes a state of nature—however, this statement may not be true in Antarctica or Greenland, where darkness lasts throughout the day in certain seasons. Explain how this will lead to a revision of the scientific fact: “within certain degrees of latitude, it is always bright outside at noon.” Facts are often the initial building blocks of scientific inquiry; they can generate curiosity and the hypotheses that come from inquiry and experimentation.  Facts are less formal than laws, and are not seen as an “official” definition of a phenomenon that occurs or of the reason that something happens. Facts are more localized and generalize less than laws. Explain that, if the Law of Evolution describes the way that species throughout the world evolve over time, a scientific fact related to evolution (and natural selection) could be: “giraffes with long necks can reach more leaves than giraffes with short necks.” Many students and adults hold to misunderstandings of scientific vocabulary and misunderstand the relationship of theories, laws, and facts. For example, scientific theories do not develop into scientific laws. To explain the difference, focus on this distinction: laws describe phenomena, theories explain phenomena, and facts describe observations.
Summary:
Define a scientific fact. Provide examples of scientific facts. Clarify the distinction between scientific laws and facts. Clear up any common misconceptions.
