Speak to the clerk at your local auto parts store to get help choosing the right spark plug for your engine.  Spark plugs burn at varying degrees of intensity and it’s important to choose one designed for use in your vehicle.  You can also find out what spark plug is right for your vehicle by referring to the service manual for its specific year, make and model. Make sure to disconnect the battery prior to moving on. Before installing the new spark plug, use compressed air from a can or air compressor to clean out any dirt or debris that may be in the hole you are inserting the plug into.  This will prevent any of it from falling into the engine and damaging it.  Be extremely careful not to drop any debris or small tools into the hole for the spark plug. A shop vacuum may be a better choice if debris has already fallen into the hole. The gap on the spark plug’s sparking surface dictates the length of the spark that is used to ignite the air and fuel within the engine.  Use a spark plug gapping tool to create the correct gap in the spark plugs before installing them.  Most spark plug gapping tools are shaped in a circle.  Insert the edge of the circle into the gap between the plug and its sparking surface, then turn it until it reaches the gap for your vehicle. Find the appropriate gap size for your engine by referring to your vehicle’s service manual. Insert the spark plug into the rubber boot in the spark plug socket, then attach the socket to a socket extension that’s at least a few inches long.  This will allow you to screw the plug in like you might screw in a screw with a screw driver.  Make sure the extension is long enough for you to be able to screw the plug into place with it. Most spark plug tools use a 3/8 inch drive, so use an extension for the same size ratchet. Rotate the plug and extension clockwise without placing too much downward pressure on it.  If you force the plug to screw in, you may cross the threads in the engine block, which will result in expensive repairs.  Turn the extension clockwise until the plug threads into place inside the engine. If it suddenly becomes hard and then easy again to screw in the spark plug, remove it and start over to avoid cross threading it. Once the plug is hand tight inside the engine, connect a ratchet to the extension and tighten the plug slightly to ensure it will not vibrate out of place.  You will not need to put too much pressure on the spark plug to ensure it’s tight.  Do not overtighten the plug as it may break the spark plug or make it very difficult to remove. If you break a spark plug, you will need a professional to remove it. Take the plug wire you disconnected from the previous spark plug and press it firmly onto the back end of the now secured spark plug.  The plug wire should pop into place on the spark plug when you know it is firmly connected.  You may choose to apply a small amount of electrical grease to the spark plug or wire to ensure a strong connection. Reconnect the battery once you’re done.

Q: Bring your rug outside and hold it over the ground, shaking it back and forth so the dust and dirt falls off. This won’t remove all of the dirt, but it will help get rid of bigger chunks that aren’t so ingrained into the sheepskin. This will prevent your sheepskin rug from becoming matted after it’s wet. Use either a regular brush or a brush specifically designed for sheepskin. Work your way across the whole rug, combing out any knots.  A wide-tooth comb works well too. Work slowly and gently to prevent damaging the rug. Your rug should have come with a label attached to it, telling you how to properly care for the rug so it stays healthy and presentable. Read the label, looking for the recommended way to wash the rug, such as hand washing or whether it can go in the washing machine on the delicate cycle.  If you can’t find the label, don’t worry. Opt to hand wash the rug just to be on the safe side. If your rug is small, or about the size of a doormat, you can put it in the washing machine. If you have a larger rug, hand washing it is best. It may damage your washing machine or not wash well on a delicate cycle.
A: Shake your rug outside to get rid of excess dirt. Brush your rug before washing to remove any tangles. Read your rug’s label to see what kind of washing is recommended.

Article: You only have five minutes left, but don’t focus on that or worry about how badly you might do on the test. Clear your mind and try to think only about the material you remember learning that you will be quizzed on. During a study of highly anxious ninth graders taking a biology final, it was found that the students who took a couple of minutes to write down what they were worried about with the test did better on it than those who sat quietly during those couple of minutes. This technique tends to work especially for people who are constant worriers, because worrying clouds your thinking and causes you to miss questions that you may actually know. Make a quick list of the biggest points from the material: characters and plot, formulae, or important dates and events. Try to do it from memory, but if you can’t, glance at your notes for a couple of minutes first and then get writing. You may actually have more than five minutes if you remember about the test early enough. You could use the ride to school, lunch, recess, or between classes, before the class that the test is in.
