In one sentence, describe what the following article is about: Your parents will be impressed if you are polite with them, but they will be even more impressed to see you behave politely with other people, such as grandparents, family friends, etc. It may sometimes seem as though you already know everything there is to know about your mother or father, but you most likely know very little about their lives before you existed. Ask them to tell you about their favorite childhood memories or ask them if they have any hobbies they'd like to spend more time on. If you have siblings, do what you can to avoid fighting with them. This can be very challenging, but it is very stressful and even sad for parents to see their children not getting along. This shows your parents that you are maturing. If you can, try having a private conversation with your sibling to explain that you want to avoid disagreement in order to make your parents happy, you may be able to work together to accomplish this step. If your parents have given you a curfew, then be sure to adhere to it. If you are going to be late, call them before you are late to explain why you will be late, and what time you expect to be home. Don't be late because you simply wanted to stay out longer. Your parents will be very worried if they suspect you are doing things that are illegal. They want you to be safe and healthy, but they are concerned because of the potential legal ramifications. Unless you are of legal age to do so, do not drink alcohol. Explain to your parents that you are not interested in trying illegal drugs or drinking alcohol when you are underage because you know that it is dangerous and because you do not want them to worry. If you do get into trouble, be straightforward and honest with your parents about what happened and why it happened. Accept the consequences of your actions. Your parents may punish you for your behavior. If they do, accept this punishment without a fight. This demonstrates maturity. Explain to them how you plan to avoid repeating your mistake in the future.
Summary: Behave politely with everyone you meet. Take an interest in your parents' lives. Avoid fighting with your siblings. Come home on time. Avoid doing drugs or drinking alcohol. Be straightforward.

In one sentence, describe what the following article is about: The first thing you have to do is find out if your gold is real. Separating your gold by its karat weight will not only help you begin to assess its value, but it can point out items that are not even gold. If it is unreadable, you could choose to have the gold tested by a reputable dealer. There's also the possibility that some of the gold is actually just gold-plated, which a dealer would determine with certainty by performing a chemical test. Take note that much of the gold jewelry manufactured before 1980 is slightly below its marked karat value. For example, jewelry marked 18K would actually be between 17K and 17.5K. In 1980, the laws regarding the marking and purity of gold jewelry were changed. If you're still uncertain as to whether or not an item is gold after inspecting it with a magnifying glass, prepare to test it. You have two options here: the acid test and the Skey test. The first, the acid test, will require a gold testing kit or the individual parts that make one up (the acid and stone). Supplies for this test can be purchased from online or physical jewelry suppliers for a small price, and are available separately or as a set. A kit will come with 10K, 14K, 18K and 22K bottles of testing acid, which will normally be nitric acid. It will also come with a test stone, also known as a streak stone or touch stone, that will be made from many different materials, including novaculite or other types of flint material. Kits can also be purchased with an accompanying scale. For suspected 14K jewelry, rub the item on the stone and place a drop of 14K acid onto the mark it leaves. If your item is indeed 14K gold, it will stand up to the acid and not change. If it is 10K, the 14K acid will turn it brown. If it completely disappears, it isn't even gold. If it is an unmarked item, go up to the 22K acid incrementally until it turns brown, and when it does, consider it to be the next lowest karat. For example, if the 18K acid has no effect, but the 22K acid turns it brown, then consider your item to be 18K. If the 14K acid has no effect, but the 18k acid turns it brown, consider it to be 14k, and so on for other karat fineness tests. For the Skey test, start by purchasing a gold tester or gold verification pen employing the Skey method. These testers sell for under $50 and can give a 1000 tests. This test is a safe alternative to acid and will test accurately on metals such as white gold. For all suspected jewelry, Slowly write a inch line and go over the same line 4 times without removing the pen tip from the test metal. Immediately write a line on any white paper. If it is under 10k, the line will be light brown and turn green within seconds If it is 10k, the line will be light brown. If it is 14k, the line will be dark brown. If it is 18k, the line will be orange. If it is 22k, the line will be yellow. If it is 24K, the line will be red. If there is no line at all, it is not gold. If you have gold coins, they may have a numismatic (coin) value which is above their metal value. This tends to be based on age, rarity, and overall condition. In this case, your best option is to take it to a coin dealer for assessment. This is definitely worth doing, as you may be able to get more money that way. If you have experience auctioning items online, you may be able to sell the coin online, but you may need a certificate of authenticity to persuade buyers to pay top dollar. It also makes sense to have a secure payment system in place to make customers feel safe with their transaction. The benefit of an auction (provided you're aware of the coin's real value) is that it may go well beyond your asking price if several collectors are bidding for the coin. Read How to determine the value of bullion gold coins for more details on assessing their value.
Summary: Use a magnifying glass to decipher the karat number on each piece. Perform an acid test on any items you are unsure of. Use the Skey test. Keep gold coins separate from the rest of your gold.

In one sentence, describe what the following article is about: Your child is probably already familiar with the concept of guessing. Explain that estimating is similar, but that the goal is to make educated guesses that are as accurate as possible. Learning how to estimate effectively will let you save time and energy in situations where an exact number is unnecessary. If you pay attention, you'll see examples of estimation frequently in your daily life. You might, for example, estimate how much your grocery bill will be, how long it will take you to drive somewhere, or how many cups of milk are left in the carton. Explain these examples to your child in a developmentally appropriate way. When you give these examples, it can help to explain why estimating, rather than calculating, is appropriate in the particular context. Tell your child, for example, that if you needed to know exactly what your grocery bill would be, you could add up all the prices and get a precise number, but, in this case, you're only trying to get an approximate number so that you don't spend too much. To reinforce the concept, show your child a flash card or picture with multiple objects on it: animals, toys, whatever your child likes. Show the card to your child, but not for long enough to count the objects, then ask your child to estimate the number. Give high scores to close estimates. Repeat the game until your child seems to understand the concept.
Summary:
Explain that estimation is like guesswork. Give examples. Use flash cards.
