Problem: Article: Since copper is quite soft, it should produce a muted, round sound. A test way back in 1867 described copper's sound as "dead," while brass emitted a "clear ringing note." This might be tough to judge without experience, but learning it could prove useful for an antiquing or scrap collection hobby. This works best for thick, solid metal objects. Brass objects made for industrial purposes often have a code stamped on them to identify the exact alloy. In both the North American and European systems, the codes for brass begin with a C and are followed by several numbers. Copper is often left unlabeled, but if you want to be sure, double check the code with this quick guide:  The UNS system in North America uses brass labels beginning with C2, C3, or C4, or fall between C83300 and C89999. Copper, if labeled, can use codes from C10100 to C15999, and C80000–C81399. The last two digits are often dropped. In the current European system, both copper and brass begin with C. Brass ends with the letter L, M, N, P, or R, while copper ends with A, B, C, or D.  Older brass may not conform to these systems. Some older European standards (which were used quite recently) list the element symbols followed by a percentage. Anything that contains "Cu" and "Zn" is considered brass. This test is usually not too helpful, since brass is only slightly harder than copper. Some types of treated copper are particularly soft, so you may be able to scratch them with a US penny (which is never true of brass). However, in many cases there is no convenient object that will scratch one object but not the other. Copper is easier to bend than brass as well, but it's difficult to draw exact conclusions from that test (especially without damaging the object).
Summary: Strike the metal and listen to the sound. Look for stamped codes. Check how hard the metal is.

In one sentence, describe what the following article is about: Do you routinely prepare for trash day, sweep up when necessary, and pitch in toward a functional house? Many of these tasks may be considered part of your chores or expectations, but extra effort may be rewarded. Most parents like to see their kids attempting to be responsible with money, so ask them for a weekly or monthly allowance.  Negotiate a fair amount of money for the work that you do. Don't expect them to pay you $/£20 for nothing. They may expect you to complete a few more household chores since they are paying you regularly. Think about how you will justify this allowance. Why do you need it? Why do you deserve it? Be prepared to give your parents good reasons if asked.  Common tasks that parents pay their children allowance to complete include: cleaning your room, emptying and loading the dishwasher, vacuuming, washing and folding laundry, and dusting. Look for opportunities for some extra cash in less common tasks. Think of any "someday" projects your parents have been talking about. Does Mom keep saying she needs to organize her tools in the garage? Does she always talk about reorganizing the pantry? Does Dad want his shop organized? Great! Come up with a plan to complete those tasks and present it to your parents along with your asking price. Present a reasonable plan with a realistic price and, after a little follow-through, you've got a payday. If you are trying to make money from your parents, don't hurt your chances by acting up. Arguing with your siblings, talking back to your parents, and breaking the rules may result in them taking away your allowance or punishing you by requiring you to do the work for no money. If your parents give you money for drinks, snacks, or sweets when you go to school or out with your friends, spend that money smartly. Instead of using all of it, maybe limit yourself to a can of coke or lemonade and put your other money away for later. That way you can still enjoy yourself, but save a little for later. If your parents send you into a store to pick up a few items, ask them if you can have the change. If they expect the money back, ask them can you keep the coins. Pennies, pounds and other coins quickly add up. If you've already got a savings account, talk to your parents about moving your money into an account which gains interest - that is, one that grows your money. They might not know much about these accounts, and that's okay. Ask if they would go with you to a bank or credit union so you can all ask questions about ways to save and grow your money.
Summary:
Request an allowance. Offer to complete special tasks. Be respectful towards your family. Use the money your parents give you smartly. Grow your savings.
