In one sentence, describe what the following article is about: 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 C80000C81399. 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: Hydrangeas are made from multiple small sections glued together, so make sure you have a fairly sizeable piece of felt to start this project. You can use multiple colors for a single flower if you want.
Summary: Select your felt. Finished.

In one sentence, describe what the following article is about: Bullies get satisfaction from seeing their victims react to their taunting. If your child starts ignoring the bully and walking away when the taunting starts, the bully can lose interest. Sometimes your child will be in a situation when he can't walk away, like in class or on the field. In this case, you child has to ignore the taunts and teasing to disarm the bully. Acknowledge to your child that this is very difficult to do. It is definitely easier said than done, and your child might resist this idea when you bring it up. It would help if you did some exercises with your child to help control emotions. Tell your child to close his eyes and count to ten when feeling angry or sad. Deep breathing exercises can also help control emotional responses. If a bully refuses to leave your child alone, you can encourage him to stand up to the bully. Bully's like to pick on weak targets, and will often back down when someone stands up against them. Tell your child to say firmly, "Leave me alone!" the next time the bully bothers him. Never advise your child to physically attack the bully. This won't help the situation. Bullies are usually more likely to go after victims when they are alone. Your child can avoid this by sticking with a friend or classmate whenever he goes somewhere the bully might be. If these methods don't work, your child needs to seek help from another adult. A teacher, principal, or coach might not even be aware that there is a problem, so your child has to report it. These people can take steps to prevent the bullying. After your child initially tells you about the bullying, it will probably be easier to talk about it in the future. You must, however, make sure you keep checking in with your child regularly. Ask how these methods are working and if the situation is getting any better. If nothing is working, you might have to step in and take more active measures.
Summary:
Advise your child to walk away from the bully. Tell your child to ignore the bullying if he can't walk away. Advise your child to stand up to the bully. Use the buddy system. Let your child know when to get help. Keep the lines of communication with your child open.
