Problem: Write an article based on this summary: Take notes efficiently, not thoroughly. Use an outline format for your notes. Save class handouts. Learn your teacher's teaching style early. Let the teacher explain homework in class.

Answer: Some students try to write down everything the teacher says, but that's far too much work. In some cases, it might even makes it harder to figure out what's actually important enough to be on a test because you just have too much written down. Furthermore, people get so busy trying to write quickly that you don't focus on the lecture. You'll end up with bloated, messy notes that you don't understand because you weren't paying the right kind of attention to the class discussion. It's easier and more effective to listen to a lecture than it is to transcribe it. Sit back, listen, and write down only the information you think will be on the test. If the teacher writes something on the board, they're trying to draw your attention to it for a reason. Write it down. It doesn't require any more effort than taking sloppy, disorganized notes, but writing down your class notes as an outline will show you the connection between ideas later, when you have to go back to your notes and study for a test. Use a clear hierarchy of indentations so you can easily tell the difference between major points and minor/supporting details. You can disregard some of the supporting details when studying for a test. If your teacher took the time to create a handout to go along with a lesson, there's a good chance that the information on it is what your teacher considers to be the most important material from the lecture. There's a better chance of this information being on a test, so focus on the handouts instead of trying to take notes on an entire lecture. Store handouts neatly in folders or three ring-binders Use one folder per class; if you mix up your class materials, you'll create more work later when you need to study. Every teacher will have their own little quirks. At the beginning of the year, spend some time asking students who've had your teachers before what you should expect from them. Observe your teachers closely for the first couple of weeks to figure out how what makes them tick. The better you know your teachers, the more easily you can give them exactly what they want without having to run yourself ragged. Do any of your teachers go off on long, unrelated tangents on material that won't be on the test? Feel free to zone out on unimportant information. Get to know their speaking styles. Some people use vocal emphasis to draw attention to important information that will be on tests, whereas others might use exaggerated hand gestures to highlight information. How do your teachers grade homework and classwork? Some might assign point or letter grades to small daily assignments, but if everyone just receives a check mark for completion, then you don't have to work hard to earn your daily credit. Especially if your teacher gives equal credit for everyone who completed the homework assignment, don't put more effort than you need to into completing your homework. Often, teachers will go over the answers to the homework in class the next day, and you will get answers to questions that might end up on tests without having to comb through a whole textbook to find them. Use your discretion about whether or not this step will work for your individual teachers. Some teachers don't go over homework and readings the next day; in those classes, it might be worth it to spend time on your homework.

Problem: Write an article based on this summary: Get an aquarium. Find an appropriate spot for the tank. Fill the tank with water. Add hiding spots.

Answer: A proper habitat is key to caring for your piranha, so create a home as close to the fish's natural habitat as possible. Many people suggest getting a tank large enough for 4 piranhas to best mimic the natural environment. However, you may want less. Get an aquarium of at least 25 gallons for one piranha or 60 gallons for four piranhas to properly house them. Buy a tank that corresponds with the number of piranhas you'll have. For example, if only want two animals, a 40 gallon tank should be enough space for them. As a rule of thumb, you want about 20 gallons of water per animal or 60 gallons for 4 piranhas. Make sure to the biggest tank you can afford so that your piranhas can flourish. If you're trying to save money, consider a second hand tank. Wash any tanks before introducing your piranhas to them. Consider getting an optional tank screen for the top. Piranhas can jump and injure their owners if they're hungry. You also want to ensure that pets or small children don't fall in the tank. Piranhas are messy animals that are also surprisingly timid. In addition, direct sunlight or heat can encourage the growth of bacteria that can harm your piranha. Placing the tank in a spot that is not exposed to extreme heat or lots of traffic can keep your piranha happy and healthy. Put the tank in a place with a relatively consistent temperature of 75 to 80 degrees Fahrenheit (21 to 25 Celsius). Attach a thermometer to the aquarium to monitor the temperature. You shouldn't put the tank anywhere it may get direct sunlight or be exposed to radiators or heating devices. Find a low-traffic space in which to put the tank. If there are too many people walking by the tank, it can stress out piranhas and may make them aggressive. Consider putting the tank in a space with low light. In the wild, piranhas live in murky water that is under the canopy of the rain forest so their eyes have adapted to dimmer lighting. Piranhas are surprisingly hearty fish and can adapt to different water conditions. In general, they live in warm, fresh water between 75 to 80 degrees Fahrenheit. They also thrive at a pH of 5.5-8.0. You can fill the tank with warm tap water as long as you're using several filters in the water. In addition, you should keep a temperature in the water to ensure it is optimal for your piranhas to thrive. Add several small filters to the water or one very powerful external filter to keep the water clean. Consider getting a heater for the water to keep the water a consistent temperature. Because piranhas are shy, they like to hide. Putting some decorations in the tank can help keep your piranhas happy and healthy. Decorate the tank with live and plastic plants as well as smooth gravel, and pieces of wood. Be aware that Piranhas may destroy live plants. A clean piece of PVC piping can also provide piranhas a place to hide if they feel stressed. Choose decorations that you like. You can use live or plastic plants or a combination. If you're using live plants, consider hardy, low-light options such as hornwort, java moss, or fern. Any type of plastic plant you like will work. Soak any wood or driftwood in a tub or bin until it turns a brownish color. Many piranhas like the dark color of the water, but it may be difficult to see your fish. Make sure the driftwood fits in the tank and gives your piranhas plenty of space to swim freely. Use smooth rocks and gravel that only barely cover the bottom of the aquarium. You can safely use granite, basalt, gneiss, slate, and quartz. Avoid limestone, marble, dolomite, calcareous sandstones, chalky rocks as well as corals and sea shells. All of these can upset the pH of the tank. Place as many decorations as you like in the tank, but remember that your piranhas should be able to swim freely without hindrance. A good rule of thumb is 50-75% coverage in the tank to make your piranhas feel comfortable. Too many decorations can also more quickly decrease the water quality.

Problem: Write an article based on this summary: Use only safe, edible flowers and plants in your soap. Refrain from adding fresh plant elements to your soap.

Answer:
Do your research beforehand to make sure your chosen flowers are safe for soap making. A good rule of thumb is that if they're safe to eat, they're likely safe to put on your skin as well. Dried flower petals can look pretty in handmade soaps. Try hibiscus, rose, lavender, chamomile, goldenrod, and calendula. Try using dried plants such as eucalyptus leaves or dried citrus peels to add fragrance and color to your soap. Steer clear from non-edible and toxic flowers like dahlias, oleanders, foxgloves, or lily of the valley. If you're not sure about the safety of a particular plant, research it online or refer to a botanical safety guidebook. Fresh herbs, flowers, fruits, and leaves can lead to mold and bacteria. Avoid using fresh plants to keep your soap safe, sanitary, and long-lasting. The only plants you should try fresh are lavender, rosemary, and thyme. The leaves of these herbs are pretty dry to begin with, and they can look attractive when used whole at the top of the soap. Avoid mixing them into the liquid glycerin, though.
