Problem: Article: The study of chemistry is generally divided into five broad categories, each with its own sub-disciplines and unique methods of study. If you understand what broad field of chemistry you're studying and what that means, you'll be grounded and ready to learn particularities within the field. The five categories are: Inorganic chemistry: the study of structures and compounds of substances made from all elements, except carbon. Organic chemistry: the study of the compound of carbon. Physical (or theoretical) chemistry: the application of mathematical methods to chemical problems. Analytical chemistry: quantitatively and qualitatively analyzes chemical compounds. Biochemistry (or physiological chemistry): the study of chemical reactions within living cells and the chemical structures of living material. This will increase your familiarity with the material, and class itself will clarify questions that came up when you read the material, rather than raising questions. Reading materialsuch as book chapters and reading that will be covered in class will familiarize you with the topic ahead of time. This technique is known as a "Flipped" or "Reversed" classroom, and has proven useful in multiple fields. This should help make learning easier, since the instructor is there to clarify and explain information. Don't take this time for granted, but actively focus on apprehending every point your teacher makes. Attend class regularly. As mundane as this can feel, regular attendance will ensure that you don't miss the explanation of new topics. It's easier to keep up with the class lessons than to catch up. Don't hesitate to bring up your concerns in class if you are confused about any points, equations, or topics. No question is too small to ask; if you're confused about a point in the lecture, it's likely that other students are too. Discuss with your teacher or with your classmates if you have any problems with the chemistry topic. If you're struggling to understand a concept, ask your instructor for study guides or worksheets. You can think of this as writing a "summary" of class: what did the teacher lecture about; what new topics or equations were introduced; what relevant questions were asked and how where they answered? This is especially important in the chemistry classroom. New concepts and equations will be built on those that you've covered earlier in the semester (or quarter), so it's important that you understand ideas of chemistry. Having these written in your notes will help you remember. Pinning down the important points that your instructor has presented in a class period will help you to understand key topics and ideas. You can also review notes while working on your homework after a chemistry lecture. It's best if you review your notes shortly after the class; if you wait until the weekend, you may have forgotten some of the material already. Take advantage of your school's study-hall period to review notes from chemistry. You may find it easier to retain concepts when reading them from your own notes rather than from a textbook, since you will have already written the concepts in terms you understand.
Summary: Grasp the category of chemistry you're studying. Read the assigned chemistry material before going to class. Listen to your chemistry teacher in class. Ask questions. Take plenty of notes. Review your notes from class.

Problem: Article: The swelling usually appears one week after the bite. The bite site becomes a boil-like, hard and violet colored lesion that may persist for several weeks. The swelling is due to multiplication of the parasite locally in the tissue that leads to inflammation. It is known as "Chagoma". A chaga bite may be confused with other types of insect bites. However, the swelling of a bee sting or ant bite develops quickly and is extremely itchy while the swelling of a reduviid bug bite is less itchy. If the parasite infects the conjunctiva there may be painless, non-itchy swelling of the eyelids. Your eyelids will then appear firm and reddish. They may also take on a purple hue. This symptom is known as Romana's sign. There may also be swelling of the surrounding area if the infection spreads locally. This is a very reliable sign of Chagas disease. While other diseases can cause your eyelids to swell, chaga is the only one that results in painless, non-itchy swelling. Lid swelling due to bacterial or viral viral infections will be painful and itchy accompanied by watering. A stye caused by a bacterial infection causes development of boil like swelling in a single lid. Your fever will most likely be non-specific and low grade. It may also appear as a fever that lasts for a few hours a day and then disappears for the rest of the day and night. Chagas may cause a transient, non-itchy skin rash that resembles the rash you get when you have measles. Luckily, it is usually self limiting and resolves within a few days. Lymph nodes close to the site of infection might become swollen after the bite. The parasites will travel along lymph vessels to reach those lymph nodes where they induce inflammation. Swelling of the lymph nodes means they are responding and trying to kill or eliminate the invading organisms. Lymph nodes fight against infection and are found in different parts of the body. In normal individuals, the lymph nodes cannot be felt or palpated. They are located beneath the skin of armpit, angle of mouth or neck. There may be loss of appetite, feeling of nausea, or the development of vomiting or diarrhea. However, these digestive problems are non-specific and result from many different health issues, so they are not the best measurements when trying to determine if you have Chagas or not. These are also non-specific symptoms. Fatigue may develop because of the acute stress the infection is putting on your body. When the body recognizes an infection, it fights against the invading organisms, which in turn causes you to feel tired. A feeling of pain at different sites in the body is generally due to the toxic substances that are produced at the site of the infection and inflammation.
Summary: Look for swelling at the bite site. Watch out for swelling of the eyelids. Keep track of any fever you experience. Pay attention to any sudden rashes. Check to see if your lymph nodes are swollen. Note any digestive problems you experience. Monitor fatigue and body aches.

Problem: Article: Many websites have people search or white pages functions. Often, you'll find that a phone company hosts the online version of the white pages. The more common the name, the more you may have to narrow it down, since multiple names will come up if it's a common name. You will get the same results as if you looked in the phone book. Any unlisted number will not be available with one of these searches.
Summary: Search for "white pages" and remember to bookmark the site once you find one you like. Type in the state where you believe the person lives and both first and last names for the best results. Keep in mind that you shouldn't have to pay to find someone's phone number.

Problem: Article: The more complicated you want to make the maze, the more tubes you will need. In order to maintain the shape of the tubes, be careful not to force them to fit into each other. Hamsters will nibble at the cardboard, so you want to make sure that the type of glue you use will not make them sick. This will create the shape of the maze. The more creative you are with the directions of the tube, the more challenging the maze will be for your hamster. If you choose to place the maze outside of your hamster's cage, closely supervise your hamster so that he does not escape or injure himself. Other household materials that you can use to create a maze include empty shoe boxes, cylindrical oatmeal boxes, and wrapping paper tubes. The scent of the maze will encourage them to move even faster through it to get to the treat.
Summary:
Gather a handful of empty toilet paper tubes. Place the tubes within one another. Use non-toxic glue to attach the tubes to each other. Place the rows of tubes in different directions in the cage. Place a treat at the end of the maze.
