Problem: Article: Make sure your passport is up to date and won't expire before your trip ends. Different countries have different requirements for passports and visas, but in general, your passport should not expire less than 6 months after your expected return date. The country you're going to may require you to have certain vaccines up to date. Make an appointment with your doctor to get this taken care of, as well as other medical considerations. Check you have the appropriate cover, and look into international health insurance. Chances are that you will never fall ill while traveling abroad, but it has happened. Bones have been broken; people have gotten food poisoning; pregnant women previously cleared for travel have gone into premature labor. Consider whether the added expense is worth being "safe rather than sorry". Housing choices are largely a matter of budget, comfort, and convenience. You can pay for a private hotel room or share a hostel; stay with friends or family; or explore online travel communities like Couchsurfing.com, AirBnB, or WWOOF.org.  Think about staying in an apartment if you'll be in one place for more than half a week. Hotels can be expensive, and you can often get much better deals for renting out someone's house. Furthermore, this approach might give you a more authentic idea of what it's like to live in a given city. Consider a Bed and Breakfast or a self-service vacation rental. This last type of accommodation can help save money, as they're often cheaper than hotels, and you'll save money by buying your groceries and cooking there instead of going out to eat. Your options are broad and varied, and you'll have to choose the best mode of transportation to suit your itinerary. If you will be traveling long distances between destinations, you might consider flying or taking trains. If you'll be traveling within a city or region, try biking, renting a car, or using public transportation. Research the place you're going and try to understand how the locals get around.  Trains can be relaxing over long distances. Consider taking night trains – in theory, you can sleep on the train and awake as the train pulls into your next destination! If you plan to rent a car, look into insurance requirements. Consider applying for your international driver's license. Ferries are a solid option for crossing water. They are usually cheaper than another plane ticket, with better food. If you plan to travel with your pets, look at the rules and regulations for traveling with them to keep them out of quarantine. This generally includes a certificate of health from your vet, making sure that rabies vaccines are up to date, having them microchipped, and even a certificate of health from your local government office, such as  the Department of Agriculture in the U.S.
Summary: Prepare your travel documents. Look into vaccine requirements. Get travel insurance. Decide where you're going to stay. Figure out how you're going to get around. Don't take animals, plants or anything else that's not accepted on flights.

Problem: Article: A free study option is always a study area in your school library, where you can be surrounded by other students who are focused and diligently working on their own study materials. Many school libraries will have quiet areas or zones for studying and encourage students to use the school space to prepare for tests. If you are planning to study with a partner, you may be able to book a private study room where you can discuss the test and share review materials. This will ensure you can talk to your study partner without disturbing anyone around you. Talk to the circulation desk at your library about booking a study room or look at your school’s library website for more information on booking a study room. If you prefer to study in the cozy atmosphere of a nearby coffee shop, be sure to bring headphones with you. They may come in handy if you are around people who are talking loudly or having a conversation close to you that is distracting. Some coffee shops are known for their quiet environment, especially if they are located on school campus and are frequented by many students. Consider choosing a coffee shop that is known for its student friendly atmosphere, rather than a coffee shop that is loud, bustling, and often crowded. This will ensure you will be able to get work done without being constantly interrupted or distracted by noise and chatter around you. Some students prefer to study in the comfort of their home in their bedroom or in a room in the house that is free of distractions. You may want to set the scene if you are studying at home to make it the most study friendly.  This could include telling everyone in the house that you are studying and shutting the door. Or, you could turn off any distractions, like the television, a radio, or your cellphone, and place them out of reach. This could then help you to focus on studying for the science test. While it may be tempting to lie in bed as you study, data has shown that studying in bed can lead to distraction and difficulty turning off your brain when it’s time to go to bed. Instead, study at a desk in your room with a desk lamp so you get enough light and can focus on your study materials.
Summary: Look for a quiet study area at your school library. Choose a secluded spot in a local coffee shop. Study at home in an area free from distractions.

Problem: Article: In scientific terminology, a fact is an observation that has been repeatedly observed and is accepted as practically functional and “correct.” While facts can be scientifically refuted or may not be consistent across time and place, they are held as true until they have been proven wrong. As you explain this concept, focus especially on separating fact from law, since both describe natural phenomena, albeit in different ways.  When explaining a scientific fact, start with a point of general observation. For example, begin your explanation by saying something like, “it is always bright outside at noon.” This is a fact in that it describes a state of nature—however, this statement may not be true in Antarctica or Greenland, where darkness lasts throughout the day in certain seasons. Explain how this will lead to a revision of the scientific fact: “within certain degrees of latitude, it is always bright outside at noon.” Facts are often the initial building blocks of scientific inquiry; they can generate curiosity and the hypotheses that come from inquiry and experimentation.  Facts are less formal than laws, and are not seen as an “official” definition of a phenomenon that occurs or of the reason that something happens. Facts are more localized and generalize less than laws. Explain that, if the Law of Evolution describes the way that species throughout the world evolve over time, a scientific fact related to evolution (and natural selection) could be: “giraffes with long necks can reach more leaves than giraffes with short necks.” Many students and adults hold to misunderstandings of scientific vocabulary and misunderstand the relationship of theories, laws, and facts. For example, scientific theories do not develop into scientific laws. To explain the difference, focus on this distinction: laws describe phenomena, theories explain phenomena, and facts describe observations.
Summary:
Define a scientific fact. Provide examples of scientific facts. Clarify the distinction between scientific laws and facts. Clear up any common misconceptions.
