In one sentence, describe what the following article is about: The boxes will be the molds that you'll use to create the planters. Find 1 large box and a slightly smaller box. The smaller box should be able to fit inside of the larger box. The space in between the 2 boxes will determine the thickness of your concrete planters. The boxes can be made of cardboard or wood. The smaller box should be at least 2 inches (5.1cm) smaller than the big box on each side. The smaller box should be at least 8 inches (20cm) deep for larger plants and 34 inches (7.610.2cm) deep for smaller plants. Get sturdy boxes so that the mold doesn't break when you fill it with concrete. If you want a concrete planter that's a different shape than a rectangle or square, you can purchase plastic containers of any shape to serve as your molds. Find 2 different sized plastic containers online or at a department store. The smaller container should be at least 2 inches (5.1 cm) smaller than the larger container around each side. The smaller container should be at least 8 inches (20 cm) deep for larger plants and 34 inches (7.610.2 cm) deep for smaller plants. For instance, you can get 2 pots or 2 plastic bowls. Stretch the trash bag over the smaller container so that it's taut against the sides. The trash bag should be tight against the inside of the container as well. Tape the trash bag to the box or container with duct tape. The plastic bag will prevent the concrete from sticking to the small container and will make it easier to remove the mold. Use a ruler to measure 2 inches (5.1cm) from the base on the inside of the large container. Make a horizontal line with a pen or marker. This will help you determine how much concrete you should initially pour into the mold. If you want the sides of your planter to be thicker, measure and mark the line to reflect the change in dimensions. For instance, if your planter's walls are 4in (10cm)-thick, you'd measure and mark 4 inches (10cm) from the base of the planter. Spread the non-stick spray around to get an even coating on the inside of the larger box. The cooking spray will make it so that the concrete doesn't stick to the sides of the larger container. You can purchase a can of cooking spray online or at a grocery store. You can coat the inside of the larger box with mineral spirits as an alternative to cooking spray. Pour the spirits into the bottom of the box and spread it around on the inside of the box with a rag.
Summary: Get 2 different sized boxes. Use plastic containers rather than boxes. Tape a plastic trash bag around the smaller container. Mark 2 inches (5.1cm) from the bottom of the large container. Coat the inside of the larger box with cooking spray.

In one sentence, describe what the following article is about: Writing down the information yourself--rather than borrowing a set-- is more effective. The process itself helps the learning and memorization process. Plus, this will help you summarize the information in a way that makes the most sense to you. It can be tempting to borrow someone else's flashcards, but this won't help you nearly as much as making your own. When you make your flashcards, make sure you write them on thick cards or paper. You need to make sure you can't see through the paper to get the answer on the other side. If you are making your own cards, be sure that they are all the same size. You don't want different sizes of cards giving away the answers. Otherwise, you aren't memorizing the connection between the terms and explanations, but just what each size card says. That won't be very helpful when you're taking the test. A package of index cards is usually a great starting point, as they will all be the same size and made of nice, thick paper. Plus, one side usually has lines, helping you write neat sentences to explain concepts. Of course, it is better to use regular paper if you must than no flashcards at all! Avoid waiting until the night before the exam to put together your flashcards. Instead, make a nice pile right after class or school. That is when the information will be freshest in your mind, and you won't have to try and remember everything when you start making the cards. This is also a good way to come up with questions to ask your teacher. If while making your cards, you come across a term that you can't write a good card for, ask your teacher about it in the next class. Write down the answer on the back of your card, and you've got a pre-made flash card ready to join the others. In general, limit your cards to one word or one sentence. The less you need the remember for each card, the easier it will be the memorize it. Make sure you keep your information on each card limited to just a few words of information. For example, if you are studying for a history class, and are making a card for George Washington, you'll want to limit your information. Using small bullet points like "Commander during the American Revolution," "First President of the United States," and "Father of the Country" is better than a paragraph listing every detail you can cram onto it. If you are using your flashcards to ask and answer questions, keep to one question per card. For a history card, don't ask "Who was the first President, Vice President, Speaker of the House, and Chief Justice of the United States?" That is too much information at once. Not only will you have a hard time memorizing each piece of information, but also remembering which one is tied to which. In addition to the words on your cards, consider including a picture. Your brain is really good as remembering visual images, and adding them to your cards can help you associate them with words. These don't need to be detailed drawings, just simple designs to help remind you of what you are looking at. This is particularly helpful for flashcards to study a foreign language. In addition to the vocabulary you are trying to use, sketching a small picture can help the word stick in your mind. While handmade flashcards are a common study tool, there are many new technologies out there for creating electronic cards. You can store these cards on a smartphone or laptop and have them accessible wherever you go. There are many different programs available for free that allow you to create a database of cards from your own notes as well as other people's work. These programs can create games and other study methods to help you with memorization. Common software and websites for digital flashcards are Quizlet, Memrise and Anki. Sometimes they also couple with flashcards with spaced repetition.
Summary:
Make your own cards. Use thick paper. Make your cards early. Keep your cards simple. Use pictures. Use electronic flashcards.
