Article: While plastic plants may not sound that appealing, many of today's products can actually look quite lifelike. Like live plants, you can use plastic plants to hide your filtration system. You might also try some plants that are about mid-height in the center of the aquarium. Smaller plants can go around rocks and other items. Just make sure you buy plants that are approved for fish tanks. You don't want to place something in the tank that could harm your fish. Most pet stores sell novelty items to add to your tank. You can find anything from treasure chests to plastic divers and mermaids. These items are great for creating a particular feel. You can make your tank feel like the bottom of the ocean with a pirate ship and treasure chest, which also adds a sense of adventure. You could create a fantastical world with tiny fake squid, mermaids, and other fantastical novelty items you can find. Many of these items pertain to an ocean theme, so your choices may be a little limited. Choose items that are made for fish tanks, as other plastics may leach over time. Ceramic pieces can add an artistic touch to the aquarium, as they can be painted in a wide variety of patterns. You can use ceramic pieces to create a color theme or set a certain mood because they come in so many different styles and colors. Try bright Mexican-style pieces for flair and color. You could even pick pieces that have a nautical theme. Add a few plates at the back as a backdrop to your tank or a vase on its side for fish to swim in and out of. For a bit of class and whimsy, consider a few mismatched teacups and saucers or even a whole teapot if your tank is big enough. Mugs and other similar dishes can also create hiding places for your fish. You can purchase ceramic pieces at almost any big box store or decorating store. However, you should check to make sure your pieces are safe. Any unglazed ceramic piece is fine. If it's glazed, it should be labeled "food safe," "dinnerware safe," or be sold as dinnerware. If it's safe for you to eat off of, it should be safe for the aquarium. Another option that you can do for free is to upcycle old jars or bottles. Pick bright colors, like green or blue, which help create a beach-like feeling, as they're reminiscent of beach glass. Clean them out thoroughly, and remove the label. Make sure you get all the glue off. Then you can set the jar on i's side in the aquarium, making another place for the fish to play in. Glass is best because it won't leach chemicals. Try a blue or green jar, which will add color to the aquarium.

Problem: Article: Biology textbooks have really good questions at the end of each chapter that reinforce the concepts that you need to understand from the material. Try answering the questions and see how many you can get through. Take note of the questions that are more difficult to answer. Revisit your notes on these topics and/or reread that part of the chapter. If you're having a lot of difficulty answering these questions, seek extra help from your classmates or teacher. Avoid walking out of class and forgetting about everything you just learned. Reviewing your notes later that evening or the next day can help you synthesize what you have learned. When reviewing, ask yourself if everything makes sense. If something stands out that confuses you, reread the material on that concept in your textbook. If it still doesn't make sense, ask your teacher about it in the next class. Because biology can be difficult for many students, you must put in the time to do well. If you set aside time every night or every other night for biology, you will get into the good habit of frequently studying. You will thank yourself later when you don't have to cram for the exam because you have been reviewing everything this whole time. Stick to your study schedule and make it a habit. If you skip 1 day, be sure to get back on track the next day and not let yourself slip into not studying multiple days in a row. Even if you're busy, plan to spend 15 minutes per day reviewing your notes. This can make a big difference! Creating mnemonic devices can be really helpful when studying biology. For instance, you could create a mnemonic to help you remember the order of the substrates in the Krebs cycle. A phrase like, "Citrate Is Krebs Starting Substrate For Making Oxaloacetate" can make it easier to remember Citrate, Isocitrate, Alpha-Ketoglutarate, Succinyl CoA, Succinate, Fumarate, Malate, Oxaloacetate. If you have access to exams from previous years, try taking them and see how much of you get right. If you don't have access to these, study your quizzes and previous tests for an idea of the types of questions you will get asked. Answering questions from old tests will give you an idea of what you need to keep studying and what topics you have mastered. You could also make up your own quizzes to test yourself on the material. Focus on the concepts you have the most difficulty with. This helps you process the information in a meaningful way, instead of just trying to memorize it.
Summary: Answer the questions at the end of each chapter. Review your notes within a day of each lecture. Set aside time specifically for studying biology. Use mnemonic devices. Study old quizzes and exams before tests.
