Magic Rocks Crystal Growing Kit Review

Magic Rocks Crystal Growing Kit Review Compare Prices Magic Rocks are a classic instant crystal growing kit. You pour a magic solution over magic rocks and a fanciful crystal garden starts growing as you watch. Are Magic Rocks worth trying? Heres my review of the Magic Rocks kit. What You Get What You Need There are different Magic Rock kits on the market. Some of them only include the Magic Rocks and the Magic Solution. I bought a kit that included a plastic display tank and some decorations. If you dont get a kit that includes a display tank, you will need a small plastic or glass bowl (a small fishbowl works). For any kit, you will need: room temperature water (~70 °F)measuring cupplastic spoon or wooden stick My Experience with Magic Rocks I grew Magic Rocks when I was a kid. I still think they are fun. They arent a fool-proof project, though. Success depends on one thing: following the directions! Read the directions before beginning this project. The exact instructions will depend on your kit, but they go something like this: Read the instructions.Mix the Magic Solution with the amount of water indicated in the instructions. Be sure the water is room temperature and not hold/cold. Mix the solution well (this is important).Place half of the Magic Rocks on the bottom of the display tank. The rocks should not touch each other or the sides of the tank.Pour in the diluted Magic Solution. If any of the rocks were disturbed, use ​a  plastic spoon or wooden stick to put them back in place. Do not use your finger!Set the container somewhere where it wont get bumped. This location should have a stable temperature and should be out of reach of young children and pets.Look! The crystals start growing immediately. Its pretty cool.About 6 hours later, add the other half of the Magic Rocks. Try to avoid landing them on each other or against the side of the container.After another 6 hours, carefully dump the Magic Solution down the drain. Flush this solution away with lots of water to be sure no one will acciden tally touch it. Gently fill the tank with clean room-temperature water. If the water is cloudy, you can replace the water a couple more times to cleanse the tank.At this point, your Magic Rocks are complete. You can top off the display tank with water to keep the crystal garden as long as you like. What I Liked and Didnt Like About Magic Rocks What I Liked Instant gratification. Crystals begin to grow as soon as you add the Magic Solution to the Magic Rocks. You dont have to wait around for something to happen.The crystal garden is beautiful. Nothing looks quite the same.The project is easy.You can keep your creation indefinitely. What I Didnt Like Magic Rocks are not non-toxic. The ingredients are harmful if swallowed, plus they are a skin and eye irritant. That makes them unsuitable for very young children. Keep them away from pets, too. It is safe to rinse the materials down the drain, but clean-up is a little more critical than with non-toxic projects.You can get poor results if you dont adhere to the instructions. If the rocks are too close together, your crystals will look flat and uninteresting. If your water is too warm or too cold your crystals will be too spindly to support themselves or will be stunted.The instructions dont explain the science behind how Magic Rocks work. In case you are wondering, you arent really growing crystals in this project. You are precipitating colored metal salts. Its still awesome. The Bottom Line Magic Rocks have been around since the 1940s and are still around today because this project is a lot of fun, is easy to do, and makes an interesting chemical garden. I might hold off on playing with Magic Rocks if I had very young children in the house (recommended age is 10), but otherwise, I think they are great. You could make your own Magic Rocks, but most kits are inexpensive. Magic Rocks are a memorable science project. Compare Prices

Which AP Classes Should You Take Planning Guide

Which AP Classes Should You Take Planning Guide SAT / ACT Prep Online Guides and Tips So you’ve decided you want to add an AP class to your schedule. Maybe you want to take even more than one! Good for you – taking AP classes is a great way to start challenging yourself in high school. Now comes the hard part: choosing which AP class (or classes) you should take. This guide will walk you through different factors to consider and help you decide on the best AP classes to take. What Steps Should You Take When Deciding on AP Classes? There's a lot more to choosing AP classes than just choosing a course that sounds interesting or that your friends are taking. AP classes can have big benefits, like strengthening your college applications and earning you college credit. However, if you don't choose your AP classes wisely, you could end up in a class that is overwhelming, boring, and/or drags down your GPA because you can't get a high grade in it. By carefully considering which AP classes to take, you can maximize the benefits you get from them while minimizing the drawbacks. Below are six steps you should take to ensure you've considered all the major factors needed for choosing the best AP classes for you. #1: Consider Your Strengths Before you even look too closely atyour school’s available classes, start by thinking about what topics interest you and which subjects you tend to do well in. AP classes can be very difficult even if you're interested in the subject material, so it would be especially challenging to get yourself to study for something you really dislike, even if you think taking a particular AP class will look good on a college application. Instead, you should aim for AP classes that you are interested in and think you can do well in. Explore our list of AP classes to get started. Also think about your favorite classes so far in high school or even back in middle school. Classes you enjoy are a good predictor of the type of AP class you will like and do well in. #2: Learn What Prerequisites You Need Once you have considered your own personal strengths, also think about classes you have taken that could prepare you for an AP class. You shouldn’t jump into an AP class unprepared! Often your school will mandate prerequisites anyway, like requiring pre-calculus before you can take AB or BC Calculus. Some schools even require you to take a placement test to get into certain AP classes! If your school doesn’t have prerequisites, or if you’re having a hard time deciding between classes, think about all of your past preparation. It can be more than just one prior class. For example, if you’ve taken honors English each year since seventh grade and also write on the school newspaper, you would likely be well prepared for AP English Language or AP English Literature. Conversely, say you took Honors Biology last year and didn’t do too well. AP Biology will probably be challenging for you, even though you technically have the prerequisite under your belt. So unless you like biology and are up for the challenge, you shouldn’t force yourself through AP Bio just because you think it will look good on your transcript. In short, consider both your school’s mandatory prerequisites and your own broader preparation. Try and aim for classes you think you are very prepared for, especially if this is your first AP class! Since in an AP class, you will also have to learn how to study for a cumulative exam – in other words a single test that covers a year of material – you should make sure your first AP class is in a subject you do well in. Don’t underestimate the added challenge of the AP exam. #3: Consider Other Skills Certain AP Classes Will Require In this discussion about prerequisite courses, you might be wondering about AP courses like Human Geography, Economics, Computer Science, Psychology and Statistics, which often don’t have direct prerequisites. When considering those classes, think about the skills you have built up – because again, even if your school doesn’t have a prerequisite for those AP classes, you still shouldn’t walk in unprepared. Learning to code in Java for AP Computer Science will likely be a brand new experience, so you should come prepared with strong logic and problem-solving skills! For example, if you want to take Computer Science, Statistics, or Economics, a strong math background is important. Even though you won’t spend tons of time in those classes solving equations, the logic and skills you learn in math classes are necessary to take on CS or Economics. For Psychology, think about how well you do in science and social studies, and also consider how good you are at memorizing things, since you’ll have to master the structure of the brain. For Human Geography, consider how well you do in geography and history courses and whether you enjoy them. Also consider your ability to take a broad idea and apply it to a concrete case study – as an example, are you able to pick out patterns in historical events? This is a skill you will need for Human Geography. To learn more about individual AP courses and the material they cover, see the AP student website. As you read course descriptions, think about how they relate to other classes you have taken and the skills you have. #4: Learn What Specific AP Classes Are Like at Your High School You should also consider which classes are offered at your school and what their reputations are when choosing AP classes. For example, at my high school in Salt Lake City, AP BC Calculus was known as a challenging class with lots of homework. During the second semester, you had to take it for two class periods! In contrast, AP Physics was seen as laid-back, and students were expected to manage most of the studying on their own. Students who needed structure thrived in Calculus, while others who liked to work more independently did well in Physics. But the reverse was also true – some students got burned out by BC Calc, and others didn’t have the motivation to study for Physics and so even though they passed the class, they failed the AP test. That AP Physics class was also famous for building trebuchets and testing them out during school hours. In short, teachers approach AP courses differently. Some expect their students to manage their own studying, like in a real college course. Others make sure their students are prepared by assigning a ton of work. As you choose AP classes and learn about their reputations at your school, think about your own study habits and what kind of classroom environment will help you do your best. There are many other school-specific factors to consider: who teaches the AP classes? What are their pass rates? How hard are the classes themselves to pass? How many students take the class each year? These are questions you can take to your guidance counselor, the AP teachers themselves, teachers who teach the prerequisite classes, or even upperclassmen friends. (Though don’t rely just on student word-of-mouth, since it can be biased!) If your school is adding an AP class for the first time this year, think carefully before taking it – it’s always tough teaching a class for the first time, especially an AP class. There might be some growing pains that first year as the teacher works out the curriculum. Veteran AP teachers are often a safe bet, because they will have strategies for preparing students for the exam. Often they will be involved in AP grading as well, so they will have lots of insight into how to pass the test. #5: Think About How Busy You Are AP classes are big time commitments, especially in the spring (see our post on test dates for tips on dealing with the spring time test crunch). Some teachers require extra study sessions, including on the weekends, to give you time to take practice tests. So before signing up for a slew of AP classes, think about the other commitments you already have. Especially if you have a very time-consuming sport or extracurricular activity, taking more than two or three AP classes could overload your schedule. Even if you have friends who are taking several AP courses, don't feel like you have to keep up with them. Keep your own strengths and limitations in mind. It’s better to pass two exams than to fail four! If you’re not sure if you’ll have the time to take on an AP class, talk to your parents/guardians (or a guidance counselor or teacher if you have a good relationship) for advice. Also find out if you will be able to switch out of the course mid-year if you realize you don’t have enough time for it. #6: Think About Which APs Best Fit Your College and Career Goals AP Exams are a great way to begin exploring future college and career options. They are also a great way to signal on your college applications that you are considering what you want to study in college and are developing the skills for college classes. When I was in high school, I was positive I wanted to study political science or international relations in college. So in addition to activities like Debate and Model United Nations, I also took AP classes like Statistics, World History, US History, US Government, Human Geography, and Environmental Science. All of these courses helped me explore topics and issues that college political science courses tackle, and also gave me skills – from the ability to analyze a poll to being able to break down an article’s viewpoint and bias – that prepared me for political science. Remember to keep your end goal in mind! On my college applications, I was able to show my interest in political science with both my extracurricular activities and the advanced classes I was taking. In addition to my test scores and GPA, being able to show colleges I was serious about what I wanted to study helped me be successful during the application process. In short, think about your future goals and how your class choices now can support them. AP classes are a concrete way to demonstrate on your applications that you are serious about a certain major and have the skills to pursue it. To take another example, if you want to be a doctor, tackling AP Biology and AP Chemistry can give you a taste of what the pre-med major will be like, and you can get a sense of whether you would be up for it. It will also show college admissions officers that you are serious about pre-med. If you’re stuck between two AP choices that otherwise seem good (you’ve taken the prerequisites and they have good teachers), go with the one that you think will be more relevant to your major or future goals. Also keep in mind that taking an AP Language exam, if you’re ready, is a great way to show second language proficiency to colleges. Many colleges offer credit for AP language, so it can free up time for other classes. Summary: The Best AP Classes for You We've covered a lot of important factors in determining which AP courses are the best for you to take. You should first look to your strengths and prerequisites to see what you naturally have a good shot at doing well in. Then, you should look at your personal schedule and find out the reputation of AP classes at your school to figure out which classes you can handle, and which ones are out of reach. Finally, you should consider what kind of applicant you want to appear as to colleges. This will help you plan your coursework to support your goals. What’s Next?
