We started off by spreading it out on the ground. I should start by staying that even though this is a tent which sleeps 6 it comes neatly packed in almost a rucksack style bag – super compact and with wheels on one end so you can roll it, airport style, around. People scoffed slightly when we admitted we hadn’t yet given it a go…but Globalmouse is a busy travelling family and time rushed past us and before we knew it we were off…so when we got to the beautiful Somerset fields it was going to be make or break…humiliation or success!Īll around us families were putting up their tents in military formations – seasoned campers who each knew who had to stand where, and which pole needed to attach to which other pole…and on and on…it was a little intimidating!īut still, we were confident in our kit and out of the car it came. Of course we should have had a rehearsal of putting it up at home in the garden to test this out.

![]() ![]() It also allows students to focus on their weaknesses, plan their studies better, and more accurately judge how well they know the material. Research consistently finds that applying metacognitive strategies ingrains memories deeper into your knowledge, leading to better learning outcomes. Brainscape takes this further by asking you to assess how well you knew the answer to a question on a scale of 1 (not at all) to 5 (like the back of my hand!) When you reveal the answer side of a flashcard to assess your correctness, you are essentially asking yourself “How did my answer compare to this correct answer?” and “How well did I know (or not know) it?” This act of self-reflection is known as metacognition. The take-away: flashcards are effective because they make you pull information out of your memory (instead of just reading or recognizing it), and this helps you build memories quicker and perform much better on tests. Some research has found that this kind of active recall retrieval practice leads to 150% better retention than passive studying. And because flashcards can so easily facilitate repetition, they are the best way to create multiple memory-enhancing recall events. In other words, you are attempting to remember the concept from scratch rather than simply staring at the passage in your textbook or recognizing it on a multiple choice quiz (and we all know that multiple-choice quizzes suck for studying).Īctive recall has been shown to create stronger neuron connections for that memory trace. When you look at the front "question" side of a flashcard and think of the answer, you are engaging a mental faculty known as active recall. The benefits of flashcards Brainscape flashcards are effective because they leverage the learning power of active recall, metacognition, and spaced repetition. Here are the top 3 reasons why flashcards are so effective. ![]() And there are good scientific reasons for this. You may think flashcards are for kids but there’s a reason they've been a preferred study method for hundreds of years: They friggin’ work! In fact, flashcards are hands-down the most effective way for motivated learners to study and retain factual knowledge, especially when the flashcards are used properly. You see your classmates carefully color coding their biology flashcards and you wonder: Are flashcards effective?

Yeesha, who is also known as the Grower, wants to restore the D'ni civilization through the use of 4 magical Slates that lock in a powerful Tablet. Atrus wants to see the ancient D'ni civilization rebuilt to its former glory. His wife Catherine is dead, as are his two sons Sirrus and Achenar. Myst V: End of Ages takes place over 200 years since the events of Myst. For many fans, it is a fitting end that the creators themselves are able to give a pleasant and satisfying closure to perhaps the most iconic game series in the history of the adventure genre. In 2005, the Miller brothers finally returned to release the last installment of the series, under their studio now renamed Cyan Worlds. The series then undertook a long hiatus, until the release of Myst III: Exile in 2001 and Myst IV Revelation in 2004 by Presto Studios and Ubisoft respectively. The series was created by Rand and Robyn Miller, who cofounded Cyan (later called Cyan Productions) under which Myst and Riven: The Sequel to Myst were released in 19 respectively. Myst V: End of Ages is the fifth and presumably final game in the highly acclaimed Myst series.

WebFor decades, Body Mass Index (BMI) weight in kilograms divided by the. In a study published in the Journal of Economics in 2008, John Cawley, professor at Cornell University, was able to demonstrate that, relative to percent body fat, BMI appears to misclassify substantial fractions of individuals as obese or non-obese. The Body Mass Index (BMI) Calculator can be used to calculate BMI value and corresponding weight status while taking age into consideration. There are many formulas for calculating ideal weight not all of them work. So, although they may seem to have a weight within the normal BMI range, their measurement actually needs to be scaled-down to reflect this. Similarly, as people age their bone density decreases. For example, professional athletes are often considered overweight or obese when using BMI measurements due to their muscle content, which weighs more than fat. Measuring Body Mass Index Health professionals commonly measure Body Mass Index (BMI) to assess whether patients are a healthy weight. BMI provides a reasonable estimate of body fat for most people. A high BMI is associated with an increased risk of chronic diseases such as heart disease, high blood pressure, and type 2 diabetes. BMI uses weight and height to estimate body fat.

The Gulfmaster GN-1000 is a more affordable battery-powered model with a Twin Sensor (compass and thermometer) and tide and moon data. Like the GWN-1000 it has a tide graph and the moon age data is available on the LCD display. Other new features include sunrise/sunset data, a sapphire crystal. The Gulfmaster GWN-Q1000 is the latest Gulfmaster model and the first G-Shock with a Quad Sensor which includes a water depth meter, altimeter, barometer, compass, and thermometer. The GWN-1000 does not have a dedicated moon phase graph like the other watches on this list but it does display the moon age as a numerical value on the LCD display. The Gulfmaster GWN-1000 is G-Shock’s flagship maritime model featuring a Triple Sensor (altimeter/barometer, compass, and thermometer) as well as a tide graph and moon age data. Its dark reverse display gives it an extra-tough look though some may find it more difficult to view than a standard LCD display. The GW-7900B-1 has Tough Solar and Multi-Band 6. The tide graph and moon chart make this series a good choice for coast guard personnel and boaters. The large case and buttons allow the watch to be operated with gloves.

The smaller size of the GLX-5600 also makes it a good choice for anyone who wants a tide watch that is as unobtrusive as possible. The tide and moon data will help surfers determine when the waves will be at their peak. The GLX-5600 has a low profile of 12.7 mm which is considered very slim for a G-Shock. Housed in the popular GA-100-style large case, the GAX-100 is an analog-digital model with a tide chart and moon graph and also a thermometer sensor. ![]() The GAX-100 series is a recent addition to the G-LIDE line. The G-Shock G-LIDE series is designed for action sports and the following models are part of its designated surfing line. It brings to mind the G-Shock lineup of the 2000s when G-Shock watches were still medium-sized and mostly digital-display models. The Gulfman is a straightforward model that would serve one well on the job. That combined with its tide and moon phase graphs make it a good choice for seafaring use. The Gulfman G-9100 is known as the “Rust Resist” G-Shock with its external metal parts made of a titanium alloy. Here are all the Casio G-Shock watches available featuring tide and moon data for all your beach and ocean needs. While a tide watch is not meant to be the only resource for proper trip planning, it is a convenient way to have quick access to ocean conditions as it can give you the tide level and moon age for the current time as well as at a specific date and time in the future. A G-Shock watch with a tide graph and moon chart is a useful tool for a variety of outdoor activities such as surfing, fishing, boating, kayaking, and beach combing. First, the volume must be converted from milliliters to liters. Let’s start with these values:įollowing the same process outlined above, we can determine the concentration of this calcium chloride solution in a few simple steps. Using a different compound, calcium chloride, we can calculate the molarity of a solution in the same way. This means that every liter of this solution contains of ammonia. If we take the two values from the previous step, we see that the ammonia solution is. ![]() The third and final step is to use the molarity formula and divide the number of moles of solute by the number liters of the solution to obtain the concentration in moles per liter. If we say that the solute is of ammonia (NH 3), we can convert this to moles using ammonia’s molar mass ( ): If the known amount of solute is in grams, it must be converted to moles using molar mass. The second step is to determine the amount of solute present in the solution in moles. For example, if the volume of the solution is : So, with a simple calculation, any volume in milliliters can be converted to liters. If the starting volume is in milliliters, it must be converted to liters before calculating concentration. For molarity, volume must be in the unit of liters. The volume of the solution can be measured by using a graduated cylinder. First, we will start with volume in this tutorial. The first step to calculating molarity is identifying one of the two key factors that make up the solution: the volume of the solution and the amount of solute in grams or moles. The periodic table provides the atomic masses that are used to calculate molar mass. In the case that moles of the compound are unknown, molar mass can be used to convert the compound from grams to moles. Molarity is calculated, using the formula above, by considering two components: volume and moles. The formula for calculating molarity, the molarity equation, is When you see “ “, you read that aloud as a “1 molar solution”. Also, don’t confuse molarity with molality, which is slightly different! It is important to know, that the volume of solution is measured after the solute is dissolved, not before. If you dissolve 58.44 grams of NaCl in one liter of water, you have a one molar solution, abbreviated as. One mole of sodium chloride weighs 58.44 grams. For example, if you dissolve table salt in water, salt is the solute, and water is the solution. Molarity is the number of moles of solute per liter of solution. This is what makes up the majority of the solution, which is usually water or in some cases, an organic solvent. ![]()
