How to Calculate Heat Loss

How to Calculate Heat LossWhen I was in college, I read a couple of books on how to calculate heat loss, but I don't recall which one it was. I guess I just got a book from the library or something. It was some sort of long-winded one and it was full of formulas and equations and all kinds of figures.It was an interesting and difficult thing to figure out. But that's how I learned how to calculate heat loss. I'm sure there are others out there who are still figuring it out.Now I know how to calculate heat loss because I have studied science for many years. But for some reason, for some reason it's much easier to understand heat loss in mechanical terms. That's probably why so many people don't understand it. And I don't blame them at all.In a mechanical term, it's fairly easy to understand, isn't it? Heat is a mass moving through a medium. The first step is to convert heat into mechanical energy by converting heat to work. In a mechanical term, all we have to do is think of heat as a material through which a force can be applied.Let's say you're standing at a very high temperature. You push your hand up to the surface and the material in your hand expands. The energy that was in your hand gets converted into work and you can feel the heat. That's what happens when you put an object in a liquid or a gas and make it expand.When you've got a substance in a low temperature, like air, it won't expand no matter how hard you try. It will, however, contract. It'll become cooler because it's not absorbing any energy.You've just experienced heat transfer, meaning you've taken heat from a source to a heat sink. If you put the same object in a highly viscous fluid, it would absorb a lot of heat and be less than a bit warm. In a similar way, a hot object moves through a medium faster and can transfer a lot of heat, especially at very high temperatures. All it takes is to know how.

4 Ways Social Media Can Benefit Your Students Learning Experience

4 Ways Social Media Can Benefit Your Student's Learning Experience Most of us engage with social media informally, or at least associate social media with our non-academic lives. Often, though, we dont realize how much social media is a part of the way that we learn about and see the world. Social media can, in fact, benefit your students learning experience in many ways, including offering unique resources, building learning communities, and providing real-world examples and experiences. Looking for ways to enhance your students education this semester? Keep reading to learn four ways social media can benefit your students learning experience. 1. Social media can provide unique learning resources for your student The internet is known for providing excellent resources for projects. Whether your student needs help with a research task, an essay, or another kind of project, seek out social media networks in addition to the librarys in-person and online databases. Twitter, for example, is a social media platform that can feel like a jumble of unorganized information. However, it provides access to an abundance of linked resources. Use Twitter to search for a hashtag of your topic to bring up a list of results. If youre looking for visual content, YouTube is one resource that offers tutorials and short teaching videos, in addition to educational channels. Check out YouTube alternatives, like TeacherTube, if youd like a more focused, kid-friendly search. [RELATED: A Parents Guide to Learning in the Digital Age] 2. Social media can help your child organize resources in one place Social media platforms are also great ways to organize resources into one place that you can later come back to. This is especially helpful for larger projectsyou can bookmark resources into one large folder, or you could create smaller folders within a larger one according to your organizational needs. Pinterest works great for this as a visual bookmarking platform. The great thing about this platform is that you can share individual resources or the entire folder with classmates, so students can collaborate together on projects or help each other with study resources. 3. Social media can build learning communities Social media is an excellent way to build and join a learning community. Some schools have social media platforms that they use within the classroom, where teachers can: Send announcements Provide links and resources Facilitate online discussions If youd like, you can also search for your own learning community on larger platforms, like a specific group on Facebook. A lot of times, these learning communities provide forums to ask and have questions answered online. These platforms offer an engaging give-and-take where your child can contribute to the greater educational community. [RELATED: 3 Emerging EdTech Tools That Can Spark an Interest in Learning] 4. Social media can offer real-world examples and experience Communication has become increasingly digital in recent years, and social media is an excellent way to engage in ongoing discourse. While your child should not feel forced to join a specific social media network, if theyd like to, encourage them to see how they can apply classroom skills they already use or are excited about. Encourage them to engage in topics they care aboutfinding people to follow on Twitter or Instagram, for example, that support an expansion of their interests. Encourage them to consider audience, and how they might be able to share their interests with a wider online group. [RELATED: 5 Benefits of Using Videos to Learn] Be sure to speak with your student about online safety and strategies that can help make social media usage a positive and enriching experience. Dont shy away from topics like cyberbullying and trolling. Opening conversations about the good, the bad, and the ugly of social media will help you give your child the necessary skills to take advantage of the best parts of these platforms.

English Vocabulary related to Driving - Intermediate Level English

English Vocabulary related to Driving - Intermediate Level English Driving a car can be one of the great pleasures in the world. Driving a manual car  (car with gear stick and not automatic)  whilst requiring more hand and foot action is a better experience. Here are some English verbs that we use when describing or explaining how we drive a car. I have also included some idiomatic expressions connected with driving.  So by the time you get to the end of this post, you will learn useful English vocabulary related to driving. English Vocabulary Related to Driving I am sure you can all remember the first time you got into a car. The very first time your father allowed you to drive HIS car. I certainly do although it was many years ago. Firstly make yourself comfortable put on your seatbelt  (click it in place)  and you are ready to go.Start the engine  (switch it on or turn it on), check in  (look in)  the mirror to see if anything is behind you (coming form behind you),  release the handbrake  (turn off a device operated by hand that prevents a vehicle from moving), then indicate  (switch on the indicator)  press the accelerator a little and pull out  (move out)  into the lane and off you go! Simple.Well, yes and no. If it is your first experience then your mother or worse still your father will be telling you “take it easy, drive carefully, watch out for this and that, slow down etc”.   A nightmare. Better to go to a driving instructor and protect your family relationships. English Vocabulary about Driving - Infographic Enjoyed this infographic? Here’s what you can do next: Once you are on the open road or driving in traffic  (many cars)  then the instructions will be coming thick and fast  (a lot of them). Don’t drive to close to the car in front. Don’t exceed (don’t go over)  the speed limit. Watch out for (keep an eye on)  the road signs.  Do not overtake  (go past)  any cars yet until you are more experienced. When you are approaching  (coming close to)  the traffic lights  slow down  (reduce your speed)  put your foot gently on the brake. Change gear. Go from 4th  or 5th  gear to 3rd  then 2nd  and apply the handbrake when you come to a halt  (stop) at the traffic lights. When the lights turn green (your signal to move forward)  move slowly by pressing the accelerator and changing gears smoothly. Go up the gears  (from 1st  to 2nd  and so on)  and increase your speed accordingly.When driving at night you have to be more aware and watch all around you. You must of course switch on the headlights and drive with  dipped  (low) headlights to avo id blinding cars coming towards you  (in the opposite direction). Normally we reduce our speed when driving at night .If you have to  reverse  (go backwards)  make sure you check  (look in)  your rear view mirror  (shows you what is behind you)  and reverse slowly.As your driving improves you should learn the skills necessary to handle the car in wet or icy conditions. You will learn how to handle the car if it  skids  (goes out of control on a wet or slippery surface)  how to swerve  (control and steer)  the car safely to avoid something blocking the road and how to apply the brakes suddenly if you have to make an emergency stop  (to pull up suddenly). English Idioms about Driving There are many idiomatic expressions associated with driving. Here are some :A BACK SEAT DRIVERAlways try to avoid being one of these. When you are used to driving and you are getting a lift as a passenger with a friend or family member avoid the temptation to tell them what to do and what not to do.ex. David was getting a lift to the airport from his wife. She was dropping him off (taking him there) on her way to work.   Mind that car, slow down here, watch that guy on your left Oh David stop I don’t need a back seat driver!A SUNDAY DRIVER    You are driving with the family going to a picnic on a sunny Sunday afternoon. The traffic is quite light but there is someone driving in front of you who is driving very slowly and admiring the view. Your only wish is that he would pull over and let you go past him (overtake). These Sunday drivers would drive you mad!!A ROAD HOGThis is even worse than a Sunday driver. The guy is driving reasonably fast but his car is not as powerful as your car but he does not want to let you go past. He drives in the middle of the lane or worse still between two lanes and you cannot get past him. Road hogs usually think they own the road.ex. Road Hog, hy is he hogging all the road! (why does he want all the road!)HONK THE HORNNothing annoys me more than to be sitting in my car at the traffic lights waiting for the lights to turn green and the car immediately behind you honks on the horn  (beeps on the horn)  impatiently the split second  (just before)  the lights turn green.TO BE IN THE DRIVING SEATNot necessarily connected with driving. This expression is used to describe someone who finds himself in control of a situation in business or in his/her private life.ex. Margaret couldn’t wait to get to work on Tuesday. The events of Monday meant that she was now in charge of the project and the team knew who was in control. She had got what she wanted. She was very firmly  (definitely)  in the driving seat and she loved it.SITTING ON Y OUR TAILAnother pet hate  (something I really do not like)  of mine. You are driving  along without a care in the world and some idiot behind you decides you are not going quickly enough so he sits on your tail  (literally gets very close to the back of your car).  This is both rude and dangerous as an accident is certainly unavoidable if you have to apply the brakes quickly  (stop quickly) I usually put on my hazard lights as a gentle warning and if that does not work then I start slowing down until he/she gets the message  (understands what I mean).Happy driving!

The First Report Card Solving Math Struggles Early

The First Report Card Solving Math Struggles Early The First Report Card: Solving Math Struggles Early Its report card season, which means by now your child has likely received or will soon receive his or her first report card of the year. Though only an initial assessment of a students achievement in class, the first report card can serve as a crucial tool for parents, as they can help identify weaknesses in a students skills and abilities. When this is the case, its time to initiate a plan to provide your student the extra help he or she will need for a more successful school year. When reviewing your childs report card this fall, pay particular attention to his or her grades in math. Many students in the United States struggle with math; in fact, yearly polls reveal that math is the subject students say they find most challenging. Yet, adequate math skills remain essential building blocks for math and science courses throughout high school and into college, and are even critical in daily life. Because math is a sequential subject and depends upon the gradual accumulation of concepts and skills, when a student falls behind, its particularly difficult to catch up. Theres simply no way to progress to algebra without a strong foundation in multiplication and division. Whats more, this subject also depends on patience, practice and abstract thinking, and its concepts can be difficult for students to connect to the real world. Its therefore easy to see why so many students face frustration, discouragement and the possibility of failure when they fall behind in math. The key to success in math for the remainder of the school year and beyond lies in addressing issues the moment they arise, and taking appropriate action. Consider the following when determining if your student needs help in math: Interpret their report card. While a grade gives a general idea of whether or not a student needs help in math, its important to interpret the grade in the context of how you know your student has performed in the past. Has your straight A student suddenly earned a B+ in Algebra II? A B+ is a good grade by any measure, but for your student, it could be the first sign that extra support is needed. Assess changes in your students attitude towards math. If you sense your student is less excited about math than he or she was previously, or if it takes more encouragement than usual to get your student to complete homework assignments, your student may be struggling to stay afloat. Consult your students math teacher. This can be particularly helpful if youre having trouble determining if your students report card reflects the need for additional help. For example, for a student with a history of average performance, it may be difficult to know if that C in math on his or her first report card is a sign of future failure; discussion with a teacher can shed light on whether the cause of a grade is truly lack of comprehension or other factors, like a failure to regularly turn in assignments. Once youve determined your student needs help, create a plan that involves a math tutoring service. Structured, individualized tutoring that targets key skills can not only elevate a students grade, but improve his or her overall comprehension and confidence with the subject. Math tutoring is the best course of action for a student struggling in math because it offers the key components for success likely absent from an at-home study plan: clear objectives, accountability, a professional instructor, and structured lessons. Theres no question that with a subject as essential as math, your student deserves the benefit of personalized math tutoring. The Huntington Learning Center offers math tutoring programs that focus on key math skills for elementary school, middle school and high school students. With our academic evaluation of your students skills and weaknesses, the Huntington Learning Center provides individualized, goal-oriented tutoring that can strengthen skills and raise grades.
