Top 10 Temperature Calibration Tips

There's a common belief that temperature calibration isn't possible in digital devices. It is a sane belief but still, there's a working logic for this operation. When you enter a desired value to calibrate the device, the internal temperature of the thermistor is manipulated accordingly. This is exactly how it works. Following are top 10 tips on temperature calibration.

1. Select the best thermistor

The Platinum Resistance Thermometer is the most accurate thermistor known to the developers at present. The readings are accurate up to a few decimal places if measured digitally. If you aren't familiar with transducers, then you can go with the analog display. The readings on the scales are accurate too.

2. Avoid usage of fluid chemicals

Try to stick to the dry-well; as the name suggests, it is dry and almost 0% moisture is present. Calibration bath is physically unpleasant as it contains viscous fluids. A dry-well is an excellent way to deal with messy fluids.

3. Keep an extra thermometer

It is recommended that you carry two or more thermometers to minimize the reading errors. Read a number of thermal devices at once and tally the readings. If the readings differ a little, consider the average.

4. Use a thermal source

While calibrating the device, make use of an external thermal source to provide heat to the device.For instance, if you wish to reduce the temperature by two degrees; then make contact of an external source to reduce the temperature by two degrees. Similarly, operate the thermal device to increase the heat. The thermal source must be digital and should be accurate up to at least two decimal places. Digital devices are always convenient.

Attend Cna Classes For Free

For some people, the cost of attending CNA classes can prevent them from following the career path that they want. The cost of classes is perceived to be an obstacle and for some they dismiss the idea of becoming a CNA because in order to earn money from being a CNA, first of all you need to pay for the relevant training. I would argue that your CNA training should be considered an 'investment', though I am aware that some people simply aren't willing to part with their money with no guarantees.

So, where do you find free CNA courses?

What I consider to be the best idea is to enquire at local healthcare providers in your area - this is basically hospitals, care homes and the like. You're looking for places that need CNAs - of which there are many. There's a general consensus that there is not enough CNAs currently and this means these organisations are desperate to help any aspiring CNA to fulfil their ambition. These organisations are often will to pay for you to attend CNA classes, though often in return you have to commit to working for the organisation for a specified number of months.

Other avenues you can explore are should you are aged 16-24, and have no income, you can receive CNA training through Jopb Corp at 1800 733 JOBS. It is also worthy of note that if you are disabled then you qualify for this irrespective of you age.

Introduction To Teaching Methods

Teaching English as a second or foreign language entails the use of both traditional teaching methods as well as instructional techniques that are unique to the study and learning of language. Traditional teaching methods include teacher-centric approaches such as explicit teaching as well as approaches that encourage active student participation. Based on the teaching experiences of educators around the world, different techniques should be deployed depending on the instructional purpose, the subject matter, and the students' level of competency, cognitive ability and enthusiasm. Concentrating and using just one approach has often been found to be grossly inadequate while a rich combination of approaches result to the most favorable learning outcomes.

This article describes the most common and effective methods that are being used in traditional classrooms as well as the alternative or improvised techniques that have been developed specifically for language instruction.

Fundamental Methods of Instruction
The primary approach in sharing new knowledge is basically the teacher-centric model that entails the techniques of 1) Exposition/Explanation/Description, and 2) Demonstration. Meantime, the participatory approach balances the responsibility of the cognitive process between teachers and students and employ the techniques of 1) Collaboration and 2) Teaching from a student perspective.

In the teacher-centric approach, the learning process follows the classic knowledge transfer model: teacher-to-student. The basic techniques used in this model include direct exposition and explanation of different subjects through formal or mini lectures that may be accompanied by audiovisual materials (whiteboard notes, CD ROM, videos, music, presentations, and other instructional multimedia). Using the techniques of exposition-explanation-description, students are often required to memorize different concepts, and, in the case of language instruction, the actual verbalizations (oral recitation) of words and phrases.

Top 10 Online Public Service Degrees

Earning an Online Degree

Many careers in public service require a bachelor's or higher degree, and even professionals in occupations that do not require a college education should consider the many benefits of attaining their higher education. Most persons interested in public service careers will benefit considerably from additional education. Although the cost of education is skyrocketing - including living costs and school supplies on top of tuition - online options are making it more feasible for working professionals to pursue their higher education with lower costs and more flexible learning.

Earning an Advanced Degree - Return On Investment (ROI)

Average worker salaries increase with education, and unemployment rates decrease. According to the U.S. Bureau of the Census, in 2007 the median annual income of individuals holding a master's degree was $52,390 to $9,247 higher than for individuals with a bachelor's degree. In most cases, a person who earned a master's degree would recover the cost of the degree through increased earnings in less than a decade after graduation. Adults with advanced degrees earned four times more than those with less than a high school diploma. In 2006, workers 18 and older with a master's, professional or doctoral degree earned an average of $82,320, while those with less than a high school diploma earned $20,873. In 2012, the average increase in salary between those with an associate's degree and those with a bachelor's was by 74 percent, while the average increase for those with a bachelor's to those with a graduate degree was by 64 percent.

Top 10 Degrees for Public Service Professionals

1. Bachelor's in Fire Science
Online degrees in fire science provide strong foundations in technical aspects of fires and hazardous materials and emphasize professional skills, ethics, service, and leadership. While most firefighters have a high school diploma, workers with an associate's or bachelor's degree in fire science are often preferred, and an associate's degree is required for executive fire officer certification from the National Fire Academy. Some departments offer incentives such as tuition reimbursement or higher pay for advanced degrees or training. Online bachelor's or master's degrees in fire science (or related fields such as public administration) can also help firefighters move up the career ladder - helping them reach higher positions in their field, such as fire captain, chief or investigator.

Renewable Energy And The Green Economy

The renewable energy industry is on the verge of creating a worldwide economic boom. Venture capitalists around the world are poised to invest heavily which will create new jobs at a remarkable rate. In other words the green economy is the next big economic boom. Governments that recognize this trend are investing heavily in educating their young people to be ready for the new economy that will define their lives. Technology companies are wanting college graduates with expertise in the new tools, methods and techniques.

In the UK alone, fuel consumption is expected to increase in 2014 to 770 quadrillion thermal units. That is an astounding 50% increase over the 2012 figures. Global consumption of fossil fuels is increasing at an unbelievable rate. New oil platforms are being built in dangerous waters with the potential for economic and environmental disaster. As these sources are depleted, alternative fuels are a necessity. Globally, consumers are beginning to expect the fuel sources to be clean as well as affordable. Depletion of fossil fuels, changes in the environment, and improved technologies are driving the creation and expansion of the green economy.

Worldwide there are approximately 2.7 million people employed in all phases of the green economy. The green economy, as it is now being called, is labor intensive and is defining how people will live, work and play in the 21st century. Everything including construction, manufacture, distribution, sales, maintenance and every other aspect of human life is changing. Instead of burning coal for electricity, nature will manufacture the power we use via the solar panels and wind turbines. The use of renewable energy will raise the standard of living worldwide. The investment is necessary, and every country, rich or poor, will eventually have to embrace the new reality that renewable energy is the only power source available.

The Good Side Of Homeschooling Your Kids

Homeschooling as the terms connotes is an educational methodology wherein a child is taught by a parent or a tutor at home. Home schooling is more popular in urbanized countries as another option over private and public schools.

In the traditional processes, children are taught at school. Home school education on the other hand, gives emphasis on self - paced education and independent learning strategies. Certainly, by adapting this approach, parents are eased that their child are given the best education there is.
In order to supplement teaching, most parents and tutors make use of home school materials and resources. Without this, the entire experience will eventually fail. Educators can either create their own curriculum program or download pre - planned curriculum online. Starters are recommended to buy completely written curriculum, lesson plans or study guides until the lessons are mastered and got used to home school teaching.

Most definitely, home school education will require educators to exert effort and dedicate more time in teaching their home schooled child. The parent (as the teacher) should foster good relationship to the child (as the student) and entail motivation and perseverance throughout the whole course. Proper assessment must be carried out in order to tell the productivity of the child. Self - assessment is also important in order to improve the teaching strategies of the educator.

Home schooling appears to be difficult but rewarding at the same time. It develops family interaction and the family's closeness is practiced. Another benefit of home schooling your child is it prevents untoward incidents like violence and school related accidents.

9 Approaches Towards The Best Science Fair Project

Setting up a fabulous project can feel scary initially and yet, as with most stuff that will seem to be overwhelming, if you decide to break the problem down into simple steps you could achieve almost everything. Frequently any project is simply separated into several parts:
A - Get to know your subject.
B - Design and build a display.
C - Deliver a presentation on the subject in addition to the exhibit.

Listed here are the most important 9 simple steps to your successful science fair project

Get to know your subject

1 - Look for a subject which can interest you - Get a fun subject which seems like it might be cool to learn and you should not be particularly frightened of a challenge. The assignment is unquestionably created through taking it just one action at a time. Plus a challenging project typically leads to a more desirable grade.

2 - Prepare a project plan - When you finish determining precisely what subject you would like to exhibit, decide what it really could be that you'd like to demonstrate. This type of project plan is normally just for your use. It's usually broken down straight into discussing areas relating to the particular material and has an introduction, detailed description or simpe demonstration, as well as a summary. This plan ought to do several things:

- It can help you comprehend the topic much better,
- It can help you foresee most of the unavoidable problems that will come up,
- It can be used for a resource whenever talking about the subject and even writing a written report.

3 - Research your subject - Just like any report, and a science fair project is just a more sophisticated report, all the hours you actually put in finding out about the topic will pay off over time. However the time devoted investigating should be used on actual research. It is really quite easy to become derailed when performing research. Here is where the project plan come in, stick to the plan and set targets to know each section of the project plan one step at a time.

Design and build a display

A display often is the center point to your assignment. It will be where nearly everybody will likely be centering their attention. It is intended to not just demonstrate your expertise of the subject matter, but it will certainly explain the topic to individuals who will not know much about the topic.

Galileo Galilei Biography

One of the most well known and influential individuals in the scientific realm to ever live goes by the name of Galileo Galilei. Many have heard of him, but few actually have a detailed knowledge of his life and accomplishments.

Most consider this man to be one of the most important scientists in history. Many aspects of his life have taken on epic proportions. The contributions he made to the world of science are still revered to this day. He would go on to play a major role in the scientific revolution.

Born in Pisa, Italy on February 15, 1564, he was the son of a famous lutenist and musical theorist. A deeply religious individual, he spent his life as a devout Catholic. After considering a career in the priesthood, he eventually enrolled at the University of Pisa at his father's urging.

Originally enrolling to study medicine Galileo soon decided to pursue mathematics instead. This decision would impact the world of science. Many of the most prominent scientists of our time cite his work involving natural sciences and the scientific method as some of the most important of all time.

Most are familiar with his role involving the Catholic Church. His support of the heliocentric theory that the Earth revolves around the sun was thought to contradict scripture. He was put on trial for his views. Many of his work and teaching were banned and he was put under house arrest. This incident has taken on somewhat legendary proportions, though most are misinformed of the events, as they are surrounded by myth and legend.

5 Useful English Expressions

Idioms refer to phrases where their common meaning cannot be understood simply from the meanings of the individual words. They are cultural elements of speech and can prove a barrier to those who are speaking a non-native language. Five common English idioms are given below, together with their meanings, origins, and examples of their use in everyday use.

1) Step up to the plate
The origin of this phrase was in the American sport of baseball. A batting player must step towards the “home plate” in order to be ready to strike the ball. Its common use is to refer to a) the taking on of responsibility generally and b) acknowledging responsibility that already exists.

Example of a) “Since you have been ill lately I suppose I will step up to the plate and take on tomorrow’s presentation”
Example of b) “Stop being so lazy, you need to step up to the plate and provide for your family!”

2) Doubting Thomas
This phrase is a biblical reference. One of the twelve Apostles of Jesus, Thomas, did not believe that Jesus had risen from the dead until Jesus appeared before him. The phrase is commonly used to refer to sceptics and those who make a habit of requiring proof for any statement.
Example: “John is such a doubting Thomas, if you said it was raining outside he would want to see your umbrella and if you said it was cold he would check a thermometer.”

3) A Baker’s Dozen
This phrase comes from the tradition that bakers had of when they were serving a dozen (i.e. twelve) baked goods to a customer, adding in one extra so that there could be no accusations that the goods were underweight. Nowadays it is used simply to refer to any group of thirteen items.
Example: “My parents had many more children than is usual. There is a baker’s dozen of us all together.”

Online Resources For Online Learning Support

With the emergence of the digital age comes expanding opportunities for businesses to offer educational opportunities to their employees that will further their success in their careers. These days, you aren't only limited to relying on textbooks for learning. You are able branch out in different and innovative ways to aid in educational experiences. The prevalence of online education is booming and many individuals and companies are taking notice of the benefits this type of education can bring to their employees and, ultimately, their companies.

Supplying one's employees with the latest skills and knowledge so they are able to perform in their job role confidently and efficiently is a huge benefit for any business, regardless of their demographics or what type of business it is. To earn from online is a great tool to aid in bettering businesses of all kinds and it comes in many forms. With this, there is bound to be a learning strategy that works well for nearly all types of individual learning styles.

Some people may prefer online tutorials, or lectures, led by an instructor while others may prefer a self-study type of experience where they can read content online at their own pace. Some individuals prefer an interactive, hands-on online learning experience and for these people there are tools available including formal learning forums, chat capabilities, live labs and video conferencing. For the on-the-go learner, there are exciting mobile e-learning options as well. Many e-learning providers are now enabling integration of mobile devices such as iPads which makes education resources extremely convenient to access.

Classroom Management Techniques

In addition to being highly knowledgeable in the subject matter, teachers also need to know how to manage classroom dynamics effectively. This entails organizational and disciplinary skills that both help make different types of classroom interactions more systematic and aligned with the learning objectives. Otherwise, classes that are conducted by teachers with very minimal classroom management skills tend to produce less favorable outcomes, such as low student achievements. Some studies, in fact, suggest that when teachers are inefficient at managing disruptive classroom behavior, the average pace of cognitive development among all students suffer greatly.

If you are a native English speaker who intend to teach English as a second or foreign language (ESL/EFL), it will be well to note that the paired factors of 1) disruptive behavior of students, and 2) inability of teachers to effectively manage classroom behavior, jointly cause an alarming number of new educators to leave the teaching profession. This means that in addition to generating mediocre results in terms of the learning goals for students, ineffective classroom management also cause stress, deep resentment and burnout among many teachers, to the point of compelling some of them to consider another profession. In second or foreign language learning, the cultural and linguistic gaps among students and teachers can also aggravate the learning conditions in many ways.

That said, the underlying principle should be obvious: teachers need to develop classroom management skills in order to attain positive learning outcomes. While it is true that managing student behavior is not an absolute guarantee to success, well-managed classroom behavior is a requirement for establishing an environment that is conducive to learning. After all, learning takes place most positively when students are properly motivated to learn.

Given this teaching scenario, don't lose heart nonetheless. Disruptive behavior is a normal occurrence in the learning process such that veteran educators have established different methodologies and techniques in order to quell learning disruptions. In addition, the demand for English language educators are in the uptrend globally simply because there is a real need to learn the lingua franca of globalization among non-native speakers. Behavior among learners also varies, depending on many factors such as location, economic segmentation, and the motivation to learn. While there is a real linguistic and cultural gap between teachers and students, such differences have been used by enterprising educators as positive inputs for learning.

Good Writing Is Like A Diamond

A few months ago, after my friends at EzinesArticles.com awarded me their Diamond Expert Author status, I just naturally took a much greater interest in diamonds. By doing some diamond research I was able to learn many interesting facts about them and how their facets can be compared to what we considered to be top quality writing.

For example:

Gemstones commonly have facets cut into them in order to improve their appearance by allowing them to reflect more light.

Those facets are the flat geometrically shaped surfaces you see on every diamond. Historically, the organization of naturally occurring facets was key to early developments in crystallography, since those facets reflect the underlying symmetry of the crystal structure.

As you know, much of the beauty of a diamond lies in the way those many, many carefully prepared facets reflect and enhance light. In the same way, a skillful author can add fact after fact in his article to help his readers see clearly how those facts can give them the knowledge they need to understand completely the point of view of the author.

For our purpose here, perhaps we can re-write that definition of diamonds in a new way and relate it to what we consider good writing:

Facts, in a piece of writing, are much like the facets of a diamond gemstone because they reflect the crystal clear thinking of the author. A good writer knows that facts are the keys to clear writing that can produce an underlying symmetry of understanding in the minds of his readers. Therefore, the more facts, the better the writing.
