Gas is important

Sunday, April 26th, 2009

In todays modern economy, Gas & Oil, have become such important aspects, that it would be safe to say that we rely on them. A few examples are gas in our cars, for our furnaces, and the production of plastics. How much do you really know about Gas though?

A gas is one of the different phases of matter. Similar to liquids and plasmas, gases are fluids. This means that they have the ability to flow and that they will not usually return to their prior stage after they have been deformed. This doesn’t mean that they don’t have viscosity. A property of a gas that is different from that of a liquid is that; a gas does not occupy a fixed space or volume, but will instead expand to fill whatever container it is in, this is opposite of a liquid that will remain the same.

After Plasma, gas has the second highest energy per molecule. Due to this extreme amount of kinetic energy, gas atoms and molecules of gas will usually bounce off any container they are placed in, and even off of eachother. This bouncing will occur with more power as the kinetic energy of the gas is increased. Many people, incorrectly believe that when these molecules collide provide the main basis in explaining gas pressure. This is not true because the random velocities of the gas are enough to define the gas pressure. Not to leave these collisions in the dark, as they are very important in establishing the Maxwell-Boltzmann distribution of the gas.

It’s interesting how we use the word “gas” every single day, and all that we relate it to is the rising gas prices, or something that we get when we eat too many beans. There is alot more to gas then that, and is an important part of our everyday lives.

Diamond Grading Reports

Thursday, April 23rd, 2009

You’ve been told that having a certificate or
a diamond grading report is important, and
as a responsible consumer, you get one –
unfortunately, you probably won’t understand
a word of what is on that diamond grading
report, unless you are a jeweler.

On the color grading scale, D, E, and F
mean that the diamond has no color. G, H,
and I means that it has very little color. J, K,
and L means that the diamond has a slight
yellow color. P, Q, R, S, T, U, V, W, and X
means that the diamond is a darker shade
of yellow. Z means that the diamond has a
fancy color – other than white or yellow.
On the color grading scale, D is the most
valuable, and X is the least valuable –
however diamonds that get a Z rating are
the rarest and most expensive diamonds
in the world.

There are many aspects to a grading report.
Figuring it all out can be very confusing. You
should talk to a jeweler you trust, and have
them explain everything on the diamond
grading report to you.

Learning how to Operate a Motorcycle

Monday, April 20th, 2009


The idea of riding a motorcycle is to allow you the freedom of the open air while traveling. It can also be a very inexpensive way to travel or to commute. Learning how to operate a motorcycle is very important. You don’t want to be an inexperienced operator out there with so many other vehicles on the road. The process is quick for some, and others struggle to learn how to operate one. It comes down to learning the skills and believing in your ability to make it happen.

Keep in mind that the motorcycle you learn on is going to affect how well you are able to learn to operate it. Make sure it is designed to fit you. This can be some what tricky because many people learn how to ride a motorcycle on one that belongs to someone else. However, you need to make sure the motorcycle isn’t too heavy for you. It is important that you are able to touch the ground with both feet. Reaching the gas, brakes, and handle bars are essential as well. It is a good investment to find a cheap used bike that fits your body well. Once you have successfully learned to ride it well, consider upgrading to a better bike.

Make sure you learn from someone you trust and who is patient. Nothing can add to your insecurity as someone watching over you, especially if they are concerned about you damaging their motorcycle. If you don’t have someone you can comfortably learn from then you are wasting your time. It may be a worthwhile investment to enroll in a motorcycle instruction course and learn from someone who is trained to teach this skill.

Once you have managed the basics of motorcycle riding, continue practicing. Just like driving a vehicle, you will get better as you practice. Avoid riding on busy streets, highways, or interstates until you are very comfortable with your riding skills. Practice changing lanes, turns, curves, and sudden stops as these are all things you will experience once you are operating your motorcycle on the open road.

Practice riding your motorcycle in a variety of weather situations. This will give you some very important motorcycle skills that you won’t get anywhere else. You will be amazed at how different your motorcycle operates on a sunny day versus a very windy day. Being prepared for a variety of riding conditions is going to make you a much better operator. In time you will feel comfortable enough for long trips, maybe even to some of the wonderful motorcycle rallies that take place each year.

If you start small and practice hard, learning to operate a motorcycle will be a very rewarding experience for you. Too many beginners want a new motorcycle or the same power as their friends. They either find the motorcycle to be too much to handle or seriously injure themselves riding it. This can also cause you to loose interest in the idea of learning to ride it, and result in your selling it.

The motorcycle learning process can be a great experience if you aren’t in a hurry to be driving it fast on major road ways. Like anything else, your skills will only improve as you practice and learn from your own mistakes. Operating a motorcycle is a challenge that you will proudly succeed at if you work hard and follow the safety precautions of the road.

Modeling Student Behavior

Sunday, April 5th, 2009

Whether you as a teacher realize it or not, you are the best model of behavior in your classroom. A large part of your proactive behavior plans should include your own behavior you demonstrate to the students every day.

You must set expectations for your students, demonstrate the behaviors, and be vigilant to correct the kids. Don’t waver on your expectations; inconsistencies will only confuse the students and cause you more problems.

If you stay calm, collected, and in control, your students will exhibit the same behaviors. The same is true about enthusiasm; if you are excited about your lesson and truly believe in its importance, the kids will respond in kind. Conversely, the kids will know when you are tired, bored, don’t want to be there, or are ‘winging it.’

If you are late to class, or don’t start on time, the kids will pick up on it and be more likely to do the same. The same is true about the way you dress, the way you act, the language you use, and your ‘body language’.

If you want your students working from ‘coast to coast’, or from bell to bell, you need to set the expectation of activity all hour. Start with a warm up, and ensure the kids are doing it. Keep them busy on activities with transitions between each. Don’t let there be any down time. Work them to the end of the period, and have them pack up when you say so, not whenever they want to.

If you want your students to quietly read in class, but you are spending that time working on other things, it sends the message that you don’t value the activity personally. Modeling the skill for the kids reinforces your belief that it is important. It shows you as a lifelong learner who values the skills you’re teaching them.

The same is true for writing, or labs, or math problems. Students rarely have the chance to see real people performing schoolwork – for many, the only examples (and role models) are their classmates. Work along with your students.

Now this doesn’t mean you have to do this the entire time. You must also supervise, coach, monitor, and actively support their learning. But you can spend at least a few minutes ‘at their level’.

Be a positive role model for your students. Don’t just explain and show the behavior; be the example day in and day out.
