Numerology The Science Of Numbers And How It Relates To Our Lives
In numerology, a tradition bound by spiritual evidence the relationship flanked by numbers and living things, all of us have three cycles, or Life Path Periods in our lifetime. To settle on a person's three Life Path Periods, person merely needs a person's date of birth. In addition, if someone's 3rd Life Path Period is 22, they are in uncommon company. The following is a breakdown of the years of birth generating a 3rd Life Path Period of 22 for the last 2000 years:
The Basics Of Electrostatics
We encounter electrostatics on a day-to-day basis. For example, electrostatics is at work when you remove plastic wrap from a piece of food, and the plastic sticks to you. Electrostatics is also at play when you shock yourself on a door knob after walking across a room filled with carpet. Yet another example of electrostatics is when you rub a balloon over your hair. By holding the balloon close to your head afterward, your hair will stick up. All of these examples are a direct result of electrostatics, and there are many more.
The science involved in electrostatics, as stated before, can be quite complicated. That said, there are more basic explanations for electrostatic behaviors and principles. Electrostatics can be studied at many different ages and learning levels, and can be taught using very simple and basic concepts. Much of science and mathematics function this same way. There are always deeper and more elaborate explanations for things, but often times simple surface explanations and observations are the most effective. These surface explanations are what we discuss here.
Electrostatics is brought about when there is an exchange of charge on two or more different objects. In fact, these exchanges happen every time two objects touch one another. Many times you will only notice the exchange when one of the objects has a high resistance to electrical flow. This is due to the fact that when an object has a high resistance to electrical flow, the charge is going to be trapped in the object for a longer time. As the charge builds and builds, it will eventually have to get rid of the charge it is carrying. This either happens through a slow 'bleeding' of the charge into the ground, or through a large discharge, such as the electric shocks you experience when touching metal objects. This is essentially a large amount of energy leaping from one surface to another.
Some examples of science products used to demonstrate this phenomenon in a controlled environment are the Van De Graaff generator and Wimshurst Machine. The Van De Graaff generator produces the electric charge imbalance that was described in the previous paragraph. When this imbalance takes place, it becomes very easy to observe the electrostatic charge building up and transfer between surfaces. This can also be demonstrated by touching the storage sphere of a Van De Graaff generator. If you are standing on an insulated surface when you do this, your hair will stand on end. This effectively demonstrates electrostatic power and transfer. Science products like the Van De Graaff generator and Wimshurst Machine will come with very simple directions and include explanations

Important Steps To Follow While Teaching Science And Mathematics For Secondary
Accordingly a study was conducted and eight graduate students were placed for ten hours a week on secondary school teaching.
The results were measured on the basis of their interest level in secondary school teaching prior to the study and post study. Findings were shocking as there were evident sign of low desire. The positive outcome of the study emerged in the form reasons given by the students about their low desire to become secondary teachers.
So the basic reasons for lack of quality and quantity of math and science teachers in secondary schools are:
• Their aspiration to work in higher level of science and math.
• Unruly behavior of the class and their lack of motivation to study the subject.
• Teaching was viewed as a job and not considered as career by many of the graduates.
• Teaching under school systems demands too much of unnecessary activities objected by the graduates.
There were special recruitment drives started by the president of America to recruit math and science teachers. Attempts were made to increase the quality of teaching by making bachelor’s degree mandatory to become a secondary teacher. Need for an alternative incentive beside money was highlighted. Study strongly recommended for an overall motivational

The Science Behind Omega 3 And Omega 6 Fats
Omega 3 And Omega 6
In the early 1960s it was found that omega 6 fatty acid, arachidonic acid, was converted to produce prostaglandins in the body. These substances cause inflammation in the tissues of the body, which is found to be linked with many - if not most - disease. During the 1970s, other inflammatory substances were discovered which could come from omega 6 including thromboxanes, prostacyclins and the leukotrienes. Collectively, these substances are know as eicosanoids.
The eicosanoids have important biological functions. They do not generally live long, but if large amounts are produced, then there is a net excess in the body which is what causes the damage.
Omega 3 also creates these potentially damaging eicosanoids, but they are made much more slowly, and so are less damaging. As the omega 6 and omega 3 fats compete to be broken down into eicosanoids, having extra omega 3 in the diet, and less omega 6, means that the omega 3 'wins' in being converted. This has a net benefit in terms of body inflammation.
Eicosanoids
There are four families of eicosanoids — the PROSTANOIDS - prostaglandins, prostacyclins and the thromboxanes; and the LEUKOTRIENES.
Here is a closer look at the Leukotrienes.
Leukotrienes
Leukotrienes are made from arachidonic acid by an enzyme called 5-lipoxygenase. Also closely associated with leukotriene production is the creation

Cool Science Experiments - The Way To Get Your Kids Excited About Science
As a homeschooling family we have questioned, "What have been the things that we look back on with fond and treasured memories in Science?" It is either the hands-on nature walks and finding animals, or the fun in setting up and doing an experiment with great results. Many of the experiments my children have enjoyed have been totally unrelated to any science text we may have been following at the time. Most of the successful 'science' messes have sprung up from their own interest and trying to solve a question which they have posed themselves. (Like fixing a cheap toy and making it far better than it ever was.)
So, how do we encourage our children to play around with Science?
* Ask them Questions
Firstly, ask your children questions without giving away the answer. If you are working through a text which has science experiments, present the question to them and don't read or let them read what sorts of results they should be getting from performing the experiment. Ask them questions during the experiment and after it - what do you think would happen if we changed x,y or z?
Ask them questions about life - about their physical environment or why things happen? Ask them the curious questions before they ask you. And then let them think and ponder about it. It does not mean that you should never give answers, but at the same time, do not rush in - give them time first. When answering, relate the answer to their current experience. And remember, it is okay to admit you do not know the answer - that can become an ideal time to discuss how to research and find answers we are looking for.
* Let them Experiment
Let them play with all sorts of things around the home and experiment. Using a book or Science course will give you ideas about exciting science experiments. There are also a ton of books at the library that will interest your children. Recently, I discovered an online Science Curriculum which is full of really cool science experiments. You can see science experiments listed here.
The experiment instructions are also on video, which we all really love watching. Using all sorts of common household materials, and some that you need to buy, these experiments have amazed and excited my children. In fact, it has been the recent catalyst for a whole heap of hovercraft experiments which in turn has motivated my other children to fiddle with a toy gun changing it from a gun using air pressure to one using spring mechanics.
* Be prepared, Grow a collection of Science Tools and Encourage Mess
If you want your children to experiment, you will need to accept and even encourage mess. Set up some boxes where you keep all sorts of odds and ends which will come in handy for science experiments.
You will need materials like rubber bands, straws, pipe cleaners, paper clips, balloons, popsicle sticks.
You will also need tools and materials to bind items together like sticky tape, masking tape, hot glue gun, super glue, rope or string, stapler and staples, hole punch, scissors.
Then you will also need to collect some clean junk - bottle tops, soda bottles, clean cans, bottle lids, icecream containers and cardboard boxes of all sizes.
Perhaps you can create a Science Corner - filled with experiment books and all the materials, and a table to work on.
* Allow for mistakes
Every Science experiment does not need to work perfectly and make sure your children know that. When an experiment does not work the way they had hoped, ask them, "What did you learn from that?" "What might you do differently next time?" "Why do you think that happened?"
* Be Curious alongside of them, but do not take over
When your children are in the middle of a project or have completed it, they love to have a fan club. As they become more independent, they may not need you to set up an experiment or help them do it, but they really want to share their enthusiasm with an interested party - like their family and parents! So, let them inspire you - cheer them on as they set up an experiment - ask them questions so they can verbalize what is happening and why - problem solve with them - search out answers together, BUT do not take over.
As parents we have the tendency to ruin the child-led learning experience and make it a full-blown lesson. We want to run with their idea because we can see how it will make a wonderful 'unit study' and so we plan, get books, blah, blah, blah, and run off with all of our great ideas, but meanwhile our children have turned the corner, lost interest and moved on. It does not matter! Even if their interest in that topic may have been short lived, another experiment at a later date will most likely, help to reinforce the science concept.
So, do what you need to do to excite your children about Science

Science Fair Projects Ideas Using Elenco Electronic Lab Kits
So why is it important for beginner electronics students to always use an electronic kit from a reputable brand, such as Ramsey, MadLab, Amerikit, or Elenco Electronic Project Lab? It is important because high-voltage electricity can be deadly without proper precautions, students can safely explore electricity with low-voltage electronic kits. Even at low voltages, electricity can be dangerous if not handled properly. Products like Elenco Electronic Project Lab avoid dangerous activities like soldering and use only battery power, which is much safer than AC power.
Another benefit of using electronics kits is they come with detailed instructions, which is very helpful for beginners. Before doing any experiments with electronic kits, students should read all directions included with the kit and follow those directions exactly. Improper use could result in fires, property damage, or even personal injury. Reputable brand name products like Elenco Electronic Project Lab include a lab manual with step by step instructions for every electronics experiment.
So here are a few ideas for projects. The simplest experiment with electricity might be an exploration of conductors versus insulators. A conductor is simply a material through which electricity will flow with little resistance; an insulator prevents electricity from flowing. This can be tested by creating a simple circuit with a battery and a light bulb. If a material completes the circuit, the light bulb will luminesce, indicating that it is a conductor. Most metals are conductors, while most nonmetals are insulators. Therefore, it will not be a surprise to see that silver and copper are conductors, while cotton and glass are insulators. However, you may be surprised by the results of lead (a metal) or graphite (a non-metal).
Depending on the requirements and the amount of time allotted for the experiment, another interesting and particularly applicable experiment would be an exploration of light bulbs. Which light bulb is the best value for the money? The student can explore the differences between brands or between types of bulbs (incandescent, compact florescent, or halogen). At the end of the experiment, the student can compare the price of each bulb to the number of hours the bulb burned. This experiment may require a closet or a room away from the bedroom, so that bulbs that remain on during the night will not awaken the family.
Another interesting and low cost experiment would be an exploration of temperature on the output (in volts) of a standard alkaline or dry cell battery. Another, similar variable would be the output of different brands of batteries (Energizer, Duracell, Eveready, etc.). If enough time is allotted for the experiment, the student can also explore the lifespan of a battery, and whether the battery will last longer if it runs continuously or if it is started and stopped on a regular basis. Any combination of these variables can form a fascinating hypothesis.
Part of the adventure of a science experiment is using imagination to explore a particular aspect of the world around us. Using this imagination, a student could explore a different application for an existing electronic device. For example, the student could investigate the possibility of creating a different type of clock that expresses time using lights instead of numbers. Similarly, the student could explore rewiring a low-cost radio to improve sound.
Creating a science experiment using electronic kits is a way for a student to explore a scientific hypothesis while still having fun. The hands-on style of science experiments is a particularly unforgettable experience. In the 21st century, career opportunities in electronics and technology are expected to abound. For many people, their interest in these industries begins in childhood
