How to Plan A Science Project by Jimmy Cox

Although the best science projects seldom are created according to a recipe, there is an orderly series of steps that is followed pretty universally by successful students and professional scientists.

Seven Steps to a Successful Project:

Decide on the specific problem or process you want to investigate.

Think it through, planning progressive steps, controls and checks in some detail. Try to foresee blind alleys before you become stalled in them. List unwanted factors that might influence your results and plan ways to prevent or make use of such accidents.

Read widely, since success with science projects depends largely on how much you know about your subject. Such reading will increase your understanding of the possibilities and limitations of your project and help you to see it in context. In addition to your school library, try the public libraries in your vicinity, and university, college and specialized libraries for books, journals, monographs and theses on your subject.

When you have discovered relevant materials, dig into them deeply and take accurate notes, being sure to keep a complete record of your sources so you can give proper credit for borrowed material. If very little has been published in your field of investigation, at least you will know this and can include a statement to this effect in your project.

Talk to other people about your project and consult them about your plans. Often another student or an adult can find a fuzzy area in your thinking, detect an error or suggest a method that will save you many hours of work or frustration. When you have gone as far as you can alone, professional scientists and technicians usually will be glad to help you over the rough spots.

You will, of course, be considerate about querying them when they have time to answer, and only after you have done enough reading and thinking to be able to ask really intelligent questions. If you do not abuse their helpfulness, you may find adults eager to offer suggestions and even to lend you equipment, publications and other materials you might never discover for yourself. However, do not write an organization to send you everything it has on the subject, or expect the staff scientists to do your project for you.

Set up a notebook that will include accurate records of your original ideas, good and bad guesses, notes on your reading, all of your experiments and observations and graphs, tables, drawings, photographs or whatever is relevant and useful.

Begin the experiment or progressive steps of your project and establish the controls against which you will check each result. If the experiments do not yield the information you are looking for, record the results anyway and salvage whatever is useful in designing new experiments and controls. Remember that failures are instructive too. It often is extremely valuable to know what does not work.

Summarize your conclusions, when you have repeated your experiments sufficiently often to feel sure that your results are valid. Your conclusions may be positive or negative, since it is often as useful to prove a hypothesis false as true. If your work on this project opened up new questions that you hope to investigate, by all means mention these, too.

Writing a Report

Although there are many ways of writing about scientific work, the usual form for a written report is something like this: Title - accurate, but not self-consciously long in an effort to impress Summary - brief statement of the problem and the gist of your research Introduction - reason for your interest in the problem, relevant work done by others, background information Discussion of problem and hypothesis you are investigating Details of materials, equipment, methods, steps of experiments, controls Summary of observations and data Conclusions drawn from observations New questions, possible applications, future plans, if any Appendix - graphs, tables, photographs, drawings Bibliography and acknowledgements

Now you know the basics, it is time to start your own scientific project!

An Undersea Lab Used For Outer Space by James W. Smith

The only underwater laboratory in the world is located in the Florida Keys National Marine Sanctuary. This underwater lab is located more than three miles offshore at a depth of 63 feet. It is attached to a base plate which secures the laboratory about 13 feet off the bottom of the sea. The laboratory is known as Aquarius and is owned as a joint venture between the National Oceanic and Atmospheric Administration (NOAA) and the University of North Carolina.

Scientists live and work inside the habitat when they are not exploring outside on the adjacent coral reefs. Entry to the module is through the "wet porch," which contains an open moon pool, dive equipment storage areas, hot water heater, and shower. There are two main compartments in the Aquarius module. The "entry lock" contains space for computers and experiments, power equipment, life support controls, small view ports, and bathroom facilities. The largest living space is in the "main lock" which is designed for a six-person crew. This area has computer work stations, two large view ports, and kitchen facilities. The kitchen facilities include a microwave, instant hot water dispenser, refrigerator, sink, dining, and work areas. The main lock also contains life support controls, so both the entry and main locks can be independently pressurized.

Since the early 1990s scientists have lived in the lab and explored the deep ocean in missions that can extend up to ten days in length. The laboratory is at a depth which requires 17 hours of depressurization for divers who stay down for more than a couple of hours. Scientists use a special technique called "saturation diving." Saturation diving refers to a condition involving a diver who is underwater for several hours. After this time, the diver's blood becomes saturated with gases. The diver will require the same amount of time for depressurization whenever he or she comes up to the surface.

Using Aquarius, the diver does not have to resurface and depressurize and can explore for days under water. Therefore, the module provides tremendous time savings for researchers. Scientists living in Aquarius can do work in days which would require weeks to accomplish if they had to dive from the surface. Research scientists usually stay for about 10 days in the Aquarius module doing research before they slowly return to the surface.

The scientists living in Aquarius have observed that life in the module is like living in an aquarium. Fish peer in every port hole and the adjoining coral reef is a habitat to many different varieties of fish. Aquarius is connected to the world above the ocean by a wire secured to the top of a 30-foot buoy on the surface that connects the laboratory to Key Largo. This connection allows the scientists to send an educational underwater video program of each mission across the Internet.

The laboratory has been home to close to 100 deep underwater missions since the early 1990s. The undersea lab's environment is very similar to conditions found on the International Space Station. This has provided NASA with a venue to do research about conditions involving moonwalks and to test concepts designed to be used in future space exploration.

During a recent mission, called NASA Extreme Environment Mission Operations (NEEMO), participants practiced new long-distance medical techniques to keep space travelers healthy. Doctors thousands of miles away guided the aquanauts as they performed surgeries on a patient simulator. Also, doctors used virtual reality technology to guide simulated surgery by robots. The procedures simulated what one day may be used to respond to emergencies on the International Space Station, the Moon, or in long distance space flights to Mars. The aquanauts also walked on the ocean floor to simulate the lunar surface. This exercise used high-tech breathing helmets and weights to improve mobility and balance in conditions that were equivalent to the Moon's. NASA has also used Aquarius for astronauts to simulate living in the International Space Station.

Aquarius will continue to be a valuable research facility for NASA for the lunar and Mars missions in the years to come. In addition, Aquarius provides an important research venue to explore the mysteries of the undersea world on Earth. Indeed, the missions involving the Aquarius laboratory are providing the necessary research and experimentation for the conquest of man's next unexplored frontiers, under the sea and outer space.

Electricians Guide and Basic Electricians Information by Prince Mhlanga

As an electrician you have to bend over all the time when doing your job. It is hard to keep a good posture while working, and can be very tiring. So, try using lighter weight tools and as many hand tools as possible. Stand as straight as possible while doing work. To make the job easier on yourself wear a tool belt and only carry the tools that you will need to do for each job. Wear gloves, knee pads and the proper eyewear on the job. Try and find tools that fit your hands properly. Buy tools with a good grip. Keep the area you are working in clean and free of debris so you won't fall or trip. Stand up, move around and reposition your body often. It is not good to be stuck in one position for long periods of time.

The helper

An electrician helper must also have the ability to quickly move your hands and arms, grasp and assemble objects, see details at close distance, you should be able to bend, twist, and stretch your body arms and your legs. You should have the ability to put things in order according to rules. Be able to tell when something is going wrong or is wrong, solve problems easily and recognizing problems. You should have the ability to keep your arm and hand steady, grasp and assemble small products when needed, and quickly adjust controls of a machine or vehicle to right positions.

Electricians wear

The safety and health administration has been working very hard to provide safe work environments for electricians along with other individuals who work in this type of field. If you work as an electrician you should know what type of clothing you should wear just by the weather and the conditions of the area that you will be working in. It is good to be prepared and take other clothing items with you if you are uncertain of the circumstances. A experienced electrician learns how to dress in any kind of weather or condition that they have to work in. An electricians clothing should be tight fitting but comfortable. Tight fitting clothing will help to avoid the danger of being caught up in moving machines. And comfortable clothing will help you to do your work better and move around easier.

Tools used by electricians

Labeling machines are used by electricians to properly label their work at installation. This saves time for an electrician being able to label items. Electricians use lightweight smaller power tools. They are safer and easier tools to use. The most used power tools for a electrician are saws and drills. Every electrician used drills when doing their work. The type of drill needed depends on the job being done. And the material you are going to be using the drill on. Saws are another tool that electricians use on a regular basis.

Electrician jobs

Electricians can work in either construction or maintenance. Some work in both. If the electrician works in construction they install electrical systems inside of houses, buildings and also factories. If a electrician works in maintenance, then they have to monitor and repair electrical equipment. Electricians use special tools such as knives, drills, pliers, screwdrivers, saws and other tools they need to do the job. Some of the jobs a electrician does can be risky so they have to wear the appropriate clothing to protect them from a accident. And appropriate foot gear to prevent them from slipping or falling in unsafe work areas.

Electricians also need good color vision for the wiring they have to work on in homes and businesses. They must be able to tell what different colors are. Electricians need to be very good at math and solving problems. It is also good for them to be able to communicate in Spanish as well as English. There are a lot of Spanish workers that are in this work field and in construction. It is good if you can communicate better with them. This will help to get the work done faster and make the job go smooth.

Electricians: Some Basic Facts You Should Know by Johnson Maseko

Electricians maintain electrical systems for residential homes and businesses. Most electricians specialize in doing work in construction or maintenance. But anymore more and more people are doing both types of work. Electricians test, install and maintain electrical systems for many purposes such as climate control, communications and security. Electricians also do work in business and industry. Electricians have to follow the proper building codes when installing electrical systems.

Electricians need to wear the right clothing while doing their job. They should dress in appropriate clothing that is tight so that is does not get caught up on anything when they have to work in tight surroundings. They should always dress for the weather. Sometimes electricians have to work in very cold and hot temperatures. They should always dress properly for the weather to be comfortable while doing their job. It is important for an electrician to always wear good work boots. These work boots should have good traction so that there is no slipping or falling on the job. Sometimes an electrician has to climb and walk on wet surfaces. Wearing rubber boots can keep them from slipping and sliding around on wet surfaces where they have to walk.

Most states require an electrician to have a electricians license. But having a license varies from state to state. Most of electricians work of forty hours a week. Sometimes their work carries over to the night and sometimes even work weekends. Electricians that work in a factory normally have three shifts that they can work. Electricians need to become skilled before they can work as a electrician. Electricians should have good hand eye coordination to be able to do the job properly.

Electricians also need good color vision for the wiring they have to work on in homes and businesses. They must be able to tell what different colors are. Electricians need to be very good at math and solving problems. It is also good for them to be able to communicate in Spanish as well as English. There are a lot of Spanish workers that are in this work field and in construction. It is good if you can communicate better with them. This will help to get the work done faster and make the job go smooth.

As the population and economy continues to grow electricians will be more in demand then ever. Electricians will be needed to install and maintain electrical wiring and devices in homes, offices, factories and other places. New technology will also continue the high demand for electricians. Electricians also pre wire buildings during construction to get the buildings ready for the use of computers and telecommunications equipment. More factories will go to using robots and automated manufacturing systems. The demand for electricians will increase due to installation of this type of equipment. The demand for electricians will also increase due to rehabilitation and retrofitting of existing structures.

The amount of job opportunities for electricians in any given year will vary widely from area to area. Depending on the growth and change in the communities. There are some parts of the country that may experience a large supply of electricians while other parts of the country may have a shortage on electricians. It will all depend on the area of the country as to what the demand for electricians will be.

There are several skills that are important for a electrician to know how to do. They are manual skills, troubleshooting skills, technical speaking, knowledge of electrical materials and concepts, electrical circuit knowledge, customer service, the ability to find solutions in electrical systems, mechanical skills, commercial wiring, physical fitness, eye hand coordination, and strong math and English skills. All of these skills are important to know if you are an electrician. If you are a electrician you need to have good problem solving skills, and the ability to work in all kind of environments including hot and cold temperatures. A candidate should obtain an electrician license to become an electrician. An electrician license is required in many areas. But they can vary depending on the area.

Electricians: Education Requirements and Job Lookouts by Elias Maseko

An electrician apprentice can complete an education program within 4 years time. This can happen by having hours of classroom studies and hands on training at a job each year. The electrician program course may include the following subjects that you need to know. They are soldering, safety and first aid practices, fire alarm systems, electrical code requirements, blueprint reading, diagrams of electrical systems, conduit fabrication and communications. A formal electrician education is not required, but employers find it to be an attractive thing to have when you apply for a job. It can also help to advance your career as an electrician if you have skills.

Industrial electricians can choose to work with machines and other large equipment. A maintenance electrician can work in factories, hospitals and other places that need repair, replacing and the maintaining of electrical systems. A maintenance electrician would be in charge of inspecting equipment, working on electronic devices, and replacing items like circuit breakers and switches. A commercial electrician could be involved with repair work and maintenance in factories and office buildings. A general electrician is commonly found working in residential homes, rewiring homes, replacing fuse boxes, and fixing problems with lighting.

There are many different schools you can attend to further your desire to become an electrician. Along with getting a good education you will learn everything that you need to know and do to become a skilled electrician. Learning to become a skilled electrician will take a lot of time and effort from you. It takes a lot of hours of schooling and hard work. Four years is the typical time in school to become an electrician. Many things are learned in the four years about electricity and how it works.

Learning to become a electrician can be a long and hard profession. Just like any other profession a electrician must be good at what they do and have the right training, skills and knowledge to do their job right.

Job outlook for electricians

How to Choose A Topic for A Science Fair by Jimmy Cox

Stumped for a good idea? Interesting project possibilities can be found almost anywhere you look.

During late fall and early winter of every year, at thousands of high schools across the country, hundreds of thousands of prospective science fairers buckle down to the task of selecting a project. Finding a suitable theme or topic is the first and, without question, the most important step in planning a winning project. Every future decision about building the project, where to shop, who to speak to, and how to orient the display and presentation at the science fair hinges on the topic.

There are no set rules for choosing a topic; everyone goes about it slightly differently and in his own way. But there are pitfalls to beware of and factors to carefully consider before making a selection. Perhaps the best words of advice that can be given to anyone planning a project are to look hard and long before you leap. A hasty decision so early in the game might easily "KO" your chances of finishing in the winner's circle at the science fair if you finish at all.

Allow yourself plenty of time to consider your own interests, abilities, talents, academic level, and the advice of teachers and professional scientists you have spoken to before you make your decision.

Reading, reading and more reading! Only by gaining an extensive background can you intelligently choose a subject and execute your project. Often, the study of many related fields will be necessary.

Project ideas can also be gleaned from hobbies and school work.

An interest in amateur radio has been the inspiration behind many science fair projects in the field of electronics, an area which offers numerous possibilities to experimenters. Ideas for a project? You are constantly being bombarded with them! Even advertisements can be stimulating.

Professional scientists, educators, and other qualified persons are often willing to help with ideas, equipment and advice. Make as many contacts as you can among the professionals in your field.

Popular magazines can help you choose a topic. Don't copy; add a new twist based on your own ideas.

Interest in rocketry has resulted in a number of projects. Your best bet here is to confine yourself to one aspect of the subject: a new fuel, design of a component, etc.

A handy rule of thumb to keep in mind is that you are judged on HOW you solved the problem. This is a mighty big "how," and covers a lot of territory. Originality is, of course, of prime importance; so is creative ability.

But also included are the approach you took, your technical skill, your adherence to scientific method, your research into the work of professionals in the field, and your method of presenting results and conclusions. The last point is very crucial as the judges will expect conclusions about each individual facet of your project and will require good reasons for everything you display at the science fair.

Your project will represent YOU at the science fair, and will take many hours of YOUR time to complete. Therefore you and you alone should choose the topic that most interests you. Ask advice from others but make the final decision all by yourself.

Getting a round peg into a square hole is easy compared to completing a project on a topic that doesn't really interest you. At the same time remember that you must demonstrate that you solved your self-chosen problem. Consider everything the solution will require and weigh this against your assets of skill, knowledge, and ability before you start.

Once you have selected your topic, you have already accomplished a lot. Now to finally bring your idea to fruition. Good luck!
