Science Lab Equipment Makes Learning Science Fun
February 20, 2010 | Leave a Comment
Getting your children to become interested in science is often a difficult task. With the use of kid friendly science lab equipment and some easy projects the kids will be begging to do more science oriented projects. And will soon be searching ideas of their own unique ways to implement science into fun.
Parents have difficulty with science sometimes as much as their children do. They have the idea that it takes rocket science degrees to become science oriented. The following projects are super easy and fun. They will get your kids not only having fun with science but eager to do more.
This first project is great for teaching things such as how stuff grows, the process involved and the end results with a lot of indiscreet learning in between. As you complete each step explain the process in kid friendly terms and encourage them to ask questions. Both projects are only four easy steps but packed with information.
For step one, purchase some science lab equipment like inexpensive sponges. The sea sponges that are used for crafts and painting work great because you can give explanations about where they come from. Use a microscope to let them view what the sponge looks like dry and wet. If using cellos sponges the kids can cut shapes from the square sponge. Use this as an opportunity to learn geometry.
Step two teaches why water is needed for growing food and plants. Soak the sponge and place in a baggies that has been filled with seeds of your choice. Roll the sponge around in the bag until it is covered with seeds.
Step three: tie a piece of string around the sponge or if preferred feed string through a hole in the sponge. Hang the seed covered sponge in an area that will provide lots of sunlight. In a week or less there will sprouts forming on the sponge.
Step four will teach them how to care for the plant and the result of caring for them. When sprouts have begun, remove string and place in a clay pot that has been half filled with potting soil. Sprinkle soil over the sponge and put in a sunny area until fully grown.
Parents and kids of any age love to do this next project which is a lava lamp of sorts without the light. To start fill a jar with two cups of water and few drops of food coloring. Stir will and set aside. This will teach your children how to use measurement and mixing.
Step two is adding the oil. Measure a half of cup of vegetable and pour into the jar of colored water. Allow to sit for a few minutes so the oil will separate from the water.
In the third step kids learn about weight and gravity. Without shifting the jar pour a teaspoon of salt directly in the jar. When the salt lands on the oil it will form some clumps. The clumps will begin to sink due to the weight.
Step four encourages the learning of movement, gravity and separation. After the clumps reach the bottom the salt will start dissolve and cause the oil to float back to the top. Each time you want to sink the oil, just add salt.
Science is fun for parents and children. It encourages children to ask questions and look up the answers with their parents. The more gadgets kids have the more interest they have in using them. For gifts opt for microscopes and other science lab equipment to encourage learning science.
Since 1970, the premier retailer for science lab equipment offers a wide variety of resources to young aspiring scientists. Children can learn about alternative energy with educational science toys, or about solar power with high-quality energy equipment.
How Electricity Is Produced From Wind Energy
February 8, 2010 | Leave a Comment
Wind energy has been used for many years as individuals have used wind power for sailing, wind mills for manufacturing and pumping water and more recently conversion into electricity using wind turbines. Wind power is a renewable energy that is considered a good option instead of burning fossil fuels. Of all the renewable energy sources it is the most efficient and you only need a light breeze to produce electricity.
The very first uses of wind for energy was in the form of wind mills and sailing as people have been using wind for more than thousands of years to propel ships. Windmills have also been used for many years for milling grain as well as pumping water for irrigation. These irrigation windmills was the main reason that farming and ranching could occur in the US, as there are vast stretches of land that do not have ready access to water.
The very first usage of wind to create electricity occurred in 1888. The first wind turbine was used to create hydrogen in the 1890s but it was soon converted to producing electricity. Small wind turbines are used to provide power to rural buildings and today there are larger wind farms that are being used to produce electricity for large networks. What is known as the modern wind industry really began in 1979 when wind turbines began to be regularly produced.
Wind occurs because the surface of the earth is not evenly heated, as the poles get less sunlight than the equator. This causes cooled and heated air to move which in turn produces wind. It is projected that the amount of power that could be harnessed form the wind is more than the human population currently uses. So just think about having almost cost free power.
The amount of power that is generated by the wind is dependent on the speed and as the wind speed doubles the amount of power produced increases eight fold. However there is a cap as wind turbines can only go so fast and generate so much energy. You do not need high winds at all time though as a lot of energy can still be produced with 15 mph breezes. As such, wind power is a valuable method for alternative energy.
The main issue with wind energy is storage as wind power cannot be dispatched at different times but needs to be used immediately. Many companies have looked into different types of batteries, storing it within the energy grid and even hydroelectricity. Many times surplus energy from domestic wind turbines are fed back into the electrical grid and the energy company will purchase this energy and you will receive electricity credits.
A wind turbine used to collect the power of wind will contain a rotor shaft, gearbox and brake assembly. Generally within a wind farm the different turbines are interconnecting for power collection and communication networking. Wind energy uses induction generators to collect the power and change it to electricity.
The best types of generators are doubly fed machines as they will function when errors occur within the grid. You need to be aware of the power factor, dynamic behavior and frequency constancy when a system fault should occur.
Wind power should be thoroughly considered in order to promote a greener society. Educate your children to become future scientists by purchasing them science lab equipment.
Wind Power: Saving The Environment, One Kilowatt At A Time

More of us than ever are concerned with both protecting the environment and our wallets. People used to think that using alternative energies would simply be too costly to ever be practical, but with the rising costs of energy, many are starting to change their position.
The cost of installing a wind generator is a lot less than you may think and it quickly pays for itself by saving you a lot of money on your electricity bill. There are also a variety of incentive programs to encourage people to switch to alternative energies. These programs may allow you to be reimbursed for part of the cost of installing your wind generator.
You are not the only one that is concerned about saving the planet so this is why it is easy to find that you will not only be encouraged to take such steps but you can also be financially helped to do so. Not only will the installation of the wind generator save you money by not paying so much to the electric companies, but you can also sell the energy produced.
Electricity suppliers are required to buy the extra energy generated by consumers who use wind generators and other alternative energy sources who produce more than they can use. You’ll be doing your part by powering your home with clean energy and by selling the excess to your local utility; you’re also supplying clean renewable energy to other households in your area!
You are also making some money while doing it so it is truly a win-win situation for everyone involved. And if you are worried about whether or not you will be able to efficiently install the wind generators, do not worry. There are many step-by-step instructions available out there. It is a pretty simple job and as long as you are installing it all on the top of your house, you will be able to capture as much wind as possible.
In case you ever need more electricity than you’re generating at the moment, you’ll want a backup supply. Leave your existing electrical system in place so that you won’t suffer power outages.
You’ll also want to stay connected to your local utility company because this allows you to sell them your surplus electricity. When you make more than you can use with your wind generator (which will be more often than not), then you can sell the extra. You’ll also be using clean energy and helping others to do the same. Naturally, the larger the turbines you install, the more power you’ll produce.
This does not mean that you have to go with the largest that is out there though if that is not something you can afford at this time. Over time, you can add more and more generators, or larger ones, and you will be able to see that you are bringing in much more renewable energy.
See how you can build residential wind turbines for your own house and save cash on your electric bill. Making your own wind power generators may save you hundreds on the cost of buying one at the store as well and still make lots of power.
Tips For Using Solar Power
January 16, 2010 | Leave a Comment
With recent tax incentives for solar power a lot of people have been researching to find out if they qualify. The easy answer is yes you will qualify for the tax incentives if you have a system installed. It tends to be a bit more complex than that however. The systems may be more expensive than most can afford even with the tax incentives.
This is energy generated by the sun. To harness that energy you need a special system in place that will transfer sunlight into power that will run the electrical devices in your home. These systems usually consist of panels and converters. They must be installed by licensed professionals for safety reasons. You local electrical company may have personnel on hand as well.
The do it yourself kits look like something I would love to try if only as a science project for my son. These promise that anyone can do this but I have a hard time believing I could set up a system like this. Any time electricity is involved there is also a certain amount of risk. Fires, explosions, and electrocution all come to mind.
I have no doubt that solar power is the way to go if you can. Not only can this cut your electric bill but it is also earth friendly. In years to come we may well see the end of fossil fuel use in countries around the world. This fuel simply can’t last forever and alternatives must be found.
One of the great things about energy from the sun is that it can be used in combination with other energy sources. This means that you can have your normal power hooked up and when there is no sun, even for days at a time, you will still have power. This makes it very stable and you never need to worry about being without power.
At least one site did mention the need for permits. This may be a very complex project and you will need to do some research before trying any do it yourself kits. There are special boxes needed and it sounds fairly complex.
Some of the products that run on solar power are nice and you don’t need a special system installed. The outdoor lights look really great. They are easy to install and no cords to run or trip over. The cars are still a long way from being marketable though.
If you are thinking about going with solar energy then check all local laws regarding this and at least get professional advice before you begin. Keep in mind that any time you work with any type of electricity proper precautions must be taken and safety should always be your first priority.
Solar energy will no doubt be more widely available in the near future. Prices may come down a lot in years to come. If you can afford to go with this now then you could save a lot of money. One day they may even have solar power companies that actually charge us for solar power.
Solar power provides an efficient and environmentally friendly source for energy. In order to promote a greener society, wind power should also be considered as an alternative option.
How Save On Your Electricity Bill

Every month when that electricity bill slides under your door, you feel that hole being drilled in your pocket. The electricity bills these days are huge! The time has arrived where we should consider taking electricity into our own hands, and taking measures to reduce the electricity bill. We would like to share some tips with you and help you save money by lowering your electricity bill.
You should discuss the importance of saving electricity with your family members. If they seem to not take it serious reward them with a treat if they helped with saving electricity each month. Suggest to them ways to save electricity like switching off lights or taking a sort bath or shower. Also tell them to switch off all the appliances if they don’t use it, even if they are only gone for 10 minutes. It seems like nothing but every little bit helps.
One should plan to invest smartly on power. Replace all the incandescent bulbs present in the house with compact fluorescent light or those CFL bulbs. These bulbs consume less electricity as they consume less power.
Buy the energy saver gadgets that are available in the market. Such gadgets will monitor the intake of the entire power supply in your house and makes you take decision on how to control the usage.
Don’t assume that a rise in the electricity bill is due to all the appliances you own. The truth is that the appliances that are turned ON are the problem, so only monitor them and see where you can save some electricity.
Do take some effort to control the following items regularly because they are the ones that consumes the most power:
1.) If you have an old computer, switch off the monitor when you are not using it as old CRT monitors use large amounts of electricity. 2.) Only use the washing machine when it is loaded at 100% capacity. 3.) Turn the geyser off when you are not using it. 4.) Never use the air conditioner when you are not forced to. It consumes a lot of electricity. 5.) Be sure not to use typical electronic items regularly that consume a lot of power.
If you are very serious in your effort to reduce your power bill, you should consider into using energy saving guides. These guides show you how to produce your own home made electricity by building solar panels and wind turbines. Many guides exist and it would be smart if you make use of them!

Our Sun Gives Our Earth A Free Power Supply: Solar Power Is Untapped Energy
December 24, 2009 | Leave a Comment
We are ignoring the cheapest and cleanest power source on the planet - our Sun. Natural energy is provided to the Earth by the Sun every day. The energy is easily harnessed by us and it can be used to reduce foreign dependence on oil as well as help the environment. Solar power is untapped energy and that should change.
Energy problems that the Earth faces can be eased by the power of the Sun. Everyone wants to find new and renewable forms of energy, but we already have one available. Solar energy is a great opportunity for our world that we cannot pass. There are numerous reasons why solar energy will benefit the Earth and our society.
First: Solar energy is quite a clean energy source.
Solar energy use reduces the amount to CO2 that is released into the air by our homes, businesses, and power plants. Reducing CO2 levels can slow down global warming and may even preserve our world for future generations. At the very least, the air we breathe would be healthier for us and our children.
Fact 2: Solar Energy is a very inexpensive form of energy.
Solar energy can provide most of the electricity needed for most homes, offices, and businesses. The energy is mostly free as well. The biggest expense in concerting to solar energy is in installing the equipment. Solar energy is free after that expense.
Reason 3: Solar energy is renewable energy.
The will not run out of rays to send us simply because we are using too many of them; the Sun will keep sending rays to the Earth as long as it exists. It is safe to use the energy that the Sun sends our way. Energy that comes from the Sun’s rays is completely renewable. It actually renews on its own!
One of the biggest concerns that people have about solar energy is that they will be without electricity on cloudy days and some areas have long months of cloud cover. Clouds may block out some of the Sun’s rays, but they do not block them out completely; you will just collect less energy on these days. Solar energy is not used in real time; it is converted to electricity and stored in a generator so it can be used as needed. A back-up power source is still recommended, but that would be more secure even than the methods we use today.
Just switching to solar energy would greatly reduce pollution to the Earth and the expenditure of natural, un-renewable resources. These reasons alone are enough, but if you need a better reason consider that solar panels can qualify for a tax credit and after you put them in, most of your energy will be free.

Solar Energy Made Easy And Simple

Alternative forms of power are becoming an important factor in the earth’s future, especially with all the worry and debates going on about global warming. Here are some facts on how solar energy works. A non-mechanical gadget, a solar cell, is made up of silicon alloys that help it convert energy into electricity.
Thousands and thousands of photons make up solar rays that reach earth. These photons hold different amounts of energy that correspond with their matching patterns on the solar scale. Solar cells pull on this energy and when electrons hit the surface of the cell they either go straight through, reflect, or absorb into the device.
In order to produce energy, enough of the photons have to be absorbed so as to gain a certain amount of electricity. When that happens the electrons are dislodged from the atoms. Whether or not the solar cell has received a certain type of treatment, then the more receptive it will be to any wandering electrons floating around.
Negatively charged electrons migrate towards the surface then the imbalanced charge between the two sides of the cell turns the cell into a battery. One side with a positive charge and the other with a negative so that when both sides are connected through external means, a plug for instance, then electricity is produced and begins to flow.
When the two sides are connected by external sources, electricity gets produced and begins to flow. A solar cell can be anywhere from 0. F inches to 4 and one cell can produce 1through 2 watts of power, which isn’t enough to run our smallest electronic contraptions. At least not by itself, which is why they usually come by the dozens unless inserted in a small device like a night light, outdoor lamp, etc.
The data gotten from these electronic signals is then moved to an acquisition system where they’ll be stored to be checked on an intermittent basis. The electrical distribution panel sends energy from the solar cells and combines it with other electricity, then routes it through a building to power any device that’s consuming energy.
Solar energy is quick and efficient and because of that it is one way you can be sure to lower your monthly electricity bill.

An Introduction To Wind Power
December 20, 2009 | Leave a Comment
We all know how important it is to preserve our environment and conserve natural resources. This has led to an unprecedented level of interest in using wind power and other types of alternative energy. However, a lot of people really aren’t sure how wind power actually works. In fact, it’s actually rather simple. The kinetic energy of the wind is converted into electrical energy through the motion of wind turbines.
While wind power is a promising source for and inexhaustible supply of clean energy, it makes up only 1.5% of the total electrical supply worldwide. However, it is becoming a more important part of the global energy picture every year.
The more people know about the danger posed by continuing to produce electricity by conventional means and the benefits of wind power, the more people are interested in making the transition. There are some countries which have made great advances in the use of this alternative energy technology; Denmark already uses wind power to meet 20% of its electrical energy needs.
Portugal and Spain have able eleven percent wind power usage. And it is seven percent in the Republic of Ireland and Germany. Even though it would seem like a natural transition being wind power has historically been used for pumping water, grinding grain and propelling sailing ships, it has only been until the recent years that it was being used for the production of energy that can be used as electricity.
There have been those who criticize wind farms for being unsightly, though anyone who thinks about all of the benefits to be had from using wind power tends to quick rethink this position. Wind power is an unlimited source of clean energy which produces little to no pollution.
Wind power can produce the electricity we need to power our homes and businesses, but there may be even more than this that wind power can do for us. There has even been a car developed which can run on wind power! The technology isn’t quite ready for the consumer market yet, but it shows a lot of promise.
These cars use a solar-charged battery to start, but once they’re on the road, they run on the kinetic energy of air circulation! Wind power could be the answer to many different energy problems faced by the world. It can power our homes and someday may even run our vehicles; there are few, if any downsides to using wind power.
Of course, some who live near a wind farm do have some complaints about the noise, but other neighbors of wind farms shrug it off, saying that these wind power plants produce less noise than a herd of sheep or cows would.
Whether wind farms or regular farms are noisier is a matter of debate. However, it is hoped that adopting this alternative energy will be done in the interests of society and protecting the environment, rather than on the basis of what the neighbors will think.
Wanna see how to build a wind generator? It’s simple and you’ll be able to build a strong generator that doesn’t cost very much money. Learning how to build a home wind turbine can really reduce your power bill and help the environment, too.

Energy resources are very important. The energy resources are renewable and non-renewable. With the fast growth of technology our dependence on non-renewable energy resources is increasing day by day. This has started becoming a danger for environment. In addition non-renewable energy resources are expensive also. The best possible option that can substitute non-renewable energy resources are usage of home made solar energy.
Statistics
Recent survey states that more and more people are getting interested in learning about homemade solar energy. Few countries like Israel have made solar energy mandatory to be used.
Why Home Made Solar Energy?
The reason for such a large number of people preferring homemade solar power is that it is an excellent way to lower your power cost. In case used as electric power, it may reduce your whole monthly expenditure by around 80%. Also it is environment friendly; thus it helps us in saving our environment. Apart from being the cleanest power source, homemade solar power is the most abundant power resource on the earth.
Home Made Solar Energy: A Solution to A Major Problem
Using home made solar energy at our house not only helps us in saving our money, but it also makes us a part of the solution to the major global problem. We all are aware of the adverse effects of the uses of nonrenewable or conventional energy resources on our environment. At this point, it is very important for us to use non-conventional sources of energy, and homemade solar energy helps us in doing so. Therefore when we use solar energy, we actually are a part of the solution.
Cost Factor
The cost for setting up your own homemade solar energy system is extremely low. And moreover it is a one-time investment. The cost of a solar energy system varies from $1000 to $10000, but the cost of a home made solar energy plant is $100 to $200.
With s many benefits up for grab opting for homemade solar energy is quite obvious. Put some effort and you too can enjoy all the benefits while you generate electricity.

Renewing Alternative Energy For A Sustainable World
November 20, 2009 | Leave a Comment
We are blessed with so much sources of energy that we can use for our daily needs. There are also lots of alternative sources of energy provided for all of us and the whole earth. Renewable powers are present in all corners of the world but these are only used by those who cannot afford or where availability is scarce of the technology of mechanical electricity.
Energy sources like the wind, sun and the geothermal are inexhaustible no matter how much we may use them, however we need to know and understand how to harness them and turn them into the kind of power that we need. This has become particularly more important because the fossil fuels are getting depleted fast and we need to turn to alternative energy sources to meet all our requirements.
Transforming the raw fossil fuels into petroleum and other products included complicated processes such as refining and other processes. These processes are extremely expensive and need a lot of hard work as well. Since we have accomplished such as difficult task in the last century, it won’t really be that tough to harness the alternative energy sources.
Though migrating or shifting to a new source of energy may be an alien concept since we are so used to petroleum, the truth is that it is essential for the progress and health of our planet. This step will help us in controlling pollution, decrease global warming and even help us to continue living in the same kind of lifestyle that we have been used to.
Let’s take solar electricity and associated costs for an example. The apparatus that needs to be purchased to harness this kind of energy is naturally more costly than the electricity generated by conventional sources. However, we need to accept these kinds of expenses while we shift to the renewable sources of energy. Nothing is going to happen overnight. We all need to bear the changes and expenses associated with the transition.
The process to generate electricity is actually not different from how electricity was discovered centuries ago by Michael Faraday, a British scientist. Electromagnetic induction is the most common method of transforming kinetic energy into electricity. There are six more methods aside from this, but working on all of these requires skills and knowledge to be able to develop a renewed energy that will benefit all of us.
The progress of photovoltaic technology has really been fast in the last few years. However, the problem still remains that mechanical power is still cheaper than the photovoltaic solar panels. There has been a 40% enhancement in the capacity in places like New Jersey, California, Japan and Germany. It’s been predicted that in the coming year’s solar power will become more practical than petroleum with the new innovations in the market.
New power sources can be created but we need to understand the mistakes of the past and even know about the emerging methods and products. These days, students are being taught about the negative effects of pollution and the value of the earth, sun and the wind. The faster we develop new inexhaustible and non polluting sources of energy for the inhabitants of planet earth, the better it is!
