Solar cooker, solar race car, solar battery charger, solar radio, and solar generator are some of the good project ideas that can be an interesting science fair project.

A good topic for a science fair project is about the solar energy. It is also an interesting and popular topic because solar energy can be of great importance in our everyday activities. Utilizing solar energy implies a great aid in our depleting fossil energy needs. Developing technology using solar energy is very helpful in promoting an unpolluted environment. Here are some solar energy science fair project ideas that can be further develop as a promising energy alternative.

Solar cooker

Solar cookers are one of the most simple and popular science fair projects. It is a simple demonstration of using the sun’s heat to cook food. It is a good science fair project because it can be easily built and is very effective in conserving electricity. Most solar cookers have the same idea with that of a solar oven. You can create any dimension of size and shape of solar cookers to add an interesting look on the project.

Solar race car

Building a solar race car is also a good and fun science fair project. It is just like creating a home made toy car and learning the concepts of solar energy at the same time. To build a solar race car one can be creative in approaching a design. The energy source mechanism will show how a solar energy panel can produce power to make the race car run. It is a fun project for boys and students who love playing race cars.

Solar battery charger

Solar motor charger demonstrates how solar power can directly be used. With the help of solar panels, the sun’s heat will be transformed into electrical heat which can be used in charging batteries. It is a simple demonstration on the efficiency of light energy in providing alternative power source.

Solar radio

This application of solar energy will show how useful this energy source can be in places where no electricity is available. Solar radio can be created by simply turning an ordinary radio that works with electricity into a radio that uses the solar panel charged DC. Simply understand the radio’s electrical wiring and work your way in attaching the solar panel as the radio’s power source.

Solar generator

Using solar generator has been a popular choice for an environment friendly home. You could make a study in using solar generator as an alternate energy source for your house’s electricity. Your study can include finding the average numbers of sunny days needed to run your solar generator for your home’s energy consumption.

You can pick any from these good science fair project ideas to enhance your planning skills and learn something new. Always remember to have fun while learning.

Early exposure to science is critical because science knowledge is cumulative. Learning science requires a solid foundation of knowledge that can be built upon through further study and exploration. Children should be introduced to science at home as early as possible. Don’t make the mistake of thinking that your child learns all the science they need to know at school. The truth is science education in school is limited and the subject is not usually a high priority for educators. As parents, it is important that we share our knowledge with our children. Every day activities such as growing plants, cooking and caring for animals involve science. Take a look around and you will see that science is everywhere. Parents can choose to engage in scientific activities with their children when they are not in school to build scientific comprehension, encourage scientific exploration and foster a love for science and the pursuit of knowledge. There are aspects of science that are intellectually demanding, but often simple experiences produce insightful learning. To engage your children in science you need to introduce them to stimulating environments that provide opportunities for observing and discussing science. Zoos, nature centers, oceans, parks, yards and even kitchens are perfect educational environments. Children naturally learn through playful exploration. Educational DVDs, and toys provoke thought and develop skills. When children ask questions to satisfy their natural curiosity, it is an open opportunity to be seized by the parent.

For instance, if a child is fascinated by a light switch and wants to know how it turns the light on and off, inquire into the subject with your child. Find out why and how the switch works. Why does yeast make bread rise? How does a spider spin a web? Why do leaves fall? Why do the birds disappear in the winter?

Identify your child’s interests and encourage them. If a child develops an interest in rocks, study rocks, gems, mining and fossils and build on that curiosity moving on to fossil fuels, heat generation and environmental effects. You will find that one inquiry leads to another.

Fuel their natural curiosity. These activities should be challenging without being frustrating. Don’t force them to do things they are not interested in; rather, engage them in motivating activities that build desire for further exploration. Share your own science related interests and you will be amazed by the impact of genuine enthusiasm. Remember that discussion is a key component to developing scientific knowledge and uncovering additional areas of interest. Encourage your child to talk about their experiences, observations and interests. This discussion will help children to construct thoughts, to form concepts and to examine different relationships that are intermingled in their ideas.

Some simple activities that foster knowledge of and interest in science include: “Finding out how and why things work”, “Sharing ideas and knowledge”, “Making observations and writing or drawing those observations down”, “Making predictions and seeking answers”, “Starting collections -such as rocks or bugs- and observing similarities and differences”, “Figuring out what causes things to change”, “Having science parties with family and friends”, “Enrolling your child in classes or extra-curricular activities involving science”.

Your home, your environment and your surroundings are filled with opportunities to share science with your children. Through engaging their interests and encouraging their search for knowledge, you can ensure success in science!

Negotiations can seem as complex as physics, and in fact, people go to college to study the science of negotiating just as they would the laws of nature. At the same time, negotiation is like an ancient art form, some sort of Zen mental jujitsu. When neither the Zen nor the science works, though, no one wins.

Just ask any hockey fan out there. The recent lockout and cancellation of the 2004-2005 NHL season is a perfect example of poor negotiating. Both the players union and the league owners broke all of the rules when it came to brokering an agreement on player contracts. The result are hockey rinks across North America that are so quiet that you can hear a pin dropunfortunately, not a puck. In dollar terms, professional hockey is missing out on television contracts, advertising fees, and tons of ticket sales.

Of course, you wont lose billions in revenue if you fail at the latest negotiation at your favorite online classified or auction site. But you could let a treasure slip through your fingers. Success in deal making, on the other hand, could land you that rookie Bobby Orr card, signed Stanley Cup puck, or whatever other fantastic item youre bidding on.

Plus, proper negotiations and compromise can ensure that you get the item for its fair value, including a good price on shipping and taxes. This increases the profitability of the trade for both you and the seller. The deal gets closed without nasty disputes, blow-ups, or hip checks. And both of you are left to do business again in the future.

To score all of these benefits, and avoid your own mini lockout, follow these simple tips on negotiating that will net results at online classified sites. As youll see, victory isnt so much an exact science or a mystic sixth sense. Its more about simple know-how and common sense.

Warm up. Dont jump into a negotiation cold. Before you even face off with your opponent, figure out for yourself what would count as a victory. What do you exactly want out of the tradeand at what price?

Consider a truce. It may not even be worth dropping the puck at all. In other words, negotiations, like hockey games, can end in a loss for the home team, you. So weigh this risk before you start. If the item at hand is a dream buy, you may not want to endanger your purchase with a drawn-out negotiation.

Know when to pass. On the other hand, if the item is far from dreamyand youre pretty sure something better may come along lateryou could pass on negotiations. Or go for the score. Offer a lowball price. If you win, you wont be out too much, and if you lose, it wont leave a mark either. But be certain if you play this game. You could miss this opportunity without a guarantee of future prospects.

Know your enemy. Coaches and players spend hours before games watching films of their impending competition to study their tendencies. You need to take the same approach when it comes to making a deal. Try to read your opponents mind. What is his or her goals in the negotiation? Does he or she have any strengths that they can use against you? Are there any weaknesses that you can use against them?

You’ve probably heard of Neil Strauss and “The Game” and chances are you’ve caught an episode or two of VH1’s “The Pickup Artist”. If you’re into learning how to meet women then there are hundreds of guys out there peddling products that they claim will help make you successful in this area. The problem is, if you just memorize some stuff that you read in a book then there’s a big chance of you using it and having someone call you out. That’s because there’s plenty of guys out there using the same material. Another problem with just memorizing lines out of a book is that you aren’t congruent with it. When you say it, you’re not genuinely interested in what you’re saying, so you don’t give much emotion, expression, or passion to what you’re saying, and people won’t be interested at all, or they’ll just think you’re making stuff up. How do you combat this though? If you don’t think you have anything cool to say, and you’re worried about staling out, then how can you make your speech more exciting and involving without just copying some other guy and using his techniques? One secret is to learn the structure and the patterns behind exciting and emotive language. Ross Jeffries and his Speed Seduction products put a lot of stress on learning the structure and the techniques to make your language come alive, and draw people in. Here are some of the techniques and patterns behind Speed Seduction, some tips that you can go out and use right now to make your speech have a lot more impact.

Feelings: Think of how many feelings are out there of the top of your head. Passion, excitement, adventure, joy, happiness, sadness, longing, connection. One of the keys to making your speech more interesting is invoking a variety of feelings while you’re talking with someone. With guys, we tend to be more logical, and to not really invoke this kind of stuff, but you have to make it a point to. Talk about some amazing adventure you had, talk about what the feeling is like when you’re really connected with someone, talk about the passion you have in your life. Really get involved in your own stories and feelings, and see it in your mind as if you’re living the story again. In this way, the person talking with you will go on a kind of rollercoaster ride of emotions. That’s one of the main techniques of Speed Seduction is bringing up a variety of different feelings and emotions (connection, lust, fascination, safety).

Quotes: A while back, I saw this documentary on the Discovery Channel where jackals eat their own fecal matter and regurgitate it to their offspring. No, I never really saw a documentary about this, but the thing is that you can say some of the craziest things if you claim that you heard it somewhere, like from a newspaper, a documentary, a friend, etc. One of the big techniques of Speed Seduction and NLP is saying things in quotes, so that you can get away with saying more risque things.

Weasel Phrases: It sounds really slimey, but weasel phrases are essentially just phrases that lead someone to using their imagination and leading them into a certain state, or a way of feeling. Examples include phrases like “Have you ever…?” “What’s it like when you…?” “Can you remember a time…?” For instance, you couldn’t really go up to someone and say “You should feel excited and totally interested.” They’d look at you like you have a third head. Rather you could say, “I just went to this really interesting lecture. Have you ever heard someone speak and you feel totally fascinated by what they’re saying, and the rest of the room just disappears, and time just melts away?” You’re achieving that effect, but you’re doing it in a less obvious way.

Time Distortion: One of the best ideas to come from Speed Seduction, and something that’s being incorporated into a lot of new books on seduction, is the idea of “time distortion” or “future projection” or “future adventures projection” (there’s like a hundred names for the simplest concepts). The idea is that you can create an image of the two of you going out, having a great time, and just really build it up into some big event. You can be serious with this, or you can be totally out there with this. MeHow advocates really wacky crazy stuff “We could be space aliens, and you could get in my spaceship and we’d fly back to my home planet and collect moonrocks” and Speed Seduction is more of a realistic approach “going out with someone and just having an amazing time.” If you really describe a date or event, go into details about how it’s the best thing since sliced bread, then the girl you’re talking to will be more likely to go with you. It’s a lot better to ask someone to go out for a totally fun adventure than a cup of coffee or the number 3 special at Burger King.

Speed Seduction gets a lot of negative press for being manipulative, but really a lot of the techniques are just patterns of good speech that persuasive people use. And the good part about learning the patterns of persuasive speech rather than word-for-word scripts is that you’re not going to get called out for something someone has already heard before. Plus, you can make things up as you go, and talk about stuff which is actually interesting to you rather than regurgitating (that’s twice I’ve used that word, sorry) something that you’ve read somewhere. These are just some of the techniques that are discussed in Speed Seduction that you can go out and use today. Just try them out, have fun, and good luck.

Science and Technology surround us wherever we go and whatever we do. From the way we communicate to the way we entertain ourselves, we all interact with it on a daily if not hourly basis. But, if you’re not already in the industry and didn’t grow up with an ipod or get an HTC for your 10th birthday, is it still possible to take a course in science or technology? Or have you simply missed the hi-tech boat?

Many people start studying at University directly after high school without a real idea of what they want to do with the rest of their lives, alternatively they start working immediately and get caught in the cycle of earning an income to meet expenses very early on in life. Either way, many people reach a point in their late twenties or early thirties, where after ten years of hard work they feel they have achieved what they wanted in their selected field of study or work and start craving a new challenge. And it doesn’t get much newer of much more challenging than the ever evolving field of science and technology courses.

To clarify, the field of science and technology is as broad and as all encompassing as the field of ‘art’. Except, instead of paintbrushes dueling it out with HDTV, science and technology courses more often go hand in hand. From scripting mobile phone applications to mapping the genome of the common housecat, revolutionary progress in one field inevitably has an indirect field on another and ultimately on the way we live our lives. Taking a course in science and technology therefore spans all aspects of modern living.

If you want to get involved with this constantly developing field, there are some questions you are going to have to ask yourself before setting out. It’s no coincidence that you can’t step into cyberspace without coming face to face with the work of a hundred good to great web designers, while the work of good to great bio-engineers is a little harder to come by. Before typing out your resignation letter and stapling it to your boss’s desk, ask yourself the following:

1. What career do I ultimately want to pursue? 2. How much time does it take to establish a career in this field without prior study/experience? 3. Do I have any cross over skills that I could transfer to a scientific or technological field? (Here’s a clue, project management is one of them, icing cakes is not) 4. Do I have the time to invest in skills acquisition part time? 5. Could I afford to invest in re-skilling full time?

Doing a quick budget or a ‘life audit’, where you break down how you spend your week on average hour by hour, will help you to decide whether you have the monetary or timing capacity to invest in a career change. But investing in a course in science and technology requires serious commitment and capacity and motivation are not one in the same.

Do as much research as you can into the science or technology course that you want to pursue and see if you can find someone in that field who can answer some of your questions. Better yet, ask them to allow you to shadow them for a day. Studies show that it takes at least 10 000 hours to become an expert at anything, so realise that you will need time to become proficient in your new career and above all, remember that it’s never too late to learn anything.
