How did the great invention of the 20th Century come about and who is Tim Buerners-Lee, the English scientist who passed his great invention on to humanity?

When looking for cool science fair projects, one popular category is to show how science can help solve the problems that we are facing globally today. There are several experiments that you can do to suggest solutions that we as individuals can effect by making changes on a personal basis.

? Experts are saying that the amount of food and items that can be recycled going to landfills are at an all-time high. To promote composting and recycling you can do the following:

(1) Find a home that does not currently recycle or compost and count the number of garbage bags that are put out each week for pick up.

(2) Learn about what items can be composted or recycled and educate the owner as to what food items and recyclables can be taken out of the garbage instead of going into the landfill.

(3) Get the owner to agree to compost food items and recycle things rather than throwing them out. Provide a small garbage can to put the items to be composted into and show them how to compost properly. Wash and recycle those items that can be.

(4) After three weeks’ time, count the number of garbage bags going out for garbage pickup. Quantify the savings and multiply that by the number of households in your community to show how much can be saved on a yearly basis.

? The use of disposable diapers is clogging modern landfills at an alarming rate. Experts are estimating that it will take hundreds, if not thousands, of years to decompose.

(1) Research the alternatives that there are to the use of disposable diapers.

(2) Compare the savings to the environment if the use of disposable diapers are reduced significantly (like only using them at night rather than all of the time.

(3) One area not traditionally addressed is the use of adult briefs by those who are disabled or in places such as nursing homes. Are there alternatives available for this segment of the population? If not, why not?

? In June of 2009, President Obama signed into law legislation to promote the use of renewable energy sources like the wind and sun by offering financial incentives to homeowners and businesses that install individual generators and hook into a local power grid to sell any overage in wattage that they produce.

(1) Find out which generation is more effective in each part of the country based on the average wind or sunshine amounts received,

(2) Learn about what things are needed to have either a wind or solar power generation system. Explain in detail what each system does to generate electrical power.

(3) How can the use of these renewable energy sources prove to be a help to conserving the environment (for example, the vast majority of electricity generated in the US comes through burning coal at commercial utility plants, rather than through hydro sources as some may think)?

As you can see, there are a great number of cool science fair projects that you can come up with. All you need is a little imagination, and you could have yourself a real winner.

iPosture is a little gadget that you attach to your clothing to let you know when you’re slouching. It’s the kind of product which cowboys and gangstas must hate of course, but that’s a story for another day. The device works by vibrating when it senses that you’re slumped over, thereby telling you to sit up straight and finish off your greens or you’ll be for the high jump young lady. Or something like that. $64.95.

 The iPosture is an intuitive electronic device designed to improve posture. Just over one inch in diameter, the iPosture automatically senses when the body slouches, and it alerts the user with brief vibrations to correct it.

For a playground, everything begins with the installation. The life and use of playgrounds are directly dependent on how well they have been designed and installed.

Planning ahead is one of the most important steps when it comes to installation of playgrounds. Advanced and detailed planning is the only way to ensure that there is enough space and proper positioning for every piece of equipment.

The first step is to determine the dimensions and size of the playground area so that it can accommodate all the desired elements. There must also be a safe zone that acts as a border between the equipment and the peripheries of the playground.

Geography also plays an important role. The local soil type, topography and rainfall amounts must also be taken into consideration before installing playgrounds in an area. These factors play a big role in deciding the drainage system of the playground.

To help limit the number of injuries sustained in playgrounds, it is important that professionals building playgrounds should stick to the building guidelines that have been laid down by the ASTM (American Society of Testing and Materials) and ADA (Americans with Disabilities Act). This means that playgrounds must have equipment that is easily accessible and available to disabled children.

Certain playground surfaces are certified as being safe. These include rubber and wood fiber. By providing a surface that has high cushioning thickness and shock absorbency, children are ensured maximum safety in case of falls. Shredded rubber is one such surface. Unsuitable surfaces account for 80% of all playground related injuries. So, the choice of the surface for play area is almost as important as the elements used within the playground.

While choosing equipment, three important factors decide the how playgrounds eventually turn out to be:

-         Safety

-         Durability

-         Budget

These days, playgrounds have much more than a few metal slides and plastic swings. In fact, there has been a revolutionary change in the quality, materials, colors and options available. The variety of elements that may be used in playgrounds is vast. While choosing these elements, it is important to consider safety and usability.

Generally, longevity is not an issue with play elements available today. Playgrounds are installed for a very large period of time. Unless there are instances of vandalism or some natural calamities, playgrounds should last for more than 20 years. Many parts like clamps and poles have lifetime warranties; others have warranties spanning 10 years or more. So, there really is no reason to dismantle a playground unless it is a desire for something new or fresh.

This is the reason why playgrounds are designed by trained professionals. Professionals are trained to look at the larger picture without losing sight of the smaller details. For instance, they can easily design a roomy playground that can accommodate the best elements but they will also remember to consider the needs of elderly people visiting the playground.
