A Miniature Solar Panel

There are too many Americans using electricity. We may need to find another energy source to save fossil fuels for future generations. We are also polluting the earth causing global warming making the earth hot! We think that the solar panel will absorb heat causing the cold water to travel down the tube turning it into warm water. This is just as heat travels to turn into electricity. Purpose We would like to build a solar panel to help stop pollution to the ozone layer. It will also help the planet live longer in a clean ozone layer Materials Old newspapers Cardboard box about 30cm x 45cm x 15 to 20cm deep(12in x 18in x 6 to 8in) Sheet of cardboard Flat black spray paint Several meters or yards of black rubber tubing Large nail Black tape Plastic wrap Table 2 buckets Cold water Chair, bench, or stool Clothespin or larger paper clip Insulated cup thermometer Procedure First, crumpled newspaper along the bottom of a cardboard box th

Fire Water Balloon

Materials The materials required for this science fair project: - 1 matchbox - 1 candle - 1 yellow colored balloon - 1 blue colored balloon - Half a cup of water Procedure 1. For this experiment, the independent variable is whether the balloon is filled with water or not. The dependent variable is what happens to the balloon when it is placed above the lit candle. This is determined by observing the balloon. The constants (control variables) are how much the balloon is inflated and the amount of water in the balloon. 2. Inflate the yellow colored balloon and tie it up. 3. Pour half a cup of water into the blue colored balloon before inflating it to the same size as the yellow color balloon and tie it up. 4. Light up the candle. Be careful when using match sticks to avoid causing fires, or burning yourself. 5. Hold the yellow colored balloon on top of the lit candle. Observe and record what happens. 6. Hold the blue colored balloon on top of

Make Clouds in a Bottle

As you would know, a cloud is a visible aggregate of minute water or ice particles suspended in air. Clouds form when warm rising air and water vapor pools, cools, and condense. The possible reasons why this happens could be one or more of the following: (1) warming of the air at the earth's surface (convection) (2) air cooling as it expands, such as when wind encounters a mountain and moves up side (3) activity at a front or low pressure system (4) air expanding and cooling, such as when the rising air is exposed to lower pressure. However, cool air cannot support as much moisture as warm air. Therefore warm air that is rising will cool and reach a point whereby its relative humidity is 100%. It is at this point that moisture begins to condense onto the surface of particles in the atmosphere, such as tiny dust particles, soot, salt, and sulfate. These particles act as cloud condensation nuclei (CCN). This is all the background information needed, when you b

Secret Messages

We all are familiar with ink. It is the fluid inside a pen that allows us to communicate with others through written text. But, most often the communication is not exclusive, that is, anybody who can see the writing on the paper can in principle read the message written on it. Situations are possible when we would not like it to be so, that is when we want to communicate a secret written message. Is it possible? Definitely, science can make it possible. One can make an ink which instead of a dye solution (a coloured solution) has a colourless solution which can be made visible by some method. That is precisely the principle of invisible inks. An invisible ink is a solution which can be used to write with. The written message is either invisible on application or disappears quickly. It can be made visible by some means. The use of invisible ink is a form of steganography, and has been used by spies. The simplest invisible inks are organic compounds -- vinegar, lemon juic

Make a Rocket

Rockets are fascinating! They soar into the sky and help us know many secrets. Are you fascinated by rockets? If your answer is yes, you would be interested in this activity. The rockets that you can make safely will not go very far, perhaps much less then the rockets we enjoy on the Deepawali day. But then you will agree, the fun and excitement to make your own rocket has a totally different dimension. The basic principle of rocketry is Newton's Third Law of Motion, that is, "For every action there is an equal an opposite reaction". A big rocket uses chemicals to release an intense stream of gas out its tail end that propels it upwards. A fuel is used in a rocket to produce this gas through some chemical reaction. The rocket fuel is sometimes liquid, and sometimes solid. But, in all cases, a gas is ejected from the tail of the rocket. The first kind of rocket that we can make is propelled by a very safe gas - carbon dioxide. The fuel it uses is

Make a Hovercraft

A hovercraft is a vehicle which travels across land or water just above a cushion of air provided by a downward jet, as from its engines and propellers. It finds extensive uses for sports as well as military purposes. Commercial hovercraft can carry passengers, vehicles, and freight. Some can travel as fast as 130 km per hour. You can not definetly make such a vehicle, but you can make a model that illustrates its principle of operation. It's rather easy. All you need is a waste compact disk (CD) (The disks that are used to dispense computer software, games, music and films), a discarded PET bottle (the kind that is used to dispense soft drinks, cooking oil or drinking water), a big balloon and some adhesive. The method of construction is as follows: Cut the head of the PET bottle along with its cap with the help of a hot knife. Remove the plastic ring, if any, used for sealing. Fix the bottle cap in the center of the CD with the help of the adhesiv

Make an Anemometer

We have all felt the blowing of wind. Sometimes it is fast and sometimes gentle. Can you definitely assert that the speed of wind at a particular instant of time is more or less then at a different time? An anemometer is a device that can help you measure the speed of wind. You too can build is a model of an anemometer to measure the speed of wind yourself.. A real one will be able to accurately measure how fast the wind is blowing. Yours will give you only approximation of how fast it's blowing. It can't give you an exact wind speed. The energy in the moving wind can be used to generate electricity. But you have to know how fast the wind is blowing before you can harness wind power. All you need to make an anemometer model is: 4 disposable cups/glasses/bottles. They can be either the cups used for serving tea/coffee/ice cream, or tumblers used for dispensing softdrinks (e.g. fountain Pepsi), or bottles for dispensing drinking water. In addition you would need:
