Will the balloon racer go farther with or without weight?

Hypothesis If I add various weight to the middle of the balloon racer, then it will move farther than a car without weight. Problem Will the balloon racer go farther with or without weight? The following is the procedure used to make my car: Materials for Balloon Car Racer: Piece of cardboard 1 rubber band 1 balloon 4 wheels 2 non-flexible straws 1 flexible straw Tape Step 1 : Cut a piece of cardboard measuring 8” x 6”. Decide which side is going to be the top and which one is the bottom. Step 2 : On the bottom side of the cardboard, place two straws (without a flexible center) about 1” from the front and back of the cardboard. Step 3 : Insert a dowel rod, smaller than the straw, inside the straw. This will be the axle rod of the car. Step 4 : Place four wheels (I used wooden, premade wheels), on the ends of the dowel rod. Step 5: Tape ends of dowel rod so wheel won’t fall off. Step 6 : Take a straw with a flexible midd

Your Sight and Heartbeat are connected ?

Purpose I want to find out if your heartbeat will respond more to a vibrant color or dull color Materials First of all you are going to need some materials. • Stop watch • Different variety of color paper • 3 people • Paper • Pencil Get ready to find out the truth behind the heartbeat… Hypothesis In my personal opinion I think people’s heart beat will be faster with vibrant colors (yellow, red, and blue) while with dull colors (gray) your heartbeat will be slower. I think this because your eyesight would be alarmed with more alerting colors than boring colors which will affect your heartbeat. Procedure Ok now we are going to perform this experiment. Make sure you know what your materials are. 1. Take your three people and make one stare at a vibrant color (yellow, red, blue) for 60 seconds. 2. Take his pulse for one whole minute. 3. Write it down (don’t forget it). 4. Then take the same person and make him stare at a

How to Make a Balloon Dog ?

When you were a kid, do you remember having birthday parties with clowns and magic? There were balloon animals and the clowns were experts in making them and the kids were enthralled. It was a magical moment, getting to see a hotdog shaped balloon turning into an animal. Making a balloon dog takes practice. Like any craft, it should be practiced and mastered to be a success. To make one, one should have a long skinny balloon. It is called the 260Q-type of balloon. Blow it. You can use a hand pump or football pump to blow the balloon. Leave at least 1 1/2 inch of deflated balloon. Tie this end. Make a twist at the end of this balloon, two inches from the knotted end. Then make two more twists, one inch apart from each other. Hold the balloon well, do not let go. This will ensure that the balloon will not untwist itself. The technique when twisting a balloon is to twist the balloon in the same direction, with two or three turns. Twist the smaller balloon bubbles together,

How do oil spills affect aquatic plants?

Topic Information : Effects of oil spills This science fair project was performed to find out how oil spills will affect aquatic plants. Testing was done using hydrilla plants in water with and without a layer of oil covering the surface. Oil is an organic fluid that has a lower density than water. When oil is spilled on water, it will float on the water surface and form a thin layer. Oil is not soluble in water. This thin layer of oil on the water surface is called sheen and it can kill the aquatic animals and plants that live beneath the water if it is not removed quickly. The presence of oil on the water surface will blocks sunlight and prevents air from reaching the plants that live in the water. This will prevent the plants from producing food through photosynthesis. Without photosynthesis, the plants will not be able to grow, germinate and produce oxygen. If this condition persists, the plants will eventually die. Aquatic animals are also not spared by oil sp

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:

Make a Sundial

Shadow sticks or obelisks are simple sundials. If the sun rose and set at the same time and spot on the horizon every day, they would be fairly accurate clocks. However, the sun's path through the sky changes every day because the earth's axis is tilted. On earth's yearly trip around the sun the North Pole is tilted toward the sun half of the time and away from the sun the other half. This means the shadows cast by the sun change from day to day. Sundials only measure local solar time. If a friend had a sundial 5 degrees longitude to the west of your sundial, his sundial would read a different time than yours. This is a simple calculation: the earth turns 360 degrees in about 24 hours, therefore the sun's apparent position moves 360/24 = 15 degrees each hour. So your friend's sundial would read 20 minutes different (earlier) than yours. This difference is only affected by longitude, not latitude. To standardize things, the earth was divided into 24 time zo

Make a Radio

Do you have a transistor radio at home? No? A Transistor radio is great fun; you can listen to music or news almost anywhere. Do you know what a transistor radio is? A transistor radio (or transistor) is a small, often handheld, radio receiver. You can buy a transistor radio these days for as little as Rs. 50. The transistor radios sold in the market require an external power source -- electricity from the mains or from a dry penlight cell. You can make a transistor radio that does not require any form of electrical source to operate. All you need is a few electrical/electronic components. These should be easy to get provided you have some electronic repair shop or a shop that deals in electronic components. The components that you will need and how to get them are described below. You will need several meters of something called enameled wire. Enameled wire is copper wire, coated with dark colored enamel paint. It's thickness is measured in ‘gauge’. What

Make an Electroscope

An electroscope is a device that is used to demonstrate properties of static electricity. Static electricity is a phenomenon that takes many forms. It can be an electric shock you can get after walking over a carpet, or it can be a lightning bolt from the sky. The electroscope demonstrates the repulsive force that is exerted between two nearby objects with the same electric charge. In this activity you will learn to make your own electroscope. You won't need any exotic materials for this activity, all that is needed is readily available and can even be found in your house. First of all you must brush-up your knowledge about static electricity. The following links can help to a large extent; they have been listed according to their level of presentation: To make an electroscope all you need is listed below: 1. An empty glass jar such as a jam jar. 2. A length of stiff copper wire about 12 cm long (or a large steel paper clip). 3. A sheet of aluminum kitchen f

Make a Stethoscope

A stethoscope is an instrument used by doctors to hear sounds generated from within human body. They are used to listen to the heart, lungs and intestinal tract. They are also used for measuring blood pressure. If you dream to be a doctor one day this activity will interest you a lot. You can make simple stethoscope very easily. But first of all you must learn a bit about it. Visit the following website and you will find all the details about a stethoscope in a language that you can follow easily. You may also be interested to know, when and who made the first stethoscope, and how its design has evolved ever since. The following website gives an exhaustive information about all this: A stethoscope as you would now know, is based on the principle of collecting sound waves from a particular area, and transferring them to the ears of its user through a pipe/s. Thus to make a stethoscope you would need something to collect sound waves (like the bell of a doctor's stethos

Make a Telescope

You must have heard about telescopes. If you are lucky you might have even seen one. A telescope is an instrument to view distant celestial objects, like the Moon, planets etc. Common telescope are called optical telescopes. They come in two varieties: refractors and reflectors. In refracting telescope (refractors), the optical system consists of lenses. Both the Objective (the optical system at the front end of the telescope) and the eyepiece (the optical system used to look through the telescope) are lenses. In the reflecting telescopes the objective is a parabolic mirror and the eyepiece is made of lenses. The telescopes used by astronomers are often huge and cannot be constructed very easily. Often the most difficult job when a young enthusiast decides to make a telescope is to find lenses or mirrors. But we have found a design that is suitable for most young students in India. Parabolic mirrors for a reflecting telescope must be ground, which is rather arduous and time cons

Make a Periscope

Are you familiar with the word "submarine"? A submarine is a kind of boat that moves underwater. Submarines are common crafts for the Naval forces of any country. But, while moving underwater, submarines need to know where they are with respect to other objects on the surface of water. The device they use to do this is called a periscope. Periscopes are optical instruments that can afford submariners a limited though vital visual picture outside their windowless hull. Traditionally, periscopes offered the submerged submarine its only glimpse of the outside world. Classic English war movies have also made them the submarine's most familiar feature. For most of us, who are unlikely to come across submarines in real life, a periscope can make it possible to see round corners and over the heads of crowds during processions or at sporting occasions. In a periscope, two mirrors are arranged at 45 degrees to each other. One mirror captures the rays of light from t

Make a Camera

Cameras have become a standard item in many households. You must have seen a camera somewhere, sometime. But do you know, what is a camera? What is inside it? How does it take photographs? The most basic type of camera is the pinhole camera, which one can construct from a cigar box, aluminum foil, and sheet film. In this activity, we'll learn how to make a simple pinhole camera (we call it a pinhole scope) and how it works. A pinhole camera does not have a viewfinder; neither does it have any control of aperture or shutter time. One has to do them manually. But it cost so little. The major difficulty is in fixing the photographic paper/film and developing it. If you think your circumstances do not permit you to experiment with photographic paper or film, you can still see how the image is formed in such a camera. A very simple description to make such a pinhole camera is provided at the following website, (don't be put off by the brand name of the container
