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
