 * __Experiment #1__**

__Problem Statement__- Does the air temperature affect the amount of static electricity generated? __Hypothesis__- If the air temperature is being tested, then the most static electricity will be generated at an air temperature of 79 Degrees Celcius. __Independent Variable__- The air temperature.

__Dependent Variable__- The amount of static electricity generated.

__Controlled Variables__-
 * 1) Type of material
 * 2) Amount of time rubbing
 * 3) Type of carpet
 * 4) Power of rubbing
 * 5) Person rubbing

__Materials__-
 * 3 Balloons
 * Carpet
 * Timer
 * Hole Puncher
 * 3 Sheets of Paper

__Data__-
 * **Type of Material** || **Air Temperature** || **Pieces of Paper Picked Up** ||
 * Balloon || 73 Degrees || 6 ||
 * Balloon || 76 Degrees || 3 ||
 * Balloon || 79Degrees || 5 ||

__Results__- After 3 trials, I have seen that only dramatic changes were between 73 Degrees and 76 Degrees. Go on to the next subtitle to see if my hypothesis was accepted or rejected.

__Conclusion__- The results and data have shown that my hypothesis was rejected. From this experiment, I have learned that the air temperature does not change the amount of static electricity generated that much

__** Experiment #2 **__ __Problem Statement__- Will the amount of time rubbing a material against a carpet affect the amount if static electricity generated?

__Hypothesis__- If the amount of time is being tested, then 2.5 minutes will generate the most electricity.

__Result__- After 3 trials, the only dramatic changes in my data were between 2 and 2.5 minutes. In the next subtitle, I will say if my hypothesis was accepted or rejected.

__Conclusion__- Results have shown me that my hypothesis was accepted. The amount of time you rub the material //does// affect the amount of static electricity generated.

__RESEARCH PAPER – “DON’T GET //TOO//__ __CLINGY!"__

=Introduction-= As you all know, the science fair is coming up this month and this will be my research paper. What my science project topic will be on is //static electricity.// Included in this research paper will be topics related to static electricity like //static electricity//, //electric// __Y!”__ //induction, electrons, electric charges, and tools to measure static electricity.// When you are done reading this paper, you will probably know everything that has to do with, **//static electricity!//**

=Static Electricity-= = = “What is static electricity ?”,you might ask. Static electricity refers to the building of electric charge on an object(s). The static charges stay on an object until they either bleed off to ground or are quickly destroyed by a discharge. Static electricity can be differentiated with current (or dynamic) electricity, which can be delivered through wires as a power source. Although charge exchanges can happen whenever any 2 surfaces come into contact and separate, a static charge only stays when at least 1 of the surfaces has a high resistance to an electrical current (an electrical insulator). The aftermath of static electricity are similar to most people because people can feel, hear, and even see the spark as the leftover charge is destroyed when brought close to a large electrical conductor (for example, a path to ground), or a region with a leftover charge of the opposing polarity, (positive or negative). The similar experience a static “shock” is caused by the destruction of charge. Some examples of static electricity is when you go down a slide and you hear pops and crackles. When you come out, your hair might be standing on end. Another example is when you see lightning come out of a cloud. Lightning is an example of a natural static discharge.” Over everything, just remember that when you see lightning strike, say that it is related to “**//STATIC ELECTRICITY!”//** =Electrostatic Induction= Electrostatic induction is a redistribution of electrical charge in an object, caused by the influence of close –by charges. Induction was made thought of by British scientist John Canton in 1753 and Swedish professor Johan Carl Wilcke in 1762. Electrostatic generators, such as the Wimshurst machine, the Van de Graaf generator and the electrophorus, use this concept. Electrostatic induction should not be confused with electromagnetic induction (because both are often related to “induction”. One thing to remember about this part of my research paper is to never confuse electrostatic induction with electromagnetic induction. =Electrons= The electron is a subatomic particle with a negative elementary electric charge. It has no known components or understructure; in other means, it is generally thought to be an elementary particle. An electron has a mass that is exactly 1/1836 that of the proton. The design of the angular momentum (spin) of the electron is a half-integer value in units of //h//, which means that it is a fermion. The antiparticle of the electron is called the positron; it is similar to the electron except that it carries electrical and other charges of the opposite sign. When an electron crashes with a positron, both particles may either scatter off each other or be totally destroyed, producing a pair (or more) of gamma ray photons. Electrons, which belong to the first generation of the lepton particle family, participate in gravitational, electromagnetic, and weak interactions. On top of all, remember to never collide a electron with a positron, because if you did, you might be exposed to gamma rays. =Tools To Measure Static Electricity= This section is not made due to information not found on this topic. (Sorry Mr.Hankins! I couldn’t find any information on this topic!) =Electric Charges= Electric charge is a physical property of matter that causes it to experience a force when close to other electrically charged matter. Electric charge comes in two types, referred to positive and negative. Two positively charged objects experience an attractive force. The SI unit of electric charge is the coulomb (C), although in electrical engineering it is also related to the useof the ampere-hour (Ah). The study of how charged objects interact is classical electrodynamics, which is accurate in (as far)as quantum effects can be ignored. The electrical charge is a fundamental kept property of some subatomic particles, which determines their electromagnetic interaction. Electrically charged objectsare influenced by, and produces, electromagnetic fields. The interaction between a moving charge and an electromagnetic field is the source of the electromagnetic force, which is one of the four fundamental forces. =Conclusion= Whether it is electric induction, electrons, electric charges, or static electricity, they all have one thing in common, they all have to do with STATIC ELECTRICITY!

__Problem Statement__- If I rub a piece of aluminum foil on a carpet for 1 minute and a piece of cloth for another minute and a balloon for another minute, then which material will generate more static electricity?

__Hypothesis__- If I rub the carpet with a piece of cloth, then it will generate the most electricity.

__Independent Variable__- The type of material.

__Dependent Variable__- Amount of static electricity generated.

__Controlled Variables__-


 * Amount of time to rub the material against the carpet.
 * The type of material the carpet is made of.
 * The temperature of the air.
 * The place where the experiment takes place.
 * The amount of speed I rub the material against the carpet.

Tell me, what do you think of when you hear the word //science//? You would probably think of Isaac Newton, Albert Einstein, and astronomer Galilleo Galille (sorry, it's hard to spell his name). Science is everywhere. When you see steam coming out of your mom's teapot, thats science. When you see your dad blowing up a balloon for a birthday party, thats science. Science is the study of the natural world. Scientist use many types of procedures from science. All of these procedures include predicting, inferring, observing, scientific investigations, making models and more. In chapter 1 lesson 1 of the interactive science textbook it describes a marine biologist named Dr.Earl that has spent most of her life underwater studying marine sealife. Dr.Earl does many experiments and procedures like listnening to the "songs" of the humpback whales when the whales are at different moods and see how they behave. So my point is that no matter where you look, there is science going on. This is my report on the meaning of science.

__ABOUT ME__

Some of my interests is playing basketball and football. One of my favorite subjects is P.E. because you can go outside and have fun and at the same time stay healthy. My favorite topics in Science would be weather, space, and plants. But if I had to pick one out of the three, it would be space. One of my greatest dreams was to be an astronaut and be launched into space. My least favorite topics in Science would be cells, chemicals, and erosion. My most least favorite topic is cells. All the types of cells and parts of cells just confuse me a lot and give me a big headache.
