Science is very important to the world because it shows us more about the world and the surroundings. The processes of science are observing,inferring,predicting, classifying,making models,evaluating,and investigating. Now i'm explaining all the processes.The first is observation ,it mean to use one or more of your senses to gather information,its mostly used for science processes. There are two ways to observe ,quantitative and qualitative. Quatitative is numbers and amounts. Qualitative means with discription and can not be expressed in numbers. Next is inferring it means making an educational guess.Then is predicting it means to make a statement or a claim about what will happen in the future based on past experience or evidence. The next word is classifying it means grouping together of items that are alike in some ways.Next is evaluating involves comparing observations and data to reach a conclusion about them. Then its making models involves creating representations of complex objects or processes. Finally its investigation it means the way in which scientist study the natural world .=

= static electricity- = Static electricity is the build - up of electric change on a surface of an object. Static charge remain on a object until they bleed off to ground or are quickly neutralized by discharge. Static electricity may be contrasted with current electricity, which can be given through wires as a power source. The effects of static electricity are familiar to most people can feel, hear , and see a spark the excess charge is attracted when brought close to a large electrical conductor. The well known phenomenon of a static " shock " is caused by the neutralization of charge. Materials are made of atoms and molecules are normally electrically neutral cause they have an equal number of positive charges.

= electromagnetic induction - =

Electromagnetic induction is the production of electric currents across a conductor moving in a magnetic field. It underlies the operation of generators, transformers ,induction , induction motors , electric motors , synchronous motors , and solenoids. Michael Faraday is credited with the discovery of induction in the year of 1831 it have been anticipated by the work of Francessco Zantedeschi in the year of 1830 to 1832. A gentleman named Joseph Henry made a similar discovery but didn't publish his discovery later.

= Force- =

In physics ,force is any influence that causes an object to undergo a change in speed a change in direction or a change in a shape. Force is also known as intuitive concepts such as a push or pull that can cause an object with mass to change velocity.

= Electrons - =

An electron is a subatomic particle with negative elementary electric charge. No known components or substructure. An electron has a mass that is approximately 1/1836 that compared to a proton. The intrinsic angular momentum of the electron is half integer value in units n, means it is a fermion. A antiparticle of a electron is called the position it is the same to the photons. Electrons which belong to 1st generation of lepton particle family.

= Summary- =

Static electricity is the build up of electric change in a surface. Electrons are a part of electricity because it is a subatomic particle with negative elementary electric charge. Electromagnetic induction is the production of electric currents across a conductor moving in a magnetic field. Force is another thing involved with static electricity, it has two meanings. In physics it's any influence that causes an object to undergo a change in speed, direction , and shape. The other meaning is push or pull that can cause an object to change. =

VARIABLES- = independent -changes =

= Experiment 1- =

= Problem Statement - = = Which material can be charged with static electircity. = = = Hypothesis - If plastic is charged by static electricity then a piece of thread will be charged by static electricity.

Materials- 1. 3 plastic spoons 2. 3 pieces of plastic bag 3. 3 pieces of thread 4. 3 pieces of notebook paper

Produces - 1. separate the materials away from one another. 2. grab the spoon and get one of each materials. 3. rub the spoon against one of the materials and watch if it got static electricity. 4. do # 3 with the other materials left. 5. 2 trials more the same thing. 6. graph it.

Variables-

Independent - amount of static electricity

Dependent - 1. The materials. 2. The shape of the materials. 3. Physical and chemical way of the materials.

Controlled variables - 1.the plastic spoon 2.the plastic 3.paper 4.thread 5.the surface im doing the project on.

= graph counted by 5 to 30 seconds of the spoon being rubed on the materials. =

= = Experiment 2- =

Problem Statement - How much time does static electricty last with specific materials.

Hypothesis - If I use paper towel and plastic rapper from Kit Kat chocolate and time it then i think it will last less than 7 seconds.

Materials - 1.plastic spoon 2.3 pieces of cut paper towel 3.3 pieces of Kit Kat plastic rapper 4. timer

Produres - 1.separate the materials. 2.grab the spoon and rub it against the towel papers. 3.lift the spoon. 4.have a spear person to help start and end the timer. 5.3 trials. 6.do the same to the Kit Kat rappers. 7.3 trials. 8.graph it.

Variables- independent - 1.the time the paper towel or the rappers stay on the spoon.

Dependent - 1.the materials 2.the shape of the material 3.the physical and chemical way of the materials

= = Conlusion- What i hypothesized was wrong the kit kat rapper and the paper towel lasted longer than what I had expected.
 * material || trial1 || trial2 || trial3 ||

Experiment 3 - =

Problem Statement - Can static electricity charge different kinds of flower pedels.

Hypothesis - If I use flower pedels then i think they will be charged by static electricity.

Materials - 1.red rose pedels 2. purple orkids pedels 3.plastic spoon

Produces - 1.separate the materials 2.rub the spoon gently on the pedle 3. move the spoon gently and slowly to see if there was any electricity going on 4.do the same to the other pedels 5.3 trials for both pedels 6.graph it

Variables - independent - the movement of the pedels in inches

Dependent - the materials it is measured by inches
 * = pedels = || trial1 || trial2 || trial3 ||
 * = red rose = || 6in. || 3in. || 7in. ||
