Character development keeps an audience interested. Being able to pull emotion out of the main character allows the audience to feel the pain or excitement that is being portrayed. In director Atom Egoyan's "The Sweet Hereafter," Dolores Driscoll brings out the sadness that her character is feeling. You can sense the pain and distress that she bears. Yet, in the novel, The Sweet Hereafter, by Russell Banks', Dolores does not grow as a character. The audience never deciphers if Dolores understands
Investigating How Length and Width of Copper Wire Affect the Current of a Circuit Task: To investigate how length and width of copper wire affect on the current of a circuit. Prediction: In this experiment, the input variable will be changing the length of the copper wire used in the experiment, and also the SWG of the wire, which means the width of the wire. By changing this variable, the current the circuit will vary. With my knowledge in science and some
Did you know that a spark of electricity can measure up to 3,000 volts? Electricity is all around us. It powers cars, computers, cell phones, television sets, stoves, air conditioners, and gives us light. What is electricity? A simple definition would be a type of energy that can build up in one place or flow from one place to another, or the flow of charged atomic particles. It is a movement of charged atomic particles, called electrons, protons, and neutrons. The two main forms of electricity are
In polar covalent electrons are not shared equally because one atom spends more time with the electrons than the atom. Polar covalent create a dipole-dipole intermolecular. The force can create type of bond between polar molecules as well as hydrogen bond. This bond is not as strong as the other types of bond and it can be easily broken.
Study case on Photons Detectors using LED, Infrared, Pin photodiode and avalanche photo diode The term photon means “visible-light particle”, is define as the fundamental particle of visible light. Isaac Newton was among the first scientists to say that light consists of particles; Photons moves through empty space at approximately 299,792 Km/s. However Infrared rays, visible light, Radio waves, Ultraviolet and X-rays Particular that contains an amount of Energy that depends on the wavelength consist
it couldn’t be a chemical change. Chemical changes happen on a very small scale and can happen over a period of time. Chemical changes are a change that forms a new chemical substance. A chemical changes is the breaking or joining of bonds and atoms. Iron rusting, gasoline burning, and milk souring are all chemical changes because new substances are formed. Boiling water, dissolving sugar, and dicing potatoes are examples of physical changes because nothing is changed but the appearance of the
Neutralisation - How much acid is required to neutralise a base Introduction ============ Neutralisation is the reaction of a base with an acid to form a neutral solution; which contains salt and water. Acid + Base Salt + Water --------------------------- In my experiment I am trying to find out how much acid it takes to neutralise a base to form a neutral solution. I will use one molar of Nitric Acid as the acid and one molar of Ammonium Hydroxide as the base. So this will be a 1:1 ratio. (Molarity
Dark matter has been argued about for a long time about whether it helps or not helps the universe. The universe is mostly made up of dark energy at 71.4%, dark matter at 24%, and atoms a 4.6%. These are the statistics made about the composition of the universe. However, these statistics were not always none. Einstein himself said that the universe was static, that the universe was neither contracting or expanding. When the Russian Mathematician, Edwin Powell Hubble, proved him wrong, Einstein said
One of the least spoken about elements, cerium, is important and rather abundant for being considered a rare metal. It is more abundant than most metals in Earth’s crust. Cerium (Ce) has an atomic number of 58 and an average atomic mass of 140.116. To find it on the Periodic Table, either find atomic number 58 or use the electron configuration of [Xe]6s24f15d1. When searching across The Periodic Table, cerium is not a definitive eye catcher, however, seeing pure cerium ignite when scratched will
In this experiment, we computationally predicted the dipole moments of 5 different analyte molecules using the program Spartan. We constructed the molecules online as the program then calculated their dipole moments (polarity). We then experimentally determined the 5 analyte molecules retention factors using the TLC method in the lab. Polarity in organic chemistry refers to a separation of electric charge leading to a molecule having an electric dipole moment1. To determine whether a molecule is
Thoroughly describe the electron movement in a single covalent bond. This occurs when two atoms share electrons, and both will circle the atomic nuclei. 15. Name the four macromolecules that are found in all living organisms. All living organisms contain at least four types of macromolecules which are proteins, carbohydrates, lipids and nucleic
differentiation of wholeness. The defined structure may be seen as circular in two respects: On the one hand it is the precondition for the understanding of its own syntactic and semantic basics, on the other hand there exists a mutual defineability between its atoms, which leads us to the thesis that wholeness cannot be defined in a non-circular manner. Introduction In this paper I attempt both to explicate the popular, but vague notion of wholeness and to point out its meaning for ontology. To begin with

ozone hole forming above the Arctic region.1 Ozone gas contains an extraneous oxygen atom in each molecule and is highly unstable. This property lets ozone block out ultraviolet rays and makes it an essential part of the eco-system. When harmful ultraviolet-B rays (wavelength 240-320 NM) come through the atmosphere, the O3 molecules absorb the energy and one oxygen atom detaches from the molecule. The stray atom will eventually collide with another O2 molecule and ozone will be reformed. With this
matter exists in the form of atoms, which move around the universe in an empty space. This empty space, or vacuity, allows for the movement of the atoms and without it everything would be one mass. He explains that matter and vacuity can not occupy the same space, "...where there is empty space, there matter is not...", and these two things make up the entire universe. These invisible particles come together to form material objects, you and I are made of the same atoms as a chair or a tree. When
two types. The first could be ionic, where a metal is produced. Ionic bonding involves electrons transferring from one atom to the other consequently leaving an electrostatic force between them. The other form of bonding is covalent where atoms share electrons to complete their outer orbit. An example being Methane where four hydrogen atoms each share an electron with a carbon atom.

exothermic reaction which produces a brilliant flash and a loud report from the rapidly expanding gases produced. For a color effect, an element with a colored emission spectrum is included. Electrons in atoms can be raised to higher-energy orbitals when the atoms absorb energy. The excited atoms can then release this excess energy by emitting light of specific wavelengths, often in the visible region. In fireworks, the energy to excite the electrons comes from the reaction between the oxidizer
scale. Some of which are still in use today. In 1841 the chalkboard was introduced into the classroom. This was very beneficial to learning integrating audio and visual techniques to learning. Teachers could now draw for students concepts such as atoms and molecules, that were complicated to express. Students found this invention beneficial because now the student knew what teachers were saying, what key points they needed to know were, and nothing was lost in the communication. The inclusion

Introduction Carbon exists in different forms such as graphite, amorphous carbon, and diamond, among others. Its graphitic carbon has a hexagonal and crystalline structure that easily cleaves which in turn makes it a soft material and effective lubricant. Its widely occurrence in earth’s crust makes it one the most abundant elements. Carbon presents itself in different allotropes such as Graphene, fullerenes and carbon nanotubes. Some of these allotropes have proven to be conducting and others to
