Rules for Determining Significant Figures (digits) -All nonzero digits are significant figures -Counting begins from the left with the first nonzero number -Zeros between nonzero digits are counted as sig. Figures -Terminal zeros (zeros to the right of the right of a number) are always significant if the value contains a decimal point. Ex: 2. 3700 g: 5 significant figures 17. 50 mL: 4 significant figures Rule 1- In calculations involving measured values (with a certain # of sig. figs), the number of sig figs in the final answer depends on the operation performed. Rule 2- In multiplication and division of measured quantities, the final answer contains the same number of sig figs as are in the measurement with the least number of sig figs. Rule 3- In the final answer of a calculation involving exact numbers, unit conversion factors and constants, the number of significant figures is dictated by the measured quantity involved. Density = Mass/ Volume Matter: The term matter is used to describe things that occupy space and are perceivable by our senses. It can be classifies in terms of its physical state or chemical composition. Elements: composed of one type of atom. Classified as a metal, nonmetal or metalloid. Compound: a combination of elements in a definite proportion. Atoms of each individual elements are chemically combined to form the compound. A chemical change can break down a compound into its individual elements. Mixture: a non-pure substance made of 2 or more elements or compounds that can be separated by physical procedures. Protons have a positive charge, found in the nucleus. Neutrons have no charge, found in the nucleus. Electrons have a negative charge. The atomic number of an element is equal to the number of protons in the nucleus of its atoms. The mass number is equal to the number of protons and neutrons in the atom. To calculate the number of neutrons, subtract the atomic number from the mass number. Molecules are a combination of atoms in a definite proportion e. g. , molecule of water Ions are charged species formed by loss or gain of electron(s) from an atom. Loss of electron – cation (positively charged) Gain of electron – anion (negatively charged) Chemistry 208 All QUIZ. (2018, Oct 12).

Teaching High School Badminton - Essay Example The objective of the researcher is to create a curriculum design for teaching badminton to a diverse high school population. The curriculum must also address students who went through special education. It is a modified form of instruction that caters to students with singular needs or disabilities such as learning differences, mental health problems and other physical and developmental disabilities. Since the majority of the students with disabilities that have returned to general education consists of: 1.) students that have health impairments such as asthma and other chronic health conditions with proper medical clearance and, 2.) students with learning disabilities such as speech and language impairments1, the curriculum would deal with such students in order to narrow the broad scope of students taking special education. Learning disabilities are neural conditions which affect many areas of perception such as: 1.) visual or auditory discrimination, the perception of differences in either sights or sounds, 2.) visual or auditory closure, the completion of missing parts of sights or sounds, 3.) visual or auditory figure-ground discrimination, the ability of a person to focus on an object and disregard the background, 4.) both short term and long term visual or auditory memory w... right order, 6.) auditory association and comprehension which relates what is heard to the meanings of words and sentences, 7.) spatial perception which allows a person to perceive his laterality and his position in space, 8.) temporal perception, the processing of time intervals in the range of milliseconds and, 9.) non-verbal learning, the processing of nonverbal cues in social interactions.Because badminton is a racket sport that requires a great deal of hand-eye coordination and at a certain pace, may require its players to have aerobic stamina, strength and speed, drills and conditioning exercises that would augment the learning process of students with learning disabilities and physical constraints should be added in the curriculum.There are many specialized terms associated with curriculum design, these terms are not defined the same way by many professionals in this field. According to David Armstrong, these are the basic design concepts that must be considered when one is de signing a curriculum: 1.) scope, 2.) sequence, 3.) articulation, 4.) continuity, and 5.) balance.2 Scope "refers to the extent and depth of content coverage."3 This is very significant in curriculum development because of its dependence on instructional time. Since the time given for a certain subject is fixed, expanding the coverage in one area would lead to the reduction of the coverage of another area. The scope can be molded by these considerations: 1.) legal constraints, 2.) content significance, 3.) content authenticity, 4.) motivational appeal, 5.) content complexity, and 6.) the instructor's background and support-material availability.4Legal constraints refer to the decisions that cannot be changed by the curriculum developers. These are usually mandated by

Women Characters in Othello and The Rover Essay Example | Topics and Well Written Essays - 750 words

Women Characters in Othello and The Rover - Essay Example The plays â€Å"Othello† by William Shakespeare and â€Å"The Rover† by Aphra Behn bear the essence of their time and most importantly both these contemporary plays have emerged beyond their time, captivating some of the most recent post-modern interpretations and feministic bent of perception has been poignant in their purview. Role of Women in the Plays â€Å"Othello† and â€Å"The Rover† Against the Context of the Male Dominated Society In order to discuss the alternative role of women in the plays that has evolved from a male –dominated society, it is essential to judge the genre of both the works as the nature of the plays shall evidently determine the perspective from which the women and her empowerment as an alternative factor in a society dominated by masculine facades are presented. It is noteworthy that the play, â€Å"Othello† by William Shakespeare is out and out a tragedy, where Desdemona, the victim and the wife of Othello falls prey into the trap of misunderstanding and false infidelity from her husband’s end. On the other hand, â€Å"The Rover† by Aphra Behn is a very popular Restoration Comedy where there are multiple plots and intriguingly all of them contain women as a pivot to the plot development. In â€Å"Othello† Shakespeare has tried to portray a strong Venetian patriarchal society where the women are viewed as an object of possession, an entity of subjugation, a temptress and a whore but at the same platform they are also viewed as powerless creatures falling into the omnipotent and all-pervasive clutches of destiny designed by men themselves. The three women character Desdemona, Emilia and Bianca are seen at the outset of the play respecting men almost to the point of worshipping them. But Desdemona’s tragic trajectory definitely serves as a lesson to the other women and Desdemona as well. Emilia is seen evolving out as a power centre in the play after the tragic con sequence of Desdemona and by the climax of the play, women characters in the play are shown internalising society’s expectations about them. On the same platform they were shown to subjugate under and accept the male authority, behaving the way men want them to react and that seems ‘natural’ to them and to the readers. But in their private moments, they are seen evolving as an alternative power centre in the male dominated society, ‘Nay, we must think men are not gods’ (Shakespeare, 2008). The evolution or the transformation of women characters and the kind of language and actions of women characters incorporated in the plot of the play â€Å"Othello† by Shakespeare indicate that Shakespeare’s three women characters although seem subservient but the women characters in the play exhibit a role that indicates a step tentative of approach towards an egalitarian society. This is achieved by the female characters of the play by coming out of the conventional role allotted to the women by men folk of the society. The play â€Å"The Rover† is an excellent piece of restoration comedy which was written in two halves and the first part is divided into five plots. There is a definite and pertinent feministic bent within the plot of the play which is displayed through fragmented instances and incidents in the play pertaining to women, vulnerable to rape. Also the tragic consequence of Angellica after being jilted by Wilmore, it becomes quite obvious that Behn used the platform of comedy to launch a protest movement against the powerless status of women in her society. Every plot of the play has a women character subjugated to injustice and misery in the play. And all these women characters simultaneously try to break free the conventional role assigned to them by the society to evolve out as peer and sometimes superior to the men in the play. For
