1) Students will complete a 4th quarter research project involving writing a paper and giving a presentation on a topic of their choice that has a connection to chemistry.
2) They must get their topic approved by March 27th then research it, writing a 3-5 page paper with at least 4 references from different sources including a journal or book.
3) The paper should have an introduction, body, and conclusion section and be properly cited and referenced according to MLA format. The final paper and presentation will be graded.
The document provides grading criteria for a student paper assignment. It lists the following requirements for the paper: a title page with student name, period, and date; 3-5 double-spaced pages in 12pt Times New Roman font with 1 inch margins and page numbers. The paper must also include a works cited page with proper citations using Noodletools. The grading criteria cover purpose, content, organization, tone, sentence structure, length, quality of sources, and proper use of MLA format.
This document compares the key differences between ideal gases and real gases. Ideal gases are made of small particles with mass that have no volume and undergo perfectly elastic collisions with no attractive or repulsive forces. In contrast, real gases have small attractive and repulsive forces between particles, the particles have a small volume, and collisions result in a loss of kinetic energy rather than being perfectly elastic.
The document discusses the concept of a mole in chemistry. It defines a mole as the amount of substance that contains as many elementary entities (atoms, molecules, ions) as there are atoms in exactly 12 grams of carbon-12. This number is known as Avogadro's number and is equal to approximately 6.022x10^23. It provides examples of how to use moles to convert between the number of entities and mass or vice versa. It emphasizes setting up mole calculations step-by-step rather than randomly using a calculator.
This document provides instructions for a chemistry webquest on chemical reactions. Students are asked to identify and predict types of chemical reactions, such as single displacement reactions and double displacement reactions. They also practice using solubility tables to determine if combinations of compounds will precipitate out of solution or not. The webquest includes links to online activities and videos to help explain these concepts.
The document discusses valence shell electron pair repulsion (VSEPR) theory for determining molecular shapes. It explains that electron pairs orient themselves as far apart as possible to minimize repulsion. Lone pairs repel more strongly than bonding pairs. To determine shape, one draws a Lewis diagram, counts electron pairs around the central atom, and considers the five most common shapes based on bond angles.
The document is a lab activity on molecular polarity using a PhET simulation. Students investigate how electronegativity affects bond polarity and molecular polarity when atoms bond. They describe different bond types such as nonpolar covalent, polar covalent, and ionic based on the electronegativity values of the atoms. Students also explore how molecular polarity arises from bond dipoles combining through vector addition and how molecular polarity determines if molecules will dissolve in polar solvents like water.
The document discusses ionic and metallic bonding. Ions are formed when atoms gain or lose electrons to achieve a noble gas configuration. Ionic bonds form when cations (positively charged ions) and anions (negatively charged ions) are attracted via electrostatic forces. Metallic bonds occur in metals and involve delocalized electrons that provide conductivity and allow metals to be malleable. Ionic compounds are named by writing the cation name followed by the anion name.
This document outlines 7 extra credit opportunities for a chemistry class worth 3 points each, up to a maximum of 5 points added to a previous test grade. The opportunities include making an element card about a synthetic element, completing online activities about naming ionic compounds, and creating posters or flashcards about topics like naming ionic compounds, their properties, and identifying ionic compounds in common products. Students must complete the assignments at an excellent level by the due date to receive full extra credit points.
