Chemistry Syllabus Kristy Halteman kristy.halteman@carlisle.kyschools.us Room 114 About this class: We will be discussing topics concerning chemistry. The content of this class is determined by the content standards set by the Kentucky Department of Education. (See Attached) The Rules: Come prepared for class and follow proper classroom procedures. If you do these 2 things, everyone will stay happy! Throughout the course, we will be engaged in several laboratory activities. Students will not be allowed to participate in lab activities requiring Bunsen burners until they have read and signed the attached lab safety agreement, and a parent or guardian has done so as well. Students who have not turned in a signed syllabus or do not adhere to the rules will be removed from the lab and will be given an alternate assignment. By signing this syllabus you agree to adhere to the attached lab safety rules. The school policy for discipline will be strictly followed. The consequences for level 1 violations are outlined below. Consequences: First time- Warning Second time- Office Referral See your handbook for consequences of other level infractions. Academic Dishonesty: Plagiarism or copying will not be tolerated. The student will be given a zero on an assignment on the first incidence of academic dishonesty. No excuses! Remember that it is academically dishonest to let someone copy your work OR to copy the work of someone else. See the student handbook on procedures concerning academic dishonesty.

Your final exam will be comprehensive and will make up the other 20%. To calculate semester grades use the following equation: 1st 9 weeks average x .20 2nd 9 weeks average x .20 3rd 9 weeks average x .20 4th 9 weeks average x .20 + semester exam x .20 Grade for the course = Laboratory Safety Agreement I,_________________________________, have read and understand the following safety agreement. I agree to comply with all of the safety rules and guidelines stated below. Furthermore, I agree to follow any additional printed or verbal instructions given by my teacher or supervising adult during the school year. 1. Be prepared to work in the laboratory. Read the experiment and complete the prelaboratory assignment. 2. Perform the experiments as directed. Do not do anything that is not part of an approved experimental procedure. 3. Never work without adult supervision. 4. Dress appropriately for lab. a. Clothes should not be loose or floppy, especially in the sleeves. b. Dangling necklaces or bracelets should be removed for lab. c. Tie back long hair to keep it away from flames and chemicals. d. Wear shoes that cover the entire foot. e. Avoid wearing contact lenses. 5. Wear appropriate protective equipment. Safety goggles and a lab apron or coat must be worn at all times. Gloves may be needed to protect your hands. 6. Learn the location and operation of emergency equipment. This includes eye washes, safety showers, fire extinguishers, fire blankets, sinks, and first aid supplies. Know what to do in case of an emergency. 7. Act in a responsible manner at all times. No horseplay or fooling around in the lab is allowed at anytime. 8. Do not eat or drink in the laboratory. 9. Never taste a chemical. Check odors only if instructed to do so, by gently wafting some of the vapor toward your nose with your hand. Be sure your work area is well ventilated for your experiment. 10. Turn off your Bunsen burner or other heat source whenever you are not using it. Never leave it unattended. 11. Keep all combustible material away from open flames. 12. Read chemical labels very carefully. Read them when you pick the bottle up, just before you use the chemical, and after you are finished measuring the chemical. 13. Report all accidents, injuries, and close calls to your teacher immediately. 14. Dispose of chemicals properly. No solid material goes down the drain. This includes burned matches. When solutions are disposed of down the drain, use plenty of water dilute the chemicals. 15. Never return used reagents to reagent bottles. Be careful to take just the amount you need. Do not contaminate the reagents. 16. Clean up the spills immediately. This includes water! Wash off chemicals splashed or spilled on your skin immediately and notify your teacher. 17. Treat all chemicals with respect. Know the hazards before you handle any chemical. 18. Clean up your work area. Put away all equipment and reagents and wash your hands thoroughly before leaving the laboratory. 19. List your allergies at the bottom of this Safety Agreement. If the experiment you are doing involves a substance you are allergic to, consult your teacher immediately. Chemistry Core Content Structure of Atoms SC-H-1.1.1 Matter is made of minute particles called atoms, and atoms are composed of even smaller components. The components of an atom have measurable properties such as mass and electrical charge. Each atom has a positively charged nucleus surrounded by negatively charged electrons. The electric force between the nucleus and the electrons holds the atom together. SC-H-1.1.2 The atom’s nucleus is composed of protons and neutrons that are much more massive than electrons. When an element has atoms that differ in the number of neutrons, these atoms are called different isotopes of the element. SC-H-1.1.3 The forces that hold the nucleus together, at nuclear distances, are usually stronger than the forces that would make it fly apart. Nuclear reactions convert a fraction of the mass of interacting particles into energy, and they can release much greater amounts of energy than atomic interactions. Fission is the splitting of a large nucleus into smaller pieces. Fusion is the joining of two nuclei at extremely high temperature and pressure. Fusion is the process responsible for the energy of the Sun and other stars. Structure and Properties of Matter SC-H-1.2.1 Atoms interact with each other by transferring or sharing outermost electrons. These outer electrons govern the chemical properties of the element. SC-H-1.2.2 An element is composed of a single type of atom. When elements are listed according to the number of protons, repeating patterns of physical and chemical properties identify families of elements with similar properties. The periodic table is a consequence of the repeating pattern of outermost electrons. SC-H-1.2.3 Bonds between atoms are created when outer electrons are paired by being transferred or shared. A compound is formed when two or more kinds of atoms bind together chemically. SC-H-1.2.4 The physical properties of compounds reflect the nature of the interactions among molecules. These interactions are determined by the structure of the molecule including the constituent atoms. SC-H-1.2.5 Solids, liquids, and gases differ in the distances between molecules or atoms and therefore the energy that binds them together. In solids, the structure is nearly rigid; in liquids, molecules or atoms move around each other but do not move apart; and in gases, molecules or atoms move almost independently of each other and are relatively far apart. SC-H-1.2.6 In conducting materials, electrons flow easily; whereas, in insulating materials, they can hardly flow at all. Semiconducting materials have intermediate behavior. At low temperatures, some materials become superconductors and offer no resistance to the flow of electrons. SC-H-1.5.3 Heat is the manifestation of the random motion and vibrations of atoms, molecules, and ions. The greater the atomic or molecular motion, the higher the temperature. Chemical Reactions SC-H-1.2.1 Atoms interact with each other by transferring or sharing outermost electrons. These outer electrons govern the chemical properties of the element. SC-H-1.2.3 Bonds between atoms are created when outer electrons are paired by being transferred or shared. A compound is formed when two or more kinds of atoms bind together chemically. SC-H-1.3.1 Chemical reactions occur all around us and in every cell in our bodies. These reactions may release or consume energy.
