General Chemistry II with Lab – Summer 2015 (session II) Instructor: Harrison Neal, nealh@evergreen.edu Program Website: https://canvas.evergreen.edu/courses/578 Program Locations: Lectures in SEM2 C-3105, Lab in LAB2 1241 Course Description GENERAL CHEMISTRY II (8 credits possible, reference number 40054) is the second of two courses in the general chemistry sequence for students over the summer quarter. Students must have taken the previous iteration of this course (General Chemistry I) or the first half of the year-long college level general chemistry course or equivalent. The topics to be presented will include thermochemistry, properties and physical changes of matter, solution chemistry, kinetics, thermodynamics, chemical equilibrium, acid-base chemistry, and aqueous equilibria. We will also be exploring relevant and current research topics throughout the class. Additional topics in electrochemistry, nuclear chemistry and coordination chemistry may be presented if time permits. Student Learning Outcomes At the end of this course, you will be able to analyze data (experimental and theoretical) and determine the specifics of the different states of matter and their properties, reaction kinetics, energy transfer, reaction direction and equilibrium. You will also have a working knowledge of aqueous acid/base chemistries. You should be able to relate all of these topics to real everyday life experiences but understand the topics from a pure scientific standpoint as well. Expected improvement of: 1. Asking and answering questions in an objective and scientific manner using hypothesis, experimentation and discussion. 2. Solve problems from both a conceptual and numeric pathway. This includes conceptual understanding of equations and what the relations of variables mean. 3. Communication of scientific ideas and topics in group discussion, written and presentation style settings. 4. Connect chemical knowledge and topic understanding to the world around you and understanding the state-of-the-art research that is being done today of some of the topics discussed. Achieving success in General Chemistry II Your success in GENERAL CHEMISTRY II will depend on your devotion to the mastery of the materials we discuss during the term. The class consists of meetings July 27th through August 28th, Monday-Friday from 9am – 2pm with evaluation week (conferences optional) on August 31st to September 4th. This includes lectures, small-group problem-solving workshops and laboratories. Experience shows that math competency is often a deciding factor in achieving success in this class. You should be at proficient math skill in and including concepts in college level algebra. As this is not a required prerequisite, students that have difficulty with math can decide to seek help at the QuaSR in LIB 2304 to improve math skills for greater success in this course. Description of Assignments Homework There will be practice homework assignments from each section of the book assigned on the handout attached to this syllabus. All students are responsible for the materials in the problem set provided as they will appear on quizzes and exams and may be considered in the final evaluation. Quizzes and Exams There will be one quiz for each topic discussed making for 8 total quizzes over the course. There will be one midterm exam (tentative date August 14th) and a final exam before evaluations. Students should provide a writing utensil, and calculator or communicate with me ahead of time. All other necessary materials will be provided including an equation sheet and periodic table. Laboratory experiments Lab safety – All students that participate in lab must be dressed appropriately with no exposed skin below the waste (including long pants of a thick material, jeans preferred and closed toed shoes that cover the top of the foot) and you must also wear a shirt that covers your shoulders (no tank tops or spaghetti straps). You are required to have your goggles on at all times that there are chemicals out and/or being used in the lab THERE ARE NO EXCEPTIONS. You are always welcome to step outside of the lab, remove your goggles and take a break whenever needed, no need to ask for permission as long as this is not abused. If you do not come prepared you will either be asked to make adjustments to your attire or be asked to leave without credit for that day’s lab activity. You have already been shown proper lab etiquette and safety in General Chemistry 1 and these rules still apply. If for any reason I feel that there is/are student(s) performing unsafe practice of any kind in the lab, the student(s) involved will be asked to leave and receive no credit for the lab for that day. Under extenuating circumstances such as power outage, student injury, fire, etc. I reserve the right to cancel all lab proceedings with no penalty to students’ final evaluations. As a significant portion of chemistry and chemical understanding is facilitated in a laboratory setting, this part of the course is essential for learning for chemistry and all other aspects of science. Each of the lab experiments will be posted prior to the lab time and an email remainder will go out to the class once they are visible on Canvas. As lab time is precious, I am going to strongly emphasis a safe and efficient work ethic in lab, because of this each student will be required to print out, read and answer the short pre-lab before the scheduled lab time. All pre-lab assignments will be used in your final evaluation. On the first day of lab I will give you specific safety instructions to use throughout the course. Any persons showing continued or purposeful violation of these safety rules will be dismissed from the lab and met with individually. The design of the lab is to have you use the information provided in the lecture/workshop instruction in a real, hands on experiment. The first lab is designed to allow you to create the experiment yourself and to initiate scientific thinking and experimental planning to solve a specific problem. The labs that follow are more in-depth lab practice and instrumentation so the experimental methods are laid out in advance. These labs are still designed to have you thinking critically about what you are being asked to do, why, and what the results of the experiments mean. Any new instrumentation will be demonstrated by myself so that students understand correct instrument operation techniques. Lab reports are essential for scientists to convey what they have done and to help others to understand the thought process and findings of an experiment. These reports are introduced in this class as lab-sheets with guided questions. These lab-sheets should be written so that your peers would be able to recreate your experiments, reproduce your results and understand your thought process. Just because an experiment doesn’t give the desired result does not mean it is a failure, all of the work done in research in the real world is off of trial and error so think about your results thoroughly and if they do not make sense you should be able to identify and express that in the lab-sheet. These lab-sheets will be considered for your final evaluation. Seminar discussions Reading and understanding scientific literature is a very important skill for all scientists to gain and building on these skills as early as general chemistry is an important focus for this class. You will be provided with articles from chemical literature sites as well as chemistry news articles. You will need to read these articles and produce answers to questions posed such as: 1. Identify the objective the author is trying to portray or experiment. What are the author’s findings? 2. Write down clarification questions or concerns related to the articles. What a specific compound or term may mean to help your understanding. 3. What relevance can you find that relates this article to our class topics and how has it used the themes of general chemistry to frame the work? 4. Spend about five minutes writing about a broad question related to the reading. This should be related to the topic, but shouldn’t simply repeat what the author said. What did this reading get you thinking about? What did you think about the argument presented? Do you see connections to other topics we’ve covered in this program, or in other programs? 5. Come up with another experiment you would do to further the research and to answer some lingering questions you have from #4. Be creative with this but stay grounded in reality. These written responses to the article will be collected. During the designated group workshop times we will be discussing each of the research articles and how it relates to the topics we have discussed in class. We will be using the above questions each student has prepared to facilitate discussion. All of these discussion sections and written responses will be used in your final evaluation. Many of these articles can be difficult to grasp and hard to understand at a general chemistry level, I will be making the questions very guided where required and only key aspects relevant to this course will be discussed at length. Final report and presentation For your final assignment in this course, you will explore a topic of your interest in chemistry that relates to the content of this class. You will find an article discussing this topic and write a research paper with the below requirements. 1 page (no longer) research paper expressing the article and topics completely. A brief summary of the article including major ideas and findings (do not plagiarize, write this in your own words using scientific terms when relevant). Discuss a piece of chemistry-related information in the article and explain how it is connected to a topic you have learned in this course. Identify another piece of chemistry-related information from the article that you would like to learn more about. Explain why you are interested and investigate this topic, describing your findings. You should include references to the paper and at least 2 other sources as foot notes. Following this research paper you will prepare a one slide presentation, summarizing the article, expressing your interest in the work and one of the two pieces of chemistry-related information you discussed in your paper (either how it relates to the class or a topic you researched more about). These presentations will occur on the last 1-2 days of class. Each presentation will be 5 minutes long with open class questions. You should ask questions of your peers during their presentations, I will be keeping track for your final evaluation. All of these materials: research paper, presentation and relevant questions will be used towards your final evaluation. Evaluations You must write an evaluation of the faculty member and a self-evaluation at the end of the quarter. It is optional for you to submit your self-evaluation to the Registrar for your transcript. Student expectations: 1. If you must miss class (for reasons such as illness or a family emergency), you must let me know in advance. 2. Due to the fast pace of this program, I will not accept late work. If you believe you have extenuating circumstances that require extra time, you must let me know in advance. 3. Be on-time. 4. Do not engage in distracting behavior. We are all adults and we are use cell phones for everyday life. I’m not your parent, if your laptop your phone becomes a distraction I ask you to correct yourself or leave. Please keep your cell phone off or on vibrate during class. If you must take a call I understand but please excuse yourself and leave the room. 5. Be engaged and participate during class. 6. Don’t cheat or plagiarize any material. I have ZERO tolerance for cheating. 7. Maintain a safe, respectful, and collaborative environment at all times. Disabilities: If you have a disability that will affect your learning, or if you need assistance in any way, please let me know. Also, be sure to contact Access Services (Library 2153), which provides a variety of different types of support for students with disabilities, including testing accommodations. Tutors: The Quantitative and Symbolic Reasoning Center (QuaSR) has a part-time tutor available specifically for General Chemistry II, as well as a full-time chemistry tutor. The QuaSR center is located in the library, room 2304 (www.evergreen.edu/mathcenter). Also, The Writing Center (www.evergreen.edu/writingcenter) is a great resource for students needing help with writing skills, and the center offers one-on-one tutoring.
