This satisfies UCF general chemistry degree requirement, with an emphasis on materials and their application to engineering systems. You'll begin with an exploration of the fundamental relationship between electronic structure, chemical bonding, and atomic order, then proceed to the chemical properties of "aggregates of molecules," including crystals, metals, semiconductors, solutions and acid-base equilibria, polymers, and biomaterials. Real-world examples are drawn from industrial practice (e.g. semiconductor manufacturing), energy generation and storage (e.g. automobile engines, lithium batteries), emerging technologies (e.g. photonic and biomedical devices), and the environmental impact of chemical processing (e.g. recycling glass, metal, and plastic). Is This Course for Me? This is not "just a chemistry class" - it's a chemistry-centered class that integrates examples from the world around us, in the arts and humanities, the human stories behind the science, and applications to engineering and emerging technologies. Learning Objectives Upon successful completion of CHS 1440, students will have accomplished the following general learning objectives. General Predict the properties and interactions of chemical substances by understanding their composition at the atomic level, making connections to structure, bonding, and thermodynamics as necessary. Determine and apply principles of materials science (specifically microstructure design and selection) to the selection of materials for specific engineering applications. Expectations How much time will this class take? At UCF, this class meets 3 times per week, with three one-hour lectures by Mr. Roberts, and onehour recitation sessions divided into several sections. Can I work with others? Homework: At UCF, homework for this course is not graded. You should consider working assigned owl problems to be an essential part of developing your knowledge. At UCF, working together in

2 groups on is common and even encouraged. If you'd like to connect with others working on this course. Self-Assessment: The self-assessment and exam portions you should work on your own.. They are intended for you to demonstrate your mastery of the material. You should work these problems on your own, closed-book, using only a calculator, a periodic table and list of fundamental constants. Required Textbook and Supplies Chemistry for Engineering Students, 3rd edition, Lawrence Brown and Thomas Holme (Brooks/Cole-Cengage Learning) The book is available in a number of formats: Traditional hardcover textbook, Loose leaf textbook including e-book access and OWL access code You should choose whichever format you believe will work best for you. You will have an option of using OWL to do additional practice problems, but those will not count for course credit. Class Information and Announcements Announcements regarding schedule changes or other developments will be made in class at the earliest possible time. Information will also be available electronically via and the web. The class website can be found at UCF online on Canvas. This site offers a broad array of class information, including copies of the slide files used in class, old exams, and announcements. Course-related I will often distribute class announcements by . The only simple way to do this is through the Canvas system, which lets me send mail to the entire class roster. So any message I send out concerning class announcements will always go to your Canvas address. Please be sure to check that account regularly, or to set up a forwarding instruction if you prefer. Course Evaluation: Weekly Quizzes: These short quizzes are representative of the homework in classes, and an indication of the knowledge you should have in preparing for the exam and will be given in recitation. 3 Exams and Exam Problems: Exam will take place at logical breaks in the course( See Schedule).These problems based on homework and quizzes verify that you've developed the appropriate depth of understanding and application. Missed Exams There will be no regularly scheduled make-up exams. In the event that you miss an exam due to a university-approved absence, you should consult with me as soon as possible to discuss your situation. If possible, you should discuss your absence with me before the exam is given. Final Exam The Final Exam will be a two-hour and 50 minutes, 150-point test covering all material taught during the Semester according to the university s final exam schedule.
