Learning Goals, Course Objectives

Chemistry 362 is designed to advance students toward the WSU Learning Goals, especially Scientific Literacy, Critical and Creative Thinking, Quantitative Reasoning, Communication, and Information Literacy. The goals of Chem 362 are to provide students with laboratory instruction in radiation safety, measuring radioactive materials, interpreting the data collected from the analysis of radioactive materials, assessing radiological hazards, providing radiological safety recommendations, and addressing health physics scenarios as well as writing formal laboratory reports. Chem 362 focuses on the use of modern spectroscopic techniques for the analysis of radioactive materials to assess radiological hazards and provide radiation safety recommendations. The laboratory work is complemented with lectures highlighting pertinent radiation detection methods, radiological hazards, and radiation safety. This course will reinforce the techniques and skills that radiation workers employ in their work, and students will be encouraged to develop their lab skills in an independent manner.

Expectations for Student Effort

For each hour of lecture equivalent, students should expect to have a minimum of one hour of work outside class. For each three hour of laboratory equivalent, students should expect to have a minimum of two hours of work outside class.

Grading [add more lines if necessary]

The grading scale will be administered in accordance to the policies of the WSU university registrar. There will be no exams given in this course. The student's final grade will be based on safe lab performance: experimental write-ups, a safety quiz, a safety poster, experimental accuracy, and laboratory technique. Note your class participation grade will be affected negatively by the lack of preparedness for labs and the lack of attendance.

Assignment Breakdown
Type of Assignment (tests, papers, etc)	Points	Percent of Overall Grade
Formal Lab Reports	650	65
Health Physics Scenarios Lab Reports	200	20
Safety Quiz	100	10

SAFETY QUIZ: There will be a safety quiz due at the beginning of the lab period on August 26^th, 2027. The quiz will focus on the material discussed on the first day of class and will be available on Canvas. There will be no makeups and it must be completed before you can start your first experiment.

SAFETY IN LABORATORY: You will not be permitted to begin an experiment without having read the safety instructions completely. Students will be actively preparing and handling radioactive materials.

Safety Goggles are required at all times. A pair of rubber latex gloves is strongly recommended. Report any spills at once.

No one is allowed to work alone in an unsupervised laboratory. Some experiments in this course are dangerous if not carried out properly. If you need extra time to complete an experiment, there is ample time supplied in the course schedule that it can be completed prior to the laboratory report due date. Experiments have been selected and designed to utilize all the safety precautions and equipment available to limit chemical and radiological material exposure.

LAB REPORTS: Each student is required to use a lab notebook with numbered duplicate pages. In this notebook, each student will keep a record of collected data and experimental observation. You are not permitted to use the same notebook or replicate lab reports. A template for the lab report can be found on Canvas. The reports must be written in a word processor and submitted via Canvas as a single pdf. Lab reports received via email will not be accepted. The lab report is due for each completed experiment no later than two Wednesdays after the scheduled experiment ends by 11:59 pm. Late lab reports will be penalized 25% per calendar day. Questions regarding a lab report or a completed experiment are welcomed and encouraged, but not the last day they are due.

LAB DATA: Students are responsible for collecting their own characterization/spectral/lab data.

LECTURES: Lectures will be presented in person at the scheduled class time in Dodgen 150.

ONLINE CONTENT: Information of the current and upcoming experiments, course lectures, announcements, and literature will be available on the Canvas course page (http://canvas.wsu.edu) for CHEM 362.

Attendance and Make-Up Policy

Attendance is mandatory in this course. Unexcused absences will not be allowed to be made up. If you plan to be absent from the laboratory because of unforeseen or foreseen circumstances you must notify the instructors in writing explaining your situation, prior to the event. You must also give a copy of the letter to the TA. In addition, you need to arrange to make up the missed laboratory.
