INTRODUCTION

PHY250 is a single term introductory course in astronomy.

Many of the students enrolled in PHY250 are education majors.  The State of Ohio defines Academic Content Standards for "Earth and Space Sciences" which serve as benchmarks for K-12 instruction.  Detailed information regarding the State of Ohio standards for teaching can be found in the "Standards and Instruction" link at the Ohio Department of Education website.  If you prefer, you can go directly to the Academic Content Standards where you can review content standards for science and mathematics, as well as all other content areas, or you can go directly to the Science Academic Content Standards.

Syllabus for PHY250

ALL EXAMS ARE CLOSED BOOK, WITH NO FORMULA SHEETS OR CALCULATORS

All test must be taken at the assigned time. A makeup exam is scheduled for those with a LEGITIMATE WRITTEN MEDICAL EXCUSE. Missed test without such an excuse will be assigned a zero. Makeups are not given to replace a low score on one of the four tests.

MAKEUPS: The makeup exam day is listed on the calendar. All makeups will be given at this time. Those with a valid excuse must obtain a REQUEST FOR MAKEUP EXAM form from the instructor of the course. The form must be filled out and signed by the instructor. Students who have not filled out a request form will not be allowed to take a makeup exam.

Basic Skills Quizzes

The area of Astronomy relies upon an understanding of many areas of physics and mathematics.  In order to demonstrate (or build) skills that will be relied upon during the course, each student enrolled in PHY250 must complete a series of electronic Basic Skills Quizzes.  These quizzes demonstrate knowledge in these basic areas and will be used as a stepping stone to techniques that will be utilized during the course.

Lecture Materials

The first link will take you to lecture material presented in a Powerpoint presentation format.  The second link contains other lecture materials not in a powerpoint format.

Some Resource Sites

Note:  There has been some problems with the first Messier site, so I have listed three different sites.  The first Messier catalog is, in my opinion, the best, but the others have the information you need as well, but no photos.  The fourth site contains photos but no data.

Note:  Angular diameters in these catalogs are given in minutes (symbolized with a ').  A minute is defined so that there are 60 minutes in one degree.  Therefore, for example, an angular diameter of 30' corresponds to an angular diameter of one half degree.
