Exam (Opportunity to Excel, of course!!)
Covers Units on the Solar SystemThis exam will be conducted on the Internet. You will be able to take it from anywhere you have access to the WWW, even the beach! Your instructor has already assigned your ID and password to you. Do not forget this or you will not be able to take the exam. The exam is stored at: http://eclipse.stkate.edu Do NOT try to start the exam without allotting enough time to take it completely. There are 50 questions. If you take one minute per question, it will take the better part of an hour to complete. Some people can complete it in less time. You cannot do part of it and come back later. The exam is closed book, closed notes, closed search engines, etc. You are on your honor to take this independently.
When you access blackboard.com you will find a "STUDENT" box located in the upper right hand quandrant of the page. From here you can "search" for our course. It is titled PHYS104. If you type this in, it will take you to a link to the course. You here indicate that you are a student enrolled in this course. (No other people may access our exams but our class.) You will be asked for your USER Name and Password.Once you are logged in it will lead you to a page with a lot of buttons on the left hand side. Select the one called "ASSIGNMENTS" When you do, a folder labeled "QUIZZES" will appear on the screen. When you click on the word QUIZZES the option of taking Astro Test 2 will appear. This is our second exam. Take the exam, selecting the Best answer. Some of the misleads may not be totally wrong, but may not be the BEST answer. You can go back and change your answers. When you are satisfied with your test, SUBMIT the exam. It will grade and give you immediate feedback. You will not be able to retake the exam. Plan enough time for the exam.
Lab#6 You will be assigned a specific laboratory activity that is consistent with the weather and where you are in the objectives. Check with your instructor before you forge ahead.Outside:

Physics Holiday! No Class! (Hah! Actually, It's SPRING BREAK) Are we having fun yet !!!![]()
Come on back, ready to study the nature of stars, their structure and evolution.
Tuesday, March 20th, 2007 at 7:08 PM (CDT)
http://www.equinox-and-solstice.com/html/vernal_equinox.html
Today we have the occurence of the Vernal Equinox. Far from being an arbitrary indicator of the changing seasons, March 20 (March 21 in some years) is significant for astronomical reasons. On March 20, 2006, at precisely 12:26 P.M. CST (18:26 Universal Time), the Sun will cross directly over the Earth's equator. This moment is known as the vernal equinox in the Northern Hemisphere. For the Southern Hemisphere, this is the moment of the autumnal equinox.The Sun is actually in Pisces (as seen from the Earth - remember, it is the Earth that is moving, not the Sun) as it moves to this point.The Astronomical Definition is well known. Have you ever heard of trying to stand an egg on end during the equinox? What a cool weekend activity. Naaah! The position of the equinox has changed over the millennia with respect to the fixed stars. The vernal equinox which is both a time and a direction in space is called the first point of Aries. Find out why it is in Pisces now and when last it was in Aries. Noruz is the oldest continuously celebrated human holiday. The Vernal equinox was in Taurus when this celebration began 5,000 years ago. Find out when we will really enter the age of Aquarius.
