For lecture class students, all activities are due in class and on paper, on the Wednesady scheduled. For online students, all activities are due, via the online submission form, no later than 10 p.m. on the date indicated. The deadlines are absolute. Let me repeat myself: Lecture class students MUST submit the activity during the Wednesday class period in which the activty is due. Online students MUST submit their activity write-ups by 10 p.m. on the Wednesday scheduled, through the online submission form only. Nothing will be accepted after these deadlines. There are NO exceptions except for "extenuating circumstances" as defined in the syllabus. The deadline is absolute -- for lecture students that is 10:50 a.m. on the scheduled Wendesday and exactly 10 p.m. for online class students. (At 10 p.m. the form closes and you will not be able to submit after that, not even if you are only one second late).  No late activities, no emailed activities, and no handwritten activities will be accepted. There are no exceptions, no extensions, no excuses.

SPECIAL OPTIONAL OPPORTUNITY: I am giving "
Colorado Skies" in Gates Planetarium on September 10. There is an admission fee and if you wish to go, you must make a reservation (303-322-7009). Here's the deal: you can attend this program, sign my attendance sheet after the program, and then submit a short descriptive write up afterwards in place of any activity. It must be submitted on the same schedule and in the same manner as whatever activity it is being substituted for. As long as you attend, sign the attendance sheet and submit a reasonable summary report, you will get full credit in place of one of those activities. This is not extra credit and cannot be used for extra credit, but it certainly can be considered easier than the original activity. For more information on the program, see this web page: Colorado Skies. This is a one-time offer.

PLEASE READ ALL 11 NOTES FOLLOWING:

NOTE #1: You must have your User ID and Password before you can submit activities online. Do not email activities. Do not attempt to access the Submit form for your activity submission until you are actually ready to submit. It is programmed to allow only one submission, so be sure you are finished with it before you submit. If you submit it and then find a major error or omission, you cannot go back and change it. If that happens and you discover it before the 10 p.m. due date deadline, you must email me the corrections before the deadline. However, as per the instructions in the "How to Submit" file, do NOT send any attached files without prior permission.

NOTE #2:For on campus students, activities are always due in class at the end of class period on the Wednesday of the week the activity is scheduled. I may also accept them via the online submission form, but no later than 10 p.m.on the Wednesday they are due. Activities from online students are due using the online form provided no later than 10 p.m. on the due date. Do not email your activity, and especially do not send attached files without prior permission. No activities (including alternates) will be accepted after the deadlines. No exceptions, no extensions, no excuses. Deadlines will be observed. If you are submitting online, be aware that they software is  unforgiving.If you exceed the deadline by even one second, your submission will be refused and you will get a zero. Period. 

When you have obtained your result and before you do your write up, make an effort to determine if your result is reasonable. If you are confused with the instructions or do not know how to check your answer, Ask before you submit your activity. Once you submit it, I will grade it as is.

NOTE #3: Some activities require outdoor observations. They do not require "perfect" observing conditions and should be able to be performed even from locations in town. It is expected that you will perform these observations from the safety of your own home or on campus. Under no circumstances are you authorized to perform these observations  from any location other than the campus or your own home. If you choose to make such observations from any other location, please understand that your safety is your own responsibility. If you feel that you cannot safety perform any observation for whatever reason, or if you cannot complete any activity due to a ADA defined disability, please contact your instructor for an alternate. 

NOTE #4: Some activities may require a bit of planning and should be started early. Some activities may require several observations over a period of weeks. Don't get caught too late to do these. Late activities, including alternates, are not accepted.

NOTE #5: Activities use the same submission software as the tests, but the reporting is a bit different. As soon as you submit an activity, you should receive a confirmation. Because the activities are basically "essays" and cannot be graded automatically, the computer will tell you that you got "0/10" or something like that. Don't panic! That just signifies that it has not been graded yet, but it confirms that you submitted it. You will be able to check it only when I have had the chance to grade it. After I have notified you that your activity has been graded, you may sign back on to the activity submit form to check your grade and my comments. Just click on "Key" instead of "Begin."

NOTE #6: When you check your results after I grade it, the initial grade may say something like 10/11 points, 90.1 percent, even though you actually got a full 10/10 points or 100 percent. This is a quirk in the software that I cannot fix. The important thing for you to know is that the only grade that counts is the the one reported near the bottom of the graded copy, just above my comments where it says something like SCORE: 10/10 . It also will be correctly reported in the gradebook, which you should check every time I tell you it has been updated.

NOTE #7: Your computer or Internet problems are not an acceptable excuse for missing an assignment deadline. You need to understand how your computer, browser and Internet connection work. Please plan ahead so that if you do have computer problems of any kind you will have time to find a substitute computer or another way of accessing the Internet to complete your assignment on time. However, if the problem is due to my error or a verifiable problem with the computer server that holds the required class material then I will consider an adjustment. (Other excuses not accepted include your  job or personal  schedule, your legal problems, your location, travel plans or the weather.)

NOTE #8: It is your responsibility to take all reasonable safety precautions and to complete the required activities either from the security of your own home or from the campus. No assigned activities require you to complete them from any location other than your home or the campus. If you choose to do so, you assume full responsibility for your own security. The optional or alternate activities may call for locations other than the campus. These activities are not required, however, and if you choose to do them, you assume responsibility for your own security. These provisions were not prompted by any adverse incident, but rather due to increased concerns over liability and insurance costs.

NOTE #9: I should not have to state this, but I will. Don't handwrite it, don't email it, and don't fax it. Online students must submit through the form provided. No other form of submission is acceptable, and no late submissions will be accepted.

NOTE #10: Students are welcomed, even encouraged to work with a partner or even a small group of other students. In that case, the data will be the same. However, each individual student must write up his or her own submission, including all 5 points of the format, as an individual work. I do not accept group submission, and I do not accept one student just copying over something that another student in the group has written. Furthermore, each paper from a student in a group must include the names of the other students in the group in the header.

NOTE #11: This also should really go without saying, but it is a problem often enough that I feel it is necessary to make it very clear: You are to do your own work. I encourage you to work with others, but you must write up the activity on your own. The use of other's students materials, or any hint of plagiarism or other forms of academic dishonesty, will earn a zero for the assignment, possible expulsion from the class, and notice to the dean. Don't cheat. It isn't worth it.
