I have decided to keep this CO information at the top of this webpage because it illustrates
how dangerous CO really is.
More CO News (Below list will be updated all Spring semester)
Carbon Monoxide Victims of 2024--------Deaths and Non-Lethal Exposures
All semester I intend to add links that lead to CO deaths/accidents that occurred during this semester.
I want to show how many cases there are and how needless (and preventable) the losses are.
Be aware that links to newspapers (and the like) often go dead after some time due to their management of web content.
I will not be able to post all CO cases, but the ones I do post will for sure give you an idea how these poisonings happen.
Total deaths since the semester started on January 8th = 31 people
February 24, 2024---Man dead, woman in critical condition from CO in Baltimore

Replaces class today-A video
For A9, the Q that starts with "On various farmes, incandescent........."
Was not graded, everyone earned 5 pts. from that Q.

A comment on the grading of A7. The Q that referred to "This scientific technique involves
the automatic recording........" was not graded. Everyone received the full 5 points for that Q.
And remember that 5 points are added to everyone's score because most assessments have 75 points
possible, but the syllabus states 80 points. This has been stated in class several times. Finally, A7 was
worth 90 points possible because of the way the Five Freedoms question took up 20 points.
So that means A7 had 10 bonus points possible. 18 students scored 90% and above on A7.
And of those students, 6 scored 100% or above.

****************************************************************************
How all assessments will be graded (80 pts)
1) All assessments will have 15 questions.
2) All Qs will be worth up to 5 pts (with partial credit awarded when possible)
3) After calculating points earned, an additional 5 pts will be added to the final tally.
4) A check mark in the left margin by the question indicates the Q earned
the full 5 points possible.
5) A "X" mark near the end of the Q on the right side means zero pts awarded.
6) A number near the end of the Q on the right side indicates partial credit awarded.
7) Rod will make copies of all assessments before returning to students. So if you lose an
assessment, Rod can give you a copy of your orginal assessment.

After class on this past Monday (1/22), a current student in our course came up to me after class
and said they had been best friends with the young man (Colton Howard) who died in the
grain bin accident I discussed that day. I heard more about the events on that fateful day
and the story made me very sad.
