Chemistry 221 Grades

We will cover 28 chapters from Caveman Chemistry and 4 from Principles of Modern Chemistry. All work for the course must be kept in a bound notebook, one whose pages cannot be removed. Such notebooks are commonly called “composition books” and may be purchased at the Hampden-Sydney bookstore, Walmart, or Roses. Any material which does not appear in the notebook does not count towards your grade. Your grade for the course is determined by the number of points you earn from the following sources:

  • Mercury: For each of the 28 Caveman Chemistry chapters there is a pass/fail reading quiz worth 1 point each.

  • Sulfur: For each of the 28 Caveman Chemistry chapters there is a pass/fail test worth 1 point each. You may re-take each test until you pass it, but I will grade no more than three tests per person per day.

  • Salt: For each of the 28 Caveman Chemistry chapters there is a project worth 1 point each. Project results must be documented in the course notebook, as described in Appendix B of Caveman Chemistry. I will grade no more than one project per person per day.

  • Each time you complete Mercury, Sulfur, and Salt for a chapter of Caveman Chemistry you will be awarded an extra point. This policy encourages you to balance book-learning and real-world experience.

  • You may receive a maximum of 50 points for Mercury, Sulfur, and Salt (i.e. the material covered in Caveman Chemistry.)

  • Copper: For every homework problem set you work you will be awarded 1 point, up to a maximum of 10 points. Homework sets consist of self-graded problems from Principles of Modern Chemistry, for which the answers are in the back of the book. In addition, there are four graded homework sets from Chapters 12, 13, 15, and 19. I will record no more than one problem set per person per day.

  • Silver: For each reading assignment from Principles of Modern Chemistry there is a quiz worth 1 points each. You may take a quiz early, but you cannot make it up after the date of the reading assignment.

  • Gold: During the first week of class, you must take the Chemical Concepts Inventory, worth 4 points. You may retake the Inventory as many times as you wish until you are satisfied with your grade. After each taking, you will be informed only of the number of questions answered correctly. I will grade no more than one Inventory per person per day.

    At any time during the semester, you may take a practice ACS standardized exam in General Chemistry, worth 5 points. You may retake the practice exam as many times as you wish until you are satisfied with your grade. After each taking, you will be informed only of the number of questions answered correctly. I will grade no more than one practice exam per person per day.

    At the end of the semester, you must take the ACS standardized test in General Chemistry, worth 10 points. These exams are the only requirements which every student must complete. Failure to do so will result in an Incomplete for the course.

  • You may receive a maximum of 50 points for Copper, Silver, and Gold (i.e. the material covered in Principles of Modern Chemistry.)

  • Antimony: If you earn 500 shekels at the Forum you will be awarded 4 wildcard points. These may substitute for any quiz (Mercury or Silver). Further information is provided at Rules and Regulations

The following table shows the number of points needed to earn each grade:

D55 Points
D+60 Points
C-65 Points
C70 Points
C+75 Points
B-80 Points
B85 Points
B+90 Points
A-95 Points
A100 Points

There are thus 167 points in play, with 100 required for an A (about 7 per week) and 55 for a D (about 4 per week).
