Organization of the CHEM 210 Course
The title of this course "Modern Applications of Chemistry" embraces the fact that there are essential underlying principles that can be found in what seem to be radically complicated systems. Much of Modern Chemistry appears to be quite different from what you have seen in prior chemistry courses, but at the end of this course you should begin to see how even complicated systems can be interpreted through essentially simple concepts and models.
This course is assessed in two main ways: Formative and Summative assessments. Formative Assessments are meant to be a place where you receive detailed feedback to help you to improve and to master certain critical ideas - things we call " Core Goals " in this course. There are 7 Core Goals listed below.
Additionally, There will be two midterms and one final exam that will focus on approximately 1/3 of the material each. It is important to note that the last third of the material is on applications of the prior 2/3 of the course in new situations, so it very much still will seem to be cumulative. These summative assessments will evaluate your ability to demonstrate your ability on longer more complicated problems, as well as on basic Learning Objectives.
Formative Assessments for Demonstrating Skill on Core Goals:
Instead of a Homework or Quiz grade that gives points based on effort or ability, you will be given multiple tries to try to pass each of the Core Goals above. Your work will be graded on a rubric and be given either a mark of "M" for Meets Expectations or an "N" for Not yet. The schedule for these assessments is below:
| Core Goal Attempt Date | First Attempt | Second Attempt | Third Attempt | Duration |
|---|---|---|---|---|
| Thur: 5/18/2023 | ( MAT ) | — | — | 30 min |
| Tue: 5/23/2023 | MAT | — | — | 20 min |

Note that only two attempts at the APP Core Goal attempts are given as these are cumulative applications of other materials. They are slightly longer than the others and time has been allocated for those. Note that the APP Core Goal is the 7th of the 7 goals, and is really intended to distinguish between an A- ability and an A ability in the course demonstrating an in-depth understanding of the applications of the other 6 Core Goals.
You only need to earn an "M" on a Core Goal ONCE. Once you have received a mark of "M" then you do not need to study for, nor take the subsequent attempts at that Core Goal!
Your grade on the Core Goals will be determined by the following Rubric:
- Earning an "M" on all 7 Core Goals: 100%
- 6 out of 7: 95%
- 5 out of 7: 80%
- 4 out of 7: 65%
- 3 out of 7: 50%
- 2 out of 7: 35%
- 1 out of 7: 20%
- 0 out of 7: 0%
Summative Assessments: Midterms and Final
The course has three summative assessments: Midterm I, Midterm II, and the Final Exam. Note that the Final Exam is the same duration as the standard exams (~1.5 hours), and just like the other exams, will have the time allotted at the end for Core Goal Assessments (recall that if you already met the Core Goal with an "M", then you will not need to stay to complete an additoinal attempt).
| Midterm I: Matter and Interactions | Midterm II: Solutions and Electrochemistry | Final Exam: Applications of Modern Chemistry |

Lecture 1: 5/17/2023
Introduction to each other and general goals of the course were discussed. The full walk-through General Chemistry prior knowledge was done focusing on energy, scale, and the way matter and electromagnetic radiation interact with each other. The conceptual focus for this lecture was on: Scale Matters. Think about waves of light (electromagnetic radiation), waves of matter (electronic orbitals), and the Coulombic interaction of these as the basis for understanding interactions. Moving charges have electromagnetic properties. The nucleus has charged particles (protons) so changing the number of protons greatly changes the reactivity and properites of an atom. Electrons have a charge and a very much lighter mass, so they have larger space to occupy with their wavelengths (based on deBroglie's wavelength equation). A review of the components of the atom was highlighted and the chart of Nuclides to discuss stable vs unstable nuclei. Nuclear reactions were discussed and how to balance them. Finally, a discussion of Einstein's famous equation \[E=mc^2\] was shown to be the source of immense amounts of energy from the Mass Deficit when nucleons combine to form atomic nuclei.
