I will give each student a letter grade for the course. The course grade will be based on grades on tests, homework, and class participation. However, the grade could either be private (given only to the student and his parents/guardians) or later sent to colleges the student applies to.この文章は自動翻訳されています

First semester of high school Chemistry 1: It is a 10-week online class that meets 3 times per week. In this course, I will cover: - Chemistry is useful and has practical applications: -- Chemists discover or create new medicines. -- Chemists test the water supply for dangerous contaminants. -- Chemists develop new products such as paints, cosmetics, and detergents. -- Chemists work in forensics. - Theories of the atom throughout history - Experiments that led to theories of the structure of an atom - Information you can get from the periodic table of the elements - Electron Configuration of a Neutral Atom of an Element - Valence (outer shell) electrons in an atom - Properties of Elements - Types of Chemical Bonds - ionic, covalent, metallic - Drawing Lewis structures of molecules - Polar covalent bonds and Nonpolar covalent bonds - Using VSEPR to determine shapes of molecules - Polar molecules and nonpolar molecules - Naming covalent compounds - Charge of an Ion - How to use the charge of each ion to write the formula of an ionic compound - Naming ionic compounds - Properties of ionic compounds - International System of Units (SI) - Significant figures - Dimensional Analysis (Unit Conversion) - Calculations involving mass, moles, density, molar mass, and percent composition of a compound - Intermolecular Forces of Attraction and How They Affect Properties of Substances - Solubility - like dissolves like - Exothermic and Endothermic reactions - Energy Diagrams of reactions - Factors Affecting reaction rate - Balancing chemical equations - Types of chemical reactions I will show PowerPoint presentations and a few short videos of experiments. My teaching style is enthusiastic and interactive. After talking for a few minutes about a concept and going over example(s), I put up a slide with a question or problem for the students to do. After the students work on the problem, I pick a student to give his answer. Then, I show a slide with the answer explained or worked out. I go over the correct answer thoroughly. I will give homework assignments and in-class, closed-book tests in this course. I will provide a formula sheet with some scientific constants that the students can use during some of the tests.
学習到達目標
Uses of chemistry in industry, etc. What experiments discovered electrons, protons, and neutrons. How the gold foil experiment led to the theory that an atom contains a dense, positively charged nucleus that is tiny compared to the atom's total volume.Where metals, nonmetals, and metalloids are in the periodic table. In the periodic table, elements in a group have similar chemical properties and the same number of valence (outer shell) electrons (exception is Helium).

Algebra I
Also, students should know how to cancel out common factors when multiplying fractions. However, I will review this topic briefly.
受講に必要なもの
Students must buy a 'LINKTOR Chemistry Molecular Easy to Learn Science Models & Kits with 136 Atoms, 1.76 lbs, 444 Pieces', $25.99 plus tax and shipping and handling cost - can be ordered from Walmart or www.amazon.com. During class, I will show PowerPoint presentations and a few Youtube videos of lab experiments using Zoom’s screen-sharing feature. I downloaded OpenStax 'Chemistry 2e' PowerPoints, and then typed additional information on many slides, and added many extra slides that I typed from scratch. At each class, as I go through a PowerPoint, I will explain each concept, give example(s), and put up question slide(s). I will ask a student to give his answer. Then, I will put up the answer slide and go over it thoroughly. According to openstax.org, "OpenStax is the world’s largest publisher of open education resources (OER)". OpenStax gave me permission to use their free PowerPoint presentations in my Outschool chemistry class. Each Youtube video that I will show has a Creative Commons license. Each person or group that made each of the videos agreed to let me show the video to my Outschool class. I will attach each PowerPoint presentation and Youtube video to a post or announcement in the Outschool classroom. This way, the students can view and study the PowerPoint or video outside of class time. I will attach each homework assignment to a post or announcement in the Outschool classroom. Each homework assignment will be a Word file with multiple choice questions. During some classes, I will attach a test to a post or announcement in the Outschool classroom. Each test will be a Word file with multiple-choice questions. Each student will download each homework assignment or test, type in his answers, save the file, and then re-upload their completed version of the assignment or test with his answers. Each homework assignment must be completed outside of class time. The tests will be in-class and closed book, but I will provide a formula sheet with scientific constants for some tests. I will show a video of the 'Effect of Catalyst on Reaction' experiment during class time. It is optional for students to do this experiment outside of class time. To do the experiment, a student needs hydrogen peroxide, small pieces of a raw potato, and a transparent, colorless glass (from the kitchen) to pour the hydrogen peroxide into. When the student is done looking at the bubbling mixture of hydrogen peroxide and potato pieces, each student should throw the liquid down the sink, and the potato pieces down the garbage disposal or in the trash.
使用する教材
Students don't have to consult any books, articles, websites or other sources. All the information that the students need to know will be in the PowerPoint presentations and in the short Youtube videos of lab experiments that I will show during classes. I will show the PowerPoints during each class period (except on test days). I downloaded OpenStax 'Chemistry 2e' PowerPoints, and then typed additional information on many slides, and added many extra slides that I typed from scratch. According to openstax.org, "OpenStax is the world’s largest publisher of open education resources (OER)". OpenStax gave me permission to use their free PowerPoint presentations in my Outschool chemistry class. I will show several short Youtube videos during the entire course. Each Youtube video that I will show has a Creative Commons Attribution license (reuse allowed). Each person or group that made each of the videos agreed to let me show the video to my Outschool class.

- TEACHING LICENSE: Permanent Non Tax Certificate from Ohio Dept. of Education
Teaching Experience:
I taught chemistry, other science, and statistics at high schools.
At main and branch campuses of universities and community colleges, I taught intro and advanced college Chemistry lecture courses (about 30 times) and lab courses (over 35 times) including organic lab and intro biochemistry lab. At main and branch campuses of universities and at community colleges, I taught Algebra I and Algebra II more than 25 times, a ‘Math for Education Majors’ course twice, and a course that covered Probability and Statistics, some logic, and routing problems. Currently, I am an Academic Tutor for math and science at the branch campus of a university.
Experience Working as a Chemist:
- I worked at two companies as a chemist.
- After I got my Ph.D., I did postdoctoral work in chemistry at both Cornell University and at CARB (now called Institute for Bioscience & Biotechnology Research, University of Maryland).
