Course Overview

In this course you will learn about some of the important topics in chemistry. We will start with some essential math skills and use these to cover such topics as density, atomic structure, the nature of light, nuclear chemistry, molecular structure, moles, chemical reactions, and gases.

What to Bring to Class

  1. binder
  2. pencil or pen
  1. basic scientific calculator


The grading policy of Chemistry 3 is designed to reflect how much work you put into learning. If you put in the effort to learn the material you will do well. Your grade will be based on the following categories.

Missing Class

If you are tardy or miss class you must present me with an absence slip from the main office. This will clearly indicate whether it was excused or unexcused. If you come to class without one you will be asked to go to the office to obtain it.

If you miss class, and it is an excused absence, then you may make up the work you missed. You must see me before class starts or after it has ended and ask for the work. It is your responsibility to find out what you missed and to do it. You must complete the work no later than the due date plus the number of days absent or the usual late penalties will apply.

Late Work

Lateness is not acceptable unless you were absent and have shown me proper documentation to prove your absence was excused. Arrangements to hand in work missed when absent must be made at the first class meeting upon your return. Late work is subject to a penalty of 15 points on a 100 point assignment. Late work will be accepted only within one week of the original due date. After that it will not be accepted. Incomplete work handed in late will not be accepted. Key point: If you think you may not be able to avoid handing your work in late then speak to me at least one full day before the due date to see whether arrangements can be made.

Lab Safety

Safety is of paramount importance in the lab. Warnings of particular hazards will be given in the introduction to each lab activity. Students will be reminded once of safety rules. Students who do not heed such reminders will have to sit out the lab and take a zero.

Office Hours

I will be available after school Tuesdays, Wednesdays, and Thursdays. Also, I usually arrive at school by 7 am at the latest so seeing me before school for help is also possible. Advisory/AEAST is also a good time to see me.

If you are struggling, make an effort to come and see me. In my experience this one action can improve your understanding (and your grades) immensely.


One of the most important ways to improve your grade in my class is to do well on tests and quizzes. In order to encourage you to come in for help with your preparation I will offer 5% in extra credit points on a quiz if you come in at least once to study in my room during office hours and actively ask me questions. You must come at least one full day before the scheduled date of the quiz. This is a great opportunity to get together with friends to come in and ask questions and study together.
