Chemistry A

Course Description

Uses the ASKME® model to introduce chemistry as the study of substances and their reactions. Covers laboratory practices, measurement, atomic structure, the periodic table and trends, nuclear chemistry, writing formulas, naming compounds, physical and chemical reactions, chemical bonds and molecular geometry. Students will use activities and laboratory exercises to further enforce basic Chemistry concepts.This is a laboratory course.

Required Course Materials

We are temporarily unable to supply you with a science kit for this course. However, you can create your own lab kit by assembling the needed materials. You will find the list of lab kit materials here. You will need some common household materials for the labs in this course. You can find that list of materials in the Resource Center of your course; it’s called the Lab Grocery List.

Course Organization

Chapter Movies. These animations will show you a problem that you will learn about throughout the unit.
Activities. The Activities are practice assignments. Each Activity is a non-graded exercise that allows you to build your knowledge and identify your strengths and weaknesses. Generally, the Activities consist of:
  Introduction: A short introduction to the Activity.
  Review Exercises: Short review assignments that you submit for a grade. These are required and must be completed to finish the course.
  Tutorials: Animations that teach concepts and ideas.
  Guided Practice Questions: Questions to answer with the help of hints.
Graded Assignments. Graded Assignments are the tasks you will submit to your instructor for a grade. Each assignment contains specific information about how your work will be assessed and how credit will be given for your responses. The average of your assignments will count for 75 percent of your course grade.

Final Examination

The final examination is comprehensive; it covers the material from all of the units. To pass the course, you must receive a grade of 70 percent or better. You can apply to take the Final Exam after 100 percent of your graded assignments have been submitted, and at least 70 percent have been graded and returned to you.
Format: Multiple-choice, short answer
Time Allowed: 3 hours
Materials Allowed: 2 pencil, graphing calculator, computer-graded answer sheet provided
