Each week, in the online classroom, you:

Engage in an online discussion to answer specific questions.
- This will help you learn by sharing and growing your knowledge in the company of other students.
- You must begin contributing to the online discussion by Thursday afternoon each week, and post in the discussion on more than one day.
Take the quiz question you are assigned for the week, research the topic, and write down what you think the answer is. Explain why, in rational and geological terms, you think your choice is the answer to the question. In the quiz question discussion, you can read and discuss students' answers to the other questions as well, and thereby prepare to ace the post-quiz.

In the quiz question discussion, and the general weekly discussion, you must cite your information sources. In fact, this is required any place and any time that you present texts or images for this class.

Your contribution to the quiz question discussion is due on Thursday by 5:00 PM.
Take and submit the lab preview quiz for the week by the time lab begins. (The lab preview quiz goes offline at that time.) The lab preview quiz is in the Lab Folder. It consists of five multiple-choice questions. To be able to answer the questions, you will need to have read the Lab Web page (also in the Lab Folder), which introduces you to the lab you will be doing this week, and any Basics pages linked to in the Lab Web page text.
At the end of the week or over the weekend when you have time, take the post-quiz, which has a mixture of exactly the same questions and reworded versions of the same questions as were on the pre-quiz. Use the Quiz Question Discussion as a study aid before taking the post-quiz.

Take the post-quiz for this week between the end of lab Thursday (12:00 noon) and the first class the following week (10:00 Monday).
At the end of the week or over the weekend when you have time, take the pre-quiz for the next week. You are not expected to know the answers on pre-quizzes. While it will be of interest to see how much you already know, and you must answer each question on the pre-quiz to the best of your knowledge, you will nonetheless get credit on the pre-quiz for taking it, whether or not your answers are correct.

Just like the post-quiz of the week ending, take the pre-quiz for the next week between the end of lab this Thursday (12:00 noon) and the first class the coming week (10:00 Monday).
