Introduction to Tidepool Biology for Citizen Scientists

Introduction to Tidepool Biology for Citizen Scientists

What are tides, what causes them, and what are tidepools? Why they are important, and how can I become a citizen science and contribute my observations to science?

Course Description:

This course is an introduction to what tides are, what causes them, what tidepools are, why they are important, and how you can become a citizen science and contribute observations to science.

Conduct of the Course:

Each module includes an introduction, reading assignments, and a quiz.  Unless stated otherwise, each module includes all the assigned reading materials. You are to complete the modules in order, working at your best pace.

Some modules will also include recommended readings. These will not be covered on the quiz, but we strongly recommend that you at least look them over, as they will often include more detailed or advanced information. However, some recommended reading gets a bit technical. If recommended readings are above your current level, don't worry. But do download it for future reference.  

On a few occasions, modules will include "reference" items, which you should download and keep handy where you can refer to them as needed. 

For each module, complete the assigned readings and then take the quiz. Each quiz has twenty questions. To pass, you need a score of 14 (70%) or higher.

Quizzes are "open book" and may be repeated.

No grade will be assigned; the course will issue a certificate on a pass/fail basis to students who pass all of the module quizzes.

Tips and Suggestions:

There will be a lot of reading in this course. You may proceed at your own pace, but we strongly recommend that you study regularly and often. Don't let too much time go by between study sessions; try to complete at least one module each week.


Completion of CS 101, Introduction to Citizen Science is recommended, but not required.
