## Your turn! Student Projects

As per the syllabus, 5% of your grade will be based on contributing a Rhea page on a subject related to the course. To pick a subject, simply write your group name next to it.

Notes:

- No more than one group per subject.
- Once a group has signed up with a project, this project is closed to other groups.
- A group cannot un-sign from a subject they signed up for. Signing up is permanent.

Your project page will be graded based on content as well as interactions with other people (page views, comments/questions on the page, etc.). The number of links to other courses and subjects will also be taken into account: the more the merrier! Do not simply copy the book and do not plagiarize. Read Rhea's copyright policy before proceeding.

For some lovely contributions, see Honors Project 2011 by Daniel Lee.

Deadline: Sunday before dead week. No changes after that will be taken into account.
