Censorship in the Libraries
-
"All of us can think of a book that we hope none of our children or any other children have taken off the shelf. But if I have the right to remove that book from the shelf -- that work I abhor -- then you also have exactly the same right and so does everyone else. And then we have no books left on the shelf for any of us." --Katherine Paterson, Author
-
Write a persuasive essay to a newspaper reflecting your vies on censorship in libraries. Do you believe that certain materials, such as books, music, movies, magazines, etc., should be removed from the shelves if they are found offensive? Support your position with convincing arguments from your own experience, observations, and/or reading.

Welcome to the edX Demo Course Introduction. This is where you can explore how to take an edX course (like this one). Most courses have an "intro" video that shows you how it all works.
-
You can watch the introduction video (below) or scroll though the course studies and assignments using the toolbar (above). Just for fun, we'll keep track of your work in this demo course, and show you your progress in the toolbar just like in a real course.
-
Watch the overview video (below), then click on "Example Week One" in the left hand navigation to get started.

Molecule Editor
-
A lot of students love the molecule builder. It makes creating and visualizing molecules rather easy. A chemistry professor may have you build and submit a molecule as part of an exercise.
In this problem you will edit a molecule using the molecular drawing program shown below:
-
-
-
-
-
Are the molecules I've drawn chemically possible?+ open
-
-
-
-
The chemical editor you are using ensures that the structures you draw are correct in one very narrow sense, that they follow the rules for covalent bond formation and formal charge. However, there are many structures that follow these rules that are chemically impossible, unstable, do not exist in living systems, or are beyond the scope of this course. The editor will let you draw them because, in contrast to the rules of formal charge, these properties cannot be easily and reliably predicted from structures.
-
If you submit a structure that includes atoms that are not possible or are beyond the scope of this course, the software will warn you specifically about these parts of your structure and you will be allowed to edit your structure and re-submit. Submitting an improper structure will not count as one of your tries. In general, you should try to use only the atoms most commonly cited in this course: C, H, N, O, P, and S. If you want to learn about formal charge, you can play around with other atoms and unusual configurations and look at the structures that result.

The JME molecular editor is provided courtesy of Peter Ertl and Novartis; the licence can be found here.
The protein builder allows you string together the building blocks of proteins, amino acids, and see how that string will form into a structure. You are presented with a goal protein shape, and your task is to try to re-create it. In the example below, the shape that you are asked to form is a simple line.
