In this course, we will explore water for its vast ability to grow crystals and importance to the environment and living systems. Hydrothermal methods can be used for synthesis of nanoscale to large industrial-sized crystals, and many minerals found in the earth grow under these conditions. Ocean vents, found deep in the anaerobic ocean floor, support unusual biological systems and mineral growth. Many technologies and scientific research connect to hydrothermal chemistry, which you are encouraged to explore according to your interests.
Learning goals for this course are broken up into the following:
· Fundamental properties of water and the technologies that use it;
· Understanding the role of water in the environment;
· Study of hydrothermal conditions and growth of crystals;
· Practice of informal presentations based on literature articles;
· Compiling related materials into a debatable thesis for a short research paper.

Student Conduct Code
As noted in the Student Conduct Code: ''Responsibility for good conduct rests with students as adult individuals.'' The policy on student academic misconduct is outlined in the Student Conduct Code- Academic Misconduct Policy in the online Student Handbook
In addition to these brief lectures, reading will be assigned for discussion. In addition, approximately every other week, you will also be presenting articles for 6-8 minute “Chalk Talks”.

Chalk Talk Guidelines
Each person will present an 6-8 minute oral presentation related to a reliable non-encyclopedic source, ideally a scholarly article from a peer-reviewed science journal. You may use up to 2 Powerpoint slides for: a) citation information; and b) any complicated structures, pictures or graphs that you may not wish to draw on the whiteboard. The majority of the talk will be presented on the whiteboard. You may use notecards. Reading from the original paper and/or notecards is strongly discouraged. Your presentation should include:
· Title of the article
· Reference (author, journal name, volume, year, page numbers)
· Outline of presentation
· Summarized abstract
· Background information and importance of the work
· Purpose of the article
· Structures of relevant molecules or materials
· Experimental details
· Conclusions drawn by author/researchers
· Before choosing an article, do not read the whole thing. Use abstracts and scan the remainder of the paper to see how appropriate it is for you.
· Once the article is chosen, scan it and search for main points: purpose, experimental, discussion/conclusions. Take notes.
· Armed with the main points, read more specifically on each of those. Take notes.
· Read the experimental section carefully, using any additional sources to educate yourself on the techniques. Take notes.
· Begin putting your outline together based on your notes.
· Practice, preferably with a friend, concentrating on timing, content and flow.
