Chemistry Professor Overview: Chemistry professor is a website that sells DVD's and chemistry notes intended to help a chemistry student. The website was recommended to me by my chemistry teacher from high school if I ever need good, extra material. I used his DVD's to study for the AP exam, and they were extremely valuable. They presented content in a unique way, however free general chemistry information can be just as good, such as the other website evaluation I submitted, General Chemistry Online. Content: The site's purpose is easy to determine, and it's also easy to determine the site is not free. The information is cited in the DVD's themselves, but not on the website. The courses offered by the site are well-organized and it's easy to determine what information will be covered in each course. The information quality is very good, and more in-depth than free informational websites. Somebody could learn enough chemistry to be almost as proficient as through college courses. Design: The site's design is minimal, and uses a simple color palette that makes information easy to see, and the site easy to navigate. Checkout directions are easy to follow, and are secured through PayPal. Information is current and well-presented, and the authors are available for contact through phone or e-mail.

American Chemical Society Overview: The website is for all chemists, including members of the American Chemical Society, chemistry teachers, and students as there is chemistry information as well. There is also a 'new and research' scrolling bar that includes scientific news other than chemistry, as well as 'molecule of the week.'  Content: The site's purpose is not clearly defined at first besides that is is chemistry related. A little bit of digging is needed to find what a user is truly looking for, whether it is information on chemistry, chemistry careers, or the section for members of the American Chemical Society. The author and copyright date are easy to find. The education tab is very useful, providing links to science experiments for kids, programs for undergraduate and graduate students, workshops, and funding and awards for chemistry students. There is also funding for researchers and applications for having information published.  Design: The website's design is good, but has some holes. For one, the website does not load effectively in Internet Explorer, and the homepage does not load efficiently. The homepage has strong eye appeal, however it has a lot of information in a small space, and makes it hard to find or even determine what a user is looking for. The homepage's visual appeal and interesting sections such as 'molecule of the week,' 'cool science,' and 'everyday chemistry' make the site eye-catching and cause the user to stay and take a look around. 

General Chemistry Online Overview: General Chemistry Online is a website for general chemistry students intented to help students learn general chemistry basics thought FAQ's, featured articles, tutorials, and other tools. The article included are incredibly interesting, from a chemistry standpoint, and can spark interest in chemistry. There is also a Common Compound Library that has over 800 common compound names, formulas, and structures, which could be useful past general chemistry and into organic chemistry. Overall, the site is a very valuable tool.  Content: The site's purpose is easy to determine with a quick look at the home page. The information is liberally cited when necessary, and the author is qualified to be publishing such information. The sponsor is Frostburg University, and that is clearly identifiable. The information is current, as general chemistry does not change frequently or quickly. The content of the site is well organized, and it is easy to find the information you are searching for, as the homepage is somewhat of a table of contents.  Design: The design isn't fancy or even eye-catching, however it does not need to be. The design is simple, and easy to use to find the information desired. It was designed for an older audience learning general chemistry, and bright colors or fancy graphics would get in the way of information and be distracting. All of the internal and external links are working, and each section of the site and each link serves a clear purpose.
