This is a great website that was forwarded to me by a friend.  Broaden students' scientific communication skills by condensing the descriptive chemistry of an element down to a haiku.

A neat site that quizzes you on chemical symbols (e.g., Ag for silver), and donates rice for right answers. Hey, if students are going to learn chemical symbols, they may as well do it in a game setting, and many will find it a touch less pointless if they're doing someone else some good at the same time.

This website provides access to many formulations of the periodic table over time. I think that looking at the various representations of the table would provide an excellent way to discuss periodic trends.

This list was compiled by Mark R. Leach and is part of his free resource, The Chemogenesis web book.

I developed this Jmol page to help my students see the relationship(s) between the ligands and metal d-orbitals in a number of different geometries.  Since the images are all rotatable, students who have difficulty looking at flat images and drawing appropriate conclusions have that barrier reduced or eliminated.  I have now used the application twice - this past fall in the second semester of introductory chemistry and a few weeks ago when I began ligand field theory in my inorganic course.  In both classes I received favorable comments.  A number of students in the inorganic course, who h

This is my all time favorite resource for finding out basic information about the elements. I love it. And all of my students do too.
