It is aimed to help chemistry students conceive the symmetry properties of the molecular structure. 3DMolSym includes a database with symmetry and geometry data of 48 organic and inorganic molecules, corresponding to all point groups of chemical interest. http://www.merlot.org/merlot/viewMaterial.htm?id=404935 A variety of Organic Chemistry Laboratory techniques are covered in a series of online tutorials, including Crystallization, Melting Point, Extraction, Distillation and Thin-Layer Chromatography (TLC). Each fully narrated lesson presents an introduction to theory and videos of laboratory demonstrations. The lab demo videos include an introduction to the glassware and materials needed, the experimental set-up, a discussion of safety concerns and common mistakes, a demonstration of actually running the experiment, and an analysis of the results. http://www.merlot.org/merlot/viewMaterial.htm?id=547107 What do you think of this resource?

Both in-class polling software and online lectures are used as part of a comprehensive teaching strategy, designed to enable students to develop critical thinking and analytical skills. While in-class polling is not an online process, it is included within this case study to highlight how different types of technology can be used together to effectively support classroom teaching, when integrated with a carefully considered pedagogical approach. http://www.merlot.org/merlot/viewMaterial.htm?id=380175 This video demonstrates how to use VR Molecules and describes the benefits of using it in chemistry courses. VR Molecules presents dynamically and interactively the vibration and rotation modes for 24 molecules (out of a more extensive list) containing up to twelve atoms. It allows the user to create and save on his or her hard disk documents containing, much in the same way as Power Point presentations, up to 10 "pages״, each featuring one or two molecules with specific parameters (viewpoint, active modes, etc.). These presentations can be made available through the Internet, with optional sound and text explanations associated with each page. http://www.merlot.org/merlot/viewMaterial.htm?id=376895 This page is maintained by Alistair B. Fraser in an attempt to sensitize teachers and students to examples of the bad science often taught in schools, universities, and offered in popular articles and even textbooks.
