You won't spill any acid on the spectrometer in this lab. Choose solutions from the vast database and mix 'em together till the cloned cows come home. Marvel as the chemical solutions react in real time. http://www.merlot.org/merlot/viewMaterial.htm?id=83322 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.The latest, augmented version of VR Molecules, called VR Molecules Pro 1.1, is available online as well as in a stand-alone version (Mac and Windows).To view a video of the award winning author, go to View VR Molecules - Chemistry Award Winner 2007 video VR Molécules est un logiciel de simulation (en ligne et en mode local) permettant de visualiser et d'explorer les modes de vibration et de rotation des molécules (24 molécules sont disponibles).Il peut tout aussi bien être utilisé par le professeur pour préparer des démonstrations en classe, intégrer des animations (interactives ou non) dans ses documents HTML, que par les étudiants pour revoir les démonstrations présentées en classe et explorer par eux-mêmes la vibration et la rotation des molécules.La plus récente version (1.12) de VR Molécules, est accessible en deux versions : en ligne et en mode local (à télécharger, pour Mac et Windows). http://www.merlot.org/merlot/viewMaterial.htm?id=88586 An effective tool to help students learn about all aspects of the ideal gas law. One of the best web gas law simulations. http://www.merlot.org/merlot/viewMaterial.htm?id=74295 All you want to know about each element. a fourbar linkage http://www.merlot.org/merlot/viewMaterial.htm?id=404555 This is exactly what it says...a periodic table that comes alive. For each element that you click on, it'll give the name, picture, history, and everylittle thing you'll need to know about that element. It even has a media section to veiw different forms, images, and videos of that particular element. http://www.merlot.org/merlot/viewMaterial.htm?id=91119 Protein Explorer provides a user interface to the Chime plugin allowing easy manipulation and viewing of PDB structure files. Includes most RasMol commands and has a command line, but has buttons and menus for many useful commands. Includes a comparator funciton that allows comparisons between two structures, molecules in the structure can be selected in a sequence window and there is a non-covalent bond finder function. http://www.merlot.org/merlot/viewMaterial.htm?id=84217 3DMolSym is an educational program designed to visualize the symmetry elements of molecules and to animate the corresponding symmetry operations in an interactive 3D environment.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=83555 This tutorial/simulation consists of three topics. In topic 1, students look at the components of chemiosmosis in the bacteriumParacoccus denitrificans in which they step through animations of electron transport, proton gradient, and ATP synthase, learning the components involved in each.In topic 2, students construct chemiosmosis pathways in mitochondria and chloroplasts. Students will: 1) select the correct components (electron donor and acceptor, ETC, ATP synthase) and place them in the appropriate subcellular location ; 2) apply concepts about redox reactions, concentration gradients, and energetics to explain how chemiosmosis fits in a cell’s overall metabolism; and 3)summarize properties of chemiosmosis in organelles and Parcoccus denitificans. In topic 3, students follow the evolution of chemiosmosis and the role it played in the evolution of cellular life. Students will: 1) learn about chemical and cellular changes on early earth; 2) analyze efficiency of early forms of chemiosmosis; 3) compare mechanisms of non- and oxygenic photosynthesis; and 4) evaluate metabolic advantages of several endosymbiotic relationships. http://www.merlot.org/merlot/viewMaterial.htm?id=78863 A simulated experiment on qualitative analysis of the Group I cations. User may select solutions containing known cations, unknown cations as a trial experiment, or unknown cations as an assigned experiment. Results are graded in the trial mode. In the assigned mode, the results may be printed out to be handed in.Instructors may contact the author regarding the key for unknowns. http://www.merlot.org/merlot/viewMaterial.htm?id=74256 Explore the relationships between Volume, Pressure and Temperature that form the basis of the ideal gas law and the piston.
