Whether you are looking for a visual and interactive way to teach the Ideal Gas Law, or are struggling to understand it yourself, this is the site for you. This interactive Java applet allows you to manipulate all components of the Law, while visually displaying the effects that the changes produce in the gas. A "Guided Inquiry Activity" provides a series of "laboratory" experiences designed to demonstrate the aspects of this law, making the site a well-rounded resource for students and teachers.

This site draws students into solving problems in a simulated chemistry laboratory environment that is engaging and realistic. Just like they do in many of our colleges, students checkout reagents and equipment, and then proceed to a wet lab where they mix and titrate solutions at a workbench. This realistic site can augment a wide range of learning activities both in and out of the classroom, and provides excellent documentation for students unfamiliar with working in the chemistry laboratory.

This site provides a wealth of data such as element history, uses, geology, biology, reactions of the element, compounds, bond enthalpies, radii in compounds, lattice energies, reduction potentials, electronic configurations, ionization energies, electron affinities, electronegativities, effective nuclear charge, electron binding energies, atom radii, valence shell radii, bulk properties, thermal properties, thermodynamic properties, crystal structure, NMR, naturally occurring isotopes, radioisotopes, and even a compound index!

VR Molecules is an online simulation presenting 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 one's hard disk documents containing, much in the same way as a Power Point presentations, up to 10 "pages", each featuring one or two molecules with specific parameters (viewpoint, active modes, etc.). VR Molecules Pro can also be used to make one's presentations available through the Internet. One can also associate sound and text explanations to each page of an online presentation, thus creating a full-fledged multimedia document.

3DMolSym is a molecular visualization 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 searchable database with symmetry and geometry data of 48 organic and inorganic molecules, corresponding to all point groups of chemical interest.

This web site is an interactive periodic table that is amazingly comprehensive with a vast array of high quality data about every element. This is the most useful and effectively designed web site associated with the periodic table that has been entered into the MERLOT collection.
