Two noteworthy resources are Flash tutorials and an archived Problem of the Week section. The tutorials explain elementary calculus concepts and techniques. Each Problem of the Week is rated by difficulty with an accompanying detailed solution. Other features of note include the yearly Superbowl of High School Calculus, Calculus & Music, and calculus "Cheat Sheets." http://www.merlot.org/merlot/viewMaterial.htm?id=227507 This site is an interactive, introductory chemistry course. The content and explanatory material are designed for students in the health science field and high school. However, students enrolled in first semester college chemistry may find it helpful as a chemistry primer. Animations, video clips, and other interactive content are integrated into the course. Topics include:1. The Metric System2. Elements3. Compounds and Bonds4. Chemical Reactions5. Energy and Matter6. Gases7. Solutions8. Acids and Bases9. Organic Chemistry http://www.merlot.org/merlot/viewMaterial.htm?id=624761 Scientific data sets presented in the form of spreadsheets, image analysis, online mapping/graphing, data portals, and modeled data are used in exercises to investigate the climate, atmosphere, topography, oceans, and other aspects of the Earth. A few activities are listed below.Plate Motion Using EarthScope GPS DataAnalyzing the Antarctic Ozone HoleClimate History from Deep Sea SedimentsCool Cores Capture Climate ChangeDetecting El Niño in Sea Surface Temperature DataEnvisioning Climate Change Using a Global Climate ModelEvidence for Plate TectonicsExploring Air Quality in Aura NO2 DataExploring Characteristics of WetlandsExploring Monsoon Precipitation and Streamflow in a Semi-Arid WatershedHow Cities Affect Their Local ClimateLife in Extreme EnvironmentsTeaching notes/strategies, learning goals, appropriate grade levels, standards, and background information are given for each exercise. http://www.merlot.org/merlot/viewMaterial.htm?id=645858 An online surface chemistry course with emphasis on surface analysis techniques.Course chapters include:1. Structure of Solid Surfaces (Miller indices, fcc, hcp, and bcc structures, surface energetics, particulate metals, and relaxation and reconstruction processes)2. Adsorption of Molecules on Surfaces (Adsorption/Desorption)3. The Langmuir Isotherm4. UHV & Effects of Gas Pressure5. Surface Analytical Techniques (AES, XPS, UPS, IR, EELS, SIMS, TPD, TPRS)6. Overlayer Structures & Surface Diffraction (LEED and RHEED)7. Surface Imaging & Depth Profiling (SEM, SAM, XPS, SIMS, Auger, STM, AFM) http://www.merlot.org/merlot/viewMaterial.htm?id=645917 Real space lattice vectors can adjusted while the corresponding real and reciprocal space lattices are displayed. The three-dimensional real and reciprocal lattices can be rotated and magnified. Also, the real and reciprocal space lattice matrices are displayed. http://www.merlot.org/merlot/viewMaterial.htm?id=645086 Animation of the Gibbs Phase Rule for one component and two component systems. Various regions in the phase diagrams can be selected to show the relationship between the number of components, phases and degrees of freedom. http://www.merlot.org/merlot/viewMaterial.htm?id=622475 The Jules Verne Voyager has a wealth of interactive maps of solar system planets. The UNAVCO university consortium server compiles data to create maps using a Java applet.Planet and selected moon maps include information derived from satellite missions, impact information, latitudes/longitudes, and planetary features. A sampling of Earth maps include topography, crustal stress, tectonic plates, and development of the ocean floor. Moreover, maps can be overlaid. For instance, the Earth's fault lines can be be combined with earthquake, and moment tensor maps. Once created, maps can be saved in gif format or given a reference URL. Pan and zoom functions can be used on maps. http://www.merlot.org/merlot/viewMaterial.htm?id=637307 A ferromagnetic material's hysteresis loop is simulated as a function of coercivity, saturation field, and remanence. The change of magnetic domain order is illustrated throughout the hysteresis loop cycle. http://www.merlot.org/merlot/viewMaterial.htm?id=632889 The 32 crystallographic point groups are rendered by the Rayshade 3-D ray tracing program. Animated GIF movies and high resolution JPEG images may be downloaded and used to illustrate symmetries of the crystallographic point groups. The following article provides detailed information regarding the use of the three-dimensional point group renderings.Teaching crystallographic and magnetic point group symmetry using three-dimensional rendered visualizations http://www.merlot.org/merlot/viewMaterial.htm?id=645089 The simulation shows distortion of the strontium titanate perovskite crystal structure below a critical temperature. The second order phase transition created by oxygen plane rotation is shown with changes in entropy and Gibbs free energy plots.
