Just click the "interactive" tab on the top left menu and you can choose different simulations. It includes, the complete definition of parabolas, reaching beyond the ability to graph into the realm of why the graph appears as it does. It also has vivid descriptions of angles including circle angles for geometry. It also has calculators for principal nth roots, gdc, matrices, and prime factorization. It's definitely worth checking out. Quote from site: "A parabola is actually a locus of a point and a line. The point is called the focus and the line the directrix. That means that all points on a parabola are equidistant from the focus and the directrix. To change the equation and the graph of the interactive parabola below just click and drag either the point A, which is the focus, or point B, which controls the directrix." This is an interactive site that allows people to change the graph to understand why directrix and focus dictate parabolic graphs. http://www.merlot.org/merlot/viewMaterial.htm?id=74508 Converts a wide variety of units from one system to another. Quantities include length, area, volume, mass, flow rate, density, force, pressure, energy, etc. http://www.merlot.org/merlot/viewMaterial.htm?id=84013 Parts of a Compiund Microscope http://www.merlot.org/merlot/viewMaterial.htm?id=84108 Virtual Microscopes. http://www.merlot.org/merlot/viewMaterial.htm?id=81821 Students drill pilot wells to determine the subsurface geometry of an oil deposit. Different levels of difficulty. Each oil has cost. Possible fodder for experimental design problem. http://www.merlot.org/merlot/viewMaterial.htm?id=81820 Using a Landsat image, students must sample different points on the image to estimate the number of trees in a large tract of land. Possible fodder for an experimental design project. http://www.merlot.org/merlot/viewMaterial.htm?id=90070 An introduction to eighteen people who revolutionaized technology is presented through hour-long interviews by reporters and high school students. Each interview includes pictures, transcribed text, audio version, hyperlinks to many of the topics discussed, and a crossword puzzle based on the interview. http://www.merlot.org/merlot/viewMaterial.htm?id=74237 This applet animates 5 different sorting algorithms. http://www.merlot.org/merlot/viewMaterial.htm?id=74873 View AutoCad drawings saved using the dwf file format.
