This Java applet allows the user to name any two points in a Cartesian system, see the segment on the screen and view how the distance between the two points is found.

A java applet that helps a student to create a scatter plot using the coordinates and axes and given data.

An interactive Java applet which allows the user to investigate the path of light through a lens shape object. The shape of the object, the index of refraction of the material, and the location of the incident rays can be altered.

Students can download pattern block grid paper or cutouts for class activities. Included is an activity comparing the relationships of fractional parts called, "What's My Number?" Links available to other pattern block and fraction...

Students can use this applet to explore different 3-D objects. Different objects can be chosen, rotated, and viewed from a variety of sides. [Requires Java.]

Drawing a perfect ellipse with pins and string is demonstrated with a java simulation.

Chinese-language Java applet illustrating Fermat's principle that light follows the fastest path between any two points. Excellent animation and accompanying text. Relates Fermat's principle to Snell's law.

An interactive Java applet game in which the reflection of light is compared to the path of a billiard ball. Users view images of a target ball and try to direct a cue ball in such a manner as to hit it.

A Java applet which allows the user to emulate a refracting telescope and a light microscope. This is a great site to get information on the subject and better understand it through diagrams and charts.
