Students explore questions which cannot be handled with simple pendulums, and examine both the usefulness and the limitations of approximations in science. A Java applet created from a Stella model is included.

Eighth graders investigate linear equations.  For this Algebra I lesson, 8th graders explore the effects that manipulating a linear equation has on the graph of the function through the use of a java applet.

Eighth graders draw right triangles and identify the parts of a right triangle: right angle, interior and exterior angles, hypotenuse and legs. They predict and identify any relationships that exist between the sides of a right...

Students investigate the Sierpinski triangle and calculate the ratio and area of the triangle. In this fractals lesson plan, students calculate parts of a Sierpincki triangle. They use Google Earth to help them construct the different...

In this biology worksheet, students complete a crossword puzzle with 35 questions about reptiles. They identify the different types of reptiles.

Students predict the shape of a geometric figure in 3D. In this geometry lesson, students construct 3D shapes to perfect their knowledge of measuring and predicting. This assignment is also available as an online interactive lesson.

Learners rewrite equations using algebraic symbols. In this algebra lesson, students graph linear equations using the slope and y intercept. They make predictions about their graphs and analyze the results.

Students examine the influence of the end wall. They find a basin size and wind speed such that a given wall height is overtopped. Then, increase the wall elevation until overtopping stops. Students explain the difference in results.

In this chemistry worksheet, students complete an online calculation focused upon the Law of Gases. The sheet requires the right kind of internet browser.

This resource presents an internet directory of resources for Java programmers.

Finally, an interactive Sketchpad for geometry that is free! Students are able to understand various theorems, definitions, and objects through observations and explorations using an interactive applet.

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.

A good site that begins with the background and branches into the structure, function and applications of technology. This version of the page requires Java, and should open some applets that allow you to see the structures in 3-D.

Molecular Expressions at Florida State University offers a java applet to show the a working AC generator.

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.
