Presents four probability problems, their simulations, and analyses. The first illustrates a discrete situation for which it is possible to list the sample space. The second and third are continuous--the number of possible outcomes is infinite. The last is discrete with a surprising continuous extension question which leads to l/e. (JN)

This high school physics computer software resource is a systems and control simulator that covers the topics of electricity, electronics, mechanics, and programming. Circuits can easily be simulated on the screen and electronic and mechanical components can be combined. In addition to those provided in Crocodile Technology, a student can create…

Describes software, hardware, and devices that were designed to provide students with an environment to experiment with basic ideas of mechanics, including nonlinear dynamics. Examines the behavior of a Lorenzian water wheel by comparing experimental data with theoretical results obtained from computer-based sensors. (MDH)

This high school physics resource is a simulator for optics, electronics, force, motion, and sound. Students can study oscillations, look at sound waves, and use probes to graph a wide variety of quantities. Over 100 activities are pre-written, and students can easily create their own additional activities using the multimedia editor. (WRM)

This high school chemistry resource is an on-screen chemistry lab. In the program, students can experiment with a huge range of chemicals, choosing the form, quantity and concentrations. Dangerous or difficult experiments can be investigated safely and easily. A vast range of equipment can be set up, and complex simulations can be put together and…
