In the past Vernier used to develop computer simulation software. We currently focus on sensors, software and curriculum to facilitate real-world data collection in the classroom.
There are many sources available for science simulations and they keep changing. There are also non-simulation options for computer-based activities. Here are just a few options:
Pivot Interactives
Owned by Discovery Education, Pivot Interactives provides videos of real-world and laboratory phenomena for students to measure. Measurement takes a variety of forms. A hallmark of the activities is the multiple videos which allow students to change one variable at a time and perform an inquiry experiment. Student and instructor videos can be uploaded to the platform.

ComPADRE
ComPADRE is a collection of teaching resources hosted by the American Association of Physics Teachers (AAPT), and includes some simulations for physics.

NASA Kids’ Club
NASA offers interactive games (for Grades K-4) on the solar system, rockets, addition, “guess what number I’m thinking of,” and NASA spinoffs (everyday items developed from NASA research). A teachers’ area links to guides for teaching about clouds, precipitation, energy, winds, weather, planetary geology, flight, the Wright brothers, rockets, the electromagnetic spectrum, and careers. http://www.nasa.gov/kidsclub
Ology
The American Museum of Natural History (part of the Smithsonian Institution) provides this fun site for kids. Find readings, videos, games, and hands-on experiments relating to a variety of topics at this site.
