science by simulation

Welcome to Science By Simulation. We are enabling modern science education through innovative software tools based on modeling and simulation techniques. These tools are designed to be incorporaterd into undergraduate and high school courses in both pure and applied sciences, allowing students and teachers to turn their computers into powerful virtual labs and analytical platforms. Our initial offerings are in the areas of chemistry and life-cycle assessment. Additional tools are in development and will be released in time for the 2017-18 academic year.


Latest news:

  • June 13, 2017: ChemReaX is now listed in these two major databases for online educational resources: National Science Digital Library and MERLOT. And also on the ChemCollective site as an online chemistry education tool.

  • May 18, 2017: Just added two new nifty features to ChemReaX, making it easier than ever to set up and simulate chemical reactions: searchable dropdown lists to quickly select reactants and products, and automatic balancing of chemical reactions.

  • March 22, 2017: The new reaction selector in ChemReaX provides a menu of over 80 pre-defined chemical reactions for a quicker start to virtual chemistry labs in undergraduate and high-school AP/IB courses. Plus, users can construct a virtually unlimited variety of chemical reactions using the 1200+ species in the database to experiment with thermodynamics, equilibria, kinetics, and titrations.

  • March 7, 2017: New article in Chemistry Solutions explains how virtual labs designed around ChemReaX can enable students to take an investigative and experimental approach to learning chemistry: Using Virtual Labs to Enhance the AP Chemistry Curriculum

  • February 12, 2017: Five new tutorial articles are available that demonstrate how ChemReaX can be used as a virtual lab in general chemistry and physical chemistry courses in undergraduate and high-school AP programs.

  • January 1, 2017: New version of ChemReaX is now live on the cloud with several enhancements including pressure settings, reaction rate modeling and simulation of acid-base titrations. This is a free chemical reaction simulation app for chemistry students and teachers at the undergraduate and high school (AP) levels.

  • November 8, 2016: ChemReaXTChemReaX has been added to the American Chemical Society's list of recommended software/websites for virtual chemistry and simulations.

  • September 29, 2016: ChemReaXTis now available through the LibreTexts project at UC Davis.
