The PhET Interactive Simulations project (http://phet.colorado.edu) has developed a suite of over 30 chemistry simulations, which are used world-wide. The simulations provide interactive environments in which students learn through scientist-like exploration and experimentation. The simulations emphasize the connections between real-life phenomena and the underlying science, make the invisible visible, and include visual models that experts use to aid their thinking. PhET’s design principles draw upon cognitive research on how people learn, discipline-based research on student difficulties, and research on simulation design. In this presentation, we will discuss the PhET design principles and processes, highlighting new design features and research around our growing suite of simulations in HTML5. Our new HTML5 simulations run in the web browser, enabling simulation use on tablets (such as iPads) and Chromebooks. Additionally, we will provide ideas for using PhET in a variety of education environments.

Probeware has been used in high school chemistry laboratories to support student investigations through easy data collection and analysis. These tools can help students measure and make sense of the macroscopic changes they observe. PhET Interactive Simulations, http://phet.colorado.edu, enable microscopic investigations using multiple representations and particulate visualizations for data analysis and conceptual understanding. In this talk, I will present how the combination of these two technologies used together can help students build a more comprehensive understanding of dynamic systems. For example, students can design experiments to investigate the relationship between temperature and pressure in the macroscopic lab using a pressure probe and the graphical analysis tools provided by the probe software. Using the PhET Gas Properties simulation, students can design similar experiments in a nanometer size environment while visualizing animated gas molecules. I will discuss several complementary probeware and simulation pairings that I use in my high school chemistry classroom, as well as resources and best practices for others interested in using probeware and simulations together.
