Welcome to our site for science interactives for building theory through simulation! This section of our website features a collection of HTML5 interactive pages that allow a user to explore science concepts. The interactive simulations are intended to be used by the individual student or learner who is attempting to further understand the concept. We also provide editable versions of each of the models so students or teachers can remixed and repost their own versions of the simulation or domain specific block-based programming environments to suite their own needs. Below explore the first two environments we have built in this series, Thermal Equilibration and Disease Spread. To use them, click on the phenomenon button: either "Thermal Equilibration" or "Disease Spread". Inside the model, explore the phenomena, and our custom programming environment. After exploring the model, try out the "Editable Model", to customized your own version of the model! All of the interactives are NetLogo simulations built in NetTango which allow a user to manipulate an environment and observe the effect of changes upon the simulation. Additionally, with NetTango, a user can use a custom built, domain specific, blocks-based programming environment to rewrite the simulation to explore how the phenomena work.
