In high school chemistry classes, the ability to visualize dynamic sub-microscopic particles (atoms and molecules) is especially important because the behavior of such particles is used to explain macroscopic phenomena (e.g., ice melting). Under a previous IES Goal 2 Development grant (R305K050140), the researchers developed six simulations in four high school chemistry topics: kinetic molecular theory, diffusion, the behavior of ideal gases, and phase change. In the process of designing, de...
