Zitmus Makes School Science Something You Can Push Around
A free browser collection of 37 interactive physics and chemistry simulations organized around school science chapters.
Field notes
The collection is divided into 26 physics simulations and 11 chemistry simulations, with browsing available by subject and chapter. Demonstrations named on the homepage include Single-Slit Diffraction, Circular Aperture—Airy Rings, Crossing a River—Relative Velocity, and Ball on a String—Vertical Circle. The card system adds a visual indexing device: each subject receives a coloured cap positioned along an acid-to-alkaline indicator scale, allowing the grid to be scanned visually as well as by label.
