PBS Learning Media
Collection of various science learning resources hosted by PBS LearningMedia. Covers topics such as physics, biology, and geology.
Dan Schroeder Physics Educational Software
Physics education software created mostly by Dan Schroeder, some excellent simulations in here.
States of Matter
Investigating molecules bouncing around in a piston in various states of matter. Good thermodynamics simulations by PhET.
Physics Simulations
Lots – hundreds at least – of small physics applets, around a wide range of topics, separated out into two semesters of college physics. Motion, thermo, EM, waves, and optics all covered. Created by Andrew Duffy.
Interactive Molecular Dynamics
Particle simulation that is great for exploring thermodynamics, or Newtonian mechanics, gas laws, etc. Created by Dan Schroeder.
Entropy Explained, With Sheep
Blog post about Entropy, full of interactive simulations. Written clearly and understandably, also with sheep. Created by Aatish Bhatia.
Fowler’s Physics Applets
Collection of small physics simulations, many including nice explanations. Built by Michael Fowler.
Falstad Gas
Particles bouncing around in a box, with lots of options for changing the setup. Includes thermodynamic quantities, too. Built by Falstad.
JavaLab
Just an amazing trove of science simulations built by middle school teacher, DJ Lee. I’m amazed at how much is covered here.
