Bohr Atom: a real-time simulation of a hydrogen atom designed according to Bohr's Theory. It uses a graphical display to demonstrate atom behavior.

BK Periodic Library: This interactive periodic table gives you an in-depth look at the elements that make up our earth, the solar system, and the galaxy. Search for elements by name, symbol, or property; view periodic trends with the built-in graphing program; or change the temperature interactively and watch the elements adjust their properties.

Crocodile Clips 3 Elementary: introduces the basics of electricity, sound, and mechanics. Use ready-made worksheets or design your own circuits and simulate them. You can create virtual experiments from a variety of components, whose values can be changed with the click of a mouse. Animation reveals invisible concepts such as voltage, force, torque, current, and charge. Motors turn, masses accelerate, springs oscillate, and lamps light up. Electrical experiments include internal resistance, Ohm's law, Kirchoff's laws, measuring resistance, and power in electric circuits. Sound experiments include period and frequency, beats, intensity and amplitude, and interference. Mechanical experiments include Hooke's Law, speed acceleration, Newton's laws, combining forces, motion around an axis, rotational inertia, work and energy, kinetic energy, conservation of mechanical energy, and many more.

ChemBalance Wizard: accepts up to ten chemical species as input and produces one or more balanced chemical equations. If no balanced equations exist for the given species, you're informed that none can be produced.

Force: a virtual physics laboratory allowing users to define systems of particles with mass, charge, radius, position, and velocity. The system can then be animated--using gravitation, Coulomb's law, and collisions--to show how the particles will move.

Physics Collisions: This is an oblique collisions simulator that simply shows balls interacting with oblique collisions. From a physics point of view, it demonstrates principles such as conservation of momentum, restitution, and energy. Physics Collisions provides a good simulation of the ideal gas laws and the gas constant. You can change gravity or mass of the example particles.
