myPhysicsLab is a site with interactive physics simulations, such as springs, pendulums, roller coasters and collisions. Simulations animate in real time and can be manipulated by dragging objects or changing parameters like gravity. Setups can be shared by URL, and numeric data can be obtained from simulations. The software is open source under the Apache 2.0 License, with source code on GitHub.
A virtual museum of pure chemical elements from the periodic table, with images and information published under a Creative Commons license. It includes a periodic table linking to element pages, plus games, calculators, and a simulation.
Stellarium is a free open source planetarium for computers. It shows a realistic sky in 3D, as seen with the naked eye, binoculars or a telescope, and offers time control, telescope control and a plugin system. The site describes it as easy to use and provides a features list and system requirements.
The WebQC Balance Calculator is an online tool for balancing chemical equations, offering step-by-step solutions by inspection and by the algebraic method. It also reports reaction type, stoichiometry and limiting reagent. Users enter an equation or reagents and click to balance.
The Useful Tropical Plants Database contains information on the edible, medicinal and other uses of several thousand plants grown in tropical regions. It is a work in progress, with records added and updated regularly. It currently lists 13362 species, and information is fully referenced.
A project for an amateur-built liquid fueled rocket engine and flight vehicle, with a site covering engine designs, igniters, a rocket, test stand and software. A launch of Rocket 1 reached 10,800 ft after about 10.5 seconds of engine run time.
WebElements presents the periodic table of the elements. The table arranges the chemical elements by atomic number so that periodic properties are made clear, and each entry gives the element's symbol, atomic weight and name.
