This app invites you to explore the relative motions of our solar system's planets, their moons, and several exoplanet systems. It is based on ideas presented in "A Little Book of Coincidence" by John Martineau. Are the amazing patterns created by these orbiting bodies just a coincidence, or is something more than that going on? Take a look and see what you think. Be sure to check out the special relationship between the Earth and Venus.
CloudLabs Solubility Constant

This simulation recreates the environment of a chemistry laboratory in which there is a flask containing copper sulfate, a flask with sodium hydroxide, a flask with hydrochloric acid, a flask with ammonia, two test tubes, a rack, and three pipettors. The goal of the practice is to replicate the formation and dissolution of copper hydroxide scale formed in pipes. Determine the solubility constant of the scale and the amount of acid and ammonia that would be needed to dissolve the hydroxide formed.
