Education Galaxy has gamified education. Students work on specific learning standards and when they answer incorrectly they are provided direct feedback. When they answer correctly and master a standard they are allowed to play a game with their own personal avatar and rocket.

PhET Interactive Simulations, a project at the University of Colorado Boulder, is a non-profit open educational resource project that creates and hosts explorable explanations. Students are allowed to change variables in a safe environment to see what happens. This includes skateboarding, circuits, states of matter and pretty much everything else under the science umbrella. There are activities and questions at different levels for each simulation.
