PhET simulations are freely downloadable interactive simulations. The simulations are available in various file formats such as html5, java and flash. These simulations provide an interactive environment which will enhance learning. Students can change various parameters in the simulation interface and see the effect of the changes they made. In Biology category simulations for various grade levels are available. Simulations cover variety of topics such as Colour Vision, Sound Waves, Gene expression, Natural selection, etc. Read more
