"What causes a balloon to stick to a sweater? How do microwaves heat coffee? How is electricity generated from a bar magnet?
The physical world poses a number of questions. The PhET Interactive Simulations project at the University of Colorado Boulder helps students discover the answers and go beyond, while improving their scientific literacy.
The PhET project, founded by Nobel Laureate Carl Wieman and funded by the National Science Foundation (NSF) and others, provides free, interactive, research-based simulations of physical phenomena for elementary through university students. NSF's Directorate for Education and Human Resources (EHR) provides primary support through its Transforming Undergraduate Education in Science, Technology, Engineering and Mathematics program (and its predecessor the Course, Curriculum and Laboratory Improvement Program) and the Discovery Research K-12 program."
That is from the National Science Foundation article on PhET Simulations provide Interactive Learning Tools.
The LTF Science Team is working with the PhET team to develop inquiry based lessons that go along with their simulations. These simulations are pretty amazing and can really help students understand physics - and very soon, mathematics.
More to come when these lessons are ready!!
