Perfect for at home, in class, or on the road, this app delivers all PhET HTML5 sims (over 75 sims) in one easy-to-use package. Developed by experts at the University of Colorado Boulder, PhET sims are used by millions of students every year. The PhET iPad app delivers these exclusive features: • Offline play: learn on the bus or at the park without a WiFi connection. • Multiple languages: app translate in many languages (great for bilingual learners). • Favorites: pick your favorite sims and create your own custom collection. • Automatic updates: get the latest HTML5 sims as soon as they are released. • Easy sorting: find the right sims for you. • Fullscreen: maximize your screen real estate for optimal sim exploration. PARENTS: Engage your child in science and math discovery. TEACHERS: Your favorite HTML5 sims at your fingertips, even without internet access. ADMINISTRATORS: Optimized for school use, so your teachers will be seamlessly up to date. STUDENTS: Tell your parents there’s an exciting app for learning science and math. Note: The app does not include PhET’s Java or Flash sims. In addition, although we are currently working on improving the accessibility of our sims, most of the sims included in this app do not include keyboard navigation or screen reader access. As accessible sims become available, they will be updated within the app. Proceeds from the app support the development of more HTML5 sims. On behalf of the PhET team and the students whose lives you have helped improve — Thank you!
