** My second grader (who is an advanced learner) has been glued to this app!! ** Marcy Boudreaux-Johnson, PhD, educator ** Unconventional science app.... worth a look. ** Children's Technology Review Exchange ** The app is a fun way to explore scientific concepts. I'm loving the new features in the latest update. ** Angela Moorad, founder of OMazing Kids, LLC ** Educational game you'll want to your children to play... intuitively understood ** app-liv.jp ** Amazing app for kids! Highly recommend. The characters are very cute. ^_^ ** A user from Finland *** No in-app purchases. No ads *** Science for those who hate science! This is the story about a curious robot that wants to be amused. In this STEM game you can take him to mysterious planets and show him some marvellous things. You’ll have fun abducting different creatures, and learn some science while you’re at it. The app includes: -- mini game that explains what sound is -- mini game that explains what temperature is -- mini game that shows how small atoms and molecules are; what is millimeter, micrometer and nanometer -- mini game that explains what gravity is and how planets form -- mini game that shows what things are made of -- short story with poems * * * There's a robot who lives in a far away constellation That robot looks like a dog, but not a Dalmatian. He knows everything about water, steam and ice How to drive a flying saucer And how to find nanomice. * * * Explanations are included. Just tap the little robot when his nose is flashing and read all about you see. * * * Let your screen time become educational time! * * * Introducing CLASSROOM MODE! * * * With this new version of "Hi Nano" teachers can use the app to explain certain scientific concepts to their students. They say a picture is worth a 1000 words. We believe a mini-game is worth 2000 words. Just give an iPad to a child to play, and he or she will never forget how particles behave at different temperatures, what sound is, how small particles are, etc. Just tap the teacher icon in the main menu and pick any planet on the map. Now you can access all the colourful interactive learning scenes without having to play the whole game from start to end. * * * "If, in some cataclysm, all of scientific knowledge were to be destroyed, and only one sentence passed on to the next generations of creatures, what statement would contain the most information in the fewest words? I believe it is the fact that all things are made of atoms — little particles that move around in perpetual motion. In that one sentence, you will see, there is an enormous amount of information about the world…" Richard Feynman
