Molecule Rush App for iOS
'The Molecule Rush app was created to be used alongside the Build a Molecule Model exhibit. It aims to make chemistry relatable by educating users how to build and arrange atoms to create molecules. Users recreate molecules. After successful completion, user can proceed to progressively more difficult levels. Molecule Rush is different from other apps currently on the market because it not only engages users but informs them as well.'
