With this revolutionary approach to teaching chemistry, you can make your own happy atoms! This physical and digital kit lets you discover the world of molecules. Using a set of 50 atom models representing 16 different elements, you can assemble your own molecular models. The atoms stick together easily with magnets: metal tips on the ends of rubbery arms, which represent free electrons, snap onto magnetic bonding sites on the atom spheres, which represent empty spots for electrons in the atom’s outermost electron shell. Snap its picture and the included app uses state-of-the-art image recognition technology to identify the molecule. The app recognizes tens of thousands of molecules and presents detailed information about 150 of the most important molecules. You can track your progress with the app, collecting sets of molecules that you have built and explored. Requires a tablet or smartphone running iOS 8 (or later) or Android 4.4 (or later, with 1 GB RAM, dual-core processor, and built-in camera).
