Chemistry is the science of materials, their properties, and how they react with each other. All materials are made of atoms. Why do some atoms combine with each other while other atoms do not? Because atoms just want to be happy! Of course, atoms don’t really have feelings. But they do have observable behaviors. And atoms tend to be more stable, or “happy,” when they have certain numbers of electrons whizzing around their cores. Where do they find extra electrons if they need more to be happy? From other atoms that have too many electrons, of course! When atoms share or exchange electrons to be happy, they stick together. Happy atoms form molecules! With this revolutionary approach to teaching chemistry, you can make your own happy atoms! This physical and digital system lets you discover the world of molecules in an intuitive, hands-on way. Using a set of 50 atom models representing 16 different elements, you can assemble your own molecular models. Many people think of chemistry as complicated and hard to grasp. New technology now enables us to take this innovative approach to teaching chemistry, making it more tangible and instinctive than ever before.Details:Digital and physical chemistry set52 piecesCreates 50 unique atomsIncludes 226 activitiesIncludes 16 page manualApp requires tablet or smartphone running iOS 8 or Android 4.4 or laterFor ages 10 through 17
