Atom Kits

These versatile atom kits provide for hand-on exploration of inorganic compounds LetÕs face it Ð there is simply no substitute for the understanding a student will achieve by actually building molecular compounds themselves. These fun and easy to use kits allow students to experiment with different bonding types while learning fundamental chemical concepts. We have designed these kits carefully so that each "atom" (colored ball) can only form the type of bonds that are possible in nature. The unique design of the different types of bond representations (i.e. round holes for single bonds and square holes for double bonds) demonstrates restricted rotation. Even complete chemical reactions can be reproduced! Molecular construction sets come in four versions, each one consisting of more ÒatomsÓ and thus allowing more complex and sophisticated reconstructions. All demonstrate the fundamental concepts of atomic bonding such as the physical and chemical significance of bond lengths and Van der WaalÕs radii and fores. Moreover the student learns the value of constructional models as an aid to study. The Research Construction Kit is sophisticated enough to be used for true research applications such as the pre-evaluation of the risk of stearic hindrance in a specific reaction.
