NSDL teaching resources related to “split”

In this classroom activity, learners construct a wobbly model of a crystal array to investigate the attractive interaction between neighboring atoms in a solid. By using this less traditional model, students explore chemical bonds as analogous to a stretched or compressed spring. Gently shaking the model shows how stored energy can be communicated to the next layer of atoms. Vigorous shaking causes the model to break apart, representing the breaking of chemical bonds.
