Crystals: What Are They and What Holds Them Together

Students are introduced to the characteristics of crystals and what keeps them together. Using the Periodic Table, they examine the various elements and develop a model of an atom. In groups, they place sugar and salt in petri dishes and record their observations of how the crystals change on a daily basis. To end the lesson plan, they answer questions based on the growth of their crystals and compare them with others.
