Your students will learn how to determine the density of several types of glass, including automobile, window, Pyrex, and leaded crystal by immersing each piece in water and determining the volume and mass of the displaced water. They will also use various liquids with known refractive indices to estimate the refractive index of the piece of glass they are analyzing. In addition, students will discover how to determine the chronological order of breaks in a single pane of glass produced by multiple bullet holes and the direction of a projectile's force by analyzing the conchoidal lines. The activity includes enough materials for eight lab groups, a teacher's guide, and student copymaster.
