ABSTRACT
This chapter discusses an activity of how high school students apply their knowledge of density to solve an unknown variable, such as thickness. Students leave this activity with a better understanding of density, the knowledge that density is a characteristic property of a given substance, and the ways in which density can be measured. Students are engaged in scientific inquiry in order to work together in developing a procedure and communicating their ideas to solve a problem. The key to doing this activity is teacher preparation. Students need to measure the mass of the shot to calculate density. By the end of this activity, students should be able to understand that volume is expressed both as milliliters and centimeters cubed, to know how to use an object's density to solve unknown variables, and to understand that the density of a given material does not change with the shape of the material.
