Making Cents of Density

Activity Overview

In this activity, students will measure the mass and volume of several collections of a coin type and enter the data into their handhelds and explore for patterns. Students will also make a plot of mass vs. volume and create a mathematical model that demonstrates the relationship between mass and volume.
