Mass of U.S. Pennies

Long Description: 

Students will represent data through histograms for analysis and interpretation. Students will use an electronic balance to determine the mass of many, many U.S. pennies (a one-cent coin) of varying ages. The metallic composition of the penny has changed over the years. Different compositions can have significantly different masses. A sufficiently random selection of hundreds of pennies should allow the students to discover the years in which the composition changed.

Students create and interpret a histogram of penny masses.
