Dave’s class has just finished an introductory reading on chemical reactions involving acidic rain and the copper found on some city buildings or - in the case discussed - the Statue of Liberty. The class has just received directions for a lab which will examine the reactions of an acid (vinegar) on pre and post-1982 pennies. (As you may know the compositional percentage of copper is vastly different in each vintage.)
In a small way, this highlights the goals of all our science classes, which is to provide important scientific factual information, key intellectual concepts, as well as the daily life applications of both.

PS ... It is almost 60 degrees, the last of the snow is melting and we will have a stretch of unseasonably warm weather coming up.
