In the battle of mass?weight I choose to take up arms with Cheri.  In my
ninth grade classes I consistently hound the point that "balances" are
used to determine mass and spring scales to determine weight.  In this
course we are dealing with properties of materials, mass is a property
that remainsconstant for a given material regardless of its location.
Unfortunately, when these same student s get to Chemistry as Juniors,
they consistently weigh things to find their mass.  However, when I see
them again senior year in Physics, they quickly return to the
terminology used in ninth grade, especially as we discuss weight as a
force.
