Today in class we used a virtual comparison microscope program to compare the firing pin impressions of firearms on shell casings.

Students were to complete test 1 & 2 in the cartridge casing activities. (Scroll all the way to the bottom. Read the directions on the site to use the program.)
Students needed to receive a 75% or better on both tests to get the points for the assignment.
