7 Independent Reading The History of Can Making The History of Can Making Questions to follow Questions to follow

8 Aluminum vs. Tin

9 Aluminum Aluminum –What are some qualities of aluminum? Tin Tin –What are some qualities of tin?

10 Aluminum vs. Tin Aluminum Aluminum –Not magnetic –Bottom does not have rim –Brushed, polished appearance –Body is shiny, silver, and smooth –No seams on body Tin Tin –Magnetic –Bottom has rim –Shiny, silver appearance –Body has rings or ribbing –Always has seam on body

11 Aluminum vs. Tin Aluminum –Label usually sprayed on –Lighter in weight –Curbside pickup –Transfer station drop off Tin –Label is usually paper, glued on –Heavier in weight –Curbside pickup –Transfer station drop off
