Abstract
A current trend in chemical laboratory instruction is the use of cooperative laboratory projects to promote active student learning. This paper describes a project-based laboratory experiment in which students determine the composition of an unknown metal knob that was ingested and recovered from a large puppy. Students utilize two different methods, for example density measurements and spectroscopic analysis via AA/AE or ICP, to elucidate the major constituents of the metal object. This laboratory exercise would be appropriate for an analytical chemistry or instrumental analysis course.
