The document outlines how a teacher used an ELMO document camera to facilitate a jigsaw activity where students researched chromosomal abnormalities. The teacher demonstrated the ELMO components and setup. Students were then divided into groups and assigned a section to read about characteristics, examples, non-disjunction, or human disorders related to chromosomal abnormalities. The groups summarized their section on post-it notes which were then placed on a template under the ELMO camera to share with the class.
