This exercise develops team work in data collection, requires the production of a simple spreadsheet, and the exporting of the data from that into one or…

Describes a computer program based upon field observations of littoral zonation modified by a small stream. The program employs user-defined color graphic characters to display simulated ecological maps representing the patterning of organisms in response to local values of niche limiting factors.

Describes an experimental setup using a microcomputer for demonstrating the circadian movement of petioles. Discusses experiments that were performed using this apparatus and factors that relate to these plant movements. Includes graphs that have been obtained. (CW)

Because advanced students had difficulty in interpreting cleavage patterns obtained by gel electrophoresis related to rapid sequencing techniques for DNA and RNA, several formats were developed to aid in understanding this topic. Formats included print, print plus scrambled print, interactive computer-based instruction, and high-resolution…
