6. Abstract

This archive proposal is based on the opportunity afforded by the new six-pointing
mosaic of M 51, taken as part of the Hubble Heritage project. The goal is to produce
a set of educational activities for non-science majors taking introductory astronomy
courses. In the first phase, the subject of this archive proposal, surface
photometry and aperture photometry will be carried out for selected regions that are
typical of (a) the nucleus, (b) the bulge, (c) an inner spiral arm, (d) an inter-arm
region, (e) an outer spiral arm, (f) the nucleus of the companion, (g) an off-
nuclear region in the companion, (h) the edge of the disk, (i) the tidal tail
connecting the two galaxies, and (j) a region displaced from both galaxies. A fully
registered true-color image will also be created. In the second phase, the subject
of a companion E/PO proposal to be submitted later this year, instructional modules
will be created based on the ten sample regions, where each can be viewed and
measured by students using Java web tools. The goals of the activities will be to
use research-level astronomical data to teach about (a) the range of stellar colors,
(b) stellar luminosity, (c) different stellar populations, (d) effects of dust, (e)
active nuclei, (f) the significance of angular resolution, and (g) the concept of
surface brightness. The potential audience for these new materials is the 250, 000
students who take introductory astronomy courses each year at colleges across the
country.
