Scientific paper
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.
