A SkyServer Advanced project, intended for honors high school and college students. Students examine the magnitudes and redshifts of six sample galaxies and create a simple Hubble Diagram showing the expansion of the universe. Then they consider some of the complications involved in making a Hubble Diagram, and look at clusters of galaxies to account for galaxy differences.
A SkyServer project for 3rd to 8th grade students. Students make pencil drawings of galaxies as seen by the Sloan Digital Sky Survey. They compare their drawings to other students' drawings of the same objects, looking for similarities and differences.
A SkyServer Basic project, intended for middle school and high students. Students look at the spectra of 14 stars and classify them into groups based on common features. They then learn about the OBAFGKM classifcation system that astronomers use, and reclassify the same 14 stars in OBAFGKM categories. Finally, they learn about some stars whose spectra do not fit neatly into the classification scheme, including carbon stars.
