Sun in Time
In order to get a feel for how astronomers might measure the altitude, or height above the horizon, of a star...or any object, students can build a simple sextant. This PDF file (you will need Acrobat to print this file) will give you, the teacher, some important background information on sextants. If you download this file (also a PDF file), you will have the student version of the experiment, which includes the data sheet and some post-lab questions. A good history of the astrolabe may be found by clicking here.
If you don't have the Adobe Acrobat PDF viewer, you can download it free, from http://www.adobe.com/prodindex/acrobat/readstep.html.
The Sun in Time, sponsored by the NASA IDEAS program, is a joint partnership between NASA, the von Braun Astronomical Society, and Huntsville area middle-schools.
