I am interested in calculating the distance from the earth to the sun. In the past, I heard of a way to do this by measuring the sun's shadow at various times and at two different locations. Is this true? I do not know all the details, so if you can supply the details or refer me to a reference in which I can have my class calculate the distance, I would appreciate it. The class that I teach is pre-calculus, so the students know trigonometry.

A good and widely available reference is MATHEMATICAL METHODS IN SCIENCE by George Polya. The publisher is The Mathematical Association of America and this is Volume 26. in a long series of books designed to provide material for secondary students on topics not usually seen in high school syllabi. Section 2 on "Astronomical Measurements".
