Subject: Re: Measurement

I started by doing a search on the Math Forum site using:

http://mathforum.org/grepform.html

and I found this Ask Dr. Math response:

http://mathforum.org/dr.math/problems/sen7.16.97.html

and if you look at #6 it mentions:

 6. Make and use a clinometer (sextant) to indirectly measure five lengths.
Do this project only after having studied similar triangles.
Reference: "The Mathematics Teacher", Feb. '76, p. 135.

I don't know if you would have access to this periodical but it sounds like a
great source for what you want.

Then I found this lesson plan which looked more introductory than what you
had in mind:

http://mathforum.org/paths/measurement/tall.html

Then I went to http://ask.com  and just searched for "clinometer" and found
this site:

Clinometer to measure the height of Trees - Elanora Heights Primary School
http://www.zip.com.au/~elanora/tclinom.html

I hope that helps.
