Topographic survey.
This word seems inappropriate to children of middle school, but try with us. First of all the tools needed: one to measure distances, one for measuring angles, some sticks and of course paper and pen.
Measurement of the distance: we built a "measure tape" made in practice by a roller on which we have wrapped a long string marked every 5 meters.
Measurement of the angles: our "angles measurer" is a graduated disc able to rotate freely on a base of wood with a peg of reference on the disk and one on the base to make alignments.
Reference rods: some 2 meters tall reeds will fit our purpose.
