# Huth, John

John Huth developed this activity for his SPU 26: Primitive Navigation class. The purpose of this assignment is to establish a baseline for their navigational skills. Students navigate Harvard campus to hold a course and estimate a traveled distance to see how successful they will be without any special training.

# Primitive Navigation - Coordinate System

Students go to the Harvard Chapel and establish a coordinate system of 'easting' and 'northing' using simply their bodies, their environments, and a notepad.

Using their knowledge of the use of a compass, triangulation, and uncertainties, students set off to walk to the bridge at the end of JFK Street in Harvard.

This activity was made by John Huth for his Primitive Navigation class, so his students will have practical experience working with primitive navigation tools through this experiment. This activity will help students understand navigational stars.

# Primitive Navigation - Small Angle Approximation

This is an in-section activity created by John Huth for his Primitive Navigation course where students walk small distances and use their analysis to learn small angle approximation, statistics, and prepares them for future assignments.

# Primitive Navigation - Sun Altitude

With the knowledge of the motion of the sun, the ability to find solar declination online, and how time can be used to find longitude from previous lectures in class, students must make a device to measure the altitude of the sun using a straw, protractor, and string weighted down to make horizontal.

In order to take a sighting, they move the protractor, looking at the shadow of the straw taped along the edge of the protractor. When the sun's rays are shining directly through the straw, the size of the shadow of the wall of the straw is...
