Purchase or make the transit rods—see attached
directions. If using purchased rods that do not
have a sighting hole, drill a hole (1/2 “ diameter)
through the center of each pole at the zero mark.
It is not necessary, but makes sighting the horizon
easier.
• Copy the Beach Profiling Data worksheet—one
per group.
• Copy the Graphing the Profile Sample handout—
one per student.
• Select a beach area to profile. It should be a
beach that shows change with the seasons or has
shown change historically. Ideally, students
should be able to compare their profile to other
profiles or historic photographs of the same
beach in different seasons.
