The SC/SS 115 Ethnobotany class visited the FSM Coconut Development Authority processing plant on 29 April 2014.

Kosrae: Nahnek. Although lighter than elahk, elahk was preferred due to greater wood strength.
Pohnpei: Sadak. Used for canoe hulls.

Mathematical models exploration in lab 14

Laboratory 14 is effectively a practical laboratory where the students are given a somewhat ill-defined system and asked to explore that system, determine whether a mathematical model underlays the system, and if so, what is the equation for that system. Tagging onto a science video on flight and Bernoulli's law from last week, the class explored the launch velocity versus distance for Frisbees and flying rings. I was not clear at the start that the throwing angle should be zero, parallel to the ground, to remove the effects of a parabolic trajectory. The goal is to isolate the effect of the Bernoulli principle and not introduce the quadratic relationship of velocity to distance for an object thrown at an angle theta to the ground.

Throwers were lined up to throw at the radar gun holder. Johnson, Bertha, Terrance, Ryan, Serlyn.

Review for final in ethnobotany

The bulldozing of the ethnogarden led to shifting the final examination from the plants of the garden to the plants of the campus. This generated a new plant list. The class walked the campus from east to west, skipping the introduced ornamental plants. Fortunately my years of scattering plants around campus, and the planting of plants by others, have made possible the shift from a specific garden to using the whole campus as a garden.

Cultural ceremony in ethnobotany

Ethnobotany, being a Tuesday-Thursday 3:30 class, is always the last class in the last period on the last day before spring break. Attendance is usually low for the class. This term the extremely late date for Easter allowed the kava cultural ceremony to land on this day. With no class the next day, I did not have to be concerned that some students might linger after the ceremony. The field trip also solved the attendance issue. Twenty-five of twenty-six students were in attendance.

The class visited Nahnmadeu en Lehnpwel, Simion Nicholas, of Pehleng, Kitti, Pohnpei.
