This term the ethnobotany class used Metroxylon amicarum, the local ivory nut palm frond, for thatching. The oahs costs more that Nypa fruticans but is what Pohnpeians actually use for thatch. Pohnpeians do not thatch with the Nypa palm.

Laboratory 042 followed the constructivist variation piloted spring 2011. I ran the set-up in the same manner in which I set-up last spring and last summer. I first asked the students to predict the result prior to any marble collisions. Then I released one marble on a shallow ramp. The marble rolled down and collided with a line of five marbles of roughly equivalent mass. I repeat this with two, three, four, five, and even six inbound marbles. For the latter cases I shift the focus to the "break-away group" retaining the inbound number as the released marbles also tend to continue on post-impact and eventually off the ramp. I then demonstrated that "speed in" is equal to "speed out." How does the penultimate marble "know" whether it should stay or go? How does the penultimate marble in the line "keep count" of the number of inbound marbles? Once the students have their minds wrapped around the mystery of the marbles, I ask them to form...

On 23 October the Ethnobotany class returned to the ethnobotanical weed patch worked on cleaning up the garden. Delphina cuts excess Hibiscus tiliaceus. Shalein hand-pulls weeds in another area of the garden. Risenta and Nadya look over the list of Latin names for the plants in the garden. Reliann amidst the Senna alata. Lecturing from the middle of the garden. The outdoors is a better location for class than indoors. Rose Ann examines a leaf while Shalein looks on. Headed through the tall grass, Delphina looks up at leaves on a tree. Deep in the underbrush with Shalein and Ashley, the shade tolerant invasive Clerodendrum quadriloculare on the left. Ivenglynn behind palmate Manihot esculenta. Clidemia hirta, an aggressive invasive. At trail's end Nadya far left, Risenta, Masumy, Emylou, Gray, Jane Rose, Julane on the right.

TJ and Rose Ann on the walk across campus, Rose Ann bringing the donuts. Stravinsky pounds the boards together while Jeff times ten seconds. TJ is holding the GPS. He has just returned from measuring the distance. Ryan tries his hand, or hands, at clapping the boards to produce the echoes. Clapping in synch with the echo allows the rest of the class to count the number of claps in ten seconds (hence the work Jeff is doing), and from that derive the speed of sound. Trishia tries clapping the boards. Left to right is Joana, Emily, Gunwick, Judy, Trishia, and Jo.
