Presentations on gymnosperms, angiosperms, spices, and timber trees.

Spencer Francisco on gymnosperms Leaf morphology for gymnosperms Rico Joab Best penmanship seen on a poster, Benhart the calligrapher Monocot and dicot differentiation with Jenny Gabriel
Jenny Gabriel Carie-Ann on cinnamon Sother Junior presenting, Merlina on the right Arlen presents Nutmeg facts - delivered by a student who chose to face the board for the whole presentation Leona Saimon on Araucaria timber Charlotte Eperiam speaks on Eucalyptus deglupta as a timber product Hanae Shimuzu presented shiso Carlinda Joab on Kauri pine products Lerina Nena with a very detailed angiosperm life cycle diagram

Latitude and longitude

This term I returned to the area to the southeast of the gym. Fall 2013 a Spensonian deluge flooded out the hide location atop the trail head I had chosen. This term I opted for a weather friendlier site. The first group found me at 12:18. This term no other group was near the first group, so I remained at the hide when they left, a first. This worked better than I expected - the second group did not arrive until 12:48, with the third group close on their heels.

Donbert, Jessica, Nikita in the second group
Amyleen Tom, and Johnnyboyd Joseph were the third group
No images from the 072 laboratory which was done using the linear regression to obtain a minutes to meters conversion. This worked well. Off of both the first palm at N 6° 54.567, E 158° 09.597 and second palm at N 6° 54.570, E 158° 09.597 distances of 180 meters were obtained into the college intersection to the East. Work in the lab suggested that shifting from 30 meters to 30.48 meters does reduce the error, so maybe 99 fe…

Thermal conductivity and mathematical models

An attempt to build on last term's note, "I fiddled and tweaked my way to the initial logistic expression by using a computer in the possession of Brinando and Megan. They watched as I fumbled and fought my forward to a design that would behave in a way similar to their data. I explained what I was doing and why, including referring to the (x - h) portion of the graph. I gather one or both had MS 101 Algebra and Trigonometry, so they were not necessarily completely lost in my ramblings. I thought that interchange was valuable, that exercise was valuable. They were able to see their instructor struggle with a mathematical model, not have it quite right at first, and then iterate his way to a reasonable solution," did not go as well as hoped in the 8:00 lab.


I did not use a lap top as I did in the fall. Note two that all but one group saw an immediate and rapid linear rise in temperature until the peak temperature was reached. Only one group had that characteristi…

Pwunso Gymnosperm and Spice Plants

Image
The ethnobotany class visited the Pwunso botanic garden on 18 February to view gymnosperms and economically valuable plants. The Clove trees were producing heavily. This suggests that cloves, like cycad cones, are a spring term production. That cloves have appeared twice but not previously may simply be a factor of the age of the trees.

 The class heads over to the Cook island pine trees.
 The cycad sported cones.
 Immature coffee cherries - seems too early for the fall crop, maybe an out of season berry.

Healing plant presentations

SC/SS 115 Ethnobotany healing plants of Micronesia presentations
Rico covered the use of young breadfruit leaves to staunch bleeding from a cut.
Nayleen Doses described the use of four, paired young guava leaves to stop diarrhea.
Charlotte Eperiam noted that the young leaves of ketiou, Ixora casei, can be used to staunch bleeding. I do not recall that use of ketiou having been presented before.
Jenny Gabriel spoke about the use of black, ripe topwuk (Premna obtusifolia) fruit to stop the spread of chickenpox on the skin and to relieve itching.
Francisco Hadley covered the use of soursop tea (sei) to prevent the development of cancer.

Carlinda Joab noted that sakau plant leaves (Piper methysticum) can be used to staunch bleeding.
Lilly-Jane John spoke of the use of "fedin" to staunch bleeding. One would come to the conclusion that there is an awful lot of bleeding around here.

Jamie Barnabas spoke of the use of Piper betel leaves to staunch bleeding. I noted to the…

Pulleys

Image
Photos of the pulley laboratory both by the instructor and by Rilensha. The 5.2 version of the laboratory is as well structured as the laboratory probably can be. No major changes are required in the laboratory.

 I could not remember the set-up for this three string pulley. Baffled me in the early morning.  Johnnyboyd records data.  Donbert holds the spring scale.  Johnyboyd and Donbert.
 Calculating the trend line with a calculator.
 Amyleen and Shra Ringlen
The six load line pulley was twisted and generated a low efficiency. Jessica Gilmete adjusts the load.
