Floral morphology

Gardenia taitensis is actually a dicot despite the six petals Floral diagram after the floral video playlist Seven petal Gardenia taitensis Hymenocallis littoralis Stamen: filament and anther A scorching hot sunny day Spathoglottis micronesiaca  Elmerlynn, Sharla, Cassandra Elmerlynn, Berkarihna, Sharla, Reenomilyn, Cassandra examine the Spathoglottis micronesiaca  This was the initial team that followed me into the swamp no questions asked. The crowd burgeoned only as I took the orchid role

Colors of Light

Image
Monday began with an attempt to outline the sequence followed by the Limits of Light video that is used to introduce this week that focusing on the spectrum of light and the colors of light. This diagram was perhaps less illuminating than the one from last spring term . I suspect that the spring term diagram with additional notes on the video starting in yellow might be more logical and make more visual sense. On Wednesday I had the students view the visible spectrum using CD spectrometers. Alathea and Renae Darian and Aryolynn Using input from the students listed the colors seen in the spectrum and discussed the origin of the seven color rainbow.  Thursday opened with the physics of color vision and digitally produced color. Desmos was used to explore color as was done spring 2023 using the new color command. A Desmos graph can be used to illustrate the relationship between the color and the hue angle. Another Desmos f...

Material culture

Joana Amyda shared a carved wooden turtle carved by Kapingan carvers called a digee. Sharla Edwin and a breadfruit corer Elmerlynn Elias displayed a mwarmwar. Sehr en wai.  Cassandra Hagiltaw Coconut fiber rope. I opted to permit students to pre-submit images for large objects that could not be brought to class, but his opened the door to images of smaller or other objects. This has me rethinking this whole presentation. Students in the past would bring a coconut basket or other item they had made. This term the students were more hard pressed than ever to bring something that is actually in active use in their daily life. I could have been more clear about this, but that might not have helped. There is so much loss of material culture. Jessa Elsy Holliday: Koahl. Hibiscus tree bark skirt. At one time a student might have at least put the koahl on over their western clothes. In this case Jessa does not have a koahl that wi...

Thatching

Image
Thatching opened with the question "What are the two styles of Pohnpeian thatch?" Setting aside a student from Chuuk lagoon, two from Kapinga, one from Lamotrek, one with roots in Chuuk, and two with roots in the Mortlocks, the other 16 students were Pohnpeian. After polling around and not getting an answer, one student from Paies answered with hesitation and uncertainty in her quiet voice. She was right, and by her expression she had not been sure that was the answer. In years past the students taught me these two styles. Now the knowledge is slipping away. Sharla, Mesenda, Elmerlynn, Joanalynn, Mary May displaying their completed dokoahs en ruk thatch panel. In the past the spelling for weaving thatch has been communicated to me as being doakoahs. The dictionary indicates that the spelling is dokoahs. As the orthography is phonetic and sounds are consistent with spellings, the difference will likely be a pronunciation difference. English is not phonetic and hold...

Waves

Image
Monday was an observation day and thus I wanted to see if I could run the RipStik wave introduction in A101. In the morning I tested the RipStik on a sheet of poster pad in A101. No mark. The floor is too smooth.  The shiny looking wheels are because... that is a new board But the sidewalk outside A101 left a strong track. So I used the sidewalk, which is rough enough to cause a difficult start. Then I brought the three sheet poster pad inside and put it up on the board which improved visibility. I thought I had seen the timer record 1.71 seconds, but post hoc the timer was blank and was in countdown mode. At the point I realized that I did not have a reliable time I already knew I had 3.5 wavelengths on the paper. I ran with 2.1 seconds for the full transversal. This produced a period of 0.6 seconds and a frequency of 1.67 Hertz. The wavelength came in at 70 cm. The track was not straight but was close enough.  The wave speed worked out to ...
