Food presentations in ethnobotany  Dipchig, boiled ground banana from Ulithi.  Dipchig is comprised of boiled ground bananas. Variations on this are found across Micronesia. On Pohnpei this is known as uht idihd, in Kosrae ap. Banana in Ulithian is yuch, in Woleaian wiish, in Pohnpeian uht, and in Kosraean usr. One reason students bring in foods is that although the recipe sounds the same, the result is not. Dipchig is a lighter, less dense, almost cake like dish. Uht idihd and ap are denser. A Mortlockese variant of uht idihd brought in today was even smoother and denser than Kosraean ap and typical Pohnpeian uht idihd.   Kimberly of Kosrae, Beverly of Woleai, and Maryam of Ulithi.  Mortlockese presentation of Pohnpeian uht idihd. This dish was dressed with coconut milk after slicing as if frosting the uht idihd. The texture was smooth, a gel like consistency with a glassy shine to the cut surfaces of...

As an introduction to an exponential system, the cooling curve laboratory consistently delivers. Simple but effective. And the mathematics makes sense: the decay is asymptomatic to room temperature.  The use of open top containers introduces convective loss which apparently alters a pure exponential decay, but the uncertainties inherent in reading the school thermometers exceed the convective errors. Left board with a predicted mathematical model. Right board with the equation. The equation was not revealed until after the cooling curve was generated in the 8:00 section, but then the equation was left on the board after the 8:00 section.  A question arose on Friday as to how many mathematical models are there. The answer depends on how one counts models. There is an infinite series of polynomials of degree n. Broader families can be discerned. Some of the broader families can be seen above, noting that the square root...

Started with two students at 3:30 showing them the posters on the walls.  Van arrived and I opted to walk down towards the Garcinia xanthochymus, which was laden with fruit. The Eugenia uniflora was gone due to a fence. The Averrhoa bilimbi had no fruit.  We returned to the tables area for the CHEEF benefits presentation . Japanese agriculture research center well lit by the afternoon sun on a blue sky day To my surprise, the class actually wrapped a little early at 16:30.

To demonstrate that relative frequency is probability and to show that sample values can only lead to conclusions about what the population values are not, not what they are, a mix of two colors of marbles were used.  Spring 2025 35 blue and 15 green marbles were put into a cloth bag. 14 students were present at the time of the draw, each blindly drew a single marble. The result was 11 blue and 3 three green for a 79% and 21% relative frequency. The actual relative frequencies were 70% and 30%.  Fall 2024 a mix of 40 blue and 12 orange marbles was used, 77% and 23%. The draw by 21 students was 13 blue and 8 orange, 62% and 38%.   Fall 2025 30 blue, 20 orange, and ten white marbles were placed into a cloth bag. 18 students each selected a single marble.  Some of the questions posed ahead of the marble tally included: What percentage of the marbles in the bag are blue, white, and orange? Can I know the number of marbles in the bag from the ...

Force of friction ran on a cold open, one-by-one mentoring start. A single student arrived by 8:00, instruction was one-on-one. No opening lecture or explanation. As students trickled in, each was either started on measurements or added as a partner to an existing solo experimenter. Initially gathered data during the demonstration phase was echoed to the white board. Austin and Yonard measure the effect of weight on the force of friction. Vandasia and Tayshaun measure the effect of weight on the force of friction. LizxyAnn and Bennie test the effect of grit size the force of friction. Tommylee worked solo and found that in the force range where the green and blue spring scales overlap they do not produce the same result for a given load. To think to check for this possibility is deeply insightful. He understood the implicit assumption that the scales were both accurate, questioned that, and found that they were not. Absolutely...
