The weather in the morning was rainy and wet which made the decision to use the indoor version of the laboratory. This was way too many graduated cyclinders. The student groups only used one graduated cylinder and two 1000 ml beakers. The gear collection was somewhat eclectic. And I forgot the PVC pipe which I use to demonstrate resonant wavelengths. I also failed to remember that a third slinky spring is kept in the sound box just for this laboratory. Austin and Tommylee  Use of a beaker works best. The graduated cylinder cab start off filled with water, that water can be poured off into the two beakers.  Bennie and Leann Lanve and LizzyAnn The 1024 Hz tuning fork resonance is hard to pick up aurally. Leann found a way be able to listen more closely by placing the cylinder on the floor. Lashanna joined Bennie and Leann Jay-brion, Elvanie, and Brithney Meramy, Ariana, an...

The session today was slated to end at 16:40 to allow for course evaluations to be conducted. With rain bands rolling off the ridgeline in waves, this would normally cause the indoor video playlist option to be invoked. I really didn't want to preface the course evaluation with a video playlist, despite the weather issues. A floral handout was cobbled together ahead of class and 25 copies were printed for the students, a rare instance of printing anything.  At 3:30 a rain band hit campus. I opted to wait out the rain band in order to start at the Hibiscus rosa-sinensis across the road. When the rain band had cleared out to the west sufficiently, the class crossed the road. Another rain band was rolling over the ridge as I wrapped up coverage of the four whorls and their constituent parts. From there the class crossed back to view  Gardenia taitensis flowers. The class was strung out under the eaves of the building, most could not see the floral dissecti...

The rain and shortened period on Monday provided an opportunity to start from the RipStik wave on Wednesday. The RipStik wave was put up on the board. The colored magnets were too weak to hold the paper up. Gear included the rope, spring, meter stick, tape measure, and a timer.  The golf ball was brought along but not used. The rope was used to re-introduce, wavelength, period, and frequency.  Amplitude was unintentionally omitted due to oversight.  The spring was then used to demonstrate both transverse versus longitudinal (compression) waves with definitions echoed onto the whiteboard. The spring provides a visual connector from a transverse rope wave to a compressional sound wave. The sciencemusic site had a good sound simulation that ran on the Smartboard. This provided a nice bridge from the dance of the "moles-cules" of the unit on heat to the sine wave that sciencemusic can also produce in another simulat...

Pouring rain and rain driven wind gusts were problematic this term. Prior to class there was a brief splash of sunshine. Dark spots are drips from an earlier rain storm. The ends of the four sheet poster pad set were edged with duck tape. The duck tape did not lead to sliding out or instability when crossed on the RipStik. There was no dry patch on which to write the definitions. The period was set to be compressed due to that last ten minutes being scheduled for course evaluations. Despite the weather and conditions, the decision was made to remain on the sidewalk.  In addition to drips and drops, rain was blowing in onto the paper. The roughness of the sidewalk was also problematic. With a full 50 minute period available, returning to the classroom is recommended given the surface condition of the sidewalk. The definitions were run through in just over 30 minutes.  A Desmos file of the RipStik wave was ...

Rain bands with rain driven wind gusts slammed Pohnpei all day today. In town wind took down at least one shack. Out on the road to Sekere a banana blocked the Kolonia bound lane. Himawari satellite shots showed that the heaviest precipitation was moving west to east, but on the ground the rain was moving from east to west. I never did sort this discrepancy out. The Vitz proved more capable of handling long loads than the Demio.  The rau always extends to the front seat, but in the Demio the hatchback has had to left open on occasion as the rau are moved from maintenance to the gym on campus.  The oahs and rau arrived just before two, and I was on the leeward side of the gym by 14:20. I went to collect an Ixora casei stem, still thinking the class might yet engage in thatching.  By 14:55 I was four or five fronds into doakoahs en Ruk. I set that aside and went to work on doakoahs en Pohnpei. I was well along (further than at...

The class tested the hypothesis that there is a difference in hula hooping by gender as measured by the number of rotations. Spreadsheet With only four males present the sample size was kept at four for both genders. "Equal sample sizes are not strictly required for an independent samples t-test, but they are ideal because they increase statistical power and make the test more robust to violations of the equal variances assumption. When sample sizes are equal, the t-test's validity is less threatened by factors like differences in variance, and the results are more reliable." - Gemini  The men took the lead and went first. Omar would power through to 160 rotations. Aikman's first time to hoop Grace took the lead for the females Emars hooping Anastasia wrapped up the hooping for the females. The result was no gender difference in hooping skills as measured by the number of rotations. While this exe...
