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...

The laboratory on cloud types have shifted from Luke Howardian cloud drawings to Slides presentations with Snapseed labeling. This new format has lost the return-to-childhood atmosphere that coloring clouds with crayons brought. The use of Snapseed and Slides, however, builds nicely on the redesigned rock identification laboratory, reinforcing the skill set first developed in that laboratory. Elvanie working on her phone The videos run to just over an hour. In the morning session I neglected to show the cloud types presentation , but then the videos covered this same terrain fairly well.  Just-Wesley, Lousaintra, Meramy, Brithney At 11:00 YouTube would not load. Down detectors suggested server issues with YouTube. No other sites used for this lab appeared to be impacted. The videos were dropped and just the two presentations were done. This worked better than expected. If done again this way, with only the presentations being presented, then the cloud types sl...

With reasonably attendance this term, an attempt was made to run a two sample t-test for a difference in aircraft flight distances by gender. With roll call and working assignment 11.1, the class turned to folding paper aircraft 11.2 by 9:14.  Maryam working on her paper aircraft. Arthisha and Elaine making paper aircraft. Spreadsheet The throwing and measuring was done with the males throwing first, one by one, then then females throwing, also one-by-one. Measurements were done as planes landed. This was slower than having all planes thrown at one, but not significantly slower. Measurements wrapped up by 9:26. The data was entered into blank sheet built on the fly. The statistics were added once the class was back inside. As is the current practice, the spreadsheet was a single tab, which helps the Smartboard. As seen above, a 95% confidence interval was also calculated. A histogram was done in Statisty.app.  The sample sizes are far from e...

For a second term the rock characterization and identification laboratory was done as a Google Slides submission.  This rock proved a suboptimal choice as there were two potential identifications. The camera on the Tripltek, which was used because of superior connectivity to the Smartboard, does not produce a high quality image. A slides presentation outlined the process for the laboratory. Elvanie runs a photo analysis on a rock. Students worked with five rocks. Leann also working on photo analysis. With exceptions, most Android phones can run Google Lens or the Gemini app. Newer iPhones can use Apple intelligence.  Another Android option yet to be explored is Rock Identifier: Stone ID. RockD has proven overly aggressive in pushing the premier version and was not recommended this term. Another fall back for rock identification is ChatGPT.  Vandasia and Tayshaun working on their rocks. Finolla and La...
