10.1 Fibobelly

Image
Fibobelly proceeded with less emphasis on Internet support for the golden ratio navel. Sites that espouse this are either disappearing or noting that this is an urban legend. Maryam measures Arthisha Spreadsheet   For the females, the golden ratio can be ruled out. For the males  the golden ratio is a possible population mean.

9.2 Paper aircraft confidence interval indoors

Image
This term rain bands were crossing campus which usually cancels the exercise where the students throw paper aircraft from the balcony. This would be the first term to try the new "physical science facility" across from room A101.   In that exercise the long term average flight distance is 560 cm. Arthisha throws her paper airplane  With no pre-existing population mean, three aircraft were thrown ahead of class with an average flight distance of 326 cm. This was put on the board ahead of class.  Zero cm was the front edge of the mat. Tiles are 60 cm square. Maryam viewing a video on how to make a paper aircraft, Lidy-Loreen makes her aircraft, Aliha in the background. This is the cell phone generation: they do not know how to make paper airplanes and rely on YouTube videos for instruction. Planes in the hallway. Measurements were done as planes were thrown. LanaSunshine throws her plane. Students ...

Arcminutes to meters

Image
With the satellite showing a band of heavy rain inbound from the east, a cold open was done without entering A101. In a scoop and go, the students present at 08:00 were taken west to the covered sidewalk between administration and the dining hall. This term the tape measure was used at both 8:00 and 11:00. The tape measure makes more concretely clear the measurement of meters on the ground.  This term the zero was shifted eat a few meters. The 53 meter mark doesn't make a good deal of difference. Start was off of the corner post by the dining hall.  Calculations made ahead of class indicated that the iOS users could not use their Compass app and the perform the experiment in seconds: Compass free does not display decimal seconds, and the distances are too small to impact seconds. The ten meter intervals are just too small. While there are undoubtedly other GPS apps for iOS, the iOS users are simple told to team up with an Android user. Taysh...

Latitude and longitude hide and seek

Image
Starting with the solstices and equinoxes presentation took too much time at 24 minutes. I ran out of time in the latitude and longitude introduction at 11:42 and had to try to pack GPS Essentials into the last eight minutes. The prime meridian was not well covered, time ran out. Solstice should perhaps move back to Friday perhaps displacing the traditional navigation play list. At the hide. Latitude: N 06° 54.509'   Longitude: E 158° 09.493'  Just below the dining hall, but I entered from the Daniel store side and crossed two valleys to reach this location. Austin was lead on the first and only group to find me group. Austin arrived at the hide by 12:15, a very fast find. He was careful to not be satisfied until all of the digits matched.  Kayla and Vandasia were part of the lead group, Vandasia was navigating with her own phone. Tayshaun and Valencia were also in the first group. Once we left the ...

8.2 Five marbles standard error of the mean

Image
Opened with working 7.3 homework.  9:13 and marbles were distributed. Marbles were pre-sorted. With the marbles distributed, roll was taken. No marbles were distributed after the roll. 9:16 and the third student. All 75 marbles distributed among 15 students were massed by  9:28.  Spreadsheet This term the 95% confidence intervals for all 15 samples captured the population mean. The population mean was also surprising: 5.1000 grams. Mathematically no more surprising than 5.1417, but for humans, surprising.

Foods of Micronesia

Image
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...
