Physci day one and two with density

Day one was still in the add/drop period with three of eighteen absent. Coverage focused on the course syllabus, calendar, learning outcomes, and the nature of the course. 

Tuesday started with tech Tuesday, app downloads, app demonstrations, and submitting screenshots. Then measurement and density were introduced. 

Tuesday morning opened with coverage of what apps to download. The introduction overlooked coverage of the screenshot assignment. Then the metric system and measurement were introduced. 

The introduction began with space, time, matter, and energy. Energy was then set aside. Typical variables were listed followed by the metric system units used for those measurements, both MKS and CGS. The concept that one cubic centimeter is one milliliter of water and is one gram was introducted. 500 ml bottles of water were massed, with the newer bottle coming in at 501 grams. Two 500 ml bottles massed 996 grams, just shy of a kilogram. 

Then density was introduced, including that the density of water is one gram per cubic centimeter. Following this the metal blocks were massed, which led into coverage of floating versus sinking based on density.

Soap was purchased the weekend before, an eclectic mix of soaps from Yoshie.


In the laboratory session the demonstration was done differently. Instead of splitting the demonstration into two separate demonstrations - one up front on how to gather the data and one late in the period for how to do the report - the demonstration was a non-stop beginning to end demonstration. Including carving the Lux Magical Spell soap into the rectangular slab. 


After carving the slab, the first data point was recorded on the board. The rest were entered into Desmos and later displayed on the SmartBoard using SmartMirror and the Tripltek tablet. The tablet, running Android 10, holds a connection to the SmartBoard better than newer versions of Android.

Desmos

Five data points were recorded. The intact Lux Magical Spell bar is a scant 80 grams. Carving to a shape close to a rectangular slab left only 48 grams. Four cut-downs left only 26 grams of soap. 


The data value at (0 cubic centimeters, 0 grams) was intentionally not included. Data was entered on the Tripltek while seated at the west end of the center table. The table was preset with variables, the graph axes were labeled prior to class. 


With Desmos set up, the tablet was linked to the Smartboard. On the tablet screenshots were made as seen above. Then a new Google Docs document was opened and the assembly of the laboratory report was done on the tablet and mirrored to the Smarboard. 


The SmartBoard is displaying take-a-screenshot.org. Jenry-Thor, Arnold, and Ellinae work on carving their soap into a rectangular slab. Seniko watches Arnold, Austin makes notes.

Arnold continues to trim the soap with Seniko watching. 

All soaps are now sinking soaps. Ivory stopped producing aerated floating soap circa 2023.

Setting up a boxplot chart in Google Sheets with multiple boxplots on a single chart

Image
The  Google Statistics  add-on for Google Sheets can display multiple boxplots in a single chart. The key is the layout of the data. One column should be the variable by which the data is to be grouped, the other column should be the data to be box plotted. Set up the Statistics add-on with the data to be plotted as the variable, and the grouping column as the "by" variable. In this image I had deselected all but the boxplot option, the result was the appearance of the Moment, Standard errors, and Confidence intervals options. The default is apparently a 95% confidence interval for the mean. The result is multiple boxplots on a single chart with a common scale. The new tab that is created also quotes 95% confidence intervals for the mean. Note that as of 2018 the Google Statistics add-on cannot be found by search in the add-ons. In addition, as of May 2018 the add-on no longer verifies, possibly due to the add-on not having been updated since August 2017. One may ha...

Traditional food dishes of Micronesia

Image
Clara, Jennette, and Joanie presented ground hard taro cooked in an umw, effectively a hot rock oven. Pohnpeian: rotama. Pingelapese: sero. Mwoakillese: rodma. Mortlockese: Amahd. Kosrae: rodoma. After cooking in an umw the rotama is pounded with the petiole of a palm frond. Rotama is made from hard or swamp taro, known as mwahng on Pohnpei, mweian on Pingalap, pula in Mortlockese, and pahsruhk on Kosrae. In traditional times on the outer islands the women had primary responsibility for tending the taro while the men handled fishing and climbing tasks. Joesen and Noeleen presented fermented breadfruit from the outer islands of Yap such as Woleai and Eauripik. The raw ingredients were actually brought in from Yap, Noeleen prepared the maare.  The leaf wrap is ti leaf - Cordyline fruticosa. Pauleen, Barnson, Trisha, Verginia, Con-ray, and Maylanda from Kitti, Pohnpei brought in mahi umw, koahpnoair koakihr, and uht sukusuk. Above is breadfruit umw, mahi umw, o...

Experimenting with the PlantNet and iNaturalist apps

Image
The application of image recognition technologies as the back end to botany apps is providing increasingly relevant search results. Over the recent winter break I began looking at whether the apps now available might be useful to the ethnobotany class here on Pohnpei. Some apps had a more regional focus in the past and were better at north american or european plants. Pohnpei has a both unique indigenous plants and many introduced plants from around the world -  a challenging environment for any image recognition system. A student working with a plant identification app for the first time My criterion was that the app had to be appropriate for use in my classroom. The app could not contain advertising and the app had to be free, my students typically do not have the ability to pay for an app. The app would also have to be fairly small as my students often use phones with limited memory and processing power. I settled on PlantNet and was impressed with the ability of the a...
