Floral litmus solutions

This beauty soap would prove to be neutral. The soap had a gel like consistency.


This term the rapitest digital pH probe was used to obtain the pH of the known acid and base. 

The diluted lemon juice was 6.4. The dimethyl benzyl ammonium chloride cleaner was 9.3. 


The lab cart was used to haul gear. This also helped immensely with the clean up. The kettle was preloaded Wednesday afternoon. As was the coffee maker. The flowers were Spathoglottis plicata gathered the evening before. Lemon was the known acid, although post hoc Joe's place haf karer.

The set-up song was Haddaway's What is love?


The kettle was powered up by 07:15. This provided boiling water by 08:00.

08:01 and Jemira, Leona were present without flowers.

The slow open provided an opportunity to lay out the directions on a single board. The lab tables were once again referred to as lab benches to reduce confusion with report tables.

McGievens and Mor-Jacinta brought all three recommended litmus solution plants: Spathoglottis plicata, red hibiscus flowers, and red Coleus scutellarioides leaves. Jamira, Leona, Eytriann, and Moira on the right side.

No one else arrived with flowers except for a student with Ixora coccinea - a flower mentioned the day before as not working. 


Jamira and Mor-Jacinta testing unknowns

Jamira's shirt would be a stand-in for an acid result in the Friday quiz.


Stacy would be the stand-in for a basic result.

Alisha tests her solution against the known base. Meraia, Lidy-Loreen, and DeAnne observe.

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...

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...

Plotting polar coordinates in Desmos and a vector addition demonstrator

Image
In an earlier post I noted that Desmos did not directly plot polar coordinates. Not only was I incorrect, but Desmos responded to my blog to correct me! Although I had at some point seen that one could define a function f(x)=3x+5 and then have Desmos calculate f(6), I had not absorbed how this might be used to plot polar coordinates. The above works beautifully . Realizing that I could effectively program Desmos, I applied this thinking to demonstrating how to add two vectors when given the magnitudes m and the direction angles theta. The graph calculates the i and j components for the two vectors and then adds the vectors, graphically displaying the result while also providing information on the magnitude and direction of the vector sum. m1 and theta1 are the magnitude and direction angle for one of the two vectors, m2 and theta2 are the magnitude and direction for the other vector. All four are dynamically interactive and can be changed. The diagram purports to illustra...
