Heat conduction

The week started off with a heat and temperature video done in 1980 by Ontario TV in Canada that still does a nice job of covering the difference between heat and temperature for an ESL audience. The video tape is apparently no longer available, but the video lives on in YouTube space, at least episode 20 and 21. A search for the other videos we watch (16 to 21 inclusive) can be done to find the rest.


Wednesday I covered movement of heat in liquids (convection), movement of heat in solids (conduction), and movement of heat as electromagnetic radiation. I then did a series of demonstrations of temperatures, including my own. As usual the room temperature was 28 Celsius.

Senioreen watches for temperature rise in laboratory six

Laboratory six had the students exploring conductivity of heat and then presenting chart choices to the class.

Larry being authoritative. 

Maria-Asuncion presents her group's chart choice

Sepe Valton Palsis presented with her usual style and flair

Roselino and Hyrum settled on a column chart with a third column that showed the change in temperature

Bireen presented a more traditional two column chart solution (start and maximum temperature)

Gayle, working in the afternoon, shows a two column solution

Frauleen explains an xy scattergraph solution where the start temperature is the x-coordinate and the maximum temperature is the y-coordinate. A line of equal start and max temperatures denotes insulators. Distance from that equal temperature change is proportional to conductivity, at least theoretically.

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...

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...
