Acceleration

The morning opened with a review of laboratory two velocity. An introduction to acceleration as a change in velocity. A request to sketch the shape acceleration will produce on a time versus distance graph. Only one curve. Ten linear lines.


The morning acceleration from zero produced an acceleration of 0.24 meters per second - half of the values seen historically, but this is due primarily to the new start at the LRC which allows a more leisurely acceleration and a longer duration of acceleration. I had forgotten that I setup calculation of the velocity in Desmos, so the orange line was not there during class. 


The above was what was shown to the class. 


High speed swizzling is not possible with a groin strain. And the wobbly turn around was also hard with my muscular issues. Old age coupled with an unwillingness to let the muscles recover with reinjury. This run should not have been done. A timing mark was completely missed and the inbound velocity was too low to get past nine meters. There was extra time, but filling it with this was a bad idea this summer. 


Duplication of the prior term Desmos was overlooked, hence the prior term Desmos is now corrupted by some data from this term. These Desmos files are set up to automatically calculate averages of the median values gathered by the students. 


Predictions reflected onto the board.


A failed attempt at explaining the second run - just not enough time to develop the material that usually lands on a Wednesday and is usually referenced as exercise 031.

Drops from four and five meters



Friday opened with Bernoulli, a strip of paper, and ping pong balls in funnels. The Magnus effect was also demonstrated.

Then a segue to a 1968 science demonstrations text, a 1991 graphing calculator, and a 1995 digital camera. A brief scan of technology and then an introduction of NotebookLM and how to set it up. By the following weekend a plan for how to actually use NotebookLM with laboratory reports was released.

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...
