Optics

Holidays on Monday and Wednesday week thirteen led to the reversal of electricity and optics. Electricity has a two day introduction that is more necessary. Optics of reflection and refraction can be done on a cold open laboratory.

Set up included water being preloaded on Tuesday to end run the holidays and the possibility of the water being off. The setup song was Sometimes I feel so deserted. 

Board was set. Then a brief introduction to total internal reflection and the disappearing coin and beakers

Bracey estimates the location of the image in the mirror


Ashton indicates the image location while Damien measures the distance behind the mirror. In theory the object distance is equal to the image distance, but a slope of exactly one is almost surprisingly rare.

Grace Marie estimates the apparent depth of a penny underwater in a graduated cylinder. The apparent depth in water columns of different heights leads to an estimate of the index of refraction for water.

Youlanae Maia works with a second graduated cylinder. Iryann holds a third cylinder. Each cylinder has different amounts of water.

Moki estimates the image depth of the penny while Kayla records data in Desmos 

Travis with the third cylinder. The water tank to the left is a fourth data point.

Moodle bulk grading of manually marked quiz and test questions

Image
Manual marking of an essay type question on a quiz or test in Moodle can be done student by student but that process involves a lot of clicking and scrolling as one has to open each student's submission. There is a bulk marking screen available. In the test or quiz click on Results. At the upper left side is a stealth drop down list menu under the word "Grades" that includes the option "Manual grading." Choose manual grading. On the far right click on the blue "grade all" hyperlink. That will open up a all of the submissions for question one on a single page. One can now mark all of the question one submissions manually for all students in the course.

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...

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...
