Optics reflection refraction

Image
This term optics was reduced to a single day wedged between blue light  black light microplastics, and Shock and Awe: The story of electricity . A tube was used for filling, moving apparent depth to the north table. A glass dish not preview used was also deployed. In the 1000 ml cylinders I used Sacagawea coins. These slide more readily for centering at the bottom than pennies. Despite being larger than external penny, the use of the Sacagawea was functional. Morning indices of 1.27, 1.29, and 1.36 were obtained. The 11:00 section did worse with indices from 0.9 to 1.75, only a single group near 1.33 at 1.27. Anecdotally the 11:00 section each term seems to generate larger errors than the 8:00 section. Before one dives into a deep analysis, today there were 11:00 section students who attended at 8:00 and 8:00 section students who attended at 11:00. The difference is not necessarily linked to the students who enroll in these sections. This is not a case of 8:00 s

Fruit salad fruit type identification

Image
I had thought I used two medium sized cans of tropical fruit spring 2024, but I had forgotten that I upsized in the wake of running out in a prior term. Although I had forgotten this detail, I still fortuitously chose the largest can available at A1 Mart. I had also picked up five small cans of fruit from Ace Office supply. I forgot to check Ace Commercial for nata de Coco, and A1 Mart was out.  The small can second from the right above has a picture of many kinds of fruit and is marked in Japanese only. Despite the label, the can contained pear chunks only, nothing else. And the pear chunks were off color, darker and grayer than a pear chunk should be. They were not expired and tasted just fine, but I did not add them to the bowl. I shifted to a large metal bowl this term. The lids were all pop top lids on the small cans. I began setup at 3:00 including a cold boot of the SMARTboard. I finished fruit distribution at 3:29 and used the videos to distribute paper

112 Color of light

Image
Week eleven had only a Wednesday and Thursday class due to holidays. After much thought, I chose to dump the Limits of Light and go straight into spectrum using CD spectrograph boxes. I used this to lead a discussion on how many colors students saw. Students listed six colors, although one box showed a magenta fringe beyond purple. This led into the lecture on science as what we can see, what we can measure. I had forgotten to move a microscope on Wednesday afternoon, so I moved one early on Thursday morning. This term I brought the Blackview. This worked better than the Pixel due to larger pixels.  One suggestion is to rework the screenshots to use c1 in lieu of just c for the color variable. I did that in class.  Mirabella graciously let me take a picture of her yellow shirt with the Blackview phone. I am reminded I should wear a yellow overshirt so I can take it off and put it under the microscope.  Under the microscope the Blackview showed only red and green
