A brief and neutral 20 minute introduction to the active ingredient in betel nut, the advice to use traditional psychoactive compounds in their traditional manner, the problem with adding a cigarette to one's chew, and the issue of a genetic sieve. Then I ran the current variant of the playlist. This term I dropped the France TV Taiwan report swapping in an older report out of Papua New Guinea. For the outro I spoke on the impact on children the loss of a parent has. 

Ohm's Law

The unit in electricity began on the Friday of optics week with the first 50 minutes of shock and awe. On Monday Power comes in many forms. Wednesday deployed the presentation on electrical appliances. Power price was not yet updated. The high head microhydro provides a good introduction to current and voltage for Wednesday. Wednesday used the electrical device slides to determine the cost of various appliances.  A 330 Ohm resistor in one of the breadboards Che'chemely and Charla setting up Emlyia and Kapualani also setting up Fumie-Kate testing a circuit. Emylia makes a measurement, Sucie and Kapualani record results.  Margrett makes measurements, Mirabella records data.  Shawn Dee and Darsen setting up a circuit. Delailah discussing results.  Delailah recording data Che'Chemely and Charla reading the multimeter...

Optics reflection refraction

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:...
