Floral litmus solutions

This term the need for limes and flowers only landed after the Ohm's law laboratory. Students were never told to bring flowers. The collapse in attendance at the end of Ohm's law left no opportunity to prep students. Limes were located and the ground orchids had come in heavy this season. Early morning load up was done because the intervening laboratory is in use at 11:30. Preloading water is also necessary. The layout was altered to reflect the loss of part one and the practical elimination of part two. There was only Spathoglottis plicata.  Soap and Zonrox replacement bleach were obtained at A1 during the morning set up. Daniel was out on the sidewalk Electrons were were in place for the morning lecture. This is day with many moving parts. Hydrogen introduction was already erased at this point. A one hour high speed crash and dash to hydrogen ions and hydroxide ions. At one hour th...

Ohms law

The electricity lecture opened with explaining the concept of potential energy and current using a waterfall.  The morning session moved to the presentation after one example was worked on the board. The laboratory notes were compressed on to a half of the whiteboard  Students missed the third clause. Perhaps these should be numbered explicitly. That there were three goals was missed by the class. This is also a generation that does not read. Students have never been good about reading directions, but this generation takes non-reading to a whole new level. Ellinae, Austin, and Jenry-Thor work on an Ohm's law rig. This rig had been set up by the instructor. Both the single and double battery values were already recorded. This gave the group only two more measurements to make: each group had only four batteries (cells). This would be the proximate cause of the attendance collapse. With their data in hand, they departed...

Optics

Early arrival at 7:20 to preload water was a fail this term. The power had been off since 5:00 PM the day before. This is one of the lecture-lab sequences with the most moving parts. Almost overlooked the mirrors. Water was a $10.50 purchase from A1 across the road. 12000 ml. Jed's has nothing larger than liter bottles and those were in the cold case. The 2000 ml graduated cylinders consumed a single bottle.  The cart is necessary to setting up efficiently. The oil immersion beakers are in the plastic container. They are kept separate as they are never completely degreased between terms.  This term features more diesel fumes than usual due to the El Niño westerlies. This will be the first term for the new prisms. Sometimes I feel so deserted was the setup opener. New 60° prism Spectrum. Barely. New laser set up. Didn't work as well as hoped for. Better to jus...
