Periodic table and floral litmus solutions

Monday saw a correction to spring 2025 when the lecture moved all too quickly into bonding. Monday started with hydrogen. Then deuterium and tritium were covered. Following this diversion into isotopes, Helium was diagrammed. Helium introduced electron spin and the idea of full shells. S, p, d, f orbitals were briefly mentioned, the Lithium was diagrammed. This wrapped up the period on Monday. This approach permitted time to introduce concepts.  Wednesday was used to introduce bonding, starting with hydrogen-hudrogen. The shatterballs were used.  Starting from hydrogen the jump was made to carbon. Methane was diagrammed followed by ammonia. Then carbon dioxide was attempted. Running low on time and board space, water was the final diagram. Hydrogen ions (protons) and hydroxide ions were covered next. This segued into a definition of acid and bases. Once again the reality of hydronium ions was skipped over. On Thursday a solo on t...

Ohm's law

On Monday Power Comes in Many Forms was shown to provide the segue into voltage and current on Wednesday. Wednesday picked up from the high head micro-hydroelectric project to introduce voltage and current. This term the front side definitions introduction ran too long and the class did not do more than two appliances. The class also did not visit the solar panel output display. This means that the lecture must be compressed if the panel is operation. In retrospect the cause of the overly long definitions introduction remained unclear. As a result the presentation on appliances was also not shown. The double failure to work more appliances and visit the solar panel output should be remedied with a faster roll into that material. The presentation now has a complete front end introducing voltage, current, resistance, and power.  The new ratcheting driver is too wide to open this multimeter. The Vapira CO2 kit includes the needed driver. A permane...

Center for Entrepreneurship hydroponic facility and demo garden

Image
The SC/SS Ethnobotany class visited the Center for Entrepreneurship Demo Gardens at the College of Micronesia-FSM on Thursday 13 November. The class was also given a tour of the hydroponic facility and briefed on future directions for the facility.  Welbert Washington introduces the facilities to the class. Beverly, Kimberly, Maryam, and Crystal Dannia Route explains processes in the hydroponic facility. Kimberly on the right. The open areas are due to a systems changeover in progress at the facility. Tower units are being brought in. The existing systems have been distributed to local high schools. One of the current systems with bok choy, Napa cabbage, and lettuce.
