44 Sometimes it is easier to go to school than to write lesson plans for a sub and explain to a couple of different teachers how to proctor an AP makeup test. Especially after getting in after 10 PM and already feeling sick. But even with a steady intake of decongestant and expectorant, I felt miserable today with a head cold. So instead of actively teaching, I showed part of part 1 of The Elegant Universe. I wanted the conceptual-level kids to see the “electromagnetism is stronger than gravity” bit and the four fundamental forces of the universe in particular, since we are still in the Balanced Forces unit. We’ll talk about this stuff more later.
