Today was the taco party. Four years ago, one of my students left a bottle of taco sauce in my room. The bottle was brought for a fiesta in Spanish class but was never opened. The students had opened up a jar of salsa instead. So the bottle sat in my room for a while. Then I started having students turn in their labs right next to the taco sauce. Later, the taco sauce ended up on a top shelf. This year, we realized it expired in February of this year, and we planned for a taco party.
Today was the day. We had lots of sugary treats, some nacho chips and taco meat, and no plates. We managed.
We also took a test, whiteboarded the last, relatively straightforward problems about pendulums, and played a little bit with the long slinky. We're moving on to mechanical waves tomorrow.
