CHEMISTRY: Fun field trip today! What? There really aren’t tiny people living in boxes above the doors at Wal-mart? Good job coming up with examples of the photoelectric effect. I had forgotten all about those automatic flush toilets! 🙂
What did you think about the problems? Again, make sure you not only memorize formulas, but also be careful to learn the symbols and units for each of the quantities you’re going to use, it’s easy to get them confused. Here’s the lecture from Thursday – photoelectric effect and then problems at the end.

The elevator thing was really amazing yesterday. I enjoyed that you were magical and the “elevator whisperer”. I would of never thought about the sensor for the elevator doors!
