Man, so I realize no one writes stuff here, so no one probably reads it.  That will not deter me.  I had a great moment today!  One of my students came in excitedly saying, "Miss Cunningham! Guess what I did yesterday?!" I asked her, and she told me about how she went to a talk the day before on a new underwater camera.  The man speaking talked about the index of refraction of water and how that was the key to designing the lens he used, and how the lenses were oriented in the camera.  She was excited that she understood what he was talking about after learning about lenses and indices of refraction in Physics.  She even got to explain some of it to her sciencey mom.  Made me feel good to be a teacher.
