These notes are broken up into 4 parts: Waves, Sound, Light and Electromagnetic Spectrum. Each have both complete and skeletal versions of the notes. The complete set is what I put on my overhead for students to copy. They receive the skeletal set and fill in the blanks. They add questions to the side of their notes to use them to study. I usually break these notes up over a couple of days - a few minutes of class here and there - when we reach the next part of the unit.
