When I give notes I always try to have a video clip or animated webpage to view. Set a time limit on your self. We can take a lot more time than we think when talking. Today I gave notes on force and Newton's 1st law. I kept it short and put in 2 four minute EUREKA series videos and visited a cool website that shows animations explaning how Galileo used a thought experiment to create the law of inertia. It was per fect mix of notes, video and web.
Hope this helps,
