I was going through my books today and rediscovered a wonderful reference for class. It's called The Scientific American Day in the Life of Your Brain. It takes a person from 5 am and waking up, what brain chemicals are activating us and other sensory issues. It goes on to deal with coming to consciousness, morning emotions, directions to work, facing others, performance at work/stress, decision making, the hungry brain, the tired brain, boredom, pain, exercise, the dimming of the day, getting home from work, music, humor, love and lust, getting to sleep, falling to sleep, sleeping and problems, and people who have to work at night. The book is at a reading level appropriate for those of use brushing up on brain science as well as high school students.
In short, take any person on any day and the book will have a section on what is happening in a person's brain. I can imagine a creative teacher, with proper resources, making this a class assignment--what is going on with the brain and rest of the biology of humans during each part of the day, and dividing it up like the chapters/sections of this book. If you do that, just keep this book hidden ;)
