Through investigations of optical illusions, light, lenses, and the structure and function of eyes, they discover how the stimulus of light is received by the eye as the first step in getting the message to the brain. Each student then uses MRIs to put together a three-dimensional brain model, which is used as a reference throughout the rest of the course. Students then move on to brain function. Students map EEG recordings and learn that different parts of the brain are used for different functions. They investigate the receptors and the part of the brain that is involved in the sense of touch.
Students trace the pathway of information through the neurons from fingertip to brain and back.
Students revisit learning and memory, applying what they know about brain structure and function to refine and extend their knowledge of their own cognitive abilities. Students acquire a sense of the power and capability of their own brains. Earth History Evidence used to decipher Earth's prehistoric past is hidden in its rocks. Sedimentary rocks have sequentially recorded many Earth-shaping events and different environments over geologic time. These layers of rocks may be read much as one reads the pages of a book, although many of the pages and numerous characters are missing from this history, especially for the earliest chapters in the story.
