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. It is up to the clever and imaginative student of geology to put the pieces together, interpret the clues, and reconstruct the missing parts to tell Earth's story. The Grand Canyon provides one of the best places on the planet to begin looking back into Earth's history.
