Carnegie Mellon University is developing an interactive, multimedia planetarium presentation about the human brain. The interdisciplinary project team will build upon and refine the experience gained from its recently completed planetarium show, Journey Into the Living Cell. The context for this work is the need for increased public understanding of the human brain - an organ central to the very concept of humanity. The understanding of the human brain is located at the lively crossroads of research in many disciplines, including psychiatry, psychology, neuroscience, computer science and biology. The proposed medium to address this important issue is a 45-minute planetarium show. A broad audience ranging from pre-adolescent to adult will be targeted. Sophisticated and entertaining imaging technologies, including animation and virtual reality, will be used throughout the work. Narration and sound will be tightly integrated into the work. The hemispherical display surface of the planetarium will be fully utilized both visually and sonically. Recent advances in the brain sciences as well as long held understandings about the brain will be presented. Basic brain biology and principles of brain function including cooperativity in brain region activity and brain region specialization will be introduced.

This project develops an 8-week middle-school mathematics module that introduces cryptography, the science of sending secret messages, while teaching and reinforcing the learning of related mathematical concepts. The topics range from the classical encryption systems and the historic context in which they were used through powerful modern encryption systems that provide secrecy in electronic messages today. The module also covers passwords and codes that correct errors in the transmission of information. Public awareness of the importance of cryptography is growing, as is the need to understand the issues involved. The study of cryptography provides an interesting context for students to apply traditional mathematical skills and concepts. Mathematical topics covered include percents, probability, functions, prime numbers, decimals, inverses and modular arithmetic. The main product is a middle-school student book, with accompanying teacher materials. A web site is being developed that supports the activities in this book. Abbreviated modules for Grades 3, 4 and 5 are also being developed, as well as an instructor's guide for adapting the materials for use in informal educational settings such as museums and after-school programs. The development of the module involves piloting and field-testing by experienced classroom teachers from diverse school communities and instructors of informal educational programs. Evaluation includes review by mathematicians and educators, as well as an investigation into the level of students' understanding of the topics studied.
