Overview

The ScienceWiz(R) Online Discovery Sound flip book (48 pages) and kit begins by exploring sound vibrations and culminates in the building of a working Edison phonograph. That phonograph lets you not only capture sound vibrations but it also lets you play those vibrations back. We have only been able to do the latter for the last 150 years. There is still a rumor that Abraham Lincoln's voice may have been captured on a carbon print. That voice print has not been found -- yet. The online flip book (48 pages) blends highly visual instructions for hand-on projects, videos, digital apps, animations, simulations and games. This integrated approach gives your child guided access to a decibel meter, an audiometer, a frequency generator (for visualizing pitch and frequency) and creating sound patterns in sand and an interactive model of the human ear. This equipment would have cost many thousands of dollars in the past. It is fascinating to be able to use these tools to explore sound without that cost. PROJECTS INCLUDE: Building an Edison style phonograph Measuring the loudness of sound with a digital decibel meter Using an audiometer to test your own sensitivity to sound Hearing and transmitting sounds many adults cannot hear Vibrating your vocal cords and a kazoo Visualizing your voice print with a digital app Playing the sound location game Transmitting sounds through solids, liquids and gases Determining if sound waves travel through a vacuum Using a slinky to model sound waves Bouncing, absorbing and amplifying sound vibrations Listening to your heart beat Exploring how your ear works Changing and visualizing pitch and frequency Discover if fish have ears, what dogs can hear and how dolphins, whales and bats use sound. Spin a sound tube to Doppler shift sound. Explore and simulate the doppler shift online.

Author Information

Penny Norman, Ph.D. earned a doctoral degree in Biophysics from U.C. Berkeley. She became involved with the development of primary grade science materials through volunteer work, which she began as her own children started school. During this process she became deeply concerned about the limited exposure of elementary age students to the physical sciences. Her concern has translated into a 20 year effort to test and revamp science materials for the primary grades. Her work with children developed into a product line initially under the auspices of grants from the National Science Foundation and the Franklin Foundation. Her published titles reflect Dr. Norman's extensive testing and involvement with children and teachers and her love and commitment to both. Ann Einstein, M.A.T. from George Washington University in Washington D.C., was a teacher in the Berkeley Unified School District. She has been involved with the education of children for most of her adult career as a director of early childhood education programs, as a teacher in gifted and talented programs and most recently as an elementary education teacher. She has been an editor of the ScienceWiz(TM) Books since 1994 when she edited the ElectroWiz(TM) Electricity book. Ann brings a clarity of mind and the capacity to see things through a child's eyes to the editing process. To quote an Einstein of an earlier generation: We never cease to stand like curious children before the great Mystery into which we were born. - Albert Einstein
