A RFRT rnrov AVAII API 1 Greetings from 3M and NEWTON'S APPLE E) NEWTON'S APPLE continues to provide innovative, fun, and meaning- ful programming for young people. At 3M, we believe early exposure to science increases interest and appetite for learning, and helps foster appreciation for the importance of and opportunities in science. We're proud to sponsor the 14th season of NEWTON'S APPLE. An important aspect of 3M's sponsorship is our work with KTCA-TV and the National Science Teachers Association to produce these NEWTON'S APPLE classroom materials. These materials help bring to life the wonder of science and can instill greater curiosity about science, our world, and our future. EI LEEN GALINDO Actress and comedienne Eileen Galindo joins the NEWTON'S APPLE L.D. DeSimone team in its I4th season. Eileen travels to Switzerland to investigate how Chairman and rescuers find people buried in avalanches. She then goes to the Andes Chief Executive Officer mountains in Peru to learn how the ancient Incas used special beads called 3M quipus to communicate. In the Warehouse, Eileen learns the art of soccer from a physicist and she gets her hands on some very valuable gems.

MADE POSSIBLE BY A GRANT FROM 3M. /Focusing on the Science Education Standards The NEWTON'S APPLE educational materials were developed to help teachers approach some of the goals of the new National Science Education Standards. The National Science Education Standards, recently published by the National Research Council, presents criteria to help state and local school personnel make decisions about every area of science education. From teaching and the quality of what students know to assessment practices and the system that supports teachers and programs, national standards bring coordination, consistency, and coherence to the improvement of every aspect of science education. The National Science Teachers Association (NSTA) applauds the release of the National Science Education Standards, and encourages science educators to put the Standards into practice in the classroom. The world's largest organization dedicat- ed to science education, NSTA has led the way in promoting the Standards with teacher institutes, awareness kits, and a Standards discussion area via the Internet. NSTA also has developed many publications to keep educators informed about the latest issues in science education, including a variety of resources for imple- menting the Standards. This year, NSTA presents its Pathways to the Science Standards, practical guide- books for bringing the standards to life in any school or classroom. Written by teachers for teachers, these books include examples, discussions, and demonstra- tions on how you can carry the vision of the Standardsfor teaching, profes- sional development, assessment, content, program, and systeminto the real world of the classroom and school. Pathways is also a tool for you to use in col- laborating with administrators, school boards, and other stakeholders in science education. Separate editions treat elementary, middle, and high school levels. NSTA's project on Scope, Sequence, and Coordination recently updated its High School Framework for National Science Education Standards to help teachers imple- ment the Standards within the SS&C model. A Framework for High School Science Education demonstrates how the content standards can be sequenced and inte- grated over the four years of high school. Integral to this publication is a series of "micro-units" that corresponds to the elements of the Framework's learning sequence. These micro-units consist of lab activities, readings, and assessment items that will help you put the national standards to work in your classroom. The Standards; elementary, middle level, and high school editions of Pathways; and the SSe-C High School Framework are available from NSTA. For a catalog and sales information, contact the NSTA Science Store at (800) 722-NSTA (6782) between the hours of 8 a.m. and 6 p.m. (EST).

Index to the 14th Season Lesson Pages There are two way to locate any of the 25 lessons in this guide: check out the ApEwilyNi alphabetically arranged subject index found on the inside back cover, or look through the numerically arranged show index on this page. Either way, once you've identified a topic you'd like to explore, look in the upper right-hand corner of each lesson page for the NEWTON'S APPLE show num- ber (e.g., 1401, 1402) that corresponds to that topic. We've also included in the same corner the segment's approximate running time. On the back of this page, you will find a guide to the past three seasons of NEW- TON'S APPLE. These episodes may be. rebroadcast on your local PBS station throughout the year, and we hope you will continue to use them in your classroom.
