Promoting ACademic Excellence in Mathematics and Science for Workers of the 21st Century (PACE) was a consortium project made up of Indiana University Northwest, the Gary Community Schools, and the Merrillville Community Schools. The focus of this project was to prepare teachers and curricula for Tech Prep mathematics and science courses for the two school districts. The courses and course units prepared by the project are intended to promote the Core 40 Competencies of the Indiana Department of Education for High School courses. This document contains units for Physics and Physical Science designed to help students with a wide range of backgrounds and abilities learn physics. The Physics course includes the following units: (1) The Mathematics of Physics and Measurement; (2) Newton's Laws of Motion; (3) Electricity and Magnetism; and (4) Heat, Temperature, and Engines. The Physical Science course includes activities that link the traditional English, math, and physical science classes. Units in this course include: (1) Measure of Volume, Mass, Length; (2) Derived Measurements, Scalar Quantities; (3) The Chemical Industry; (4) Workplace Applications of Triangle Math; and (5) Motion and Energy.

The interest-based curriculum materials are designed to correlate the subjects of English, math, science, and home economics and infuse academic skills into the world of work. The House Care Science curriculum guide is divided into five units: (1) measurement, (2) household chemistry, (3) household electricity, (4) household machines, and (5) heat, light, and sound. Each unit is organized around objectives, experiments, evaluative material (unit exams), instructional materials, and references. The unit on measurement applies the metric system to density and specific gravity problems. The household chemistry unit activities deal with the three states of matter: solids, liquids, and gases. Principles of electricity are stressed in both the household electricity and household machines units, while the final unit on heat, light, and sound applies principles and theories relating to the use of energy in the home.

The SAVI/SELPH Program is the combined output of two projects funded by the United States Office of Education: Science Activities for the Visually Impaired (SAVI) and Science Enrichment for Learners with Physical Handicaps (SELPH). SAVI/SELPH is an interdisciplinary multisensory science enrichment program that has been used effectively with blind and visually impaired students, orthopedically handicapped students, learning disabled students, developmentally disabled students, emotionally handicapped students, hearing impaired students, and non-disabled students. The SAVI/SELPH program is composed of three major components: (1) printed activity instructions and other information materials for the teacher; (2) student equipment kits; and (3) an educational philosophy for incorporating science into the curriculum of disabled students. The printed activity instructions are included in this document. The SAVI/SELPH program includes nine modules. Each module encompasses a separate content area, and contains four or more activity write-ups. The modules include: (1) measurement; (2) structures of life; (3) scientific reasoning; (4) communication; (5) magnetism and electricity; (6) mixtures and solutions; (7) environments; (8) kitchen interactions; and (9) environmental energy. Each module contains an overview, activity description, science concepts, process skills, application skills, language development, related learning, purpose, materials, and pre-activity warm-ups for the teacher. Each activity includes an overview, background information, purpose, procedure, and follow-up. (KR)
The purpose of this project was to specifically identify important works within the National Bureau of Standards library collection of approximately 125,000 items that are generally acknowledged to be pertinent to the development of modern science and technology. Presented is an annotated list including 197 items selected from the pre-1900 holdings in the library. The arrangement is alphabetical by author, and the annotations describe the nature and significance of either the specific publication entry or its author in cases of multiple entries by author. The list provides a general cross-section of the collection and includes important works from the fields of mathematics, physics, electricity, chemistry, mechanics, metrology, and the history of science.
