These materials were developed to meet an expressed need for bilingual materials for a secondary school Life Science Course. Eight units were prepared. These include the following topics: (1) Introduction to the Scientific Method; (2) The Microscope; (3) The Cell; (4) Single-celled Protists, Plants, and Animals; (5) Multicellular Living Things; (6) Plants; (7) Animals; and (8) Genetics. Included are objectives, background material, lesson plans, evaluation materials, and activities. Many of these can be duplicated for classroom use. (RH)

This course guide is intended for classroom use by teachers of secondary level science to Spanish-speaking students of English as a second language (ESL). Both science instruction and acquisition of English scientific terminology are emphasized, within the framework of increasing overall student proficiency in English. The book is prefaced with a rationale to guide the teacher. Units present drills in repetition, substitution, and question answering. Topics covered include the metric system, matter and temperature, solutions, the microscope, the cell, mitosis, genetics, taxonomic classification, record breakers among animals, the human ear, the skeletal system, digestion, flowers and seeds, the structure of the earth, the water cycle, oceanography, astronomy, anthropology, and space exploration. Ample illustrations are provided,, laboratory activities are described, and Spanish translations of many assignments are provided to assist the student in mastering new terminology. (JB)

Instructional aids for classroom use and worksheets which may be reproduced for individual seatwork are included in these support materials for unit seven of the science/math strand developed for Spanish-speaking students in grade three. They are designed to be used with the teacher's guide to the unit, which contains a timetable for their use. The instructional aids and ditto masters are to help the teacher carry out instructional and assessment activities. The worksheets are to be presented under supervision rather than as independent tasks. Science materials pertain to activities about plants and animals, life cycles, birth and death rates, food chains, and adaptation; math materials encompass regrouping techniques for adding and subtracting two-digit numbers, measurement by ruler and yardstick, liquid measurements, telling time, line segments, points, intersections, and Roman numerals to XII. All classroom materials are in Spanish. (RS)

Instructional and assessment activities for unit seven of a science/math strand for Spanish-speaking students in grade three focus on the extended community. Activities support four spiraling questions on the elements, wants and needs, change occurrence, and results of change. For each activity, the focus, objective, and materials needed are listed in English and Spanish; detailed teacher instructions are in Spanish only. Content covers plants and animals and their means of survival; life cycles (reproduction, death); impacts of birth/death rates; Roman numerals to XII; the clock, calendar, days of the week, months, and seasons; harmful and beneficial insects; regrouping techniques for adding and subtracting two-digit numbers; ruler, yardstick, and liquid measurements; photosynthesis; nongreen plants; food chains of man/animals; how communities interact; interdependence of living organisms; ecosystem; construction of histogram and bar graph; and identification of line segments, points, intersections, and figures. Science concepts are variation, equilibrium, matter, energy, conservation, relativity, organization systems, interaction, adaptation, change, reproduction, force. (RS)

The teacher's guide for unit four of a Spanish science/math strand for second graders contains instructional and assessment activities for kits 13-16. Each designed for a two- to three-week teaching period, the kits' activities are geared toward guiding the child to discover correct answers through methods provided and, by putting materials in his hands, helping him discover facts through participation and use of reasoning powers. The guide lists focus, objective, and materials in English and Spanish for each learning activity; teacher instructions are in Spanish. Specific activities cover volume--gallon, quart, pint; fractions one-half and one-quarter; "more than" and "less than" symbols; comparatives "shorter than" and "taller than"; addition and subtraction combinations--missing addends, subtrahends, and operational symbols; commutative principle; subtraction as inverse of addition; parenthesis in addition combinations; plants--classification and germinations of seeds, function of parts of a plant, plant identification, usefulness to man; addition and subtraction of sets of 10-19 elements; missing addends and subtrahends; animals--characteristics, habits, usefulness to man; longitude--inches, feet, yards; three dimensional forms; counting by ones to 100; the five senses; change caused by environment and growing older.

Designed for use with unit four of the science/math strand for second graders, the supplement and ditto packet contain visuals, worksheets, and instructional aids referred to in the teacher's guide corresponding to this unit. The brief introductions to kits 13-16 are written in both English and Spanish; all classroom materials for students are in Spanish only. The illustrations and materials for seatwork by students pertain to concepts in math such as measurement of volume or longitude, comparison of numbers as to greater or smaller, addition and subtraction combinations, parenthesis in addition combinations, operational symbols, counting to 100, and money values. In science, the materials are to help the teacher present learning activities about plants; animals; use of the five senses to observe, manipulate, and describe; changes in objects caused by environment; changes in man caused by age; and classification of living and nonliving things. The worksheets are to be presented under supervision rather than as independent tasks. (RS)
