Developed especially for migrant children, this field-tested curriculum teaches the benefits and hazards of pesticides to intermediate grade students. Materials, prepared in Spanish and English, can be used as a separate science/health unit on pesticides or integrated into the regular math and reading curriculum. Topics include benefits of pesticides, packaging and warning labels, application methods for fields and homes, specific hazards such as pesticide storage areas and contaminated irrigation water, and steps to take in case of pesticide contamination. The Level 4 Unit gives background information for teachers, a detailed course for instructing children, 15 visuals, 4 true-false tests, and an illustrated pamphlet for parents. The unit is organized under 16 pesticide concepts with teaching materials, activities, and reading and math skills outlined for each concept. Activities include designing pesticide container labels, weighing seeds, and completing the math and reading skills activity sheets included in the guide. The 45 reading and 13 math skills covered in the unit are taken from and cross-referenced to the National Migrant Education Program of Reading and Math Skills. Reading skills range from prefixes and suffixes to dictionary use, and outlining. Math skills include multiplication, percentages, weights/measures and the metric system. (JHZ)
