Build real AP® Environmental Science skill one unit at a time, then prove it on a full-length practice exam.Practice to Mastery: AP® Environmental Science Workbook is a question-driven study book organized around the nine units of the current AP Environmental Science course framework. It contains 1,318 original practice problems: multiple-choice questions and free-response questions for every unit, plus a complete practice examination at the end of the book. Every problem comes with a detailed, step-by-step explanation or a point-by-point scoring guide.WHAT'S INSIDE- 9 unit chapters, one for each unit of the course: ecosystems and energy flow, biodiversity, populations, Earth systems and resources, land and water use, energy resources and consumption, atmospheric pollution, aquatic and terrestrial pollution, and global change.- 120 to 150 multiple-choice questions per unit, arranged from easy to medium to hard, so students can build confidence before moving on to multi-step, data-heavy problems.- 5 free-response questions per unit covering all three official question types: Design an Investigation, Analyze and Interpret Quantitative Data, and Analyze an Environmental Problem and Propose a Solution Doing Calculations.- Point-by-point scoring guides for every free-response question, showing exactly what earns credit, plus a complete example response.- A full-length practice examination: 80 multiple-choice questions and 3 free-response questions, with a score worksheet and a unit-by-unit breakdown so students can see where to focus.- Graphs, data tables, models, and passages drawn from realistic scenarios, the same kinds of stimuli students meet on test day.EXPLANATIONS THAT TEACHEach multiple-choice answer is explained clearly and completely: the reasoning, the science behind it, and every step of any calculation, with units. Explanations end with the key concept to remember, and questions that connect two units are flagged so students learn to link ideas across the course.PLENTY OF CALCULATION PRACTICEEnvironmental science rewards careful arithmetic. The book gives steady practice with percent change, the rule of 70, unit conversions, energy and power, trophic efficiency, half-life, per-capita figures, and scientific notation, all worked out step by step.WHO IT IS FOR- High school students taking AP Environmental Science who want far more practice than a textbook provides.- Students preparing for the AP exam in the final weeks who need targeted review by unit.- Teachers looking for a large bank of original questions for homework, quizzes, and review sessions.- Homeschool families and tutors who want a complete, well-organized practice program.ORIGINAL AND CAREFULLY CHECKEDAll questions, scenarios, data, and figures in this book are original. Scientific facts and every numerical answer were checked for accuracy, and answer choices are balanced so the correct answer cannot be guessed from its length or position.For even more exam practice, pair this workbook with its companion, Practice to Mastery: AP® Environmental Science Practice Exams, which contains 12 full-length exams with no questions repeated from this book.AP® is a trademark registered by the College Board, which is not affiliated with, and does not endorse, this product.
