2 Introduction Macmillan/McGraw-Hill Georgia Standards Test Preparation in Science is a comprehensive program designed to familiarize students with standardized testing and to review the concepts covered in Macmillan/ McGraw-Hill Georgia Science. About This Book The questions in this book will accustom students in a grade-appropriate manner with standardized testing and the Georgia science standards, in preparation for the Georgia Criterion-Referenced Competency Tests (CRCT). Correlation Chart: This chart illustrates how the Georgia science standards covered in this book coincide with chapters and lessons in Macmillan/McGraw-Hill Georgia Science. Diagnostic Tests: The diagnostic tests are helpful tools designed to simulate the statewide test that students will be taking. Each test is comprised of 30 multiple-choice questions that cover the span of Georgia science standards. These science standards are tested in the same format and proportions that students will likely see on the actual CRCT Science test. Standards Tests: The practice tests give students the opportunity to answer questions that focus on a particular standard and the indicators that comprise each standard. The practice test questions assess Life Science, Earth Science, or Physical Science standards and also focus on the importance of the Characteristics of Science standards, which are emphasized in each of the tests. These tests can be used as pretests and posttests, chapter tests, homework assignments, or as extra practice. How to Administer the Practice Tests Remove the practice test pages from the book and photocopy them for students. Answers are marked in non-reproducible blue ink for all questions. Instruct students to mark their answers directly on the test pages. Separate students desks so that students can work independently. Tell students that they are taking a practice test and ask them to remove everything from their desks except for several pencils. They may not speak to classmates until the test is over. Keep the classroom atmosphere as much like the administration of a standardized test as possible. Minimize distractions and discourage talking. ii Correlation Chart

4 Correlation Chart Standards and Indicators Characteristics of Science Habits of Mind S1CS1. Students will be aware of the importance of curiosity, honesty, openness, and skepticism in science and will exhibit these traits in their own efforts to understand how the world works. a. Raise questions about the world around them and be willing to seek answers to some of the questions by making careful observations and measurements and trying to figure things out. S1CS2. Students will have the computation and estimation skills necessary for analyzing data and following scientific explanations. a. Use whole numbers in ordering, counting, identifying, measuring, and describing things and experiences. b. Readily give the sums and differences of single-digit numbers in ordinary, practical contexts and judge the reasonableness of the answer. c. Give rough estimates of numerical answers to problems before doing them formally. d. Make quantitative estimates of familiar lengths, weights, and time intervals, and check them by measuring. S1CS3. Students will use tools and instruments for observing, measuring, and manipulating objects in scientific activities. a. Use ordinary hand tools and instruments to construct, measure, and look at objects. b. Make something that can actually be used to perform a task, using paper, cardboard, wood, plastic, metal, or existing objects. c. Identify and practice accepted safety procedures in manipulating science materials and equipment. S1CS4. Students will use the ideas of system, model, change, and scale in exploring scientific and technological matters. a. Use a model such as a toy or a picture to describe a feature of the primary thing. b. Describe changes in the size, weight, color, or movement of things, and note which of their other qualities remain the same during a specific change. c. Compare very different sizes, weights, ages (baby/adult), and speeds (fast/slow) of both human made and natural things. S1CS5. Students will communicate scientific ideas and activities clearly. a. Describe and compare things in terms of number, shape, texture, size, weight, color, and motion. b. Draw pictures (grade level appropriate) that correctly portray features of the thing being described. c. Use simple pictographs and bar graphs to communicate data. Chapter in Macmillan/ McGraw-Hill Georgia Science Characteristics of Science standards are featured throughout the book. iv Correlation Chart

5 Teacher Notes Standards and Indicators Characteristics of Science The Nature of Science S1CS6. Students will be familiar with the character of scientific knowledge and how it is achieved. Students will recognize that: a. When a science investigation is done the way it was done before, we expect to get a similar result. b. Science involves collecting data and testing hypotheses. c. Scientists often repeat experiments multiple times and subject their ideas to criticism by other scientists who may disagree with them and do further tests. d. All different kinds of people can be and are scientists. S1CS7. Students will understand important features of the process of scientific inquiry. Students will apply the following to inquiry learning practices: a. Scientists use a common language with precise definitions of terms to make it easier to communicate their observations to each other. Chapter in Macmillan/ McGraw-Hill Georgia Science Characteristics of Science standards are featured throughout the book. b. In doing science, it is often helpful to work as a team. All team members should reach individual conclusions and share their understandings with other members of the team in order to develop a consensus. c. Tools such as thermometers, rulers and balances often give more information about things than can be obtained by just observing things without help. d. Much can be learned about plants and animals by observing them closely, but care must be taken to know the needs of living things and how to provide for them. Advantage can be taken of classroom pets. Earth Science S1E1. Students will observe, measure, and communicate weather data to 3, 4 see patterns in weather and climate. a. Identify different types of weather and the characteristics of each type. 3, 4 b. Investigate weather by observing, measuring with simple weather instruments (thermometer, wind vane, rain gauge), and recording weather 3, 4 data (temperature, precipitation, sky conditions, and weather events) in a periodic journal or on a calendar seasonally. c. Correlate weather data (temperature, precipitation, sky conditions, and weather events) to seasonal changes. 3, 4 Correlation Chart v

6 Correlation Chart Chapter in Macmillan/ Standards and Indicators McGraw-Hill Georgia Science S1E2. Students will observe and record changes in water as it relates to weather. 4 a.
