This workbook contains practice problems to help you test your science knowledge and reasoning skills in preparation for taking the GED Science test.

Start your science practice by taking the Science pretest at the beginning of this workbook. It will help you decide which chapters of the workbook will be most valuable to you. Take the pretest in a controlled environment, with as few distractions as possible. If you want to closely simulate testing conditions, limit yourself to 90 minutes. When you are done, or when time is up, check your answers in the Answers and Explanations section at the end of the pretest. Next, find the problem numbers you answered incorrectly in the Evaluation Chart to identify the chapters on which you need to concentrate.

Each of the three chapters in the book has dozens of questions on one of the three content topics that are part of the GED Science test. The questions have also been carefully designed to match each of the following:

the test content

the depth of knowledge (DOK) levels that are used to measure how well you understand each topic

the Common Core State Standards (CCSS) that you are expected to have mastered

The exercises are not intended to be timed, but if you find that you are familiar with a topic, you could try timing yourself on a few problems, attempting to correctly work 5 questions in 10 minutes, for example. Answers for the exercises are located at the back of the workbook.

Finally, when you have completed the last exercise, take the Science posttest at the back of this workbook. This test can help you reevaluate yourself after practicing as much of the workbook as you feel is necessary. Answers are located at the end of the test, and another evaluation chart is provided to help you decide if you are ready to take the GED Science test or where you might need further practice.

At the back of the book, you will find a glossary of important terms to know for the GED Science test. You can use this while you study or as a tool to help you review right before the test.

The GED Science test is a computer-based test, which allows for a broad range of item types. There are many multiple-choice items; each has four answer choices from which to choose. There are also many technology-based items with formats such as fill-in-the-blank, drop-down, and drag-and-drop.

Fill-in-the-blank: These are short-answer items in which a response may be entered directly from the keyboard or in which an expression, equation, or inequality may be entered using an on-screen character selector with mathematical symbols not found on the keyboard.

Drop-down: A list of possible responses is displayed when the response area is clicked with the mouse. These may occur more than once in a sentence or question.

Drag-and-drop: Words are moved around the screen by pointing at them with the mouse, holding the mouse button down, and then releasing the button when the element is positioned over an area on the screen. Such items are used for sorting, classifying, or ordering questions.

About 40 percent of the questions on the GED Science test focus on topics in the life sciences. Another 40 percent of the questions are on topics in the physical sciences. Twenty percent of the questions address topics in Earth and space science. Many questions require you to read and use your critical reasoning skills to interpret a document. That document might be text, a chart, a graph, a diagram, or a map.

Use this list as a guide for your studies. Be sure to study and practice each topic until you feel that you have mastered it.
