This chapter provides sample Science test questions, including two Short Answer items, to help you prepare for taking that section of the GED test.
Record your answers directly in this book or on a separate sheet of paper, if you think you’ll want to revisit these practice questions at a later date. Mark only one answer for each item, unless otherwise indicated. And be sure to have an extra sheet of paper handy, or use your computer’s word processor, to practice preparing and writing the Short Answer items. At the end of the chapter, we provide detailed answer explanations for you to check your answers.
Remember, this is just preliminary practice. We want you to get used to answering different types of Science test questions. Use the complete practice tests in Parts VI and VII to time your work and replicate the real test-taking experience.
The Science test consists of a series of items intended to measure general concepts in science. The items are based on short readings that may include a graph, chart, or figure.

Work carefully, but don’t spend too much time on any one question. Be sure you answer every question.
