GED Science Test Topics
The science portion of the GED is designed to test individuals' knowledge of the following areas: earth and space science, physical science, and life science. Physical science topics include electricity, motion, and atoms. Life science topics range from genetics to the makeup of cells. Earth and space science topics revolve around weather patterns, natural resources, and the solar system.
Students will need to draw from their understanding of these topics to answer questions that fall under one of two main themes: human health and living systems or energy and related systems.
The first theme includes questions that cover components of the human body and other living organisms, how living organisms impact their environments, and how their environments affect them. The second theme includes questions that cover various energy sources and their uses, Earth's geochemical systems, and how energy is utilized within living organisms, including the human body.
Science Skills Tested on the GED
Questions on the science GED are also designed to test individuals' ability to apply these scientific concepts and understand scientific writing. Test takers are evaluated for their ability to apply math concepts and interpret statistical data as well. Examples of the tasks students might need to complete in order to demonstrate their skills in these areas are outlined below.
Reading and Writing in Science
Questions measuring individuals' ability to read scientific writing include ones that require them to read a paragraph and locate the evidence that validates the author's finding. Other questions test individuals' understanding of scientific vocabulary words contained in a passage.
Applying Scientific Concepts
Test takers are asked to apply their knowledge of scientific experiments to distinguish between the different types of variables and evaluate hypotheses. They might also be asked to make conclusions based on evidence presented in charts or graphs.
Applying Mathematical Reasoning in Science
Individuals are required to utilize their understanding of scientific formulas, probability, and statistics to answer questions. Test takers have the option of bringing their own calculator or utilizing the on-screen version available during testing. The on-screen calculator is the Texas Instruments TI-30XS Multiview.
GED Science Test Format
Test takers are allotted 90 minutes to complete the 34 questions on the science test, with no breaks during the testing session. Test takers must receive a score of 145 to pass.
The science test is comprised mainly of multiple-choice questions; however, there will be other types of questions on the exam. Test takers might be asked to select an answer from a drop-down menu, select areas on an image, and fill in the blank.
Physical science and life science topics each comprise 40% of the questions. The remaining 20% of the questions are related to Earth and space science.
