What Kind Of Science Is on the GED?


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

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.
