GED Science Review

While many of us don’t don our lab coats and dabble with chemicals on a daily basis, science impacts our daily lives on a frequent basis. Much of the items and tasks we carry out everyday were created or perfected through the help of scientific knowledge. Your car wouldn’t run nearly as well without careful engineering and knowledge of physics and mechanics. Even preparing your dinner for the night counts as science, as you carefully blend the right amount of ingredients and spices, heat and other tools to create a tasty, edible result.


So, how does science does science apply to a high school curriculum and the professional world? In the broadest sense, science helps us to understand our world and how it works on a structural level. It develops our critical thinking, our ability to question what we know and why certain events unfold the way they do, and teaches us valuable evaluation skills. You may already be interested in entering the scientific field once you obtain your GED certification, whether its through earning a degree in the sciences or working directly for a company with scientific affiliations. Even if you are not, basic scientific knowledge is still important for you to have. If you are college-bound especially, you can expect to see science courses as part of your general education requirements, even if you don’t plan on majoring in any science-related disciplines.


With respect to the GED, the Science portion of the test is treated very generally. You will be tested on a variety of subjects, and will be expected to demonstrate adequate knowledge of all of them. Whether science is a favorite subject of yours or not, we are happy to help you by providing you with all the tools you’ll need to do well on the exam. We care about your success, which is why we have composed this extensive GED Science study guide. For further help, feel free to turn to other resources on our site, such as our GED Science flashcards and GED Science practice test. Though this guide, you’ll learn all you need about the exam—its formatting, what to expect from it, and what subjects you will need to brush up on as part of your studies.


What Is Featured on the GED Science Section?

The GED test’s Science section is composed of 50 questions total, all written in multiple choice format. You’ll receive a total of 80 minutes for this portion of the test, meaning you must budget your time wisely to do well.


As with every other subsection of the GED, the Science portion is meant to evaluate how well you understand the subject. Everything featured on the test fits within the curriculum commonly taught to today’s high school students. You won’t receive anything more advanced than what the average high school senior will have to learn. The creators of the GED have also taken into account which elements of science today’s adults rely upon most throughout their experiences in the workforce. You’ll find the following content areas being covered on the Science subsection: Earth and space science, physical science, and life science.


The questions presented to you on the test may unfold in any number of ways. Half of the questions you will find are accompanied by depictions of certain scientific scenes, about which you will be expected to answer questions about what is happening and why. Every question on the test will also align with at least one knowledge area of knowledge. You can also expect to find scientific texts on the test, about which you will answer questions about the events described, come up with solutions to scientific problems, and draw conclusions based upon the information presented.


We recommend that you study both the subjects listed on our GED Science study guide as well as the most elementary principles of science to familiarize yourself as much as possible prior to taking the exam. While your knowledge does not have to be anything approaching encyclopedic, you should have at least a rudimentary idea of each subject. To help you, we will go into further depth about each section.


Earth and Space Science

Space and Earth science encompass the disciplines of astronomy and geology, specifically. Questions about this subject will test your knowledge of Earth’s systems and structure, as well as the solar system, stars, and other important celestial bodies.


Physical Science

Physical science translates into the discipline of physics. Through this section you’ll demonstrate your knowledge of how motion works with relation to Earth’s gravitational pull. You will be expected to answer questions solving for certain determinable traits, such as speed and velocity. As such, Physical Science questions may involve some mathematical figuring on your part. Don’t worry too much about memorization for this section. You will always receive as much information as you need to answer the question as accurately as you can. Any formulas you need for your answer will be supplied to you.


Life Science

Life science relates specifically to biology and its related subjects. You will be expected to demonstrate how much you know about ecological systems on Earth and how living beings function and thrive within it. You may also have to answer a few questions about human biology, especially in accordance to one of two supplementary subjects also featured on the exam.


In addition to these three main materials, you may find questions relating to these two additional areas.


Energy and Related Systems

The ‘Energy and Related Systems’ portion of the exam applies to the properties of energy—the way various systems (both within the solar system and here on Earth) use energy, the ways in which energy changes based upon how it is being used, and where energy comes from. This subject will reflect in both Physical Science and Earth and Space Science questions.


Human Health and Living Systems

Questions under the ‘Human Health and Living Systems’ umbrella cover the complex relationship between humans and their environment. You will be expected to know about various biological subjects, such as hereditary properties, DNA, evolution, and how diseases form and evolve. You will also need a bit of anatomical knowledge, especially with relation to the human form and the various systems within it that help our bodies to function as they should.


While this guide isn’t entirely comprehensive, we hope it will be of help to you as you embark upon preparing for this important next step in your professional or academic career. To learn more about what you can expect to find on the exam, feel free to explore the links on this page or the rest of our site. We have ample information about each subject and subsection featured on the test. If you’d like some extra help preparing, we also have GED Science flashcards and a GED Science practice test available to you. With us, you’ll have all the tools necessary for your success.


Good luck and study hard!
