Do you want to ace your GED Science exam? Do you require effective exam preparation? As a result, this GED Science Study Guide 2024 is ideal for you! Get-TestPrep will go over what a GED Science Test is and what it entails. Then we’ll go over frequently asked questions about the Science Test, as well as some study tips and tricks to help you ace your exam!
What Is The GED Test?
The General Educational Development (GED) examination is a series of exams that test takers must complete in order to get a GED diploma (also known as a GED certificate). This certificate is equivalent to a standard high school diploma.
The GED Test, or General Educational Development Test, consists of four assessments. These examinations are intended to assess your performance in conventional high-school courses for anybody 16 and older who is not enrolled in high school. Rather than assessing your recall of specific facts, dates, or terminology, the GED Test asks you to demonstrate applicable knowledge and abilities connected to specific circumstances.
Individuals may be interested in obtaining a GED certificate since most employers need a high school diploma or the equivalent. Adults who did not complete high school can fulfill this criterion by completing the GED exam.
What’s On The GED Science Test?
The GED Science test consists of 50 questions in total, most of which are written in multiple-choice format. You will be given a total of 80 minutes for this section of the test, so you must plan your time wisely if you want to do well.
Like other GED exams, to get a passing score, you have to achieve a 145 or higher score. Questions are formatted in variety, multiple-choice, drop-down, and short answers are examples.
Due to so many areas of science, focusing on understanding science texts, tables, charts, and graphs; how science experiments and studies are designed; and scientific theories or processes. In addition, you should practice concluding data and evaluating other people’s conclusions. Moreover, comparing and evaluating multiple conclusions, sets of data, or theories.
Earth and Space Science
Astronomy and geology are two special disciplines that come under space and Earth science. This subject’s questions will test your knowledge of Earth’s systems and structure, as well as the solar system, stars, and other important celestial bodies.
Physical science translates into the discipline of physics. You will demonstrate your knowledge of how motion works in relation to the gravitational pull of the Earth in this section. You will be asked to answer questions on determinable traits such as speed and velocity. As a result, Physical Science questions may require some mathematical calculation on this part.
Life science is in line with biology and its related subjects. You will be required to demonstrate your knowledge of Earth’s ecological systems and how living beings function and thrive within them. You may also be required to answer a few questions regarding human biology, particularly in relation to one of two supplementary subjects included in the test.
Energy and Related Systems
The ‘Energy and Related Systems’ section of the test covers the properties of energy, such as how various systems (both within the solar system and on Earth) use energy, how energy varies depending on how it is used, and where energy comes from. This subject will be reflected in questions in both Physical Science and Earth and Space Science.
Human Health and Living Systems
Questions under the ‘Human Health and Living Systems’ umbrella address the complex relationship that exists between humans and their environment. You will be required to understand a variety of biological subjects, including hereditary properties, DNA, evolution, and how illnesses develop and evolve. You’ll also need some anatomical knowledge, particularly about the human form and the various systems inside it that help our bodies function properly.
What Types Of Questions Are On The GED Test?
On the GED Science Test, there is a lot of confusion about short answers and lengthier responses. In 2012, the revised GED test featured an Extended Response essay in social studies and short answer questions in science. The scientific exam never included a full essay, known as an extended answer. The extended answer essay was removed from the GED social studies test in March 2016. There is only one extended response essay on the current GED test, and it is on the language arts test.
How about the science exam? According to certain reports, there are no longer any quick-answer questions… Because the essay was pulled from social studies, there may be some misunderstanding. The following scientific question types are listed in the 2018 GED Technical Manual:
- Multiple Choice. The majority of the questions are multiple-choice! If you study using multiple-choice questions, you should be OK. There are four answer options for multiple choice questions.
- Drop-Down: Drop-down questions will prompt you to select an item to complete a phrase or an equation. After multiple choice, this should be the most prevalent sort of question.
- Drag-and-Drop: This type of question will ask you to drag an item to its correct place, maybe in a diagram, an equation, or a matching exercise.
- Fill-in-the-Blank: You may be asked to complete a statement or an equation in these questions.
- Hot Spot: A hot spot inquiry requires you to select the right answer from a picture. For instance, you may need to click on a section of a diagram.
- Short Answer: The short answer is still included for a question type that you may encounter. Because this is not a long response, it is not as serious as a complete essay question. A brief response question may request that you summarize what you read, form a hypothesis, reach a conclusion, or offer evidence from what you read. But don’t get too worked up over it. If you have a short answer question on your version of the test, attempt to write the best response you can. Take no more than ten minutes, but don’t leave it blank. Simply respond to the question in a paragraph using whole sentences. Don’t write any more than is necessary to answer the question.

What Is Mercury Like?
Mercury has virtually no atmosphere. It may get incredibly hot since it is so near to the sun. Mercury, for example, can reach a searing 800 degrees Fahrenheit on its sunny side. (However, Mercury is not the hottest planet in the solar system; Venus is.) Mercury’s dark side is that it gets exceedingly cold since it has practically no atmosphere to keep heat in and the surface heated. The temperature can fall below -300 degrees Fahrenheit. The sunlight never reaches the bottoms of several craters near Mercury’s poles, suggesting that ice may exist inside those craters, where it would be always frozen.
How Has NASA Studied Mercury?
Mercury is challenging to observe from Earth due to its near proximity to the sun. Although no humans have ever visited Mercury, Mariner 10 was the first robotic spacecraft to do so. Mercury flew it in 1974 and 1975. Mariner 10 was only able to photograph around half of Mercury’s surface. No spacecraft reached Mercury for more than 30 years after Mariner 10. Then, in 2008 and 2009, NASA’s MESSENGER spacecraft sailed by Mercury. It began its orbit around Mercury on March 17, 2011. MESSENGER will map Mercury by photographing the planet’s surface, including previously unseen locations. It will also collect data on the composition of the surface rocks, as well as measure mountain heights and crater and valley depths. Scientists will be able to learn more about Mercury’s interior thanks to data obtained by MESSENGER. MESSENGER will teach people more about Mercury than they have ever known before.
According to the article, which fact concerning Mercury do scientists NOT know?
- Whether asteroids or other cosmic objects have collided with Mercury’s surface
- Mercury’s atmosphere and its impact on its temperature
- The structure of Mercury’s core
- The temperature range on Mercury’s surface

GED Science Tips and Tricks
If you’re not used to reading about science and looking at data, the GED Science Test can be difficult. The best method for practicing GED Science is to find a science program that is suitable for each person. Applying a variety of science skills is more effective than learning details about life science, physical science, or Earth and space science. We will give some tips to get you started in the following.
Study Reading and Math
You have to apply both reading and math in Science tests. Having a good background in GED reading and math first will help you with many areas of the GED Science Test such as reading charts and graphs and interpreting data, using formulas, understanding evidence and logic, reading science texts, and understanding new vocabulary and reading and math are foundational skills for science. It’s best to have a good foundation first!
Take the GED Science Practice Test
The best method to begin practicing for the GED science test is taking a practice test. It not only gives you experience with the types of questions but also tells you what topics and how much you have to meet in a real test. You can take our free GED practice test 2024 for all GED topics on our website. Let’s start!
Study More Quickly and Effectively
Indeed, you have to understand some science for the science test. Some parts of the test are reading and math (in particular is data), so how to get the science knowledge you need in the best way:
First, pay attention to scientific theories, formulas, how studies are designed, and how experiments were done. That will gradually give you the background for reading about science topics and texts.
Second, you should make and organize your own notes. The more you organize and revise notes in your own words, the better you’ll get information. Besides, you should also make your own diagrams of scientific processes and make your own outlines of the texts that you can read easily.
Third, you should make sure that you understand the vocabulary because the science test has a lot of unfamiliar words and phrases. So you have to study prefixes, suffixes, and roots that can help you take the test quickly. In addition, you can make flashcards or a vocabulary in your own words.
Last but not least, you must study every day preferably. You should learn a little bit every day better than studying for a large chunk once a week. You’ll remember the ideas better if you study before you go to sleep.
Learn Some GED Science Formulas
There are some helpful formulas and equations to be familiar with for the GED science test. You’ll need to work with data, like finding the mean, median, or range competently. Memorizing physics formulas is not obligatory, but it is useful to be familiar with the physics concepts. Besides, you also need to know how to use formulas to find unknown values.
- Distance Travelled distance = rate × time
- Velocity (Speed) velocity = change in distance ÷ change in time
- Acceleration = change in velocity ÷ change in time
- Momentum momentum = mass × velocity
- Weight = mass × gravity
Learn about Science Studies and Experiments
Getting familiar with the ideas in scientific studies and experiments is a good method to improve your score.
Read the Text, Examine the Graphics
In the GED Science Test, the science text is about applying your skills to the text and graphics on the text. The key to the answer is in the text and graphics most of the time. So let’s try the following strategies:
- First, read the question, and find the keywords you need to.
- Carefully read the text or examine the graphic and look for the relevant information to answer the questions.
- Before reading the text, read through the answer choices and find out the one that best reflects what you read about in the text or data.
- Go back to the text to check if you’re not sure.
Use Good Test-Taking Skills
First, you can remove wrong answers. If you’re not sure of an answer, eliminate all the wrong answers first then pick the last correct answer.
In addition, it is good if you have a system for guessing. It’s essential to select the answer to every question. If you have a system for whenever you need to guess, such as always selecting the first answer that you can’t eliminate, you will have better results than your intuition.
It’s very important to answer every question. If there is a short answer question, let’s attempt your best to write an answer. If there is a fill-in-the-blank, write something even if it is just a guess. Answer all multiple-choice questions. For guessing, you will never lose points.
The science test consists of many processes and physical structures. So attempt to make your own diagrams to know some important areas of science easily. You could make your diagrams to show or explain:
- Cell Structure
- The Water Cycle
- The Carbon Cycle
- The Structure of Planet Earth
- The Solar System
- Ecosystems (Energy Pyramid, Food Web, Food Chain)
- The Nitrogen Cycle
- The Oxygen Cycle
Learn Your Elements
In the GED Science test, the symbols can be unfamiliar. You will almost certainly come across symbols for elements or molecules in the text. Study what the symbols for common elements and molecules are and what those symbols imply.
Focus on Evidence and Data
Evidence and data are a vital part of the GED Science Test. You should be able to:
- Read, interpret, and from charts, graphs, and tables of data draw conclusions
- Compare ideas or sets of data and understand how they’re related
- Check whether the data supports an idea or hypothesis
- In charts, graphs, and tables, find out trends and relationships in the data
What Do You Need for GED Test Day?
To be successful on exam day, you must prepare the night before by eating well and sleeping sufficiently. It may be beneficial to get up early on the day of the exam, do something physical to get yourself in the appropriate frame of mind and go through your notes.
- A government-issued picture ID
- A TI-30XS portable calculator
- A calculator reference sheet
On the day of the test, make sure you perform the following:
- Eat before the exam because you won’t be able to once it begins.
- Consider going for a run, performing yoga, or meditating to settle your anxieties.
- Go through your notes again.
- Examine your materials and double-check the exam time.
Keep in mind that you need to check into the testing center at least 15 minutes early. Avoid drinking alcohol the night before and get plenty of rest. If you’re more than 15 minutes late, you might not get to take the test.
