TEAS V Science Review

Making up almost a third of the test, the Science section of the TEAS V exam contains more questions than any of the other three sections, and is widely considered to be the most difficult portion of the exam. This sounds intimidating, and you should certainly work very hard at reviewing science topics before taking the TEAS, but the news isn’t all bad. The really great thing about the difficulty of TEAS Science is that the requirements for a “good” score on this portion of the test are much lower than on the others. In all three of the other sections, for example, test takers need to score at least 90% to reach the Exemplary level, but on Science, 81% or higher is considered Exemplary. In other words, if you prepare well for the TEAS Science sub-test, you’re likely to see a significant return on your study investment in a Science score that’s much higher than the average test taker achieved. To aid you even further, Mometrix offers TEAS Science practice questions that provide a preview of the type of questions you may experience on test day.

Science is the hardest section because nursing is a health care field, and science is the foundation of health care. Skills in English, reading, and math are vitally important, too, but scientific knowledge is the most critical part of a nurse’s skill set, and the TEAS test reflects that. Nurses need to know how all the organs and systems in the human body work, and how they work together, in order to be able to help patients recover from illnesses and accidents. They also need to have a firm grasp of the life and physical sciences, and how they affect life and health. When you sit down and take the TEAS V, you’ll need to be ready for all sorts of questions in any of these areas. Let’s take a more in depth look at what kind of questions you should expect to see on the TEAS.

What’s on the TEAS V Science Section?

You’ll be looking at about 50 questions, all multiple-choice, and you’ll have a little over an hour to answer them all. Questions in this section will fall into four categories: Earth and Physical Science, Life Science, Human Body Science, and Scientific Reasoning. You may have heard that the TEAS contains some questions that don’t count toward your score. That is correct – there are 20 questions on the exam that are being tested for use on future versions, and a wrong answer on one of these won’t affect your score. It’s quite possible that one or more of these questions will appear in the Science section, but you shouldn’t even take that into consideration. The experimental questions are not identified as such, and look just like the other questions, so there will be no way for you to know which questions count toward your score and which ones don’t. You should treat each question as if it counts, and do your very best to answer it correctly.

TEAS V Science: Human Body Science

To do well on these questions, you’ll need a good grasp of both anatomy and physiology. Many people are under the impression that these two terms mean pretty much the same thing. This is a misunderstanding. Although the two subjects are very closely related, and are often taught together as one course, they are by no means the same. Anatomy is the study of the structure of the different parts of the body, where they are located, and how they are connected. Physiology is the study of the functions of the different parts of the body, and how they work together. Expect some broad questions about general principles of anatomy and physiology. You will also see many questions about specific topics in anatomy and physiology, especially the various systems that keep the human body alive and healthy – the immune system, the circulatory system, the respiratory system, the digestive system, and the nervous system. This category will also include some questions about birth rates and death rates, and how they affect the population dynamics of a community.

TEAS V Science: Life Science

Many of the questions in this category of the TEAS Science section will test your knowledge of biology, one of the basic foundations of medical science. To do well on these questions, you’ll need to understand the concept of natural selection (evolution), and how the process of adaptation drives it. Having the basic system of biological classification memorized is a must (i.e., Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species). You’ll also need to be very familiar with the various parts of a cell and their functions. Expect to see questions about cellular organelles and their structure and function, and about the differentiation of cells. Can you explain respiration and photosynthesis and how they’re related, and compare and contrast them? You’ll need to be able to before taking the TEAS V. The same goes for mitosis and meiosis.

You should expect several questions about genes, RNA, and DNA, including a basic understanding of the structure of nucleic acids and their functions. The parts RNA and DNA play in cell replication will probably come up, too. You’ll need to know which kind of mutations can cause variations that show up in the next generation, as well as the part genes play in passing along traits. Mendel’s laws of genetics will almost certainly be covered, and you’ll need to know your way around the Punnett square. Can you explain the differences between genotypes and phenotypes? If not, you’ll need to work on that. You’ll also need to be able to explain RNA, DNA, proteins, genes, and chromosomes, as well as their similarities and differences.

TEAS V Science: Earth and Physical Science

For this category of the TEAS V Science section, questions will cover a wide range of topics, starting with properties of the very building blocks of matter, atoms, such as electrical charge and mass. You’ll be expected to understand that the major components of atoms are electrons, protons, and neutrons, and you’ll need to know their characteristics. The part that electrons play in chemical bonds is also very important. You’ll want to review acid/base reactions, and other chemical reactions, such as oxidation and reduction. Other topics you should brush up on include catalysts and their roles, what enzymes are and what they do, the pH scale and what it means, different kinds of energy (potential, kinetic, etc.), and how atoms and molecules differ in solids, gases, and liquids. In addition, you should be very familiar with the Periodic Table of Elements, and know why it’s arranged the way it is. By the way, just as with all of the other three categories, this is by no means an exhaustive list of every kind of question you might see, but it’s a solid foundation you should work on shoring up before reviewing other possible topics.

TEAS V Science: Scientific Reasoning

The questions in this category of the Science section aren’t testing the knowledge you’ve acquired and retained from your high school science classes. Instead, they’re used to determine your aptitude for science, or how skilled you are at using logic and reason to solve new problems you encounter and don’t know the answer to. This will be an important skill to have for anyone pursuing an education in nursing. You’ll need to understand how a scientific investigation works, including how to create and test a hypothesis, and how to use the results of an experiment to either revise the hypothesis, or form a conclusion. Of course, this will also require you to be able to compare different explanations for the results of the investigation, and to use logic, reason, and math to choose the one that is most likely to be correct. (By the way, this is the smallest category of questions on the TEAS V Science section.)

It should be clear now why Science is considered to be the hardest part of the TEAS V exam by the vast majority of people who have taken the test. It’s quite difficult, and you should thoroughly prepare for it. However, don’t let it overwhelm and discourage you. With proper preparation and review, you can get a good score.
