The science portion of the TEAS Exam covers basic scientific knowledge including:

-The human body

Scientific reasoning

The ability to reason scientifically is critical not only for success on the TEAS exam, but also for success in most college-level science courses.Students who can reason scientifically are able to apply the scientific method to problem solving, and they are able to understand and explain the results of scientific investigations. In addition, they are able to integrate information from multiple sources to draw conclusions about scientific phenomena.

The scientific reasoning section of the TEAS exam tests your ability to apply the scientific method to problem solving, and it also tests your ability to understand and explain the results of scientific investigations. In addition, you will be tested on your ability to integrate information from multiple sources to draw conclusions about scientific phenomena.

Here are some tips for how you can improve your scientific reasoning skills:

-Read scientific articles in popular magazines such as National Geographic, Discover, or Scientific American.
-Watch documentaries about science topics that interest you.
-Talk about science with friends or family members who are interested in science.
-Take a college-level science course.
-Practice solving problems using the scientific method.

The scientific method

The scientific method is a logical and analytical approach to problem solving. It begins with a question or problem and then uses observations, experiments and data to answer that question or solve the problem. The scientific method is important for the TEAS exam because it is a key component of scientific reasoning. To be successful on the science portion of the exam, you need to be familiar with the steps of the scientific method and be able to apply them to various science questions.

Biological processes

The science portion of the TEAS Exam covers four main topics: human Anatomy and Physiology; Biological Processes; Chemistry; and Earth Science.

Biological Processes includes questions on cell structure and function, metabolism, genetics, and evolution. You should be familiar with terms such as DNA, mRNA, mitosis, gene expression, transcription, translation, genetic drift, natural selection, and adaptation.

You should also be able to answer questions about the cell cycle, homeostasis, cell signaling, genetic disorders, and the structure and function of various body systems including the respiratory system, circulatory system, urinary system, Immune system , digestive system , endocrine system , and reproductive system .


If you’re planning to take the TEAS exam, you’ll need to make sure you’re prepared for the science portion. The science portion of the exam covers a variety of topics, including chemistry. Here’s a look at what you can expect to see on the chemistry section of the exam:

-Basic concepts: You’ll need to know basic concepts in chemistry, such as atoms, molecules, and chemical reactions.
-The periodic table: You should be familiar with the elements on the periodic table and their properties.
-Measurement: You’ll need to know how to measure various properties of substances, including mass, volume, density, and temperature.
-Stoichiometry: You’ll need to be able to calculate the ratios of reactants and products in chemical reactions.
-Chemical equations: You should be able to write and balanced chemical equations.
-Acids and bases: You’ll need to understand acids, bases, and pH levels.
-Reactions in solution: You should know about how substances interact in solution, including precipitation reactions and acid-base reactions.


The physics portion of the TEAS exam covers topics including force, motion, energy, waves and sound, electricity and magnetism, and light. You should expect to answer questions on how these concepts apply to real-world scenarios. To prepare for this section of the exam, brush up on your knowledge of the following topics:

-Newton’s laws of motion
-Force and acceleration
-Work, power and energy
-Properties of waves
-Sound waves
-Electricity and magnetism
-Light waves

Earth and space science

Earth and space science is a very important subject to study for the TEAS exam. This section of the test covers topics such as the solar system, Earth’s resources, ecosystems, and weather patterns. Here are some specific things you should know for this section of the exam:

-The solar system: The solar system is made up of the sun, planets, moons, asteroids, comets, and meteoroids.
-The sun: The sun is a star that is located in the Milky Way galaxy. It is about 150,000 times the size of Earth and has the mass of about 333,000 Earths.
-The planets: There are eight planets in the solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
-Moons: A moon is a natural satellite that orbits a planet. There are over 170 moons in the solar system.
-Asteroids: Asteroids are small rocky bodies that orbit the sun. There are millions of asteroids in the solar system.
-Comets: Comets are small icy bodies that orbit the sun. They are made up of dust and ice and often have a tail of gas and dust particles that points away from the sun.
-Meteoroids: Meteoroids are small pieces of rock or metal that orbit the sun. They range in size from tiny dust particles to large boulders.

Scientific history and research

Though you may not realize it, scientific history and research play a large role in the material covered by the science section of the TEATS exam. A large portion of the questions on the test will be based on scientific experiments and theories that have been proven over time. As such, it is important that you familiarize yourself with the most important experiments and theories in order to do well on the test.

In addition to knowing the history behind various scientific concepts, you will also need to be able to understand and apply the principles of scientific research. This includes understanding things like the scientific method and how to interpret data from experiments. If you can master these skills, you will be well on your way to acing the science portion of the TEAS exam.

The impact of science on society

Science has always been a part of human society. From early attempts to understand the world around us, to the development of complex theories and models, science has played a central role in shaping our understanding of the universe.

In recent years, the impact of science on society has become increasingly apparent. With the advent of new technologies, we are now able to harness the power of science like never before. From medical breakthroughs to advances in communications and transportation, science is making a positive impact on the world around us.

As we enter a new era of scientific discovery, it is important to remember the impact that science has on society. The decisions we make today will have a profound effect on the world we live in tomorrow.

Careers in science

There are many careers in science, including but not limited to: biology, chemistry, Earth science, physics, and medicine. STEM (science, technology, engineering, and mathematics) careers are some of the fastest growing in the United States. According to the U.S. Department of Labor, “Employment of computer and information technology occupations is projected to grow 12 percent from 2019 to 2029, much faster than the average for all occupations. These occupations are expected to add about 546,200 new jobs. Demand for these workers will stem from greater emphasis on cloud computing, the collection and storage of big data, and information security.”
