What should you know about the Science section of the TEAS 7?

The main goal of the science section of the TEAS 7 exam is to evaluate the test taker's scientific knowledge and competency. This section covers concepts related to human anatomy and physiology, biology, chemistry, and scientific reasoning.

What is the breakdown of the Science section of the TEAS 7?

The Science section of the ATI TEAS 7 exam presents a series of challenges to test your knowledge and analytical abilities within a 60-minute time frame. This section comprises 50 questions, with 44 scored and 6 unscored, aiming to evaluate your readiness to apply scientific concepts and reasoning. To succeed, it is essential to have a strong grasp of the four core areas covered: Human Anatomy & Physiology, Biology, Chemistry, and Scientific Method.

  • Human Anatomy & Physiology (18 questions) - This section delves into the fascinating realm of the human body, testing your knowledge of its intricate architecture and the interconnected dance of its various systems. Buckle up for questions that explore the following:
    • Understanding the Blueprint: Be prepared to demonstrate your grasp of basic anatomical terminology and the orientation of major body parts within the body's three planes (sagittal, coronal, and transverse).
    • A Deep Dive into Body Systems: This section will test your knowledge of the ten major systems that keep us alive and functioning. Be ready to answer questions related to the structure and function of the respiratory system, including inhalation, exhalation, and gas exchange. You'll also encounter questions on the cardiovascular system, exploring blood flow, heart function, and blood vessel anatomy. The digestive system's role in breaking down food and absorption of nutrients will be assessed. Don't forget the nervous system, the body's intricate communication network, and the muscular system, responsible for movement and posture. The reproductive system, integumentary system (skin, hair, nails), endocrine system (hormones), urinary system (waste removal), and immune system (defense against pathogens) will all be fair game.
  • Biology (9 questions) - This section broadens your focus to encompass the fundamental principles of life itself. Here's what you might encounter:
    • The Building Blocks of Life: Prepare to delve into the microscopic world of cells, the basic unit of life. Understanding cell structure, function, and organization will be key.
    • The Blueprint of Heredity: Explore the fascinating world of genetics, focusing on the role of DNA and RNA in carrying genetic information. Understanding Mendel's Laws of Inheritance, which govern the transmission of genetic traits from parents to offspring, will be valuable.
    • The Microscopic Culprits: Be prepared to answer questions related to the role of microorganisms in disease. Understanding how bacteria and viruses can cause illness and the body's defense mechanisms will be crucial.
    • The Powerhouse of Cells: Grasping the structure and function of basic macromolecules like carbohydrates, proteins, lipids, and nucleic acids is essential, as they play a vital role in cellular processes.
  • Chemistry (8 questions) - The chemistry section takes a closer look at the building blocks of matter and the intricate dance of chemical reactions. Here's what you might encounter:
    • The Fabric of Our Universe: Understanding the basic structure of atoms, including protons, neutrons, and electrons, and how they combine to form different elements is fundamental.
    • Physical Properties and Changes: Be prepared to answer questions regarding the properties of matter, including states of matter (solid, liquid, gas), and the physical changes matter can undergo (melting, boiling, freezing).
    • The Magic of Reactions: Chemical reactions, the processes by which substances interact to form new substances, will be explored. Understanding factors that influence reaction rates and how to predict the products of a reaction will be key.
    • Acids and Bases: The properties of acids and bases, including their impact on solutions, will be tested.
  • Scientific Method (9 questions) - This section assesses your comprehension of the scientific method, the cornerstone of scientific inquiry.  Here's what you'll need to be familiar with:
    • The Tools of the Trade: Demonstrate your proficiency in using basic scientific tools like microscopes, thermometers, and graduated cylinders.
    • Logic and Evidence: The ability to apply logic and evidence to form scientific explanations is crucial.
    • Predicting the Future: Scientific inquiry often involves predicting relationships between events, objects, and processes. Be prepared to demonstrate your ability to interpret data and make predictions based on observations.
    • Unraveling the Mysteries: This section assesses your ability to interpret scientific investigations conducted using the scientific method.

The Science section of the ATI TEAS 7 exam requires consistent practice and a strong foundation in all four of these core areas to succeed. Understanding the content and format of the exam is crucial for effective preparation.
