Study Guide

What the ATI TEAS Version 7 Science section actually covers

ATI's TEAS Version 7 organizes Science around three broad skill areas. Here's what each one tests and how to study for it.
1

Human Anatomy and Physiology

By far the largest share of the Science section. Expect questions on body systems and structures — like identifying joint types, tracing blood flow to and from organs, and distinguishing gray matter from white matter — at the level of a standard A&P course.

2

Life and Physical Sciences

Foundational biology (cells, genetics, ecosystems) and chemistry/physics concepts (states of matter, basic reactions, simple physics principles) that support the anatomy content.

3

Scientific Reasoning

Understanding the scientific method and experimental design — why a well-controlled experiment needs a control group and one isolated variable — plus the falsifiability principle: experiments can disprove, but never fully "prove," a hypothesis.

Sample ATI TEAS Version 7 Science questions with rationales

These are five real questions from our 94-question Science bank — the same format and difficulty you'll see on the TEAS Version 7 exam, with the correct answer and rationale shown.
Which of the following best describes the function of the epiglottis?
A. It produces digestive enzymes.
B. It prevents food from entering the trachea during swallowing.
C. It filters blood before it reaches the kidneys.
D. It regulates body temperature through sweat production.

Rationale: The epiglottis is a flap of cartilage that folds down over the trachea during swallowing, directing food into the esophagus instead of the airway.

The elbow is an example of which of the following types of joints?
A. Ball-and-socket
B. Pivot
C. Hinge
D. Saddle

Rationale: Hinge joints, such as the elbow and knee, allow movement in a single plane (flexion and extension), unlike ball-and-socket or pivot joints.

Which vessel carries oxygen-rich blood away from the heart to the rest of the body?
A. Vena cava
B. Pulmonary artery
C. Aorta
D. Pulmonary vein

Rationale: The aorta is the large artery that carries oxygenated blood from the left ventricle out to the systemic circulation. The pulmonary artery carries deoxygenated blood to the lungs, the pulmonary vein returns oxygenated blood to the heart, and the vena cava returns deoxygenated blood to the heart.

A researcher states, "No single experiment can prove a scientific theory true; it can only fail to disprove it." Which of the following best reflects this idea?
A. A theory that passes many tests becomes an absolute fact.
B. A theory remains provisionally accepted until evidence contradicts it.
C. A theory must be proven correct before it can be tested further.
D. A theory that cannot be tested is automatically considered false.

Rationale: This restates the falsifiability principle — scientific theories are never proven absolutely true, only provisionally accepted pending new evidence that might contradict them.

A researcher wants to test whether a new fertilizer increases plant growth. Which design best isolates the effect of the fertilizer?
A. Grow all plants with the fertilizer and measure their height after a month.
B. Grow half the plants with the fertilizer and half without it, keeping all other conditions the same.
C. Grow the plants in different amounts of sunlight and compare growth.
D. Survey gardeners about their experience using fertilizer.

Rationale: A controlled experiment isolates one variable (the fertilizer) by keeping all other conditions constant between a treatment group and a control group.

ATI TEAS Version 7 Science FAQ

1

How many questions are on the ATI TEAS Version 7 Science section?

ATI's TEAS Version 7 Science section is typically around 44 scored questions plus a handful of unscored pretest items, though the exact count and time limit can vary by test form — confirm the current details in your official ATI registration materials.

2

What score do I need on TEAS Science?

Nursing programs set their own minimum TEAS scores, and Science is scored as part of your overall Adjusted Individual Total Score. Ask your program what threshold they require.

3

Is this the same test as ATI's official TEAS Version 7 exam?

No. This is an independent, original study resource written to cover the same content areas and question style as ATI's TEAS Version 7 Science section. It is not affiliated with, endorsed by, or a reproduction of Assessment Technologies Institute's proprietary exam content.

4

How is this different from the practice assessments inside my ATI account?

Your ATI Testing account's official practice assessments should be your primary prep. This site is a free, unlimited supplement — one question at a time with an instant rationale, no login required.

5

What should I study first if I'm running out of time?

Prioritize Human Anatomy and Physiology — it's the largest sub-area by far, so mastering body systems (especially cardiovascular, musculoskeletal, and nervous system structures) covers the most ground per hour studied.
