, TEAS 7 Science Practice Test 2026: 90 Questions & Answers
1. After identifying a problem, asking questions, developing a hypothesis, and collecting
experimental data, what is the immediate next step in the scientific method?
A. Observe the data.
B. Analyze the results.
C. Measure the data.
D. Develop a conclusion.
Answer: B
Explanation: The scientific method consists of six core steps. After data is collected, it must be
examined and interpreted before a final conclusion can be drawn. Analyzing the results is the
essential step that comes after experimentation and before forming a conclusion.
2. Which statement about qualitative and quantitative data is NOT accurate?
A. Quantitative data is gathered through numerical measurements.
B. Qualitative data is centered on perspectives and observed behaviors.
C. Qualitative data is acquired through observations and interviews.
D. Quantitative data is inherently more scientifically valid than qualitative data.
Answer: D
Explanation: Both qualitative and quantitative data are crucial in scientific research and serve
different purposes. Quantitative data deals with numerical measurements, while qualitative data
describes qualities or characteristics. One type is not inherently "better" or "more accurate" than
the other; their value depends on the research question.
3. A chart displays monthly snowfall and the number of sunny days in a specific location from
November to April. Based solely on the chart's data, which conclusion is most directly
supported?
A. The months with the highest snowfall also show the fewest sunny days.
B. Heavy snowfall actively blocks sunlight, causing fewer sunny days.
C. April is an unsuitable month for skiing in that region.
D. There is no correlation between snowfall amounts and sunny days.
Answer: A
Explanation: The chart presents two measurable variables: snowfall and sunny days. A valid
, conclusion must be based on the direct relationship shown between these two data sets, without
introducing external assumptions about causality.
4. Which statement correctly pairs a physiological structure with its function?
A. The trachea connects the throat to the stomach and uses contractions to move food.
B. The esophagus is the main airway that links the larynx to the lungs.
C. The diaphragm is a muscle that expands the thoracic cavity upon contraction, facilitating
inspiration.
D. The epiglottis seals the esophagus during swallowing to prevent food from entering the
stomach.
Answer: C
Explanation: The diaphragm is a major muscle of respiration. When it contracts, it flattens and
moves downward, increasing the volume of the thoracic cavity and drawing air into the lungs
(inspiration).
5. Where in the body would you find cartilage fulfilling its cushioning function?
A. As the dense connective tissue composing the majority of the skeletal system.
B. As supportive pads located between the vertebrae of the spine.
C. As fibrous collagen structures connecting muscles to bones, like the Achilles tendon.
D. As a fatty layer beneath the skin that provides insulation and protection.
Answer: B
Explanation: Cartilage is a resilient connective tissue that cushions joints. The intervertebral
discs between the spinal vertebrae are composed of fibrocartilage, which acts as a shock
absorber.
6. What are the two primary criteria for classifying epithelial tissue?
A. Cell type and cell function
B. Cell shape and cell type
C. Cell layers and cell shape
D. Cell function and cell layers
Answer: C
Explanation: Epithelial tissue is classified based on the number of cell layers (simple, stratified,
pseudostratified) and the shape of the cells at the surface (squamous, cuboidal, columnar).
