Sample PAU General Sciences (Cantabria) Practice Questions

Try these sample questions to review concepts for the PAU General Sciences (Cantabria) exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which sequence best represents the standard steps of the scientific method used in scientific investigation?
A.Observation, hypothesis formulation, experimentation, data analysis, and conclusion
B.Conclusion, hypothesis formulation, observation, experimentation, and data analysis
C.Experimentation, observation, conclusion, hypothesis formulation, and data analysis
D.Hypothesis formulation, conclusion, observation, data analysis, and experimentation
Explanation: The scientific method begins with observing a phenomenon, then formulating a testable hypothesis to explain it, designing and running experiments, analyzing the resulting data, and finally drawing a conclusion that either supports or refutes the hypothesis.
2A student wants to test how the amount of fertilizer applied affects plant height. In this experiment, plant height is the:
A.Independent variable
B.Dependent variable
C.Controlled variable
D.Confounding variable
Explanation: Plant height is the dependent variable because it is the outcome that is measured and that changes in response to the amount of fertilizer, which the researcher deliberately varies.
3What is the main purpose of including a control group in a scientific experiment?
A.To increase the total number of participants so the study appears more credible
B.To ensure that every participant receives the experimental treatment
C.To provide a baseline for comparison so the effect of the tested variable can be isolated
D.To eliminate the need for statistical analysis of the results
Explanation: A control group does not receive the experimental treatment and serves as a baseline, allowing researchers to attribute observed differences to the independent variable rather than to chance or other factors.
4In the International System of Units (SI), which unit is the standard base unit for measuring mass?
A.Gram
B.Pound
C.Newton
D.Kilogram
Explanation: The kilogram (kg) is the SI base unit of mass, while the gram is a smaller, derived unit (one-thousandth of a kilogram) commonly used for everyday measurements.
5A measurement is reported as 4.20 cm. How many significant figures does this value have?
A.Three
B.One
C.Two
D.Four
Explanation: In 4.20, the digits 4, 2, and the trailing zero after the decimal point are all significant, giving three significant figures; a trailing zero after a decimal point is always counted as significant because it indicates measurement precision.
6If a corrosive chemical accidentally splashes into a student's eye during a laboratory activity, what is the correct immediate first response?
A.Rub the eye vigorously to remove the chemical
B.Flush the eye continuously with water at an eyewash station for several minutes
C.Apply a neutralizing chemical directly to the eye
D.Wait to see if irritation develops before taking any action
Explanation: Standard laboratory safety protocol requires immediately flushing the affected eye with copious amounts of water at an eyewash station for at least 15 minutes to dilute and remove the chemical before seeking medical attention.
7According to Karl Popper's criterion for distinguishing science from pseudoscience, a genuinely scientific statement must be:
A.Universally accepted by every scientist working in the field
B.Impossible to test using any current or future technology
C.Falsifiable, meaning it can in principle be proven false by an observation or experiment
D.Derived solely from mathematical logic without any empirical component
Explanation: Popper argued that what separates science from pseudoscience is falsifiability: a scientific claim must make predictions specific enough that they could be shown wrong by evidence, even if they are not ultimately falsified.
8A study finds that ice cream sales and drowning incidents both rise during the summer months. What does this best illustrate?
A.Ice cream consumption directly causes drowning
B.Drowning incidents directly cause increased ice cream sales
C.The study proves a scientific law linking the two variables
D.Correlation between two variables does not necessarily imply a causal relationship
Explanation: Both ice cream sales and drownings increase because of a third, confounding variable — warmer weather leads to more swimming and more ice cream purchases — illustrating that correlation alone does not establish that one variable causes the other.
9What role does peer review play in the scientific publication process?
A.It allows independent experts to evaluate a study's methodology and evidence before publication
B.It guarantees that the published results are permanently true and beyond future revision
C.It grants the researchers a patent on their discovery
D.It automatically ensures the study will be replicated by other laboratories
Explanation: Peer review is a quality-control process in which independent specialists assess a manuscript's methods, data analysis, and conclusions for soundness and originality before it is accepted for publication in a scientific journal.
10Why are double-blind designs frequently used in clinical drug trials?
A.To administer double the standard dosage to all participants
B.To prevent both participants and researchers from knowing who receives the treatment or placebo, reducing bias
C.To allow researchers to change the treatment protocol partway through the trial
D.To ensure that every participant receives the active drug rather than a placebo
Explanation: In a double-blind trial, neither participants nor the researchers assessing outcomes know who is receiving the active treatment versus a placebo, which prevents expectation effects from influencing the reported results.

About the PAU General Sciences (Cantabria) Exam

Comprehensive 100-question practice test bank for the Cantabria (Universidad de Cantabria / UNICAN) PAU exam in General Sciences (Ciencias Generales). Ciencias Generales is the compulsory modality subject introduced for the Bachillerato General track by Real Decreto 243/2022 (LOMLOE), assessing scientific methodology alongside matter and energy, the Earth system, 21st-century biology, and forces and motion, drawn from the official saberes básicos as applied by UNICAN.

PAU General Sciences (Cantabria): Suggested Study Strategy

1Build a one-page glossary of scientific-method terms — independent/dependent/controlled variables, control group, systematic vs. random error, falsifiability, p-value, extrapolation vs. interpolation — since these concepts are woven into tasks across every content block, not just tested in isolation.
2Master the matter-and-energy toolkit: SI units, atomic structure and periodic trends, ionic/covalent/metallic bonding, chemical nomenclature, balancing equations and stoichiometry, and the first law of thermodynamics.
3Review Earth-system fundamentals together: Earth's internal layers, plate boundary types, the rock cycle, the water and carbon cycles, the greenhouse effect versus ozone-layer depletion, and evidence for climate change.
4Learn the core biotechnology vocabulary from the Biología para el Siglo XXI block: PCR, restriction enzymes, molecular cloning, and CRISPR-Cas9, plus how vaccines, monoclonal antibodies, and antibiotic resistance work.
5Practice the standard physics formulas for the forces-and-motion block — Newton's three laws (F = ma), kinematic equations for uniformly accelerated motion, torque balance, momentum conservation, and E = mc² — since numerical problems recur across past papers.

Frequently Asked Questions

Is this practice bank in the same format as the real Cantabria PAU exam?

No, and it is important to know the difference. The official Cantabria PAU paper for Ciencias Generales is a 90-minute exam sat in Spanish and organized into four compulsory sections (apartados), each worth 2.5 of the 10 total points. Within most sections, candidates choose one of two open-response tasks to complete, and the questions require written, justified answers rather than a selection from a list of choices. This bank is an English-language multiple-choice study adaptation of the official 2º Bachillerato theory syllabus (scientific methodology, matter and energy, the Earth system, 21st-century biology, and forces and motion) — not an official translation, not a past paper, and not a simulation of the exam format. Use it to drill the underlying knowledge quickly, then practice writing full, justified responses to open-ended prompts separately, because that is what the examiners actually mark.

What is the official subject title for this PAU exam in Cantabria, and where does it come from?

The official subject title is Ciencias Generales, a 2º Bachillerato subject introduced nationally by Real Decreto 243/2022 (LOMLOE), which created a fourth Bachillerato modality — the Bachillerato General — alongside Ciencias y Tecnología, Humanidades y Ciencias Sociales, and Artes. Under this decree, students in the General modality take Ciencias Generales plus two further elective modality subjects, and Ciencias Generales is examined as their PAU modality paper by the University of Cantabria (UNICAN) PAU Organising Commission.

Which students take Ciencias Generales, and how does it relate to Matemáticas II or Latín II?

Ciencias Generales is the compulsory modality-specific exam for students who followed the Bachillerato General track, taken during the mandatory Access Phase (Fase General) of the Cantabria PAU — the same phase and, on the official 2026 timetable, the same exam slot in which Ciencias-track students sit Matemáticas II, Humanidades-track students sit Latín II, and Ciencias Sociales-track students sit Matemáticas Aplicadas a las Ciencias Sociales II. Each Bachillerato track sits only its own assigned modality subject, not all of them.

How is the final PAU mark calculated for university admission in Spain?

The Access Phase admission grade combines Bachillerato GPA (60%) and the PAU Access Phase mark (40%, made up of Lengua Castellana y Literatura, Historia, a foreign language, and the modality subject — Ciencias Generales for General-track students). An overall mark of at least 5.0 is required to pass, and candidates can then sit up to four additional Admission Phase (voluntary) subjects to add up to 4 extra points toward specific degree programs.

What content blocks are tested on the Cantabria Ciencias Generales exam?

The official saberes básicos are organized into five blocks: Construyendo Ciencia (scientific methodology), Un Universo de Materia y Energía (matter and energy), El Sistema Tierra (the Earth system), Biología para el Siglo XXI (21st-century biology), and Las Fuerzas que Rigen el Universo y las Fuerzas que Nos Mueven (forces and motion). The written exam scores four sections corresponding to the matter-and-energy, Earth-system, biology, and forces blocks, while scientific-methodology skills are assessed as a transversal thread running through the tasks in those sections.

In what language is the Cantabria PAU examination offered?

In Cantabria, official PAU examination papers are provided in Spanish.

When is the Cantabria PAU 2026 Ciencias Generales exam scheduled?

The 2026 ordinary convocation runs June 2–4, with Ciencias Generales scheduled on the first exam day alongside the other modality-subject papers (including Matemáticas II). The extraordinary convocation runs June 30–July 2, 2026. Exact session times are published each year by the University of Cantabria PAU Organising Commission.
