Themenquiz 1: The Science test and the nature of science

  1. Frage 1 von 17

    How many questions are on the CAEC Science test?
    Antwort anzeigen

    Antwort: D. 35

    The CAEC Science test has 35 questions.

  2. Frage 2 von 17

    How much time do you have to write the CAEC Science test?
    Antwort anzeigen

    Antwort: B. 90 minutes

    You have 90 minutes for the 35 Science questions.

  3. Frage 3 von 17

    Which strand makes up the largest share of the CAEC Science test?
    Antwort anzeigen

    Antwort: D. Scientific inquiry skills

    Scientific inquiry skills make up 60–85% of the test, far more than the other two strands.

  4. Frage 4 von 17

    What score do you need to pass the CAEC Science test?
    Antwort anzeigen

    Antwort: C. 55%

    Every CAEC test, including Science, needs at least 55% to meet the minimum standard.

  5. Frage 5 von 17

    A student writes: "The water in the beaker is bubbling." What kind of statement is this?
    Antwort anzeigen

    Antwort: A. An observation

    It describes only what the student can see. An observation uses the senses or a tool and adds no explanation.

  6. Frage 6 von 17

    A student writes: "The tomato plant's leaves are yellow, so it probably needs more nitrogen." Which part is an inference?
    Antwort anzeigen

    Antwort: D. It probably needs more nitrogen

    An inference is an explanation based on what you observed. Yellow leaves are seen; the lack of nitrogen is a guess about why.

  7. Frage 7 von 17

    Which question can be answered by a scientific investigation?
    Antwort anzeigen

    Antwort: D. Does a bike tire lose air faster in cold weather?

    A testable question can be answered by measuring something. Moral, beauty and supernatural questions cannot be tested with evidence.

  8. Frage 8 von 17

    Why is "Should cities ban gas-powered leaf blowers?" NOT a question science alone can answer?
    Antwort anzeigen

    Antwort: D. It asks what people should do, which depends on values

    Science can measure noise or pollution, but deciding what we should do is an ethical or social choice that also depends on values.

  9. Frage 9 von 17

    Doctors once thought most stomach ulcers were caused mainly by stress and lifestyle. Later studies found that a bacterium was often the cause. What does this show about science?
    Antwort anzeigen

    Antwort: C. Ideas can change when new evidence is found

    Science is ongoing inquiry. Ideas are kept, changed or replaced when new evidence appears.

  10. Frage 10 von 17

    In a study of a new cough medicine, one group takes the medicine and another takes a sugar pill that looks the same. What is the sugar pill called?
    Antwort anzeigen

    Antwort: D. A placebo

    A placebo looks like the real treatment but has no active ingredient. It shows how much people improve just from being treated.

  11. Frage 11 von 17

    In a double-blind study, who knows which people are getting the real treatment during the study?
    Antwort anzeigen

    Antwort: A. Neither the participants nor the researchers who work with them

    In a double-blind study, both groups are kept unaware, so expectations cannot affect the results or how they are recorded.

  12. Frage 12 von 17

    Why do researchers try to use a large, randomly chosen sample?
    Antwort anzeigen

    Antwort: A. Results are less likely to come from chance or one unusual group

    A large random sample better represents the whole population, which makes the results more reliable.

  13. Frage 13 von 17

    What happens during peer review?
    Antwort anzeigen

    Antwort: C. Other experts check a study before it is published

    Peer review is a check by independent experts in the same field. It helps keep research credible.

  14. Frage 14 von 17

    A lab in Winnipeg reports a surprising result. Labs in Halifax and Vancouver repeat the experiment and get the same result. Why does this matter?
    Antwort anzeigen

    Antwort: A. Replication makes the result more trustworthy

    Replication means other scientists can repeat a study and get similar results. It increases confidence in the finding.

  15. Frage 15 von 17

    A study saying an energy drink improves memory was paid for by the company that sells the drink. What possible problem should a reader notice?
    Antwort anzeigen

    Antwort: D. Bias from interest-group funding

    When a group that benefits from a result pays for the study, there is a risk of bias. Readers should look for independent studies.

  16. Frage 16 von 17

    A company ran six trials of its new fertilizer. Two showed better growth and four showed no change. Its ad mentions only the two good trials. What kind of bias is this?
    Antwort anzeigen

    Antwort: D. Selective reporting

    Selective reporting means sharing only the results that support what you want and leaving out the rest.

  17. Frage 17 von 17

    A researcher strongly believes a new teaching method works. She grades the tests herself and knows which students used the method. What is the best way to limit bias?
    Antwort anzeigen

    Antwort: B. Have a grader who does not know the groups mark the tests

    A researcher's own beliefs can affect judgement. Blind grading removes the chance that her expectations shape the scores.

Was Sie vor der Prüfung wissen sollten

  • The CAEC replaced the GED® in 2024. Completed GED® credentials stay valid.
  • There are five CAEC tests: Reading, Writing, Mathematics, Science and Social Studies. Your credential is issued when you pass all five and/or meet PLAR requirements.
  • The Science test has 35 questions in 90 minutes.
  • The Science test has three strands: nature of science (10–25%), scientific inquiry skills (60–85%), and science, technology, society and environment (5–15%).
  • Most Science questions (50–80%) are of moderate complexity: applying concepts, choosing an approach or selecting tools, rather than simple recall.
  • You need 55% to pass. 80–100% is "exceeds minimum standard" and 55–79% is "meets minimum standard".
  • Calculators may be used only on Part II of the Mathematics test. Dictionaries, thesauruses and translators are not permitted on the Science test.
  • You may write a subject test once per calendar month and up to 3 times per calendar year. A sample test is available in each subject on the CAEC digital platform.

Häufig gestellte Fragen

Is this the official CAEC Science test?

No. This is an independent practice course. It is not run by the CAEC Testing Service or any province or territory, and your scores here are not CAEC results.

What does the certificate from this course show?

The certificate of completion shows that you finished this practice course and scored at least 80% on its final assessment. It is not the CAEC, not a high school equivalency and not an official result, so schools and employers will not accept it in place of the CAEC.

Do I need to memorize a lot of science facts?

Less than you might think. Most of the test (60–85%) is scientific inquiry skills, such as finding variables, reading tables and graphs and judging conclusions. Practise those skills with the scenarios in this course.

Can I use a calculator on the Science test?

The CAEC Test Administration Guide allows calculators only on Part II of the Mathematics test. Practise simple arithmetic, such as averages, differences and unit conversions, by hand.

Why is the pass mark 80% here when the CAEC needs 55%?

The real test needs 55%. We set a higher bar so that a pass here is a good sign you are ready, not just close.

Where do I register for the CAEC?

Eligibility rules, fees and testing centres depend on your province or territory, so start with your provincial or territorial CAEC page. You then create an account on the CAEC digital platform and book a test at a testing centre.

Ist die Bescheinigung akkreditiert oder offiziell anerkannt?

Nein. Es ist eine private Teilnahmebescheinigung, nur für Ihr Wissen. Sie ist von keiner Behörde, Zulassungsstelle, Aufsichtsbehörde oder Bildungseinrichtung anerkannt, akkreditiert oder genehmigt und ersetzt keine gesetzlich vorgeschriebene Lizenz, Zertifizierung oder Ausbildung.
