  3. Vraag 3 van 17

    Which strand makes up the largest share of the CAEC Science test?
    Toon antwoord

    Antwoord: D. Scientific inquiry skills

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

  4. Vraag 4 van 17

    What score do you need to pass the CAEC Science test?
    Toon antwoord

    Antwoord: C. 55%

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

  5. Vraag 5 van 17

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

    Antwoord: A. An observation

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

  6. Vraag 6 van 17

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

    Antwoord: 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. Vraag 7 van 17

    Which question can be answered by a scientific investigation?
    Toon antwoord

    Antwoord: 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. Vraag 8 van 17

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

    Antwoord: 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. Vraag 9 van 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?
    Toon antwoord

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

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

  10. Vraag 10 van 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?
    Toon antwoord

    Antwoord: 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. Vraag 11 van 17

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

    Antwoord: 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. Vraag 12 van 17

    Why do researchers try to use a large, randomly chosen sample?
    Toon antwoord

    Antwoord: 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. Vraag 13 van 17

    What happens during peer review?
    Toon antwoord

    Antwoord: 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. Vraag 14 van 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?
    Toon antwoord

    Antwoord: 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. Vraag 15 van 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?
    Toon antwoord

    Antwoord: 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. Vraag 16 van 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?
    Toon antwoord

    Antwoord: D. Selective reporting

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

  17. Vraag 17 van 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?
    Toon antwoord

    Antwoord: 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.

Wat je moet weten voor het examen

  • 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.

Veelgestelde vragen

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.

Is het certificaat geaccrediteerd of officieel erkend?

Nee. Het is een privé bewijs van deelname, alleen voor je kennis. Het is niet erkend, geaccrediteerd of goedgekeurd door een overheid, vergunningsinstantie, toezichthouder of onderwijsinstelling, en het vervangt geen wettelijk verplichte vergunning, certificering of opleiding.
