Questionário temático 1: The Science test and the nature of science
-
Pergunta 1 de 17
Mostrar resposta
Resposta: D. 35
The CAEC Science test has 35 questions.
-
Pergunta 2 de 17
Mostrar resposta
Resposta: B. 90 minutes
You have 90 minutes for the 35 Science questions.
-
Pergunta 3 de 17
Mostrar resposta
Resposta: D. Scientific inquiry skills
Scientific inquiry skills make up 60–85% of the test, far more than the other two strands.
-
Pergunta 4 de 17
Mostrar resposta
Resposta: C. 55%
Every CAEC test, including Science, needs at least 55% to meet the minimum standard.
-
Pergunta 5 de 17
Mostrar resposta
Resposta: A. An observation
It describes only what the student can see. An observation uses the senses or a tool and adds no explanation.
-
Pergunta 6 de 17
Mostrar resposta
Resposta: 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.
-
Pergunta 7 de 17
Mostrar resposta
Resposta: 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.
-
Pergunta 8 de 17
Mostrar resposta
Resposta: 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.
-
Pergunta 9 de 17
Mostrar resposta
Resposta: C. Ideas can change when new evidence is found
Science is ongoing inquiry. Ideas are kept, changed or replaced when new evidence appears.
-
Pergunta 10 de 17
Mostrar resposta
Resposta: 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.
-
Pergunta 11 de 17
Mostrar resposta
Resposta: 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.
-
Pergunta 12 de 17
Mostrar resposta
Resposta: 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.
-
Pergunta 13 de 17
Mostrar resposta
Resposta: 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.
-
Pergunta 14 de 17
Mostrar resposta
Resposta: 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.
-
Pergunta 15 de 17
Mostrar resposta
Resposta: 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.
-
Pergunta 16 de 17
Mostrar resposta
Resposta: D. Selective reporting
Selective reporting means sharing only the results that support what you want and leaving out the rest.
-
Pergunta 17 de 17
Mostrar resposta
Resposta: 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.

O exame real: 55% on each CAEC test
O que saber antes do exame
- 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.
Perguntas frequentes
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.
O certificado é acreditado ou reconhecido oficialmente?
Não. É um certificado de conclusão privado, apenas para o seu conhecimento. Não é reconhecido, acreditado nem aprovado por nenhum governo, entidade licenciadora, regulador ou instituição de ensino e não substitui qualquer licença, certificação ou formação exigida por lei.
