Question 1

Which of the following best describes the relationship between science and mathematics?

Accepted Answer

Mathematics provides unambiguous expressions of scientific concepts through equations such as $$F = ma.$$

Question 2

Eratosthenes estimated the circumference of the Earth using geometric reasoning. Which equation did he use to relate the angle of the Sun's rays and the distance between two cities?

Accepted Answer

He used $$\frac{\alpha}{360} = \frac{d}{C}$$ where $$\alpha is $$the measured angle, $$d is $$the distance, and $$C is $$the circumference.

Question 3

Which of the following is NOT a scientific hypothesis?

Accepted Answer

Undetectable particles are some of nature’s secrets.

Question 4

Aristarchus used geometric reasoning to estimate the relative sizes and distances of the Earth, Moon, and Sun. Which principle did he rely on?

Accepted Answer

The angle subtended by the Moon and Sun during an eclipse can be used to estimate their distances.

Question 5

Which step is NOT typically part of the scientific method?

Accepted Answer

Ignoring contradictory evidence.

Question 6

A scientific theory is best described as:

Accepted Answer

A vast synthesis of well-tested hypotheses and facts.

Question 7

Which of the following statements about facts and theories in science is correct?

Accepted Answer

Theories interpret facts and both can change with new evidence.

Question 8

Which of the following is a real-world example of a scientific hypothesis that was later proven wrong?

Accepted Answer

The Moon is made of green cheese.

Question 9

Which of the following best illustrates the difference between science and technology?

Accepted Answer

Science is concerned with gathering and organizing knowledge, while technology applies that knowledge for practical purposes.

Question 10

Which of the following is a characteristic of the scientific attitude?

Accepted Answer

Willingness to admit error and change one's mind based on evidence.

Question 11

Which equation is commonly used in physics to express the relationship between force, mass, and acceleration?

Accepted Answer

$$F = ma$$

Question 12

Which of the following best describes the domain of science compared to art and religion?

Accepted Answer

Science is concerned with discovering and recording natural phenomena (cosmic order).

Question 13

Which of the following is a multi-step process that integrates observation, hypothesis, prediction, and experimentation?

Accepted Answer

The scientific method.

Question 14

Which of the following is a law or principle in science?

Accepted Answer

A hypothesis that has been tested repeatedly and has not been contradicted.

Question 15

Which of the following best explains why physics is considered the foundation for other sciences?

Accepted Answer

Physics provides fundamental principles that underlie chemistry, biology, geology, and astronomy.

Question 16

Which of the following is an example of a fact in science?

Accepted Answer

A close agreement by observers about the same phenomenon.

Question 17

Which of the following statements about the scientific method is correct?

Accepted Answer

Scientists often use common steps such as observation, hypothesis, prediction, experimentation, and conclusion.

Question 18

Which of the following is a real-world application of scientific reasoning?

Accepted Answer

Using geometric reasoning to estimate the size of the Earth.

Question 19

Which of the following best describes the integration of science and mathematics?

Accepted Answer

Science and mathematics were integrated about four centuries ago, allowing scientific ideas to be expressed unambiguously in mathematical terms.

Question 20

Which of the following is a characteristic of a scientific hypothesis?

Accepted Answer

It is an educated guess presumed to be factual until supported by experiment.
