Free SC Ready Science Inquiry & Reasoning Questions and Answers

Question 1

What is the first step in the scientific method?

Accepted Answer

Make an observation

Answer

The scientific method typically begins with making an observation about the natural world that sparks a question. This initial observation then leads to forming a hypothesis, designing experiments, and collecting data to test that hypothesis.

Question 2

Which variable is deliberately changed in an experiment?

Accepted Answer

Independent variable

Answer

In an experiment, the independent variable is the factor that the scientist intentionally changes or manipulates to observe its effect. It is the "cause" in a cause-and-effect relationship being studied. The dependent variable, in contrast, is the factor that is measured and is expected to change in response to the independent variable.

Question 3

What is the purpose of a control group in an experiment?

Accepted Answer

To provide a standard for comparison

Answer

A control group in an experiment is a group that does not receive the treatment or manipulation of the independent variable. Its purpose is to serve as a baseline or standard against which the experimental group's results can be compared, helping to ensure that any observed changes are due to the independent variable and not other factors.

Question 4

Which of these is an example of a quantitative observation?

Accepted Answer

The temperature is 25°C

Answer

A quantitative observation involves measurements and numerical data. Stating that "The temperature is 25°C" provides a specific numerical value, making it a quantitative observation. Other options describe qualities without numbers, making them qualitative observations.

Question 5

What should you do if your experimental results don't support your hypothesis?

Accepted Answer

Revise the hypothesis and design new experiments

Answer

If experimental results do not support the hypothesis, it indicates that the initial hypothesis may be incorrect or incomplete. The appropriate scientific response is to analyze the data, revise the hypothesis based on the new understanding, and then design new experiments to test the revised hypothesis. This iterative process is fundamental to scientific discovery.
