Scientific method test #1

Question 1

What is science?

Answer 1

Process of gaining knowledge about the natural world.

Question 2

Why is science always changing?

Answer 2

Because scientists are always gaining more knowledge and making new discoveries. So, science changes because we’re constantly learning and improving our knowledge.

Question 3

Is science rigid or set in stone?

Answer 3

Neither. It’s a flexible framework for scientific inquiry.

Question 4

Do scientists learn about the universe in the same way?

Answer 4

No, scientists use different methods to learn about the universe, depending on what they are studying. They might use experiments, observations, or math to discover new things.

Question 5

What is an Observation?

Answer 5

An observation is using your senses to notice and describe something. Scientists use it to gather information. (Sight, hear, touch, taste, and smell).

Question 6

Why are making good and careful observations important in science?

Answer 6

Good and careful observations are important in science because they help scientists gather accurate information, leading to better understanding and reliable results.

Question 7

What is an inference?

Answer 7

or guess you make based on observations and what you already know.

Question 8

Give an example of an inference

Answer 8

You walk outside and notice the ground is wet. The observation is that the ground is wet and the inference is that it rained.

Question 9

In science, what is a hypothesis?

Answer 9

An educated guess or prediction between two variables.

Question 10

How can a scientist determine if their hypothesis is correct or not?

Answer 10

A scientist tests their hypothesis with experiments or observations. If the results support the hypothesis, it’s considered correct; if not, the hypothesis needs to be changed or rejected.

Question 11

What is a variable in a controlled experiment?

Answer 11

A variable is anything that can change or be changed.

Question 12

How are controlled variables different from experimental and dependent variables?

Answer 12

Controlled variables are kept constant to make sure they don’t affect the experiment. Experimental variables are changed to test the hypothesis, and dependent variables are what you measure to see if the experimental variables had an effect.

Question 13

Experimental variables

Answer 13

Experimental variables are changed to test the hypothesis.

Question 14

Dependent variables

Answer 14

dependent variables are what you measure to see if the experimental variables had an effect.

Question 15

Why are there two groups in most experiments?

Answer 15

There are two groups in experiments: one group doesn’t change (control) and the other gets the treatment (experimental). This helps see if the treatment has an effect.

Question 16

What are the two groups in experiments? (What groups are these referred to)

Answer 16

The control group and the experiment group.

Question 17

How is one group different than the other?

Answer 17

The control group doesn’t receive the treatment and stays the same, while the experimental group gets the treatment or change being tested. This helps compare the effects.

Question 18

What is data?

Answer 18

Data is information or facts collected through observations or experiments. It helps scientists analyze and understand things.

Question 19

How is qualitative data different than quantitative data?

Answer 19

Qualitative data describes qualities or characteristics (like colors or feelings), while quantitative data uses numbers and measurements (like height or weight).

Question 20

Provide three examples of qualitative data

Answer 20

Favorite color – Describing someone’s preferred color, like blue or red.

Texture of a surface – Noting if something feels smooth or rough.

Emotion expressed – Describing how a person feels, like happy or sad.

Question 21

Provide three examples of quantitative data.

Answer 21

Height of a person – Measured in inches or centimeters.

Number of students in a class – Counted as 20 students, for example.

Temperature – Measured in degrees Celsius or Fahrenheit.

Question 22

Can all hypothesis be tested with an experiment? Explain:

Answer 22

Not all hypotheses can be tested with an experiment. Some might need observations or studies instead, especially if they involve things that can’t be controlled or changed in a lab.

Question 23

What is a theory in science?

Answer 23

In science, a theory is a well-tested explanation of how things work based on a lot of evidence and observations.

Question 24

How is theory in everyday language different from scientific theory?

Answer 24

In everyday language, “theory” means a guess or opinion. In science, a “theory” is a well-tested explanation based on lots of evidence and observations.

Question 25

A scientist wanted to study the affect of a drug on the blood pressure of rats. The experimental group consisted of a salt solution with the drug. What should the control group consist of?

Answer 25

Salt solution not containing the drug.

Question 25

What is an advantage of a peer reviewed scientific paper?

Answer 25

An advantage of
A peer-reviewed paper is that it’s checked by other experts to make sure it’s accurate and reliable before it’s published

Question 26

Based on her experiment what are the dependent and independent variables?

Answer 26

Dependent is the blood pressure.

Independent is the drug solution.
