Correct Answer
A. Scientific MethodExplanation
The scientific method is a body of techniques for investigating phenomena, acquiring new knowledge, or correcting previous knowledge. It is a systematic approach that involves making observations, formulating a hypothesis, conducting experiments, analyzing data, and drawing conclusions. The scientific method is widely used in various fields of study to ensure that research is conducted in a rigorous and objective manner. It helps to minimize bias and errors, and allows for the replication and verification of results.Rate this question:

Observing involves collecting data and make measurements during an experiment.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Observing involves actively using the senses to gather information and make qualitative observations, rather than collecting data and making measurements. It is a process of gathering information through visual, auditory, or other sensory means, without necessarily quantifying or measuring the data. Therefore, the statement is false.Rate this question:

_____ is something that has amount, magnitude, or size. It is NOT the same as a measurement.
- A.
Quantity
- B.
Variable
- C.
Theory
- D.
Control
- E.
Independent Variable
Correct Answer
A. QuantityExplanation
Quantity refers to something that has amount, magnitude, or size. It is different from a measurement because a measurement is the process of determining the quantity of something using a specific unit or scale. In other words, a quantity is the actual value or magnitude of something, while a measurement is the act of quantifying or assigning a value to that quantity. Therefore, quantity and measurement are distinct concepts, with quantity representing the actual amount or size of something.Rate this question:

Theory
- D.
Control
- E.
Independent Variable
Correct Answer
C. TheoryExplanation
A theory is a set of statements or principles devised to explain a group of facts or phenomena, especially one that has been repeatedly tested or is widely accepted. Theories are based on evidence and research, and they provide a framework for understanding and explaining various phenomena. They are often used in scientific fields to explain and predict observations and outcomes.Rate this question:

- E.
Model
Correct Answer
E. ModelExplanation
A model is often an explanation of how phenomena occur and how data or events are related. Models are simplified representations of complex systems or processes that help us understand and predict their behavior. They can be physical, mathematical, or conceptual in nature, and are used in various fields such as science, engineering, and economics. Models provide a framework for organizing and interpreting data, allowing us to make predictions and test hypotheses about the real world.Rate this question:

A(n) _____ involves collecting data and make measurements. (Note: Please enter your answer using all lower case letters.)
Correct Answer
observationExplanation
An observation involves collecting data and making measurements by using the senses to gather information about the world around us. It is a process of carefully watching or noting something in order to gain knowledge or understanding. Observations can be made through direct observation, using instruments or tools to measure, or through the use of technology to collect data.Rate this question:

Qualitative data deals with descriptions (non-numerical). Data can be observed but not measured. Please select qualitative data from the list below.
- A.
Colors
- B.
Textures
- C.
Smells
- D.
45.6 meters
- E.
Taste
- F.
Shape
- G.
20.6 Liter of diet soda
Correct Answer(s)
A. Colors
B. Textures
C. Smells
E. Taste
F. ShapeExplanation
Qualitative data refers to information that is descriptive in nature and cannot be measured numerically. It includes characteristics, qualities, and attributes. In this case, the correct answer includes colors, textures, smells, taste, and shape. These are all examples of qualitative data because they are descriptive and cannot be quantified or measured in numerical terms.Rate this question:

_____ Data is helpful in evaluation because it provides quantifiable and easy to understand results. Such as the atomic radii measured in picometers.
Correct Answer(s)
QuantitativeExplanation
Quantitative data refers to numerical information that can be measured and expressed in terms of quantity or amount. It is helpful in evaluation because it provides quantifiable and easy to understand results. For example, in the given context, the atomic radii measured in picometers is a quantitative data point that allows for precise comparisons and analysis.Rate this question:

_____ is a proposed explanation for a phenomenon. It serves as a basis for making predictions and carry out further experiments.
Correct Answer(s)
HypothesisExplanation
A hypothesis is a proposed explanation for a phenomenon that is based on existing knowledge or observations. It serves as a starting point for scientific investigations, providing a basis for making predictions and designing experiments to test its validity. A hypothesis helps researchers to formulate specific questions and develop a systematic approach to gather evidence and analyze data. It is an essential component of the scientific method, allowing scientists to advance their understanding of the natural world.Rate this question:

- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The goal of any scientific method is indeed to solve a problem or to better understand an observed event. Scientific methods involve systematically gathering data, conducting experiments, and analyzing results in order to gain knowledge and find solutions to problems. By following a structured approach, scientists aim to uncover the truth and expand our understanding of the world around us. Therefore, the statement is true.Rate this question:

A(n) _____ variable responses to the independent variable in the experiment or investigation.
- A.
Dependent
- B.
Independent
- C.
Quantity
- D.
Control
- E.
Scientific
Correct Answer
A. DependentExplanation
The correct answer is "dependent". In an experiment or investigation, the dependent variable is the variable that is being measured or observed and is expected to change in response to the independent variable. It is called "dependent" because its value depends on the manipulation of the independent variable.Rate this question:

A(n) _____ experiment is an experiment in which only one variable, the manipulated variable is deliberately changed at a time. (Note: Please enter your answer in all lower case letters.)
Correct Answer
controlledExplanation
In a controlled experiment, only one variable, known as the manipulated variable, is intentionally changed at a time. This allows researchers to isolate the effects of that specific variable and determine its impact on the outcome of the experiment. By controlling all other variables, any changes in the outcome can be attributed to the manipulated variable alone.Rate this question:
- 15.
A(n) _____ is a word to describe each factor that changed in the experiment (investigation). (NOTE: Please use all lower case letters in your answer.)
Correct Answer
variableExplanation
In an experiment or investigation, a variable is a word used to describe each factor that changes. Variables can be manipulated or controlled by the researcher to observe their effects on the outcome of the experiment. They are important in determining cause and effect relationships and understanding the impact of different factors on the results.Rate this question:
