    An arrangement of things or events in certain order is _________________

    • A comparison

    • A contrast

    • A sequence

    • A hypothesis

    Correct Answer
    A. A sequence
    Explanation
    An arrangement of things or events in a certain order is referred to as a sequence. In a sequence, each element follows a specific pattern or order, allowing for a logical progression from one item to the next. This term is commonly used in mathematics, where sequences are often studied and analyzed. It is important to note that a sequence implies a systematic arrangement, rather than a comparison, contrast, or hypothesis, which involve different concepts and ideas.

  • 8. 

    There are never variables or controls in an observational study

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Observational studies do not involve variables or controls. In an observational study, researchers simply observe and collect data on a group of individuals without manipulating any variables or implementing controls. However, this statement is incorrect as variables and controls can be present in other types of studies, such as experimental studies. In experimental studies, researchers manipulate variables and implement controls to determine cause-and-effect relationships. Therefore, the correct answer is False.

    In a controlled experiment, the independent variable is the factor that is changed by the researcher.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    In a controlled experiment, the independent variable is the factor that is purposely manipulated or changed by the researcher. This variable is independent because it is not influenced by any other factors in the experiment. By manipulating the independent variable, the researcher can observe and measure its effects on the dependent variable, which is the outcome or response being measured. This allows the researcher to determine if there is a cause-and-effect relationship between the independent variable and the dependent variable.

    Rate this question:

  • 11. 

    Scientists may draw conclusions from the results of ____________________.

    • Experiments

    • Observational studies

    • Both experiments and observational studies

    • Neither experiments nor observational studies

    Correct Answer
    A. Both experiments and observational studies
    Explanation
    Scientists may draw conclusions from the results of both experiments and observational studies because both methods provide valuable data that can be analyzed and interpreted. Experiments involve manipulating variables in a controlled setting to observe the effects, allowing scientists to establish cause and effect relationships. On the other hand, observational studies involve observing and analyzing existing data without manipulating variables, providing insights into natural behaviors and associations. By considering the results from both types of studies, scientists can gain a more comprehensive understanding of a phenomenon and make informed conclusions.

    Scientists use all the steps in a scientific method in the same order to solve different problems.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement is false because scientists do not always use all the steps in the scientific method in the same order to solve different problems. The scientific method is a flexible framework that can be adapted and modified based on the specific problem or research question being addressed. Scientists may skip certain steps or modify the order of the steps based on the nature of the problem and the available resources. Therefore, the statement that scientists always use all the steps in the scientific method in the same order is incorrect.

    • Independent variable

    • Dependent variable

    • Constant

    • Control

    Correct Answer
    A. Independent variable
    Explanation
    The correct answer is independent variable. In an experiment, the independent variable is the factor that is intentionally changed or manipulated by the researcher. In this case, the amount of light is being intentionally varied to observe its effect on the experiment.

    Rate this question:

  • 17. 

    Using scientific methods means doing a controlled experiment

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement "Using scientific methods means doing a controlled experiment" is false. While controlled experiments are one of the scientific methods used to gather data and test hypotheses, they are not the only method. Scientific methods also include observation, data analysis, hypothesis formulation, and theory development. These methods are used to systematically investigate and understand natural phenomena, and they may not always involve a controlled experiment.

  • 18. 

    Looking for differences in objects or events is _________________.

    • Comparing

    • Contrasting

    • Infering

    • Hypothesizing

    Correct Answer
    A. Contrasting
    Explanation
    Contrasting involves identifying and highlighting the differences between objects or events. It is the process of examining two or more things to identify their dissimilarities. This can be done by comparing their characteristics, features, or qualities that set them apart from each other. Contrasting helps in gaining a deeper understanding of the objects or events by focusing on their disparities rather than their similarities.

  • 19. 

    A variable in an experiment that stays the same is ______________

    • An independent variable

    • A dependent variable

    • A constant

    • A control

    Correct Answer
    A. A constant
    Explanation
    In an experiment, a constant is a variable that remains unchanged throughout the study. It is used as a baseline or reference point to compare the effects of other variables. By keeping the constant constant, researchers can isolate and identify the specific impact of the independent variable on the dependent variable. Therefore, a constant is the correct answer as it does not change during the experiment.

    Rate this question:

  • 20. 

    /in the experiment whose data is shown (above), amount of time is the _________________

    • Independent variable

    • Dependent variable

    • Constant

    • Control

    Correct Answer
    A. Constant
    Explanation
    The given answer, "constant," is correct because the question states that the data shown in the experiment is about the "amount of time." Since the amount of time is not being manipulated or changed, it remains constant throughout the experiment. Therefore, it is not the independent variable (which is manipulated), the dependent variable (which is measured in response to the independent variable), or the control (which is used as a baseline for comparison).

    Rate this question:

  • 21. 

    If the results of a study do not support a hypothesis, it means that the hypothesis is wrong.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement is false because the results of a study not supporting a hypothesis does not necessarily mean that the hypothesis is wrong. It could mean that the study was flawed, the data was not accurately collected or analyzed, or there were other factors that influenced the results. It is important to consider alternative explanations and further investigate before concluding that the hypothesis is wrong.
