    Which events occur first in the scientific method

    • Hypothesis

    • Ask a Question

    • Collect Data

    Correct Answer
    A. Ask a Question
    Explanation
    In the scientific method, the first step is to ask a question. This is because the scientific method is a systematic approach to problem-solving, and it begins with identifying a problem or a question that needs to be answered. Once a question is formulated, the next steps in the scientific method, such as forming a hypothesis and collecting data, can be carried out to find a solution or answer to the initial question. Therefore, asking a question is the first event that occurs in the scientific method.

    Rate this question:

    What do you do to test a hypothesis?

    • Guess

    • Collect Data

    Correct Answer
    A. Collect Data
    Explanation
    To test a hypothesis, collecting data is essential. This involves gathering relevant information, observations, or measurements that are necessary to analyze and evaluate the hypothesis. Collecting data allows for an objective assessment of the hypothesis and provides evidence to support or refute it. Without data, it would be impossible to draw any meaningful conclusions or make informed decisions regarding the validity of the hypothesis.

    Would a scientist want to test more than one item (variable) at a time?

    • Yes

    • No

    Correct Answer
    A. No
    Explanation
    A scientist would not want to test more than one item (variable) at a time because it would make it difficult to determine which variable is responsible for any observed changes or results. By testing one variable at a time, scientists can isolate and control the factors being studied, allowing them to accurately analyze the effects of each individual variable. This approach helps in establishing cause-and-effect relationships and drawing reliable conclusions from the experiments.

     If a scientist notices something unusual, he comes up with a question that will help him solve the problem, tests to see if the explanation was correct, and then tells his friends he has developed a new theory, what step is he leaving out?

    • Observations

    • Hypothesis

    Correct Answer
    A. Hypothesis
    Explanation
    The scientist is leaving out the step of conducting experiments to test the hypothesis. After formulating a hypothesis, the scientist should design and conduct experiments to gather data and evidence that either supports or refutes the hypothesis. Only after conducting experiments and analyzing the results can the scientist confidently develop a new theory based on the findings.
