7th Grade Chapter 1 Science Test - Quiz

Quiz on the Scientific Method, Vocabulary, and Microscope parts.


Questions and Answers
  • 1. 

    Name the Scientific Method Steps. Seperate each step by comma and capatilize each answer.

    Explanation
    The scientific method steps are as follows: question, research, hypothesis, experiment, analyze, and report results. This process begins with asking a question, followed by conducting research to gather information. A hypothesis is then formulated based on the research, which is tested through an experiment. The data collected from the experiment is then analyzed to draw conclusions, and finally, the results are reported.

    Rate this question:

  • 2. 

    Define hypothesis.

    • A.

      possible explanation

    • B.

      Conclusion

    • C.

      Act of predicting

    • D.

      consider detail and subject

    Correct Answer
    A. possible explanation
    Explanation
    A hypothesis is a possible explanation for a phenomenon or a proposed solution to a problem. It is a statement that can be tested and evaluated through research and observation. A hypothesis is not a conclusion or a final answer, but rather an educated guess that is based on prior knowledge and observations. It is an act of predicting or suggesting a potential explanation for a specific situation or event. When formulating a hypothesis, it is important to consider the details and subject matter related to the phenomenon being studied.

    Explanation
    The term "prediction" refers to making a guess or estimation about future events or outcomes. It involves using available information and analyzing patterns or trends to anticipate what might happen in the future. Predictions are not certainties, but rather educated guesses based on logical reasoning or evidence. They can be made in various fields such as science, economics, sports, and weather forecasting, among others.

    Correct Answer
    A. Solution made by using senses
    Explanation
    The correct answer is "solution made by using senses". This means that to infer something is to come to a conclusion or make a judgment based on observations or information gathered through the use of our senses, such as sight, hearing, touch, taste, or smell. Inferences are often made when there is not direct or explicit evidence, but rather an interpretation or deduction based on the available information.

    Rate this question:

  • 7. 

    Define measurement.

    • A.

      Exact number, must have a unit and a number

    • D.

      Believe to be

    Correct Answer
    A. Exact number, must have a unit and a number
    Explanation
    Measurement refers to the process of quantifying or determining the size, amount, or degree of something. It involves obtaining an exact numerical value, which must be accompanied by a unit of measurement. This ensures that the measurement is standardized and can be understood universally. Without a unit and a number, a measurement would lack specificity and would not provide meaningful information. Therefore, an exact number with a unit is a fundamental requirement for accurate and reliable measurements.

    Correct Answer
    A. Gathering and organizing information
    Explanation
    The correct answer is "gathering and organizing information." This definition accurately captures the essence of science, which involves the systematic collection and analysis of data to gain knowledge and understanding about the natural world. By gathering and organizing information, scientists can make observations, form hypotheses, conduct experiments, and draw conclusions. This process is essential for advancing our understanding of various phenomena and developing theories and explanations based on empirical evidence.

    Correct Answer
    A. Scientific investigation with 2 groups(controlled group and experimental group)
    Explanation
    A controlled experiment is a scientific investigation that involves two groups: a controlled group and an experimental group. The controlled group serves as a baseline or comparison, while the experimental group is exposed to a specific variable or condition being tested. By comparing the results of both groups, scientists can determine the effects of the variable being studied. This type of experiment helps to establish cause-and-effect relationships and minimize confounding factors that could influence the results.
