Questions and Answers
  • 1. 

    When designing an experiment, the first step is to ___________.

    • A.

      State a hypothesis

    • B.

      Draw conclusions

    • C.

      List a procedure

    • D.

      Analyze the data

    • E.

      State the problem

    Correct Answer
    E. State the problem
    Explanation
    When designing an experiment, the first step is to state the problem. This involves identifying and clearly defining the question or issue that the experiment aims to address. By stating the problem, researchers can establish a clear focus for their experiment and determine the specific objectives they want to achieve. This step is crucial as it helps guide the entire experimental process, from formulating a hypothesis to collecting and analyzing data, ultimately leading to drawing conclusions and determining the significance of the findings.

  • 2. 

    A factor that does not change in an experiment is the ___________.

    • A.

      Control

    • B.

      Hypothesis

    • C.

      Data

    • D.

      Constant

    • E.

      Independent variable

    Correct Answer
    D. Constant
    Explanation
    In an experiment, a constant is a factor that remains unchanged throughout the entire process. It is used as a baseline or reference point to compare the effects of other variables. By keeping certain factors constant, researchers can isolate the impact of the independent variable on the dependent variable. This allows for a more accurate analysis and interpretation of the results. Therefore, the correct answer is constant.

  • 3. 

    The reason for wearing safety goggles in the laboratory is to ______________.

    • A.

      Improve eyesight.

    • B.

      Protect the eyes from harmful substances

    • C.

      Protect the clothes from chemical spills

    • D.

      Keep your clothes away from the fire

    • E.

      Apply the procedure

    Correct Answer
    B. Protect the eyes from harmful substances
    Explanation
    Safety goggles are worn in the laboratory to protect the eyes from harmful substances. In a laboratory setting, there are various chemicals and materials that can cause eye irritation or damage if they come into contact with the eyes. Safety goggles provide a physical barrier between the eyes and these substances, preventing any potential harm. Wearing safety goggles is an important safety precaution to ensure the well-being and protection of the eyes while working in the laboratory.

    An organized process used to gather observations and test a hypothesis is _________.

    • A.

      A problem

    • B.

      An experiment

    • C.

      An experience

    • D.

      An exercise

    • E.

      A constant

    Correct Answer
    B. An experiment
    Explanation
    An experiment is an organized process used to gather observations and test a hypothesis. It involves carefully designed procedures and controlled variables to systematically investigate a specific question or phenomenon. Through an experiment, scientists can collect data, analyze results, and draw conclusions that contribute to the understanding of a particular subject. This methodical approach allows for the replication and verification of findings, making it an essential tool in scientific research.

  • 5. 

    The lightbulb is an example of ____.

    • A.

      Pure science

    • B.

      Technology

    • C.

      A dependent variable

    • D.

      An exercise

    • E.

      A hypothesis

    Correct Answer
    B. Technology
    Explanation
    The lightbulb is an example of technology because it is a man-made invention that utilizes scientific principles to produce light. Technology refers to the application of scientific knowledge for practical purposes, and the lightbulb is a perfect example of this as it harnesses electricity to create artificial light.

    Rate this question:

  • 6. 

    An idea, structure, or system that can be used to represent something you are trying to explain is a ____________.

    • A.

      Model

    • B.

      Constant

    • C.

      Control

    • D.
