  • To prove a hypothesis is correct
  • To disprove a competitor's hypothesis
  • What is the role of a hypothesis in an experiment?

  • To predict the outcome of the experiment (correct)
  • To state the question being investigated
  • To analyze the data collected
  • To design the experiment's procedure
  • What should you do with your data after collecting it in an experiment?

  • Analyze it to see if it answers your question (correct)
  • Discard it if it doesn't support your hypothesis
  • Use it to design a new experiment

    Study Notes

    Scientific Evidence

    • Scientific evidence refers to the data collected during an experiment.
    • The purpose of scientific evidence is to answer the research question and support or reject the hypothesis.

    Analyzing Scientific Evidence

    • To analyze the data, you need to determine if it answers your question and supports your hypothesis.
    • Ask yourself what you would expect to see if your hypothesis is true.
    • Look for the point where the data begins to boil in each type of water.
    • Compare the boiling points of salt water and fresh water to determine if the data fits the hypothesis.

    Does the Data Fit?

    • If the data fits the hypothesis, the boiling point of salt water should be higher than that of fresh water.
    • Replicating the result is crucial; if the data varies each time, it may indicate an error in the experiment.

    Interpreting the Data

    • Interpreting the data means explaining what the data says.
    • Interpretation occurs when checking if the data fits the hypothesis.
    • The interpretation of the data should clearly state the findings, e.g., the boiling point of salt water is higher than that of fresh water.
    • Visual aids like charts or diagrams can be used to illustrate the interpretation.
