    Study Notes

    What is a Scientific Hypothesis

    • A scientific hypothesis is an educated guess that is testable, clear, and based on observations and prior knowledge, written before an experiment takes place.

    Creating and Developing a Hypothesis

    • Step 1: Ask a specific and researchable question, using who, what, when, where, why, or how.
    • Step 2: Conduct preliminary research, gathering reliable sources, case studies, and personal observations to inform the hypothesis.
    • Step 3: Answer the initial question based on preliminary research.
    • Step 4: Write a hypothesis, including variables and predicted results, using an if/then statement.

    Characteristics of a Good Hypothesis

    • A good hypothesis is testable, clear, and includes variables and predicted results.
    • Examples of well-written hypotheses:
      • "If a person gets 8 hours of sleep at night, then their memory during the day will improve."
      • "If teeth are brushed twice a day, then a person is less likely to develop cavities."

    Characteristics of a Poor Hypothesis

    • A poor hypothesis is not testable, lacks variables, is an opinion, or is not based on facts.
    • Examples of poorly-written hypotheses:
      • "It doesn't matter if you do your homework or not."
      • "Lightning is caused by ghosts in the sky."
      • "Fertilizer is better for flowers than it is for vegetable plants."
      • "Ice cream tastes the best at midnight"
