• What is the first step in the scientific method?

  Observation
• What is a hypothesis?

  It is an educated guess or explanation about an observed object or event.
• What does experimentation involve in the scientific method?

  It involves testing the hypothesis through controlled procedures.
• What is the purpose of gathering data in the scientific method?

  To collect information that supports or refutes the hypothesis.
• Why is communicating results important in the scientific method?

  It allows others to understand and verify the findings of the research.
• What are the six basic science process skills?

  1. Observing
  2. Inferring
  3. Measuring
  4. Classifying
  5. Predicting
  6. Communicating
