  2. Scientific Methods • An organized plan for gathering, organizing and communicating information is called the ______________________________. • The goal of the scientific method is to ________________________________________. • Steps in the Scientific Method: • ________________________ • ________________________ • ________________________ • ________________________

  3. Observations & Hypothesis • An observation is information obtained through your __________________. • Repeated observations are known as ________________. • Observations may be combined to form a ________________. • A hypothesis is a proposed answer to a question. • For a hypothesis to be useful, it must be __________________. • ______________ are performed to test a hypothesis.

  4. Experiment (Test) • Performed to test the ________________. • Any factor that can change is a _________. • The variable that causes a change in another is the ______. • The variable that changes in response to the manipulated variable is the ______. • __________________ are used to examine the relationship between a manipulated and responding variable. Only the ___________ variable is deliberately changed at a time. • All other variables are kept constant, or ________________.

  5. Drawing Conclusions • Based on collected ___________, scientific evidence can now support or not support the hypothesis. • If the data does not support the hypothesis, a scientist can ______________________________ _________________________________________. • True or False: The same experiment can be used to test the new or revised hypothesis.

  6. Theory • A scientific theory is a well-tested _____________ for a set of observations or experimental results. • Example: _____________________________ • Developed AFTER much support through many experiments. • True or False: Theories are never proved. • If the facts support them, theories become stronger. • If the theory fails to explain new facts and discoveries, the theory may be revised or a _____________________________________________.

  7. Scientific Laws • A statement that summarizes a pattern found in nature is called a _______________________. • Example: _______________________________ • Why isn’t Newton’s Law called a theory? ________ ______________________________________________ • Copy the bold statement from pg. 9 here:

  8. Rain Experiment • Page 9, first paragraph: • Observation: • Hypothesis: • Experiment: • Conclusion: • Can this be called a theory?

  9. Scientific Models • A representation of an object or event is called a ____________________. • Why are models useful? • Example of a physical object: • Example of an idea:

  10. Laboratory Safety • What is the single most important rule for laboratory safety?
