Cornell Notes Topic/Objective: Scientific Method Essential Question- Should be answered in the summary What is the scientific method?

Scientific Method Procedures Observation The foundation of the scientific method Leads to a question regarding the event or characteristic Hypothesis Is an “educated guess” It is a tentative cause and effect statement. Has to be testable Is rejected or accepted at the conclusion of an experiment

Terminology Hypothesis: a possible answer to a scientific question (Q: “How will studying affect my test score?” Hypo: “If I study for… then my test score will…”) Prediction: states the expected outcome of an experiment designed to test the hypothesis (“My test score will…”) Inference: a logical interpretation based on prior knowledge and experience (“I have always done poorly in science, so I will do poorly this time too.”)

Scientific Method Procedures Experiment Experiments must be repeatable and reproducible. dependent variable - this will be the single observation, or the result we will be observing. independent variable - this will be the single variable we elect to manipulate. controlled variables - these are factors that we will keep constant (“keep controlled”) during the experiment, so that they do not affect the dependent variable.

What is the Purpose of a Control? Controls are NOT being tested Controls are used for COMPARISON

Scientific Method Procedures Collect/ Analyze Data Always report ALL results (the good, the bad, and the ugly!) Look for patterns in the data Conclusion WHAT HAPPENED AND WHY?

Lesson 2: Scientific Method

PSEUDOSCIENCE: A pseudoscience is a set of ideas put forth as scientific when they are not scientific. Clairvoyance is the art of 'seeing' beyond the five senses. Astrology comprises several systems of divination based on the premise that there is a relationship between astronomical phenomena and events in the human world. Psychokinesis, sometimes referred to as "telekinesis" or "mind over matter," is the ability to influence the movement of matter or energy through mental processes.
