Chapter 1 Basics - Scientific Method / Process Organization of Life & Themes Part 1: Foundational Concepts
What is an organized study / test / procedure used in science and other fields to test a hypothesis? -Experiment What is a hypothesis? -Basic: Educated Guess ??? Not a Good Response!!! How do you develop a hypothesis? -Observation and Prior Knowledge When it comes to a hypothesis, what is the main objective the researcher is trying to accomplish? -Accept or Reject The Hypothesis (Which One???)
Forming and Testing Hypotheses In science a hypothesis is a tentative answer (explanation) to a well-framed scientific question It is usually a rational accounting for a set of observations It leads to predictions (likely outcomes) that can be tested by performing experiments
Textbook Method Scientific Process 1. Make an Observation 2. Ask a Question 3. Form a Hypothesis that Answers the Question 4. Make a Prediction Based on the Hypothesis 5. Do an Experiment to test the Prediction 6. Analyze the Results 7. Hypothesis Supported or Not Supported (Repeat 1 to 7 when needed) 8. Report Results (Lab Report | Publication)
The Flexibility of the Scientific Process The scientific method is an idealized process of inquiry Hypothesis-based science is based on the textbook scientific method but rarely follows all the ordered steps Backtracking and “rethinking” may be necessary part way through the process
