Chemistry Journal 01.01 The Science of Chemistry Driving Question: How does science help us understand events in the natural world, and what is chemistry's role in understanding these interactions? Key Ideas and Terms Notes FQ: What knowledge is considered science? What does the field of composition and structure of materials and the changes they chemistry study? undergo. Define phenomena. observable events or occurrences; What is science? based on empirical observations, experimentation, and explanations based on logical reasoning. an observation verified by experimentation or experience rather than theory What are empirical observations? Describe each of these characteristics of science: Observable Testable Replicable Reliable Flexible What is bias? a prejudice in favor of or against one thing, person, or group FQ: What questions can be answered by science? What are two things you can look for to determine if a question can be answered by science? What are some examples of testable and non-testable questions? FQ: How do I investigate questions using science? What is the scientific method? Question: What type of question can the scientific method attempt to answer? Research: Why is it useful to do background research before you write and test a hypothesis? Hypothesis: What is a hypothesis, and why is it important to a scientific investigation? Test: Describe the test (experiment) step of the scientific method. What is an independent variable? Give some examples from hypotheses and investigations. What is a dependent variable? Give some examples from hypotheses and investigations. What are controlled variables, and why are they important? Give some examples of controlled variables from hypotheses and investigations. Analysis: Describe how results are analyzed after an experiment. What is inference? Where in the scientific method do you make inferences? FQ: What makes science reliable? What is included in reliable science? What does it mean to be replicable? repeatable? What are characteristics of “bad” science? Give an example of each characteristic. A lot of new vocabulary is introduced and used in this course. Practice to become more familiar with all the new terms and definitions. Also, develop responses for the lesson's focus questions to be sure you understand the content.
