Introduction to Chemistry - Chapter Summary and Learning Objectives

Watch the video lessons in this chapter to explore the roles creativity, curiosity, and skepticism play in scientific research. Find out how to design an experiment, gather evidence in the lab, and report your findings. Instructors can also help you discern the relationships between your own research and current scientific knowledge. By the end of this chapter, you should be familiar with the following:

  • Objective nature of scientific inquiry
  • Steps in the scientific method
  • Differences between scientific laws and theories
  • The role of hypotheses in experimentation

Video Objective
What is Chemistry? - Definition & Science Overview Discusses the importance of empirical evidence and observation in understanding and explaining the natural world. Lesson content also defines chemistry and provides a brief overview of the field.
The Scientific Method: Steps, Terms & Examples Describes the basic model of how science works in the field and in the laboratory. Lesson content outlines six key steps, beginning with the formulation of a question and hypothesis and ending with the analysis of data gathered from experimentation and observation. Feedback loops that cause scientists to reevaluate their findings and formulate new questions are also discussed, as is the importance of community and peer review in scientific research.
Hypothesis, Theory, Prediction & Law in Science Compares and contrasts the differences between hypotheses - tentative explanations proposed for a select set of observations - and theories, which are statements that can be used to explain or predict more general phenomena. The breadth of scientific laws used to describe universal relationships is also discussed.
