In this chapter, you will be introduced to the steps of the scientific method. You will learn the International System of Units (SI) and how to use dimensional analysis for converting between units. Precision and accuracy are defined and you will practice expressing numbers with appropriate significant digits and in scientific notation. Finally, you will learn about the four steps of problem solving: analyze, plan, solve, and evaluate.

In this chapter, you will learn: to describe the steps of the scientific method to explain basic safety rules for working in the chemistry lab to identify metric units of measurement to explain what causes uncertainty in measurements to use significant digits and scientific notation to calculate percent error to explain dimensional analysis and conversion factors
