This document outlines a lesson on scientific notation. It provides examples of numbers written in scientific notation, such as 1 x 10^8 and 1.54 x 10^-11. The rules for converting between scientific notation and standard form are explained. To write a number in scientific notation, the decimal is placed after the first non-zero digit and multiplied by 10 to an exponent reflecting how many places the decimal was moved. To convert to standard form, the decimal is moved right or left the number of places indicated by the exponent.
