Scientific Notation and Unit Conversions

Mrs. Reese introduces unit conversions and scientific notation, explaining their importance in scientific measurements. She discusses how scientific notation helps in representing very large or small numbers and provides a detailed guide on using calculators for these calculations. The video also covers SI prefixes and their role in making units more manageable, along with practical examples of unit conversion using the KUPS method.
