# Calculating with Scientific Notation - Comparing Populations

Students will use population data from the U.S. Census Bureau to read and write numbers in scientific notation and to make comparisons of that data for states and decades. Students will also write ratios of the populations of their school’s state in different decades, determine if the ratios show a pattern, and make a scatter plot of the data.
