Comparing Numbers in Scientific Notation

This lesson builds on the previous understanding of scientific notation by teaching how to compare numbers in this form. It uses the example of planetary distances from the sun to illustrate the importance of exponents and coefficients. The lesson also covers the comparison of numbers with negative exponents, using gravity as an example. Students are given exercises to reinforce their understanding.
