Powers of ten: on your own Create a table with three columns: “power of ten”, “thing studied”, and “branch of science” � In the powers of ten column, list the following seven rows: 9 or more, 6 to 8, 2 to 5, 1 to -1, -2 to -5, -6 to -8, -9 or less � For each range of powers of ten, come up with at least one thing studied that would fit that size scale and assign what branch of science it is studied in �

Powers of ten: with your group Compare the lists you created. What things did multiple people list? What’s unique? � Is there a pattern in what branches of science are listed at each of the levels? �Pick someone to represent your group and report your results to the class in a few minutes �
