In this activity students use log tapes and base-two slide rules as references to graph exponential functions and log functions in base-10 and base-2. Students discover that exponential and log functions are inverse, reflecting across the y = x axis as mirror images. This is activity E2 in the "Far Out Math" educator's guide. Lessons in the guide include activities in which students measure, compare ... Full description.

In this activity, students graph second and third order functions, discovering an inverse relationship between squares and square roots and between cubes and cube roots. Students graph these functions on both linear grid (evenly spaced numbers), and a log-log grid (evenly space exponents). Graph lines that curve on linear grids transform into straight lines on the log-log grids, with slopes equal ... Full description.

This is an activity about the Aurora Borealis or Northern Lights. Learners will plot the Auroral Oval in the northern hemisphere and determine the height of the northern lights using Carl Stormer's triangulation method. This activity corresponds to the NASA CONNECT video, titled Dancing in the Night Sky, and has supplemental questions to support the video viewing. Full description.
