In this activity, students construct base-two slide rules that add and subtract base-2 exponents (log distances), in order to multiply and divide corresponding powers of two. Students use these slide rules to generate both log and antilog equations,... (View More)

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... (View More)

In this activity students construct Log Rulers, finely calibrated in base-10 exponents and numbers (logs and antilogs). They practice reading these scales as accurately as possible, listing all certain figures plus one uncertain figure.  This is... (View More)

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... (View More)

In this activity, the teacher sets up three simulated clouds representing three different cloud types. Students use different methods to estimate precipitation contents of each cloud type. Each method is roughly analogous to methods actually used... (View More)

This article contains a series of kinesthetic activities, explaining and demonstrating why stars twinkle and what astronomers can do to minimize it. The activities can be used to demonstrate how Earth's atmosphere distorts starlight and how advanced... (View More)
