During the last sunspot cycle between 1996-2008, over 21,000 flares and 13,000 clouds of plasma exploded from the Sun's magnetically active surface. These events create space weather. Students will learn more about space weather and how it affects... (View More)

This article describes an approach designed to decrease math anxiety and teach students about the use of mathematical symbols simplifying radicals. A deck of cards is used in a demonstration, and a problem set using real life examples to master the... (View More)

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)

This is an activity about digital imagery and technology. Learners will create a picture using graph paper containing ones and zeroes and instruct others to reproduce it without showing it to them, just like digital technology. After, in groups,... (View More)
