In these activities, students investigate how gamma ray bursts emit energy in beams (as opposed to emitting light in all directions) and investigate the implications of this on the total number of gamma ray bursts seen in the universe. This activity... (View More)

Audience: High school

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 build a model of an active galaxy. From this, they will learn about the geometry of the components of an active galaxy and develop an understanding that different viewing angles can lead to dramatically different... (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 activity focuses on the question, What do active galaxies look like when viewed from different distances? Students work in small groups to learn about the small angle formula, construct a template, and use it to correctly measure the angular... (View More)

Materials Cost: $1 - $5 per group of students

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 interactive, online activity, students practice estimation skills as they begin to explore the Hubble Deep Field image. Students first give a rough estimate of the number of objects in the image. They then use representative sampling... (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)

This is an activity about telling time. Learners will construct a northern-hemisphere star clock and will set their star clocks based on the position of the Big Dipper in the sky. Then, they will use their star clocks to predict where the Big Dipper... (View More)
