In this activity students construct Log Tapes calibrated in base-ten exponents, then use them to derive relationships between base-ten logs (exponents) and antilogs (ordinary numbers).  This is activity B1 in the "Far Out Math" educator's guide.... (View More)

This Hubble Space Telescope image shows the colorful aftermath of the death of a Sun-like star: a planetary nebula. The text describes how this planetary nebula may have formed. In the accompanying educational activity, In Search of ... Planetary... (View More)

In this activity students develop a simplified log table using information from their Log Tapes. Then they use it to solve arithmetic problems by looking up and combining logs, and finding the antilog. Because these problems are extremely simple,... (View More)

This online module features an interactive model of the the Milky Way galaxy. Students click on parts of the model to read and learn about the different components of galaxies. Upon completion of this activity, students will be able to locate parts... (View More)

In this interactive, online activity, students estimate the distances of objects in the Hubble Deep Field from Earth using the relationship between size, brightness, and distance. Students can complete this activity independently or in small groups.... (View More)

Audience: Middle school

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 interactive, online activity allows students to examine the Hubble Deep Field image and simulate the process astronomers have gone through to classify the objects in it. Students classify select objects in the image based on observable... (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)

Using real data from NASA's Fermi satellite, students determine the size and energy of an active galaxy flare region. This activity includes background information for teachers, student worksheets, procedures, adaptations, extensions, an assessment... (View More)

Audience: High school, Higher education
Materials Cost: Free

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)
