In this hands-on activity, students analyze the data on Mystery Object Cards, observe that astronomical objects have many observable properties, and discover that these properties allow scientists to categorize astronomical objects into different... (View More)

In this activity students convert antilogs to logs, and logs to antilogs using scientific notation as an intermediate step. They will thereby develop a look-up table for solving math problems by using logarithms. This is activity D2 in the "Far Out... (View More)

In this activity students construct multiplying slide rules scaled in Base-10 exponents and use them to calculate products and quotients. They will come to appreciate that super numbers (exponents, orders of magnitude and logarithms) play by... (View More)

This interactive, online activity allows students to explore Hubble's deepest surveys of the far universe and distant galaxy surveys made by Hubble and other observatories. This activity includes science content reading material for the online... (View More)

Audience: Middle school

In this interactive, online activity, students view an image of an "oddball" object from the Hubble Deep Field image that has been difficult for astronomers to classify. Students make their own interpretations of the object based upon knowledge... (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 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)
