# Ironing Out Curves

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)

# Stellar Statistician

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)

# Cosmic Classifier

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)

# Building Perspectives with Active Galaxies

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)

# Light Travel Time and the Size of Active Galaxies

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)

# Zooming In on Active Galaxies

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)

Audience: High school
Materials Cost: \$1 - \$5 per group of students

In this activity, a three-part questionnaire launches students into discussions about where objects in space are located, and when they formed - an introduction to the concepts of structure and evolution of the universe. By physically manipulating... (View More)

# Mars 2003: Closest Approach

These two images, taken 11 hours apart with NASA’s Hubble Space Telescope, reveal two nearly opposite sides of Mars. Hubble snapped these photos in 2003 as the red planet was making its closest approach to Earth in nearly 60,000 years. In the... (View More)
