# The Crawl of the Crab

In this activity, students compare two images of the Crab Nebula taken more than 40 years apart. By measuring the motion of some of the knots of glowing gas in the neubla, students will be able to determine the date of the supernova explosion that... (View More)

# Magnetic Poles and Pulsars

Students investigate magnetic fields in two and three dimensions, and compare the magnetic field of a pulsar to that of the Earth and other astronomical objects. This is Activity 3 of the Supernova Educator Guide developed by the XMM-Newton and... (View More)

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

# Dying Stars and the Birth of the Elements (CLEA lab)

In this activity, students will use a simulator of an orbiting X-ray observatory to observe a supernova remnant, the expanding gas from an exploded star. They will take X-ray spectral data, analyze them, and answer questions based on that data. This... (View More)

# Newton's Law of Gravitation

The two activities included in this guide introduce students to the principles behind Newton's Law of Gravitation. The guide provides teachers with background information, preparation suggestions for each activity, as well as material lists, and... (View More)

# Newton's Second Law of Motion: Force, Acceleration and Velocity

This educational wallsheet provides several simple illustrations of Newton's Second Law. In the activity included, students study the motion shown in the drawings to decide how it relates to the object's velocity, whether or not the velocity is... (View More)

# Newton's Third Law of Motion: Actions and Reactions

This educational wallsheet illustrates Newton's Third Law of Motion. The accompanying activity is an experiment in which students create a balloon and straw rocket. Students must figure out how to shoot the balloon from the back of the classroom and... (View More)

# Exploring the Spectrum

This activity introduces students to the visible light spectrum, and demonstrates what happens to the appearance of an image when certain wavelengths of light are blocked by filters or made visible using special tools. Students are lead through... (View More)

# A Multi-Wavelength Exploration of the Universe

In this activity, students explore images taken with telescopes sensitive to several different wavelengths of the electromagnetic spectrum. Students compare the images to determine that light carries information about physical features in the... (View More)

# Evidence for the Expanding Universe

In this activity, students examine the first line of evidence, galactic motion, for the notion of an expanding universe. By examining the spectrum of light from a galaxy, students can determine whether a galaxy is moving toward or away from us, and... (View More)
