Students will learn about black holes through reading a NASA press release and viewing a NASA eClips™ video segment. Then students will use tables and mathematical expressions to compare black hole sizes and temperatures. Common Core State... (View More) Standards for Mathematics and English Language Arts are identified. This activity is part of the Space Math multi-media modules that integrate NASA press releases, NASA archival video, and mathematics problems targeted at specific math standards commonly encountered in middle school textbooks. The modules cover specific math topics at multiple levels of difficulty with real-world data and use the 5E instructional sequence. (View Less)

Students will learn about NASA's Fermi satellite and gamma ray sources through reading a NASA press release. They will also learn about gamma rays and the electromagnetic spectrum by viewing a NASA eClips™ video segment. Then, students will use... (View More) percentages to explore the origins of mysterious gamma ray sources in the sky using NASA Fermi data. Common Core State Standards for Mathematics and English Language Art are identified.

In this lesson, students simulate an experiment in which the discovery of dark energy can be made by plotting modern supernova distances on a Hubble Diagram. Data is provided in an Excel spreadsheet (see related resources). In order to complete this... (View More) activity, students should be familiar with Hubble's Law and the concepts of absolute luminosity, apparent luminosity, and Doppler shift (particularly redshift). This activity can be done using either a computer graphing program or manually with graph paper. This lesson is part of the "Cosmic Times" teacher's guide and is intended to be used in conjunction with the 2006 Cosmic Times Poster. (View Less)

Students explore the evidence for dark matter using the measurements made by the ROSAT X-ray satellite for a small group of galaxies. Prerequisite knowledge: students should be familiar with the Law of Universal Gravitation and able to work with the... (View More) formulas for kinetic and potential energy and the Law of Conservation of Energy. This lesson is part of the Cosmic Times teachers guide and is intended to be used in conjunction with the 1993 Cosmic Times Poster. (View Less)

The goal of this lesson is for two groups of students to exchange information (e.g., through poster presentations, Podcasts, debates, or PowerPoint presentations) about how two different theories explain a natural phenomenon: Newton's Law of... (View More) Gravitation and Einstein's General Theory of Relativity. The lesson will also illustrate how the scientific process allows a new, more complete theory to take the place of an older theory that does not produce accurate results for a new discovery. Students will need to have either studied both Newton's Law of Gravitation and Einstein's Theory of Relativity or be given the time and resources to look up this information. This lesson is part of the Cosmic Times teachers guide and is intended to be used in conjunction with the 1919 Cosmic Times Poster. (View Less)

This educational wallsheet illustrates Newton's First Law of Motion. In the related activity, students will discover the properties of inertia and motion, and see how they have very important real-life applications. The activity includes background... (View More) information, pre-activity reading, pre-activity discussion questions, an assessment, and post-activity extension activities that tie student observations back to the Swift satellite. This is the first of four posters on Newton's Laws. (View Less)

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) universe. Students also determine that, because light of different wavelengths comes from different physical sources, combining multiwavelength views helps astronomers develop a more complete picture of the universe and the objects in it. This activity is one of several in the "Cosmic Questions Educator's Guide," a guide developed to support the Cosmic Questions exhibit. The activities in the guide can be used either in conjunction with or independently of the exhibit. (View Less)

This activity is one of several in which students are required to access and analyze actual data from NASA missions, including video "interviews" with real NASA scientists, to solve a mystery. In this mystery, students learn about the force of... (View More) gravity and how scientists analyze data by studying the properties of different objects in space. Live! From 2-Alpha can be used to support instruction about forces and motion, origin and evolution of the universe, and the interaction of energy and matter. This activity is one of several in "Space Mysteries," a series of inquiry-driven, interactive Web explorations. Each Mystery in "Space Mysteries" is designed to teach at least one physical science concept (e.g. interactions of energy and matter, structures and properties of matter, energy, motion, or forces), and is accompanied by materials to be used by classroom teachers.

This activity is one of several in which students are required to access and analyze actual data from NASA missions, including video "interviews" with real NASA scientists, to solve a mystery. In this mystery, students are challenged to determine if... (View More) a signal from space has a natural origin, or if it actually is a message from aliens. Alien Bandstand can be used as a supplemental learning tool to reinforce the scientific method, and as an example of how scientists analyze data in real-world situations. It is one of several activities within "Space Mysteries," a series of inquiry-driven, interactive Web explorations. Each Mystery in "Space Mysteries" is designed to teach at least one physical science concept (e.g. interactions of energy and matter, structures and properties of matter, energy, motion, or forces), and is accompanied by materials to be used by classroom teachers.

Gamma-ray bursts are distant explosions that briefly outshine the rest of the gamma-ray universe. In this lesson, students will follow the same procedures used by today's astronomers to determine two basic facts about gamma-ray bursts: their... (View More) distance from Earth and their power.
