This is a reading strategy guide in a series of guides that utilizes articles from the Great Explorations in Math and Science (GEMS) program. These strategy guides provide teachers of middle school students with a reading strategy (in this case,... (View More) Teaching Vocabulary Awareness) and supplemental resources, background information on that strategy, connections to standards, classroom implementation techniques, tips for utilizing this strategy with students with dyslexia, and a two-page reading based on a particular space science concept. The reading incorporated into this strategy guide, "Observing Stars," describes the process scientists use to observe and collect evidence about the life cycle of a star. Students will encounter the following challenging terms in this article: remnants, nebula, nebulae, supernova, and neutron star. This strategy guide is also mapped to the Common Core State Standards for English Language Arts Literacy in Science & Technical Subjects, Grades 6-8. (View Less)
In this activity, students use multiwavelength images of stars in different stages of evolution to investigate how the initial masses of the protostars determines their evolutionary paths. Images include stellar nurseries, protostars, supernova... (View More) remnants, planetary nebulae, white dwarfs, neutron stars, pulsars and black holes. The activity includes a teacher guide with background information, a card set of 24 images, student task description and worksheets, online tutorials, and a Web quest version. Suggestions for using the activity in the classroom as well as related URLs are included in the Web-based teacher guide. (View Less)
In this activity, students are reminded that the Universe is made up of elements and that the heavier elements are created inside of a star. They are then introduced to the life cycle of a star and how a star's mass affects its process of fusion and... (View More) eventual death. Students discuss the physical concept of equilibrium as a balancing of forces and observe an experiment to demonstrate what happens to a soda can when the interior and exterior forces are not in equilibrium. An analogy is made between this experiment and core collapse in stars, to show the importance of maintaining equilibrium in stars. Finally, students participate in an activity which demonstrates how mass is ejected from a collapsed star in a supernova explosion, thereby dispersing heavier elements throughout the Universe. This activity is part of a series that has been designed specifically for use with Girl Scouts, but the activities can be used in other settings. Most of the materials are inexpensive or easily found. It is recommended that a leader with astronomy knowledge lead the activities, or at least be available to answer questions, whenever possible.

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)
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) set the Crab Nebula into motion. This is Activity 2 of the "Supernova Educator's Guide" developed by the XMM-Newton and GLAST E/PO programs. The guide features background information, assessment rubrics, student worksheets, extension and transfer activities, and alignment to national education standards. Note: In 2008, GLAST was renamed Fermi, for the physicist Enrico Fermi. (View Less)
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) GLAST E/PO programs. The guide features extensive background information, assessment rubrics, student worksheets, extension and transfer activities, and detailed information about physical science and mathematics content standards. Note: In 2008, GLAST was renamed Fermi, for the physicist Enrico Fermi. (View Less)
In this science literacy extension students read and analyze two different articles about XMM-Newton discoveries involving neutron stars and their magnetic fields. This is Activity 4 of the Supernova Guide developed by the XMM-Newton and GLAST E/PO... (View More) programs. The guide features extensive background information, assessment rubrics, student worksheets, extension and transfer activities, and detailed information about physical science and mathematics content standards. Note: In 2008, GLAST was renamed Fermi, for the physicist Enrico Fermi. (View Less)
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) resource consists of a manual and software for the Introductory Astronomy Lab Exercise, from CLEA (Contemporary Laboratory Experiments in Astronomy). The manual includes introductory activities for students, background information, an instructor's guide, a student handout, an answer key, a software user's guide, and a glossary. The student section of the activity starts on page 13. See Related & Supplemental Resources for a link to download the software. Note: the software is only available for Windows. (View Less)
