Using three images from the Wide-field Infrared Survey Explorer (WISE) mission, students measure and analyze infrared light from objects to identify Brown Dwarfs and Ultra-Luminous Infrared Galaxies (ULIRGs). The lesson includes a teacher’s guide,... (View More) student worksheet and PowerPoint presentation (which contains the three images to be analyzed). (View Less)

Dieter Hartmann, a high-energy physicist, presents a story-based lesson on the science of Gamma-Ray astronomy. The lesson focuses on gamma-ray bursts; examining their sources, types, and links to the origin and evolution of the Universe. The... (View More) story-based format of the lesson also provides insights into the nature of science. Students answer questions based on the reading guide. A list of supplemental websites is also included.

NASA scientist, Neil Gehrels, serves as your guide to this online lesson on gamma ray tools, which focuses on advances in detector technologies since the 1980s that have enabled us to capture and image high-energy phenomena. Dr. Gehrels explains... (View More) different methods for detecting and imaging high-energy particles, how they work, and the advantages and disadvantages of each, using examples and imagery from NASA missions. (View Less)

The H-R diagram is a scatter graph of stars, a plot of stellar absolute magnitude or luminosity versus temperature or stellar classification. It is an important astronomical tool for understanding how stars evolve over time. Stellar evolution cannot... (View More) be studied by observing individual stars as most changes occur over millions and billions of years. Astrophysicists observe numerous stars at various stages in their evolutionary history to determine their changing properties and probable evolutionary tracks across the H-R diagram. In this activity, students plot both maxima and minima with corresponding stellar classifications for several variables, and then identify the type of variability: Cepheid, RR Lyrae, Mira or Semiregular. This activity includes background information, a teacher guide, a student activity, and accompanying worksheets. The American Association of Variable Star Observers (AAVSO) and The Chandra X-Ray mission have collaborated to develop this activity. (View Less)

In this hands-on activity, students learn about the different realms of the Universe and explore their sizes and relative scales. They will be guided through a process that uncovers the immense sizes of the Sun, Solar System, Solar Neighborhood,... (View More) Milky Way, Local Group, Supercluster, and the observable Universe. The full version of this activity involves students doing simple math computations, however it can also be done without the math. There are some inexpensive materials involved, as well as a powerpoint presentation. It is intended for grades 8-12, but can be adapted down for lower grade levels. (View Less)

In this activity, students are introduced to light and colored gels (filters). Students make and test predictions about light and color using gels; learn about the importance of gels (filters) to astronomers; then analyze images taken with regular...

Section 1 of the activity guide includes teacher notes, information on materials and preparation, student misconceptions, and a student pre-test. Each activity section also includes teacher notes, student activity sheets, and answer keys. This activity is the first of four activities in Active Astronomy, which are designed to complement instruction on the electromagnetic spectrum, focusing on infrared light. (View Less)

In this activity, students build a photocell detector, and use it to detect different colors of light in a spectrum. Then they place the detector just outside the red region of the visible light spectrum and see that the detector detects the... (View More) presence of light there, even though there is no color visible. Students learn that invisible light exists and that we can detect this light with instruments other than our eyes. In a final part of the activity, students investigate the infrared signals emitted by TV and VCR remote controls. The activities build upon each other and are best taught in order. Section 1 of the activity guide includes teacher notes, information on materials and preparation, student misconceptions and a student pre-test. Each activity section also includes teacher notes, student activity sheets, and answer keys. This activity requires some special materials (e.g. a small solar cell, alligator clip leads, plus common classroom materials (e.g., overhead or slide projector). This activity is the second of four activities in Active Astronomy, which are designed to complement instruction on the electromagnetic spectrum, focusing on infrared light. (View Less)

These directions allow students to open different images that have been collected from the ROSAT satellite. The directions instruct the user to open the website, but first the user will need to Install Hera using the tab found under the Overview...

In this lesson, students create a fictional narrative on the beginning of time. They use their scientific knowledge of the Big Bang Theory and go back into time to when it occurred so they can make observations about it. Students can select from... (View More) four options for creating a final product that demonstrates their learning using the RAFT (Role, Audience, Format, and Topic) method.

This series of curriculum support materials and classroom activities explores how our understanding of the nature of the universe has changed during the past 100 years. Students examine the process of science through the stories of the people and... (View More) the discoveries that caused our understanding to evolve from a static universe to a universe whose expansion is accelerating. The series illustrates the nature of science by tracing the process of discovery from the confirmation of Einstein's theory of gravity, to Hubble's evidence for the expanding universe, to the detection of the microwave background, and finally to the discovery of dark energy. The series includes six posters, each resembling the front page of a newspaper from a particular time in this history with articles describing the discoveries. Each poster is accompanied by an online teacher guide and 4-5 downloadable, inquiry-based lessons. Downloadable newsletter versions of the poster are available for individual student use, with three editions for different reading levels (Early Edition for 7-8 grade readers, Home Edition for 9-10 grade readers, and Late Edition for 11-12 grade readers). Lesson plans can be found by following the link from Teacher Resources to Curriculum Tools to Sortable Table of the Lessons. (View Less)
