The lithograph features illustrations, statistics and science goals of the James Webb Space Telescope. The accompanying classroom activity prompts students to use the images and text to generate questions about the telescope. Students then research... (View More) those questions on the Internet and present their findings. (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... (View More) and infrared cameras to see that objects opaque to light at one wavelength, may be transparent to light of a different wavelength. 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)
In this activity, students learn that infrared light is reflected in the same manner as visible light. Students align a series of mirrors so that they can turn on a TV with a remote control when the remote is not in a direct line with the TV. As a... (View More) result of their experiment with reflection, students deduce that infrared light is another form of light and is a part of the electromagnetic spectrum. 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 a TV and remote control. It is the third 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 learn that light carries information. Students also discover that infrared (IR) radiation is a form of light that in some cases behaves like visible light and in other cases behaves very differently. For example, some... (View More) objects that block visible light allow infrared light to pass through. This activity requires the use of both common classroom materials (e.g., laser pointer) and special materials (e.g., photocell). It is supported by teacher notes, information on materials and preparation, background information on student misconceptions, an activity sheet, an answer key, and a pre-assessment activity. This activity is the last of four activities in the "Active Astronomy" educator's guide. Activities in the guide are designed to complement instruction on the electromagnetic spectrum with a focus on infrared light. The activities build upon each other and are best taught in order.

This is an activity about the Doppler effect. Learners begin by simulating the noise made by a passing siren. After learning that the change in pitch results from movement, they investigate the definition of frequency, calculate change in frequency,... (View More) and learn how this applies to light and the study of astronomy. This lesson requires a Doppler ball, also referred to as a buzzer ball. (View Less)
Learners will investigate, discuss, and determine why humans have always explored the world (and now space) around them. Students determine these reasons for exploration through a class discussion. In the first activity, students use the Internet to... (View More) examine the characteristics of past explorers and why they conducted their exploration. They then examine why current explorers - including the students themselves - want to explore other worlds in the Solar System. By the end of the lesson, the students can conclude that no matter what or when we explore - past, present, or future - the reasons for exploration are the same; the motivation for exploration is universal. Note: The MESSENGER mission to Mercury that is mentioned in this lesson ended operations April 30, 2015. For the latest information about MESSENGER and NASA's solar system missions see the links under Related & Supplemental Resources (right side of this page). (View Less)
Learners will explore the physical characteristics of comets by reaching into a series of boxes and feeling the materials and structures within. They will describe what they observe and speculate on comet characteristics being modeled in each box,... (View More) opening the discussion about the nature of these icy bodies and begin to compare them to other members of our solar system.Note: See Related & Supplemental Resources (right side of this page) for links to assembly instructions and worksheets needed to complete this activity.

This is a unit in 7-8 sessions about objects outside of our solar system, including galaxies and the universe. Learners will investigate the contents of the universe, why light years are used to measure distances in space, the lifespan of a star,... (View More) and detecting extrasolar planets. Finally, they will examine evidence for habitable worlds beyond earth. This is Unit 4 of the GEMS Space Science Sequence for Grades 6-8, which is available for purchase (see related link).

This is a lesson about the evidence for life on other planets. Learners will play a game to examine processes in cellular metabolism and explore both direct and indirect evidence for fingerprints of life. Includes teacher notes, learning objectives,... (View More) and assessment of prior knowledge and preconceptions. This is Lesson 2 in Exploring Deep-Subsurface Life. Earth Analogues for Possible Life on Mars: Lessons and Activities. (View Less)
