This resource is designed to enable presenters (scientists, engineers, etc.) to easily present to an elementary and/or middle school audience and feel confident that the information they are presenting is developmentally appropriate and supports the... (View More) Next Generation Science Standards. A PowerPoint Presentation includes talking points and suggestions, a “Best Practices” document to offer helpful suggestion before, during, and after the presentation, and a list of additional resources that may be accessed by the speaker and/or the educator. This presentation is designed to take 30 to 45 minutes. (View Less)
In this lesson, students will explain CRaTER's purpose and how it works. They will also design (using paper and pencil) a cosmic ray detector to answer their own questions. CRaTER's purpose is to identify safe landing sites for future human missions... (View More) to the moon; discover potential resources on the Moon; and characterize the radiation environment of the Moon. The lesson includes background information for the teacher, questions, and information about student preconceptions. This is lesson 4 of 4 from "The Cosmic Ray Telescope for the Effects of Radiation." (View Less)
In this lesson on cosmic rays, students will explain two examples of a cosmic ray detector. Includes information about student preconceptions and a demonstration that requires a geiger counter and optional access to a small radioactive source that... (View More) emits energetic helium nuclei (alpha particles), e.g., the mineral the mineral autunite, which contains uranium. This is activity two of four from The Cosmic Ray Telescope for the Effects of Radiation (CRaTER). (View Less)
In this lesson about cosmic rays, students will describe why cosmic rays are dangerous to astronauts. Includes information about student preconceptions. This is activity 3 of 4 from The Cosmic Ray Telescope for the Effects of Radiation (CRaTER).
This is a lesson/briefing about the Dawn mission and the significance of its ion propulsion system. Learners will consider cases of science fact versus science fictions, study the challenges of the Dawn mission, and apply the "History Frame"... (View More) strategy to investigate the who, what, when and how in the history and development of ion propulsion. This is activity 1 of 5 in Structure and Properties of Matter: Ion Propulsion.

This is a lesson about the path of one xenon ion through an ion propulsion engine. Learners will focus on what a single xenon ion sees and does as it goes through the reactions and processes that provide the ion jet propulsion engine's thrust. They... (View More) will learn to adopt an informed, experimental method for use in a later lesson. A tightly-scripted slide-by-slide presentation is provided. Preconceptions are discussed. This is activity 4 of 5 in Structure and Properties of Matter: Ion Propulsion. (View Less)
This is an annotated children's story about the Dawn mission to Vesta and Ceres in the asteroid belt. Learners will dissect the story for real and fictional objects and places in the solar system, and for those scientific concepts or processes that... (View More) may be true. Support materials include the story with space for kids to illustrate, an audio recording of the story by the author and an extension activity. (View Less)
