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 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)."
In this lesson, students will learn how cosmic rays were discovered and what they are - including their size and speed. Includes background information for the teacher, questions, activities and information about student preconceptions. This is...

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 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 an activity about vectors and velocity. It outlines the addition and subtraction of vectors, and introduces the application of trigonometry to describing vectors. The resource is designed to support student analysis of THEMIS (Time History... (View More) of Events and Macroscale Interactions during Substorms) Magnetometer line-plot data. Learners will complete worksheets consisting of problem sets that allow them to work with vector data in magnetic fields. This is activity 15 from Exploring Magnetism: Earth's Magnetic Personality.
