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 an activity about spacecraft radio communications. Learners will explore spacecraft radio communications concepts, including the speed of light and the time-delay for signals sent to and from spacecraft. Learners measure the time it takes... (View More) for a radio signal to travel to a spacecraft using the speed of light, demonstrate the delay in radio communication signals to and from a spacecraft, and devise unique solutions to the radio-signal-delay problem. In an extension, learners are asked to calculate the distance the spacecraft traveled. All NASA spacecraft missions have a telecommunications system and use radio waves to transmit signals. The context for this activity is sending a command to the New Horizons spacecraft telling it to take a picture of Pluto. Includes teacher background, adaptations, and student data sheets. (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.
