This module is about collaboration and communication strategies that are used during mission design. Learners will strengthen their understanding of and ability to use collaborative processes and communication practices to clarify, conceptualize,... (View More) and make decisions. They will compare the risks of varying courses of action that confront scientists and engineers. After the risks are identified, they will gather and convey evidence supporting and refuting the viability of these actions, and reach consensus. The module strategies rely primarily on student investigation into the background information that is necessary to support arguments; make quantitative risk analyses; engage in debate, role-playing, and persuasive writing/communication processes; and practice group decision-making procedures.

In this lesson, students observe the surface of rotating potatoes to help them understand how astronomers can sometimes determine the shape of asteroids from variations in reflective brightness.

This is a lesson about the design and operation of an ion propulsion engine. Learners will study the essential components and variables of an ion propulsion system. Activities include an on-line ion propulsion engine simulation and design. Included... (View More) are changes in energy and fuel consumption as a result of variable changes (dependent/independent variable relationships). This is activity 5 of 5 in Structure and Properties of Matter: Ion Propulsion. (View Less)

This is an activity about motion in a frame of reference. Learners will develop an understanding that motion is relative by reading the text "Frames of Reference." As a follow-up to the reading, students engage in a writing-to-learn strategy that... (View More) can help them understand how motion depends on specific frames of reference, as they are asked to assume a specific frame of reference and describe motion in relation to multiple perspectives. This is activity 3 of 5 in "Structure and Properties of Matter: Ion Propulsion." (View Less)

This is a lesson about ice worlds in the outer planetary regions and the role they play in understanding the Solar System. Learners will role-play stories connecting science-related literature to ice worlds, view and interpret space-based images of... (View More) ice worlds, and investigate surface and interior features of outer planetary ice worlds. Photometry and spectroscopy will be used as background. Activities include small group miming, speaking, drawing, and/or writing. This is the lesson 11 of 12 in the unit, Exploring Ice in the Solar System. (View Less)

This is a lesson about radiation and the various sources of radiation that a spacecraft may encounter in its journey. Learners will calculate their annual exposure to high-energy radiation, identify sources of high-energy radiation, and explain why... (View More) the near-Mercury environment is a concern for the Mercury MESSENGER mission. This is lesson 2 of 4 in the high school track of a module, titled Staying Cool. Note: the student guide starts on p. 17 of the PDF. (View Less)

This is a activity about applying the scientific method to a design challenge. Learners will design and build a platform that will be placed on a heat source. The platform is expected to serve as an insulator for a cube of gelatin. The goal is to... (View More) keep the inside temperature of the gelatin cube as cool as possible. Materials cost will vary, depending on materials chosen by group (within budget set by the teacher). Ties are made to the Mercury MESSENGER mission.
