In this lesson, learners will use images to observe and compare the surfaces of two comet nuclei from close range. Separate teachers guides and students guides are provided. Supplementary resources needed for the lesson are provided and include... (View More) scientist and student audio tracks, and images of Wild 2, Tempel 1, and Hartley 2. (View Less)
This is a legacy site for videos and animations related to the Deep Impact mission and encounter with Tempel 1. Learners can watch videos about the mission, encounter, science, and results.
In this activity, learners replicate the scientific processes of observing, forming an explanation, revising and communicating about a model of a comet. Learners construct a model of features of a comet using an assortment of common craft supplies.... (View More) This activity relates to several NASA comet missions such as Deep Impact, Stardust, Stardust-NExT, and EPOXI and can be used to emulate a process that scientists and engineers follow on all missions.

Learners can read about the Deep Impact mission to encounter comet Tempel 1, including the mission, the experiment, results, the comet, the team, and how the results were transmitted back to Earth. Includes pre- and post-encounter fact sheets.
In this online interactive, learners will explore how scientists learn about the composition of an asteroid by studying energy and neutrons that emanate from it. Includes audio (and transcription) explaining the diagram.
This is a lesson about the characteristics of planets, comets, asteroids, and trans-Neptunian objects. Learners will classify objects and then apply what they have learned by participating in a formal debate about a solar system object discovered by... (View More) the New Horizons spacecraft and by defining the term planet. (View Less)
Leonard Nimoy narrates this a video about NASA's Dawn mission to the asteroids Vesta and Ceres. Learners will follow the mission from paper to launch pad to asteroid belt and beyond. The video features the planning, instrumentation and technological... (View More) challenges of this unique mission. Note: This video was produced pre-launch in 2007. For the latest news and science go to the Mission website under Related & Supplemental Resources (right side of this page). (View Less)
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 a lesson about the science supporting the design and operation of an ion propulsion engine. Learners will study the concepts of formation and discharge of charged particles, attractive and repulsive forces between charged particles, and the... (View More) properties of ions in the plasma phase. The lesson may or may not be completed on-line. This is activity 2 of 5 in Structure and Properties of Matter: Ion Propulsion. (View Less)
