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.

This activity is an interactive word find game with words related to comets and NASA's Comet Nucleus Sample Return mission. Accompanying text and pictures describe what comets are and why we are interested in them.
This is an activity about comet composition. Learners will explore the physical characteristics of comets by reaching into a series of boxes and feeling the materials and structures within. They will describe what they observe and speculate on comet... (View More) characteristics being modeled in each box, opening the discussion about the nature of these icy bodies and begin to compare them to other members of our solar system. (View Less)
This is an lesson about comets. Learners will create a physical timeline of comet appearances in art and literature throughout history. Participants use a set of photos depicting comets in art images and science missions and place the images in... (View More) chronological order, while learning about the perceptions of comets during that time period. (View Less)
Learners will shrink the scale of the solar system to the size of their neighborhood and compare the relative sizes of scale models of the planets, two dwarf planets, and a comet as represented by fruits and other foods. This activity requires... (View More) access to a large indoor or outdoor space (measuring at least 190 feet wide) where the children can model the orbit of Mercury around the Sun. It is part of Explore! Jupiter's Family Secrets, a series designed to engage children in space and planetary science in libraries and informal learning environments. (View Less)
This 24 minute planetarium show teaches about meteors, meteorites, asteroids, and comets. The show was created for fulldome theaters, but is also available on DVD to be shown in flat version for TVs and computer monitors, and can be freely viewed... (View More) online. It shows the effects of the Chixulub and Tungusta events, plus the Pallasite impact that resulted in the Brenham meteorite fall, and describes ways that asteroid hunters seek new objects in the solar system, and how ground penetrating radar is used to find meteorites that have survived to the Earth's surface. Narrated by astronaut Tom Jones, it also discusses ways that humans might try to deflect an asteroid or comet that is on a collision course with Earth. The show was created for informal science venues (digital planetariums); it is also useful as supplemental material for middle school science. Impact Earth is available for free if presented directly from the Space Update site (widescreen or fisheye views linked from YouTube). Otherwise, a DVD of the show can be purchased for $10.
