This is a make-it-yourself planisphere designed to show where Kepler is pointing. Learners can use it to locate exoplanets around stars in the night sky. It comes with two wheels: one with coordinate grid for plotting additional exoplanet stars and... (View More) one without grid that is easier to read; and two holders for varying latitudes (one for 30°-50° and one for 50°-70°). The product is updated approximately annually to incorporate improvements and any newly discovered planets orbiting naked eye stars. (View Less)

This paper model shows the orbit of Comet ISON (late 2013) with respect to the innermost planets of the solar system. After reading background information about comets - how they form and where they come from - students cut out and tape together the... (View More) pieces of the model provided to show its orbital pathway (a single page of parts that can be assembled using just scissors and adhesive). Links are provided to related classroom activities and additional resources. (View Less)

This is an activity about how much atmospheric pressure is needed on Mars to maintain surface water and why it does not have surface water today. Learners will use a computer interactive to learn about Mars past and present before exploring the... (View More) pressure and greenhouse strength needed for Mars to have a watery surface as it had in the past. (View Less)

This is an activity about the atmospheric conditions (greenhouse strength, atmospheric thickness) Mars needs to maintain surface water. Learners will use a computer interactive to learn about Mars past and present before exploring the pressure and... (View More) greenhouse strength needed for Mars to have a watery surface as it had in the past. (View Less)

This is an activity about the way distance, albedo, and atmosphere affect the temperature of a planet. Learners will create a planet using a computer game and change features of the planet to increase or decrease the planet's temperature. They will... (View More) then discuss their results in terms of greenhouse strength and the presence of liquid water. (View Less)

This is an activity about the way distance, reflectivity, and atmosphere affect the temperature of a planet. Learners will create a planet using a computer game and change features of the planet to increase or decrease the planet's temperature.

Learners will explore Jupiter's origins through three stories. First, they model their own lifetimes by tying knots in lengths of yarn to represent key events in their pasts. Then, children listen to and act out a cultural origins story, such as the... (View More) Skytellers stories told by Native American master storytellers. Finally, they explore Jupiter's story by modeling a timeline from today back to its "birthday." They use the timeline to visually demonstrate that the Big Bang occurred much earlier in the past. Children will discover how the Juno mission to Jupiter will help unveil how our solar system - including Earth - came to be. The activities are from 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 is a lesson about the Moon's Copernicus Crater. Learners will use observation to make their own geologic map of the Crater. They then identify crater features in a photogeologic image and use those observations to color their map with the... (View More) appropriate geologic units. (View Less)
