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. This lesson is part of Project Spectra, a science and engineering education program focusing on how light is used to explore the Solar System. (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. This... (View More) lesson is part of Project Spectra, a science and engineering education program focusing on how light is used to explore the Solar System. (View Less)

This is an activity about lunar and terrestrial stratigraphy. Learners will study the patterns of lava flow by creating eruptions using soda-vinegar solutions and modeling with home-made playdough (stove-top and no-cook recipes are included). This... (View More) activity is in Unit 2 of the Exploring the Moon teacher's guide and is designed for use especially, but not exclusively, with the Lunar Sample Disk program. (View Less)

Learners will research and document some of the requirements for mounting an expedition to an asteroid; actively explore potential resources available to space travelers through research, assessment, team cooperation, and exploration simulations;... (View More) develop the background to make the connection between meteorite research and potential planetary resources; and map and core an edible asteroid. Materials lists, and advanced preparation and procedural tips are included. This is lesson 17 of 19 in Exploring Meteorite Mysteries. (View Less)
