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. 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 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 how much atmospheric pressure is needed on Mars to maintain surface water and why the planet does not have surface water today. Learners will use a computer interactive to learn about Mars past and present before exploring...

Learners will weigh themselves on scales modified to represent their weights on other worlds to explore the concept of gravity and its relationship to weight. They consider how their weights would be the highest of all the planets while standing on... (View More) Jupiter, but their mass remains the same no matter where in the solar system they are. They compare the features of different planets to determine which characteristics cause a planet to have more or less gravity. This activity 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)

These short leader guides are designed for a novice user to pick up and implement the activities with ease. They address a range of topics all related to asteroids - most especially Asteroid Vesta. Activities are tagged to quickly find ones that are... (View More) active (involves movement), edible (involves food), calm (stationary) or informative (about NASA's Dawn mission and Vesta).
