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)

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)
