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)

This is a demonstration about the density of the planets. Learners will compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods. They will then dunk the "planets" in water to highlight the fact... (View More)

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)
