The Solar System & Magic Planets
The Solar System
Divide the class into ten groups to represent the nine planets plus a spaceship. Ask the nine groups to find spaces in the classroom and assemble as much information as they can on their respective planets (Jupiter, Saturn, Uranus, Neptune, Earth, Venus, Mars, Mercury and Pluto). The tenth group consists of space travellers who visit the nine planets after conducting research on their spaceship. Each group can then enter its research findings in the class Space Log.
Tell your students you're going to conduct a scientific experiment together. They'll need some clear soda, a glass and a few grapes. Ask them to fill the glass with soda, drop in the grapes and watch to see what happens next. The air bubbles will carry the grapes to the surface, but once the bubbles pop, the grapes will sink back to the bottom of the glass. Explain that if the grapes were planets, they would move in space the same way but would be propelled around the Sun by the power of gravity. Explain the difference between gravity and hydraulic energy (operated, moved, or effected by means of water).
