Middle School Solar System Model
1.) Eclipses: Lunar and Solar
Observe eclipses
the saros cycle; eclipses are predictable
Earth's shadow on the moon; moon's shadow on the Earth
sizes and distances of the sun and moon (scale modeling)
telescopic observations of the moon; the moon is a rock
2.) Planets
observe planets as wandering stars
add orbiting planets to the model
evidence for orbital order
evidence of other moons
3.) Tides
what are tides
their regular patters
correlation with the moon (and sun)
moon must exert some force
gravity and the tidal "bulge"
add gravity to the model
4.) Seasons
Seasons in different parts of the world
sun's apparent position in the sky (e.g. Lahaina noon)
angle between north star and the sun's path (23.5 degrees)
spin axis
angle of incoming sunlight
axis fixed in direction
The Solar System
Dwarf planets & asteroids
consolidate solar system model
6.) Stars
the Milky Way in the sky
Messier objects
"spiral nebulae"
galaxies
distance to the nearest stars (relative to our scale model)
