Celestial bodies-objects in space: asteroid, planets,

Celestial Body Movements:
Rotate-Earth spinning on its axis—causes day and
night (day)
Revolve- Earth moving around the sun – causes
years
Movement Direction: Prograde rotation and
revolution - to the left
Lunar Phases- visible parts of the moon
New moon, waxing crescent, first quarter, waxing
gibbous, full moon, waning gibbous, third quarter,
waning crescent… be able to identify
Focus on the RIGHT:

Dark - waning

Spring Tide-highest of the high tides-new and full
moons-180°
Neap Tide-Lowest of the low tides- 1st and 3rd
quarter moons- 90°
High Tide and Low Tide-regular level tidescrescents and gibbous moons
Eclipses- one celestial body casts a shadow on
another celestial body
Lunar Eclipse-Earth cast shadow on the moon (LEM)
Solar Eclipse-Moon casts a shadow on the Earth
(SaME)
Why don’t we have a lunar or solar eclipse every
month? The moon’s orbit is off from the Earth’s
orbit by 5°
Seasons--winter, spring, summer, fall, wet and dry
Be able to identify seasons and hemispheres
(Northern (NA) and Southern)
Why do we have seasons? The Earth’s tilt (23.5°) on
its axis AND its revolution around the sun give us
seasons.
Compare and contrast lunar and solar eclipses to
new and full moons…
