TRANSCRIPT
Lunar AtmosphereAtmospheric Pressure: 3 × 10−15 atm
(.000000000000003 times smaller than the Earth’s)~Nearly a Vacuum~
Sources of atmosphere come from • Sputtering: bombardment of solar winds ions that
release atoms of Sodium and Potassium• Outgassing: Argon – 40, Polonium – 210, and
Radon - 222 released during radioactive decay in the crust and mantle
• Capture: of Helium – 4 from the solar wind

Lets do the Moon Dance:
A kinesthetic approach to learning
the times that the phases of the moon
rise, set and are highest in the sky.
• Rules– Your right hand is the sun– Your left hand is the
Moon– To your left is East – To your right is West– The angle between the
SUN – EARTH – MOON system must stay constant for a given lunar phase.
