Part 1: Introducing the Earth, Moon, and Sun Simulation
Talk with your partner as you explore the Earth, Moon, and Sun Simulation. Share what you both notice.
Identify the function of the following simulation tools:
Where does the Moon get its light? (check one)
What evidence from the simulation supports your answer?
CFS:
Accurately identifies the light on the moon based on its position
Accurately describes the relationship between light and the appearance of illuminated objects
Accurately describes connections to the source of evidnece
"I know the moon gets light from _________ because .... "

Why does the moon appear brighter on the left half of the moon from a top view?
What causes the moon to appear brighter on the left half of the moon from a top view?
CFS:
Accurately identifies the light on the moon based on its position
Accurately describes the relationship between light and the appearance of illuminated objects
"I know the moon gets light on the left half because .... "
(think: where is the sun? Why is the right side dark? )
