Parents, there are only three days of school this week. We are off on Thursday and Friday for Winter Break.
Science
This week's Georgia Performance Standards:
S6E1 Students will explore current scientific views of the universe and how those views evolved.
c. Compare and contrast the planets in terms of
• Size relative to the earth
• Surface and atmospheric features
• Relative distance from the sun
• Ability to support life
d. Explain the motion of objects in the day/night sky in terms of relative position.
e. Explain that gravity is the force that governs the motion in the solar system.
S6E2 Students will understand the effects of the relative positions of the earth, moon and sun.
a. Demonstrate the phases of the moon by showing the alignment of the earth, moon, and sun.
b. Explain the alignment of the earth, moon, and sun during solar and lunar eclipses.
c. Relate the tilt of the earth to the distribution of sunlight throughout the year and its effect on climate.
S6E3 Students will recognize the significant role of water in earth processes.
d. Explain the causes of waves, currents, and tides.
