Rocks and Minerals

• Rocks can be sorted by physical properties: texture, color, hardness, and size.

• Texture: rough, smooth, bumpy, sharp

• Color

• Hardness: soft (chalk) or hard

• Size: sand(smallest), gravel, pebble, boulder(largest)

• Size (measured using a ruler)

• All rocks are solids

The Moon

• The moon is a satellite that orbits around Earth.

• The moon gets its light from the sun.

• The moon moves though all of its phases in about a month

• The moon moves from new moon(no light), to first quarter (right light), to full moon, to last quarter(left light) and continues in this pattern.

• You should use a calendar to record the appearance of the moon's phases

The Sun

• The sun is a star.

• The sun creates light and heat for Earth

• The sun is highest in the sky at noon.

• The sun follows the same pattern every day.

• The sun rises (sunrise) in the east and sets in the west (sunset).
