Georgia Performance Standards:
• S3E1. Students will investigate the physical attributes of
rocks and soils.
• M3D1. Students will create and interpret simple tables
and graphs.
• ELA3R3 The student uses a variety of strategies to gain
meaning from grade-level text.
What do you know about rocks?
• Where do rocks come
from?
