Grade 3 Science · World 1: Rock Hounds · Level 2
Color and Texture
Describe a rock's color and texture (smooth, rough, or grainy).
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 2
- Start by looking: what color is the rock? Rocks can be gray, black, white, brown, red, pink, and more.
- But careful: color can fool you. Quartz can be clear, white, pink, or purple, so color alone isn't enough.
- Texture is how a rock feels. Smooth rocks feel even, like a river pebble. Rough rocks have bumps and edges. Grainy rocks have specks you can see and feel.
Georgia Standards of Excellence in Science:
- S3E1.a — Ask questions and analyze data to classify rocks by their physical attributes (color, texture, luster, and hardness) using simple tests. (Clarification statement: Mohs scale should be studied at this level. Cleavage, streak and the classification of rocks as sedimentary, igneous, and metamorphic are studied in sixth grade.)
