Sorting Rocks
Classify rocks by one or two properties, using a data table.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 6
- Scientists classify rocks by sorting them into groups by their properties.
- Choose one property, like luster, and make a group for each kind: metallic or nonmetallic.
- Scientists record test results in a data table. Each row is a rock, and each column is a property.
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.)
