Standards:
S3E1 Students will investigate the physical attributes of rocks and soils. a. Explain the difference between a rock and a mineral. b. Recognize the physical attributes of rocks and minerals using observation (shape, color, and texture), measurement, and simple tests (hardness). c. Use observation to compare the similarities and differences of texture, particle size, and color in top soils (such as clay, loam or potting soil, and sand). d. Determine how water and wind can change rocks and soil over time using observation and research. Essential Questions: • What are minerals? • What are rocks? • How are rocks and minerals alike and different? • How do scientists classify rocks? • How do scientists classify soils? • How is soil formed? • How do wind and water change rocks and soil over time?
