Wind Moves Sand and Soil
Explain ripples, drifts, and dunes made by wind.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 16
- Wind can't move a heavy rock, but it can move dry, loose sand and soil.
- On a windy day, the wind pushes sand into little waves called ripples.
- At the beach, wind piles sand up, grain by grain, into big hills called dunes.
- When fields are dry and bare, wind can blow the soil away as dust.
Georgia Standards of Excellence in Science:
- S3E1.c — Make observations of the local environment to construct an explanation of how water and/or wind have made changes to soil and/or rocks over time. (Clarification statement: Examples could include ripples in dirt on a playground and a hole formed under gutters.)
