Water Moves Soil
Explain gullies, washed-out dirt, and the hole under a gutter.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 15
- Welcome to Wind and Water Works! Water and wind are always changing the land, sometimes right in your own yard.
- When rain runs downhill, it carries loose soil with it. Over and over, it can cut a ditch called a gully.
- Look under a gutter's downspout. Water pouring out in every storm can wash away the soil and leave a hole.
- Carrying soil and rock away is called erosion. Breaking rock into smaller pieces is called weathering.
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.)
