Science Lab: Weathering and Erosion.
Fourth graders have been learning about the effects of weathering and erosion on different land forms and along rivers/ oceans.
We built a shore, mountain, and river valley from wet sand. Students simulated erosion in different stations. It was very messy and very fun!
River Valley erosion
Chemical Erosion: Students tested vinegar on limestone and nails. They demonstrated physical erosion with sand paper and chalk.
Mountain Erosion: Students used a spray bottle on a mountain of sand.
Wind Erosion: Students used straws and dry sand to show wind erosion.
Lab reports.
Wave erosion: students created waves with plastic cards against wet sand to show weathering on a beach.
