Fourth graders have been studying weathering, erosion, and deposition. They collected used soda bottles to perform an experiment with their classroom and science teacher to demonstrate how people can take measures to prevent losing soil to erosion.

First, they collected dirt and made hills and mountains inside their soda bottle environment models.  Then they sprinkled water over them and collected the runoff to examine what happened.  Next students collected organic matter and rocks near the streambed to try to prevent erosion and repeated the experience.

They then looked at the streambed itself to see how erosion and deposition resulted in the shape of the banks.  The kids loved connecting real life examples to their understanding of science principles.
