Here you will find resources to help educators and their students interpret and describe how weathering, transportation, and deposition occur in your local stream, describe your parkland site in terms of its relation to the river system and the water cycle, develop a scaled drawing of your parkland site that shows its relationship to Earth systems and cycles.

Here you will find resources to help educators and their students interpret topographic maps to identify large and small streams within your community, understand the nature of a drainage basin, analyze maps to identify the drainage basin in which your community is located, evaluate important interactions between communities and river systems.

Here you will find resources to help educators and their students describe and classify sediments according to particle size and shape, describe what happens to sediments composed of different rock types as they are transported in streams, understand the relationship between stream velocity and particle size, understand the relationship between transport distance and particle size.

Here you will find resources to help educators and their students use models and real-time stream-flow data to understand the characteristics of low-gradient streams, understand how models can help scientists interpret the natural world, identify areas likely to have low-gradient streams, describe hazards of low-gradient streams.

Here you will find resources to help educators and their students use models and real-time stream-flow data to understand the characteristics of high-gradient streams, identify characteristics of high-gradient streams, calculate stream slope or gradient, identify areas likely to have high-gradient streams, identify possible hazards and benefits of a high-gradient stream on a community.
