This hands-on project enables students to model erosion and deposition processes with a stream table. Observing how water interacts with soil will enhance their understanding of landform development and environmental science.
If a stream table is created with varying slopes and soil types, then the rate and patterns of erosion and deposition will differ.

Set up the stream table or plastic bin to mimic a riverbed.
Add varying amounts of sand and gravel to create different slopes.
Slowly pour water into the stream table to simulate rainfall.
Observe and document how the water interacts with the soil.
Note areas of erosion and deposition after each simulation.
Change the slope and repeat the process to compare results.
Collect any sediments in containers for analysis.
Discuss findings on how different landscapes affect erosion.
Different slopes and soil types will yield varying rates of erosion and deposition. Students will gain insights into how landscapes evolve over time due to water flow.
Slope of the stream table
Amount of erosion and deposition
Volume of water used, Soil composition, Duration of water flow
Use caution with water to prevent spills, and ensure the workspace is safe and clean.
Create a visual demonstration of your stream table setup.
Use charts to illustrate the differences in erosion between slopes.
Prepare a slideshow explaining the science behind erosion and deposition.
Engage your audience with a Q&A about real-life erosion issues.
Display collected sediment samples with labels.
