Erosion and Deposition
by Anonymous
Change slope, rainfall, or grass cover one at a time to see where soil is eroded and where it piles up.
About this app
Erosion and Deposition is an elementary science exploration app about how rain and slope move soil. Compare hill conditions by changing rain intensity, steepness, and vegetation, then use fair-test rules to isolate one variable at a time. A final challenge lets learners protect hills with grass, terraces, and stone walls while staying within a budget.
Use cases
- Elementary students learning about erosion and deposition
- Teachers introducing fair tests and controlled variables
- Learners comparing the effects of rain, slope, and vegetation
- Classroom activities on ways to reduce soil erosion
Features
- Interactive hill cross-sections showing soil being worn away and deposited
- Comparisons of light or heavy rain, gentle or steep slopes, and bare or grassy ground
- Fair-test challenges where only one condition should differ
- Protection challenges using grass, terraces, and stone walls
- Gauges for erosion, moved soil, deposited soil, goals, and budget
- Reset and next-step controls across four scenarios per activity
