Understanding Ecosystems: Erosion and Flooding
Students study the balance in the environment needed for ecosystems. They discuss what can lead to erosion and flooding.
Curated OER
Secrets in a Grain of Sand
Students working in small groups examine beach sand to discover signs of erosion, weathering, ocean currents and waves. They present their findings to the class.
Curated OER
Geology
Pupils, in groups, observe the effect of water and ice on surface features of the land. They alsoexplore erosion and deposition.

Class Conservation Corps (CCC)
Students investigate how the loss of soil, a valuable natural resource, affects their lives through loss of productive land to grow food, loss of coastal land mass, and poor water quality from runoff. They design a project to keep soil...

Looking At Water: a Walking Field Trip
Fourth graders observe the effects of water on the soil and record those effect by drawing sketches of water erosion and conservation practices.
Curated OER
Where Has All The Top Soil Gone?
Students investigate changes caused by water flowing over soil.

Junior Engineering Surface Water
Students experience the effects of pollution and erosion on a model of a watershed and explore ways to change the outcome.
Curated OER
Junior Engineering Retaining Walls
Students name the properties of sand as related to the properties and the building of retaining walls. They build a retaining wall and state how retaining walls are used.
Curated OER
Go With the Flow
Students experiment with a simulated river bed and examine how erosion takes place faster with a young, fast-moving river than with a slow, older river.
