Land and Water

During this unit, students will learn that water is recycled by natural process on Earth and erosion and deposition result from the interactions among air, water, and land.

  • Investigate the effects of slope, flow, and natural land formations on erosion and deposition.
  • Design and build models of landscapes, predict how a landscape will affect the flow of water, and relate these modeled effects to land and water interactions on earth.
  • Recognize the role humans play in planning and designing landscapes that take into account the natural interactions of land and water.

Ecosystems and Change in Stability of An Ecosystem

Students learn that organisms in ecosystems have dependent and independent relationships and that natural and human-made events can disturb an ecosystem.
