Summary:Wetlands are called one of the world's most productive ecosystems. They produce more plant and animal life than woodlands or prairies. Characteristics, like water levels, naturally change seasonally and annually. Wetlands are in transition between aquatic and terrestrial systems where the water table is usually at or near the land surface or the land is covered by shallow water. Since wetlands do not always appear wet, they are not always recognized. Along with the presence of water at or near the surface and evidence of hydrophytic (water-loving) vegetation, wetlands have hydric soils present. Hydric soils have a spherical soil component surrounded by air spaces occupied by water. In this activity, students will create two ecosystems (one with constantly draining soil, and another with constantly wet soil). The students will observe the two ecosystems and note their findings.
