Purpose

At this activity center, there is a model of an aquifer, which is any soil through which groundwater moves easily. The model illustrates the subsurface (sand, gravel and bedrock aquifers and aquitards) and its relation to the surface water (lakes and rivers). A pump  can be used to change the amount of precipitation in the system. Water moves continuously through the model from higher to lower elevation (due to gravity). There are several wells to demonstrate the effect of pumping on an aquifer.

Ensure that students understand the key terms highlighted in the activity by using them in several different contexts throughout the presentation.

Key Messages

  • Groundwater does not run in underground rivers; it percolates through sand and gravel
  • Groundwater is a source of drinking water through wells
  • Pollutants on the ground or in lakes will enter groundwater and percolate through it, contaminating drinking water
