Birdseed Mining

In this activity you will use seeds to model mining valuable materials from rocks.

Build a Model Aquifer

The United Nations includes clean water and sanitation in its sustainable development goals. Many places face severe water shortages. The Geoscientists Without Borders® (GWB) program supports teams to collaborate with communities to solve problems, including water shortages.

GWB scientists use geophysical techniques to find underground layers of sediments or rock that contain enough water to be drilled for water wells. These kinds of rock layers are called aquifers. In this activity you will build a model aquifer.
