Students compare weight of dried and fresh food. Students trace their bodies and color portions to represent the amount of water their bodies contain.
Students build water wells in gravel aquifers, and pump their wells using eye-droppers.
They will see how aquifers can be drawn down and recharged of water, and learn how water quality in an aquifer can be impacted by human activities. In the Wiggling Water game, students simulate groundwater recharge by pretending they are water droplets moving through different soil and rock types. Students will demonstrate that water moves easily through some earth materials and with great difficulty through others. Using the large Lake Superior Floor Map, students will locate the countries, states, and communities that are part identify and locate rivers within the Lake Superior Basin, then identify the area included in the Lake Superior watershed. Students will understand the role of rivers in determining the boundaries of the Lake Superior watershed.
