Activity Prep

Print Prep

In this lesson, students construct an explanation about a surprising phenomenon: the existence of underground water. In the activity, Wanted: A Well, students play a game in which they must obtain and combine information about groundwater in order to select the best site to build a town. They evaluate the features of the landscape, plants in the area, and clues from the soil and then decide where to dig a well.

Plant & Soil Clues worksheet 1 per group
Wanted: A Well worksheet 1 per group
Prep Instructions

We suggest students work in groups of four. If there are just a few students, they can form a smaller group. A solo student can do the activity alone, but we think it’s more fun with friends.

Set up Aquifer Stations (Optional)

Since there’s so little prep for the main activity in this lesson, we suggest you consider making Aquifer Stations, as described in the Extensions section. These will give students a chance to experiment and observe how water is stored underground.
