Flooded Town Command Center

Grades 3-560-75 minSource: Creative Dad Company

Kids build a model town on a slanted tray, pour on rainfall, and watch where the water pools and floods before redesigning the drainage system to protect the buildings. It turns watershed science into a hands-on rescue mission with a satisfying before-and-after payoff.

Setup

Place common or recycled supplies for Flooded Town Command Center on one work surface and choose a safe area for the test. Read the four activity directions aloud; drawings, paper models, and household substitutes may replace specialized materials, and no digital tool is required.

Activity

  1. Build a clay landscape with hills and a town, then predict where rain poured from a cup will flow and pool.
  2. Construct the town's buildings and roads on the landscape, then add a first attempt at drainage channels.
  3. Test the design by pouring water evenly over the town, then redesign the channels or add barriers when a neighborhood floods anyway.
  4. Present the before-and-after flood maps to the town council and explain which drainage changes kept the most buildings dry.

Done when: The group produces the Flooded Town Command Center solution, completes the described test, makes the revision called for by the evidence, and supports its final explanation with an observed or measured result.

Materials

plastic tray or bin, clay or sand for terrain, small cardboard buildings, cups of water, straws or clay for channels, food coloring
