About this worksheet

What students practice

Students compare model solutions that reduce damage from coastal flooding and earthquake shaking.
Students use test results and cost limits to recommend hazard protection solutions.
Students support predictions about hazard solutions with evidence and identify limits of model tests.

How to use

Read the planning report together, then have students use both graphs to compare solutions. Discuss why model results help planning but do not guarantee safety.

Safer Visits to Cove Point

Compare model results and predict how hazard solutions could help.

1. Compare Flood Protection

Read the report. Use the flood graph to compare the designs. Model cost points are for comparing classroom designs, not real construction prices.

A Plan for Cove Point

Cove Point has tide pools beside a low beach. A visitor station stores maps and first-aid supplies near the path. During strong coastal storms, seawater can flood the low ground. Earthquakes can also shake the station and make loose supplies fall. The park team wants to compare ways to reduce these effects.

A fourth-grade class built models to help the team think about its choices. For the flood test, students made a beach in a tray and marked a visitor area. They compared four designs: no protection, a low wall, a raised path, and a low wall with a raised path.

For each design, students slowly poured two cups of room-temperature water from the same place. They kept the tray slope, beach shape, visitor area, and pouring time the same. They collected and measured the water that reached the marked area. Each design was tested once. The graph shows these measurements in milliliters, or mL.

The designs had model costs: no protection cost 0 points, the low wall cost 2, the raised path cost 4, and the wall with the raised path cost 7. For its first plan, the class wanted no more than 50 mL to reach the visitor area while spending no more than 5 points.

For an earthquake model, students placed six lightweight foam blocks on a small shelf attached to a movable cardboard platform. The blocks represented supplies. Students compared four ways of holding the supplies. They used the same shelf, blocks, starting positions, and gentle shaking pattern. They counted how many blocks fell.

The models did not copy every possible storm or earthquake. Park visitors must still follow official warnings and leave when directed. A protected path or secured shelf is not a reason to remain at the beach during a hazard warning.
