Riverwalk Bridge: Choose the Right Marker Material

Use measured and observed properties to identify materials and judge a design.

Read the material records

Read the report and study the reference table. The pieces were the same size, so their measurements can be compared.

A Safer Route Across the Riverwalk Bridge

A city bridge has a wide walkway beside the traffic lanes. After rain, the painted route markers become hard to notice. The bridge team wants to add small markers along the walking path. The markers should stay attached in wet weather and should bend around the walkway rail without cracking. Students test equal-size pieces of four reference materials before making a recommendation.

The team observes color, surface texture, flexibility, and whether a magnet pulls each piece. The team measures each dry piece, then measures it again after the piece is soaked, blotted, and weighed. The difference between the two masses is called water gain. The same piece size, soaking time, blotting steps, and balance are used for every reference piece.

The team wants a quick test that separates the steel piece from the aluminum piece. Which test is most useful?
