This article describes an alternative way of testing--a performance assessment--that is different both in process and goals from typical tests, but closer to what teachers believe assessment should be. Teachers who have helped to create, refine, and use this new generation of tests find them valuable because they measure the skills and concepts…

The relationship between specific gravity, salinity, and density in brine solutions is investigated. Students construct hydrometers to reinforce concepts learned in oceanography. Background information, salt requirements for the unknowns, directions, and reproducible worksheets are included. (KR)
