8th Grade Performance Task

Contributed by: RAND
Designed by: University of California, Santa Barbara, Stanford University, and The Far West Laboratory

In the third part of Acids and Bases - Vinegar, entitled "Text," students read about an experiment conducted by another but does not use any apparatus. In that experiment, the student uses a Universal Indicator Color Guide to measure the strength of acids and bases, as well as what happens when acids and bases are mixed together. Additionally, the student decides which of three solutions of unknown pH will neutralize a fourth solution of unknown pH. Students have to apply this process to a problem involving a vinegar and an unknown vinegar solution.
