In “Crucial Concentration” students develop skills using micropipettes and the spectrophotometer to determine the amount of protein in three solutions of unknown concentrations, using the Lowry Assay.

An alternative version of this module is available integrating the theory of evolution. The lab portion is also the Lowry Assay.

The estimated time to complete this lab is:

Prelab: 1.0 hours

Laboratory: 2.0 hours

This lab is recommended for students in grades 7-12.
