This workshop will give participants hands-on experience with an inquiry lab on paper labware.  Authentic scientific practices, such as designing experiments, performing repeated cycles of testing and evaluation of hypotheses, and communicating intermediate and final results, are difficult to teach using standard lab methods such as buret titrations because of the time and safety constraints in the undergraduate lab.  We have developed paper microfluidic “labware” that allows students to safely do experiments very rapidly at low cost and with low waste generation. The paper labware used in this demonstration is an acid-base titrator that contains small amounts of a stable acid embedded in several paper squares. <br/> <br/>In this 60 minute workshop, you will use the titrator to determine the concentration of an unknown base.  We will also discuss how an instructor would typically deliver and assess an inquiry-based lab.  There will be time for discussion about how to structure a lab course to prepare students for success in learning science practices.
