Artifact 5: Lactase Inquiry Lab
During the macromolecule unit, students completed an inquiry style lab in which they investigated enzyme activity in a variety of conditions. For this lab, students had to write their own hypotheses and design their own investigation procedures. Different lab groups investigated different conditions. Some student-designed investigations included changing temperature (hot vs. cold vs. room temperature), pH level (acidic vs. basic vs. neutral), and enzyme source (lactase pills vs. probiotic pills). This lab incorporated aspects of collaboration and discussion as well as scientific literacy competencies.
