I've Got That Sinking Feeling: Investigating Enzymes

Overview:   In this lab, students will examine the effect of catalase concentration on the rate of hydrogen peroxide breakdown. This lab can be easily expanded to include student-centered investigations.

Curriculum Connections:  enzyme function, factors that can influence enzyme-catalyzed reactions, serial dilutions

Experimental Timing:  From start to finish this lab can be completed in a single 55-60 minute class period.  For additional information, see "Instructor Planning Guide" in the Teacher Materials.

Specialized Equipment Required: non-treated 24-well plates • fruit fly vials or clear scintillation vials • p20 and p1000 micropipettes (optional)
