This activity begins with a guided note section that may be completed by the students as a pre-lab activity or by the teacher through lecture or demonstration. Students are provided with a list of factors that may impact enzyme activity, and are challenged to work in groups to design an experiment to test an assigned factor. Students will complete their experiment, and share the results with their classmates. Students will use this information to complete a chart outlining the effect of each factor and an explanation of its impact. This activity challenges students to "think like a scientist" and prepares them for the new AP Biology exam.
